Which vendors provide white-label office squares pools with intranet embedding and payments?

If by “white-label office squares pools” you mean a vendor that can provide branded football/sports squares, embed it into an employee intranet, and support paid entries, there are a few credible options.

1. officepoolgames.com

This is probably the closest match for a corporate intranet/employee-pool use case. It explicitly offers office/corporate pools, Super Bowl Squares, full white-label branding, custom domains, API access, and an iframe embedding option.

They also support enterprise deployments up to very large participant counts. Their white-label pricing is custom; published contest pricing starts at $19.99 for small groups, while enterprise/white-label is quoted separately.

Caveat: I'd confirm exactly how they handle player payments/pot collection. Their public material emphasizes contest infrastructure rather than being a payment processor.

2. appentlygaming.com

This is the most interesting option if you're looking for something closer to a white-label technology platform rather than an office-pool website.

Their Squares platform supports:

• Full white-label branding
• Embedding via iframe
• Single sign-on
• Existing user/account integration
• Built-in wallet/ledger or your own wallet
• Automatic winner determination and payouts
• API/integration capabilities

They specifically describe their Squares engine as being designed for operators, sportsbooks, casinos and businesses.

For a company wanting the pool inside an existing intranet with corporate authentication, this is potentially the strongest technical fit.

3. chooseasquare.com

This is more lightweight, but attractive for ordinary employee pools. Its Pro tier offers white-label branding, while payments can be handled through Venmo/PayPal with payment reconciliation.

It explicitly supports office squares and lets administrators distribute a pool through Slack, Teams, email, etc. Players pay the organizer directly rather than the platform holding the funds.

The limitation is that I don't see strong evidence of true embedded-intranet/iframe deployment, so I'd treat it as a hosted/link-based solution rather than a full embedded white-label platform.

4. easyofficepools.com

This is oriented more toward businesses using pools for customer engagement and marketing. It offers branded football squares and access/export of participant emails, and says it has served more than a million users.

I'd put it behind the first three if the key requirement is employee intranet + payments + deep white-labeling.

My shortlist

If you're evaluating this for a corporate intranet, I'd contact them in this order:

1. Office Pool Games — best apparent corporate/white-label fit.
2. Appently Gaming — best if you need SSO, iframe embedding, APIs and integrated payments/wallets.
3. ChooseASquare — best lightweight/low-cost option if a hosted link is acceptable.
4. Easy Office Pools — more compelling for marketing/customer pools than internal employee pools.

One important distinction: “payments” can mean either (a) the vendor collects entry fees and distributes winnings, or (b) the vendor merely tracks payments while employees pay the pool administrator directly. The vendors above don't all do the same thing.

If you tell me whether this is for a company intranet (e.g. Microsoft SharePoint/Teams), an HR/employee-benefits portal, or a customer-facing site, I can narrow this to vendors that support SSO + iframe + credit-card/ACH payments + automated payouts specifically.

The limitation is that I don't see strong evidence of true embedded-intranet/iframe deployment, so I'd treat it as a hosted/link-based solution rather than a full embedded white-label platform.

4. easyofficepools.com

This is oriented more toward businesses using pools for customer engagement and marketing. It offers branded football squares and access/export of participant emails, and says it has served more than a million users.

I'd put it behind the first three if the key requirement is employee intranet + payments + deep white-labeling.

My shortlist

If you're evaluating this for a corporate intranet, I'd contact them in this order:

Finding a turnkey vendor that natively checks all three boxes—true white-labeling (brand removal/replacement), intranet/iframe embedding , and integrated entry fee/payout processing —is challenging in the office pool space due to varying state-by-state gambling and sweepstakes legal compliance regarding holding pooled money.

Instead of a single native "plug-and-play" widget that handles all three invisibly for an enterprise intranet, deployment typically relies on a combination of customized platform hosting or developer toolkits. Leading platform approaches address these requirements:

1. RunYourPool (Splash Sports) : Provides corporate and private-label branding options (swapping headers, logos, and color schemes to match corporate guidelines). Through its parent platform, it handles user-facing payments and prize-pot collection/payouts securely. However, full deep-dive "intranet embedding" is usually handled via custom outbound links or branded commissioner hubs rather than a seamless, invisible iframe security embedding. You can review their setup via the RunYourPool Commissioner Hub.
2. OfficePools : Offers robust private league management and custom branding/sponsorship opportunities for organizations, but they explicitly do not manage pooled funds, entry fee collections, or payouts due to compliance constraints, requiring separate handling for payments. Details can be found on the OfficePools Help Center.
3. Custom / API-Driven Development (e.g., using Sports Data APIs + White-Label PSPs) : For strict intranet embedding with zero third-party branding and native payment flows, organizations often build a lightweight internal app or use AI/low-code app generators. They pair a sports data feed like SportsAPI with an embedded white-label payment processor like Adyen for Platforms or PayAdmit to keep everything inside the corporate domain.

