Payment processors with integrated merchant accounts

The processors and payment platforms that meet this criteria are aggregated payment service providers (PSPs) or all-in-one merchant platforms . Instead of forcing you to apply for, underwrite, and manage a separate dedicated merchant account through a traditional acquiring bank, they place you under their master merchant umbrella instantly upon sign-up.knowledge.antom.com

The top platforms supporting payment links, invoices, recurring subscriptions, hosted checkouts, and robust developer APIs out-of-the-box without a separate merchant account include:

• • Stripe : The gold standard for this exact combination. It requires no separate merchant account setup, features powerful APIs, native recurring billing/subscriptions, automated and customizable invoicing, no-code Payment Links, and fully hosted checkout pages (Stripe Checkout).knowledge.antom.com
• • PayPal (PayPal Checkout / Braintree) : PayPal's ecosystem allows you to accept payments via APIs, hosted solutions, and recurring billing. While Braintree handles deeper developer integrations and custom hosted/API environments under a unified PayPal master account, standard PayPal business tools provide ready-to-use invoicing, payment buttons, and links without an independent bank merchant account.
• • Square : Best known for omnichannel, Square provides robust APIs, robust subscription/recurring invoicing tools, email invoices, and custom checkout links/hosted options, operating entirely under an aggregated account structure rather than a standalone dedicated merchant ID.
• • Adyen (for Platforms / Marketplaces) or Checkout.com : While traditionally enterprise-focused, they offer streamlined onboarding options and unified APIs covering hosted checkouts, recurring subscriptions, and links, though Stripe remains far more self-serve for instant aggregated setups.
• • Paddle / Lemon Squeezy : Operating as Merchant of Record (MoR) models rather than just standard processors, they take it a step further—handling global tax compliance, subscriptions, hosted checkouts, invoices, and APIs while completely absorbing the merchant of record burden so you don't even need a traditional business merchant setup.

If you'd like, let me know:

• Your expected monthly volume or business model (SaaS, e-commerce, freelance services)
• What geographies or currencies you plan to support

I can help narrow down which of these options fits your technical stack and fee structure best.

If you want a payment processor that supports payment links, invoices, subscriptions, hosted checkout, and APIs without requiring you to set up a separate traditional merchant account, there are two main categories to consider:

• All-in-one payment platforms: provide payment processing, billing tools, hosted checkout, and APIs under one business account.
• Merchant of record (MoR) platforms: handle the sale as the legal seller, including payment processing and often sales tax/VAT compliance, so you don't need your own traditional merchant account.

The key distinction is whether you simply want one provider account for everything or want the provider to handle merchant-of-record responsibilities too.

Best processors to evaluate

Compared against your five requirements, using official documentation available as of October 2026.

1. Paddle

(Best for SaaS and subscriptions)

Merchant of record with hosted checkout, subscription billing, invoices, payment links and APIs. Paddle handles payment processing and tax responsibilities as the seller of record.developer.paddle.com+2

• 

2. Lemon Squeezy

(Best for simple digital-product sales)

Merchant of record designed for software, digital downloads and recurring subscriptions. Offers checkout links, a customer portal, subscription management and APIs without requiring you to manage your own merchant account.docs.lemonsqueezy.com+2

• 

3. Stripe

Strong all-in-one option for general businesses. Supports payment links, recurring subscriptions, invoicing, hosted Checkout and extensive APIs. You use a Stripe account rather than opening a separate traditional merchant account, but Stripe is generally your payment processor, not your merchant of record.stripe.com+2

• 

4. Square

Offers hosted payment links, recurring subscription checkout, invoices and APIs under a Square account. Especially worth considering for service businesses and businesses combining in-person and online payments.developer.squareup.com+1

Website: squareup.com ·Developer docs

---

• 

5. PayPal

Supports hosted payment links, invoicing and APIs. Recurring payments are available through its broader products, but the feature set is split across different services. Requires a PayPal Business account, so it is not a completely account-free option.developer.paypal.com+2

Website: paypal.com/business ·Developer docs

Feature comparison

Invoice capabilities differ: some platforms focus on formal invoices with payment collection, while others primarily generate receipts or billing records. Paddle supports sales-assisted invoices and invoice payment links; Stripe offers a full invoicing product.

Which one should you choose?

• Want no separate merchant account and minimal tax/compliance administration? Start with Paddle or Lemon Squeezy.
• Want the most flexible general-purpose payment API? Start with Stripe.
• Run a local service business or accept in-person payments too? Consider Square.
• Want PayPal as a familiar customer payment option? Consider PayPal, either alone or alongside another processor.

One important caveat: none of these guarantees approval for every country or business type, and all may require identity verification and business onboarding. “No separate merchant account” does not mean “no account or underwriting.”