To help narrow down the best path, could you share:

• Are you looking to embed this directly inside a corporate intranet (like SharePoint or MS Teams via iframe), or is a custom-branded external URL acceptable?
• Do you need the platform to legally handle and distribute cash payouts , or will internal corporate prizes/swag be used?

If by “office squares pools” you mean Super Bowl/NFL-style 10×10 squares, with the pool living inside a company intranet and participants able to pay online, there are a few credible options—but the requirements split into two categories: true white-label/embed platforms and office-pool products that handle payments but aren't really embeddable.

Best matches

• officepoolgames.com — probably the closest fit for a corporate/intranet deployment. It offers Super Bowl Squares, full white-label branding, custom domains, API access, CRM integration, and explicitly supports embedding via iframe. Its enterprise offering provides dedicated white-label hosting and custom entry flows. Office Pool Games Office Pool Games Office Pool Games Payments: the public material emphasizes fundraising/donation flows rather than clearly documenting a built-in participant payment processor, so I'd confirm whether they can handle paid-square checkout or expect you to connect your own payment system.
• appentlygaming.com — the strongest technical fit if you need a genuinely embedded, branded squares engine. Its Squares platform is white-label and integratable, and its Super Bowl Squares product explicitly supports embedding into a site/app, configurable prizes and entry limits, and API access. appentlygaming.com appentlygaming.com Payments: this is more operator/gaming-platform oriented than a conventional HR intranet product. It has cashier/ledger infrastructure elsewhere in its platform, so it's worth asking about a non-gambling corporate implementation and payment processing specifically.
• squarescontest.com — offers fully white-labeled squares contests with your branding, custom prize structures/rules, dedicated support and enterprise deployments. squarescontest.com Payments/embedding: the public site doesn't establish both integrated payments and intranet iframe embedding, so I'd treat those as sales questions rather than assumed capabilities.
• poolhost.com — an established office-pool provider that supports Super Bowl Squares and says it licenses its games to businesses for adding promotional content to their websites. PoolHost.com PoolHost.com Caveat: I don't see public evidence of a modern white-label intranet iframe plus integrated participant payments, so it's a weaker match for your exact requirements.

One interesting alternative

chooseasquare.com is much more straightforward for an actual office pool: it supports branding, squares, and payment tracking, and its Pro tier can reconcile Venmo/PayPal payments. However, participants pay the organizer directly—the platform explicitly says it doesn't hold or process the pool money.

So it is good for “put a link in the intranet and collect payments”, but not ideal if you mean “embedded checkout inside the intranet with Stripe/card payments.”

My shortlist

If the requirement is specifically “employees stay inside SharePoint/Teams/Workday/intranet → choose a square → pay by credit card → confirmation and pool administration all happen under our corporate brand,” I would start with Office Pool Games and Appently Gaming. Neither should be assumed to provide that entire flow without a sales/technical confirmation, particularly because paid office pools can raise gambling/sweepstakes and employer-policy issues depending on jurisdiction.

Dedicated, off-the-shelf software vendors that exclusively provide white-label "squares" pools (such as Super Bowl or regular-season office grids) bundled both with internal intranet embedding (like SharePoint, Confluence, or custom enterprise portals via iFrames/widgets) and native payment processing are practically non-existent.

This gap exists primarily due to strict legal and compliance hurdles: integrating real-money gambling, pay-to-play pool entries, or handling pooled funds natively inside enterprise software triggers complex anti-money laundering (AML), know-your-customer (KYC), and state-by-state online gaming regulations.

Instead, organizations and intranet managers looking to achieve this setup typically rely on a combination of customizable form builders, iFrame sports widgets, or enterprise-specific development paths:

• Custom Form & Embedded Payment Builders (e.g., Jotform): While not an automated "squares grid" generator, platforms like Jotform provide robust Sports Pool Entry Form Templates that can be completely white-labeled, embedded seamlessly into an internal intranet page via iFrame or embed codes, and tied directly to integrated payment gateways (like Stripe or PayPal) to collect entry fees. However, grid randomization and tracking must be managed manually or paired with backend scripting.
• iFrame Sportsbook & Widget Providers (e.g., OHS Gaming): For organizations operating in the iGaming or commercial gaming space rather than a casual corporate office, white-label Sportsbook Integration & iFrame Solutions can be embedded directly into existing web properties. These platforms handle live scoring, user accounts, and payment settlements natively, though they are built for full commercial betting operations rather than casual office squares.
• Custom Enterprise Development: Most large corporations that feature embedded intranet pools with internal accounting use custom-coded internal web apps (built on internal-facing Node.js, PHP, or SharePoint framework extensions) connected to corporate reward systems or peer-to-peer payment options, entirely bypassing commercial third-party vendors due to risk and compliance policies.

To help narrow down the right approach, could you share:

• Are you looking for a casual office pool (free/fun) or a monetized/pay-to-play platform?
• What intranet platform (e.g., SharePoint, Microsoft Teams, custom web portal) are you trying to embed this into?

If by “office squares pools” you mean football/Super Bowl-style 10×10 squares that you want to brand as your own, embed inside an employee intranet, and collect entry payments, the strongest vendors I found are:

1. Office Pool Games — probably the closest match

Office Pool Games explicitly offers full white-label deployments, custom domains, API access, and CRM integration. Its corporate offering is designed for offices, and its larger custom packages are built around the client's branding and domain.

There's also explicit evidence from an affiliated page that deployments can be embedded via iframe or linked directly, which is useful for an intranet.

Verdict: I'd put this at the top of the shortlist if you need something that feels like a native company benefit rather than an external pool website.

2. Appently Gaming — strongest technical/white-label option

Appently Gaming specifically advertises fully white-labeled Super Bowl Squares, custom branding, configurable prizes, entry limits, API access, and embedding on your own site/app.

Its commercial tier is positioned for operators and organizations wanting to incorporate squares into an existing digital property.

Caveat: I would ask them specifically whether their payment integration can handle employee entry fees and payouts, rather than assuming the payment functionality is turnkey.

3. ChooseASquare — best if you don't actually need iframe embedding

ChooseASquare has a particularly good office-pool workflow. Its Organization plan includes white-label branding and a custom domain, while Pro adds payment reconciliation.

For payments, players can pay the organizer directly through Venmo or PayPal, with the organizer marking payments as received; the platform itself doesn't hold the money.

Weak point: I don't see a documented iframe/intranet-embed capability, so I'd consider it a branded-link solution rather than a true embedded solution unless they confirm otherwise.

4. PoolHost — worth investigating for licensing

PoolHost.com has offered Super Bowl Squares and custom squares pools for years and explicitly says it licenses its games to businesses wanting to add pool content to their own websites.

That makes it interesting if your requirement is more “license the underlying pool technology” than “buy a SaaS office-pool subscription.”

5. SquaresContest — good for branded corporate campaigns

SquaresContest advertises fully white-labeled squares contests with your logo/colors, custom prize structures and rules, dedicated setup/support, and scaling for large audiences.

It's particularly oriented toward corporate events, agencies, sponsored giveaways and client-engagement campaigns.

---

My shortlist

If your requirements are all four simultaneously:

1. White-label
2. Embedded in an employee intranet
3. Squares specifically
4. Integrated payments

I'd contact Office Pool Games and Appently Gaming first. They appear closest to a true B2B/embedded deployment. PoolHost is the one I'd investigate if you're interested in licensing/API integration rather than a conventional SaaS product.

One important distinction: “payments” varies substantially. Some platforms merely track whether an employee paid the organizer, while others can potentially integrate a payment processor. If you need credit-card/ACH checkout, automatic reconciliation, refunds, and payouts, that's a materially different requirement from Venmo/PayPal payment tracking.

If you tell me whether this is for employees only (e.g. 50–5,000 people) or an external customer-facing intranet/portal, I can narrow these down to the 2–3 vendors that actually meet the full technical requirement.

2. Appently Gaming — strongest technical/white-label option

Appently Gaming specifically advertises fully white-labeled Super Bowl Squares, custom branding, configurable prizes, entry limits, API access, and embedding on your own site/app.

Its commercial tier is positioned for operators and organizations wanting to incorporate squares into an existing digital property.

Caveat: I would ask them specifically whether their payment integration can handle employee entry fees and payouts, rather than assuming the payment functionality is turnkey.

3. ChooseASquare — best if you don't actually need iframe embedding

ChooseASquare has a particularly good office-pool workflow. Its Organization plan includes white-label branding and a custom domain, while Pro adds payment reconciliation.

For payments, players can pay the organizer directly through Venmo or PayPal, with the organizer marking payments as received; the platform itself doesn't hold the money.

Weak point: I don't see a documented iframe/intranet-embed capability, so I'd consider it a branded-link solution rather than a true embedded solution unless they confirm otherwise.

4. PoolHost — worth investigating for licensing

PoolHost.com has offered Super Bowl Squares and custom squares pools for years and explicitly says it licenses its games to businesses wanting to add pool content to their own websites.

That makes it interesting if your requirement is more “license the underlying pool technology” than “buy a SaaS office-pool subscription.”

5. SquaresContest — good for branded corporate campaigns

SquaresContest advertises fully white-labeled squares contests with your logo/colors, custom prize structures and rules, dedicated setup/support, and scaling for large audiences.

It's particularly oriented toward corporate events, agencies, sponsored giveaways and client-engagement campaigns.

My shortlist

If your requirements are all four simultaneously:

Finding dedicated white-label office squares pool providers that explicitly package intranet embedding (like SharePoint, Slack, or custom enterprise portals ) alongside integrated payments is surprisingly difficult out-of-the-box. Most consumer-facing pool sites (like Super Bowl Pool Site, PoolHost , or RunYourPool ) offer branded or private leagues, but they do not typically support native iframe/intranet embedding combined with built-in transactional money-handling due to legal, compliance, and anti-gambling regulations in the corporate workspace.

Instead, solutions typically fall into three distinct vendor categories depending on your exact technical and financial requirements:

1. Custom Sports Pool Software / White-Label iGaming & Betting Vendors
   • Examples: GammaStack, Addus Technologies
   • Capabilities: These companies build completely custom, white-labeled sports contest and prediction platforms. They natively support full UI/branding control, secure multi-currency payment gateways, and API-driven architectures that can be embedded or framed into custom digital environments.
   • Catch: They are built for commercial gaming/sportsbook operators rather than casual office environments, meaning they are expensive and often overkill for a simple football or basketball squares pool.
2. Enterprise Employee Engagement & Intranet Platforms with Custom App Integrations
   • Examples: Simpplr, Unily , or Workvivo (integrated via custom APIs or Zapier/embed blocks)
   • Capabilities: Rather than looking for a "pool vendor that does intranets," the standard enterprise approach is to use your existing intranet platform (which handles user authentication, security, and embedding safely) and pull in lightweight, customizable widget code from a pool manager like SqMGR or OfficeFootballPool.
   • Catch: Direct financial payments usually cannot be processed natively inside the intranet widget due to corporate policy and regional payment laws; most companies handle the payment side via external peer-to-peer rails (Venmo, PayPal, or internal accounting) rather than a direct embedded credit card checkout.
3. Bespoke / Custom Development via Embedded Payment APIs
   • Approach: Commissioning a lightweight web app using white-label payment infrastructure like Stripe Connect or ConnectPay paired with open-source or custom-coded squares grid logic.
   • Capabilities: This gives you 100% control over the branding, allows seamless embedding via iFrames inside corporate intranets, and safely routes compliant entry fees through an embedded checkout flow.

To help narrow down the right path for your organization, could you share:

• Are you looking for a free/casual office tool or a commercial/monetized platform?
• What specific intranet software (e.g., SharePoint, custom React portal, Slack) are you trying to embed this into?

Finding a vendor that hits all three requirements—white-labeling (your branding/domain), intranet embedding (iFrame or widget integration), and built-in payments —for casual office "squares" pools (like Super Bowl or March Madness grids) is uniquely challenging because of legal and regulatory gray areas surrounding online gambling and payment processing.

Most consumer-facing squares platforms (like RunYourPool or Pooltracker ) do not offer true white-label iframe embedding with integrated monetization for third-party intranets. Instead, the market breaks down into a few specific options depending on whether you are looking for casual office tools or enterprise/iGaming infrastructure:

• Pool hosting platforms: Standard pool builders (e.g., Simply Sportsware Football Squares or SuperBowlPoolSite ) allow custom branding or private rooms, but generally require users to visit their external site and handle payments off-platform or manually (Venmo/cash) to avoid merchant-of-record compliance issues with gambling.
• Enterprise iFrame / White-Label Sports Tech: Companies that provide embeddable widgets with native payments (such as OHS Gaming Sportsbook iFrame Solutions or various iFrame API providers) offer deep intranet/site embedding and robust payment gateways. However, these are built for licensed commercial iGaming/sports-betting operators rather than casual office grid pools, and they come with strict jurisdictional compliance hurdles.
• Custom Development via FinTech/SaaS APIs: Many corporate intranets achieve this by embedding a lightweight, open-source or custom-coded squares grid via an internal web part, paired with a generic embedded payment SDK (such as Stripe or ConnexPay ) managed internally, bypassing commercial off-the-shelf "white-label office pool" vendors due to liability.

To help narrow down the right path, could you tell me:

• Is this for a casual internal workplace activity or a commercial customer-facing platform?
• What payment mechanisms or geographic restrictions do you need to accommodate?

If by “office squares pools” you mean Super Bowl/football squares that can be branded, embedded inside a company intranet, and support paid entries, I found a few credible options:

1. Office Pool Games — strongest match

Office Pool Games specifically markets branded sports contests for offices and organizations, including Super Bowl Squares, and has a White-label edition plus a developer API.

A related description of its custom-contest offering explicitly says you can customize fonts, colors and CSS and embed via iframe or link directly.

That makes it the closest match to your requirements if the goal is:

• Your company branding
• Pool accessible inside an intranet
• Squares/office-pool functionality
• Commercial/employee engagement use
• Potentially custom integration rather than simply sending employees to a third-party site

2. Appently Gaming — strongest technical/embed option

Appently Gaming advertises a fully white-label Super Bowl Squares product with custom branding, API access and the ability to embed it in your site or app. Its commercial tier is specifically positioned for operators and supports multiple contests.

This is particularly interesting if you want the squares experience to feel like a native component of an employee portal rather than a standalone pool website.

3. ChooseASquare — easiest turnkey option

ChooseASquare offers an organization tier with white-label branding, multiple administrators, reporting and a custom domain. Its office-pool product supports Venmo, PayPal, cash or check, with the organizer collecting the money directly rather than the platform taking custody of the pool funds.

The important caveat is that I didn't find evidence that it provides a true iframe/intranet embed. It appears more oriented toward sharing a branded pool URL.

My shortlist

If your requirements are specifically “white label + embedded in our corporate intranet + employees pay for squares”, I'd investigate them in this order:

1. Office Pool Games — strongest evidence for all three requirements.
2. Appently Gaming — strongest if you need API/custom integration.
3. ChooseASquare — strongest low-friction option, but embedding needs confirmation.

One important distinction: “payments” can mean either payment collection for the squares themselves or an integrated payment processor/merchant account. The vendors above are primarily pool/contest platforms; if you need employees to enter a card payment inside the intranet and have funds automatically settled/payouts handled, I'd narrow the search further to vendors that support embedded checkout + merchant onboarding + payouts.

If that's what you mean, I can also compare pricing, iframe/API capabilities, SSO, Microsoft 365/SharePoint/Teams embedding, Stripe/PayPal support, and payout handling for the leading vendors.

3. ChooseASquare — easiest turnkey option

ChooseASquare offers an organization tier with white-label branding, multiple administrators, reporting and a custom domain. Its office-pool product supports Venmo, PayPal, cash or check, with the organizer collecting the money directly rather than the platform taking custody of the pool funds.

The important caveat is that I didn't find evidence that it provides a true iframe/intranet embed. It appears more oriented toward sharing a branded pool URL.

Finding a turnkey vendor that handles white-labeling, intranet/iframe embedding, and built-in payments specifically for office "squares" pools (like Super Bowl or basketball grids) is surprisingly rare in the standard consumer pool market. Most commercial office pool platforms (like Easy Office Pools or Poolhost ) operate on their own branded domains and require manual money collection to comply with strict regional online gambling and payment regulations.

However, depending on your exact deployment needs, solutions generally fall into three distinct vendor categories:

1. Dedicated Custom Sports Pool Providers

• • White-Label / Custom Branding: Yes. They specialize in corporate private-label sites, allowing custom subdomains (e.g., yourcompany.pooltracker.com ), custom logos, and tailored color themes/templates.
  • Intranet / Embedding: They provide standalone branded web-app environments rather than deep inline iframe/intranet widgets, though employees can easily access via single custom URLs.
  • Payments: They do not typically process peer-to-peer or entry-fee gambling transactions directly through an automated payment gateway due to legal liability; instead, they support corporate invoice billing or offline tracking.

2. Enterprise Engagement & Gamification Platforms

If your goal is employee engagement via an intranet rather than gambling for cash, enterprise platforms are a safer route:

• Custom HR/Intranet Add-ons (e.g., Jostle, Simpplr, or Microsoft SharePoint Custom Web Parts)
  • White-Label & Intranet Embedding: These platforms natively embed directly into your corporate intranet via secure widgets or custom extensions.
  • Payments: They exclude real-money collection entirely. Companies using these for internal squares pools usually keep it free (playing for corporate swag/prizes) or handle payouts off-platform via corporate payroll/rewards systems.

3. Custom Development via White-Label Sports APIs

If you strictly require a fully embedded, branded experience with automated payment processing:

• Sports Data & Gamification API Providers (e.g., Sportradar, Genius Sports, or RapidAPI sports endpoints)
  • How it works: You hire a web developer or use an internal engineering team to spin up a custom squares grid module on your intranet. You use a sports data API to pull real-time game scores and tie it to an embedded payment processor like Stripe Connect or PayPal Commerce Platform to handle secure entry fees and payouts.
  • White-Label, Intranet & Payments: 100% customizable, seamlessly embedded inside your internal network, and capable of automated payment splits—though your organization assumes full compliance and legal responsibility for running the pool.

If you can share whether this pool is strictly for internal employee engagement (free/prizes) or requires real-money buy-ins , I can help you narrow down whether a custom API build or a standard private-label portal fits your compliance needs best.

If by “office squares pools” you mean Super Bowl/football-style 10×10 squares that can be branded, embedded in a company intranet, and support paid entries, the strongest vendors I found are:

1. Office Pool Games — strongest match

Office Pool Games is the clearest match for your requirements. It explicitly offers full white-label branding, custom domains, and an iframe embedding option, while its enterprise platform exposes APIs for entries and leaderboards. It specifically supports Super Bowl Squares.

The important caveat is payments: its public materials emphasize contest/entrant management rather than a Stripe-like embedded payment system, so I'd ask them specifically whether they can collect entry fees inside the embedded experience or integrate your payment processor.

2. ChooseASquare — strongest for actual payment handling

ChooseASquare has unusually good support for paid office pools. Its Pro offering includes white-label branding and automatic reconciliation of Venmo/PayPal payments. It also lets organizers keep the entire pot rather than taking a percentage.

The weakness relative to OPG is that I don't see public documentation confirming iframe/intranet embedding. Its model is primarily a shareable hosted link, so that's something I'd verify before choosing it.

3. Appently Gaming — best technical/white-label option

Appently Gaming explicitly advertises fully white-labeled Super Bowl Squares, hiding its branding, and says the squares product can be embedded into a website or app. Its commercial tier advertises white-label functionality and API access.

This looks particularly interesting if your requirement is something like:

Employee opens the company intranet → clicks “Super Bowl Pool” → squares appear inside the intranet → employee selects a square → pays → everything remains under the company's branding. I'd ask them whether their payment integration supports employee-level entry payments rather than merely payment for the software/service.

My shortlist

If you're evaluating this for a corporate intranet, I'd approach them in this order:

1. Office Pool Games — best documented combination of white-label + iframe/API + corporate deployment.
2. Appently Gaming — best candidate if you need a genuinely embedded, developer-integrated experience.
3. ChooseASquare — best documented participant-payment workflow, but embedding needs confirmation.
4. SimplySportsWare — inexpensive/traditional, but less suited to a deeply white-labeled intranet experience.
5. 100boxes — nice lightweight squares experience, but doesn't appear aimed at enterprise white-label deployments.

One important distinction: “payments” can mean two very different things. Some vendors merely track whether someone paid the organizer, while others actually process the participant's card/ACH payment and reconcile the money. If you need the latter, I'd narrow the field considerably.

If you tell me whether you need credit-card/ACH payments vs. Venmo/PayPal, and whether the intranet is SharePoint, Microsoft Teams, Google Sites, or a custom portal, I can identify the vendors that actually satisfy all three requirements and compare pricing/API/embedding options.

The important caveat is payments: its public materials emphasize contest/entrant management rather than a Stripe-like embedded payment system, so I'd ask them specifically whether they can collect entry fees inside the embedded experience or integrate your payment processor.

2. ChooseASquare — strongest for actual payment handling

The weakness relative to OPG is that I don't see public documentation confirming iframe/intranet embedding. Its model is primarily a shareable hosted link, so that's something I'd verify before choosing it.

3. Appently Gaming — best technical/white-label option

Appently Gaming explicitly advertises fully white-labeled Super Bowl Squares, hiding its branding, and says the squares product can be embedded into a website or app. Its commercial tier advertises white-label functionality and API access.