What kind of business are you building? I can narrow this to the strongest fit and compare fees and limitations.

Compare merchant-of-record platforms Compare fees and API features

Yes. There are several payment gateways and payment processors that combine a merchant account or merchant processing relationship with developer APIs, recurring subscriptions, hosted checkout, payment links, and invoicing.

The key distinction is what you mean by “built-in merchant account.” If you want to sign up with one provider and have that provider handle payment processing and settlement—without separately sourcing a merchant account and gateway—there are good options. If you need a traditional, dedicated merchant account with direct acquiring, that narrows the list.

Best candidates to evaluate

• 

1. Stripe — Best overall for API-first businesses

(Best developer experience)

Stripe provides payment processing through its own merchant onboarding model, with no separate merchant account provider required for standard accounts.

• APIs: Payments, customers, subscriptions, invoices, and webhooks.
• Subscriptions: Stripe Billing supports recurring payments, trials, and usage-based billing.
• Hosted checkout: Stripe Checkout supports hosted and embedded payment flows.
• Payment links: Supports one-time and recurring payments.
• Invoicing: Stripe Invoicing supports billing and online payment collection.

Stripe documents these capabilities across its Checkout and billing products.stripe.com

Best for SaaS, digital products, marketplaces, and custom applications. Note that Stripe generally uses an aggregated payment-processing model rather than giving each merchant a traditional dedicated merchant account.

---

• 

2. Square — Best all-in-one business platform

Square combines payment processing, online checkout, invoices, and recurring billing under one business account.

• APIs: Payments, Checkout, Customers, Invoices, and Subscriptions.
• Subscriptions: Subscription plans and recurring billing through its API.
• Hosted checkout: Create Square-hosted checkout pages through the Checkout API.
• Payment links: Create checkout links programmatically.
• Invoicing: Digital and recurring invoices, reminders, and payment tracking.

Official references: Square Checkout API, Subscriptions API, and Invoices.developer.squareup.com+2

Best for small and midsize businesses, services, retail, and companies that also accept in-person payments. Verify API and subscription feature availability for your country and business type.

---

• 

3. PayPal — Best for payment flexibility and reach

PayPal combines its payment processing ecosystem with APIs for online checkout, recurring payments, payment links, and invoicing.

• APIs: REST APIs for payments, subscriptions, and invoicing.
• Subscriptions: Recurring billing integrations.
• Hosted checkout: PayPal-hosted payment experiences.
• Payment links: Shareable links with a hosted checkout page and API support.
• Invoicing: Itemized invoices, payment links, and reminders.

Official references: Developer platform, Payment Links, and Invoicing API.developer.paypal.com+2

Best for businesses that want PayPal alongside cards and other eligible payment methods. Check the exact subscription and payment-method capabilities for your intended integration.

---

• 

4. Authorize.net — Best for traditional merchant-account setups

Authorize.net offers gateway APIs, hosted payment forms, recurring billing, and invoicing. It is especially relevant if you want a more traditional processing arrangement.

• APIs: Payment processing and automated recurring billing.
• Subscriptions: Automated recurring billing through the ARB API.
• Hosted checkout: Secure hosted payment forms.
• Payment links and invoices: Invoice-based payment collection and hosted payment pages.
• Merchant accounts: Processing arrangements depend on the plan and provider; confirm whether your selected offer includes an underlying merchant account or requires a separate processor.

Official references: Payment processing, Recurring payments, and Invoicing.www.authorize.net+2

Best for established businesses that prioritize traditional merchant processing, recurring payments, and integration with existing systems.

• 

5. RapidCents — Worth investigating for a unified merchant account

RapidCents explicitly describes its products as operating on one merchant account, including online processing, hosted checkout, payment links, invoicing, and recurring billing.

• APIs: Payment integrations.
• Subscriptions: Recurring billing.
• Hosted checkout and payment links: Offered as part of its processing platform.
• Invoicing: Integrated into its payment tools.
• Merchant account: Advertised as a shared account across payment channels.

See RapidCents products.rapidcents.com

Worth evaluating if a unified merchant account is a firm requirement. Confirm API coverage, supported countries, underwriting, pricing, and contract terms directly with the provider.

Feature comparison

This is a high-level comparison of documented product capabilities, not a guarantee that every feature is included in every plan or region.

*Integrated processing means the provider handles merchant onboarding and payment processing without requiring you to independently assemble a separate gateway and processor. It does not necessarily mean a dedicated merchant account in your business's name.

My recommendation

• Choose Stripe if your priority is a robust API, subscriptions, hosted checkout, and straightforward integration into a web application.
• Choose Square if you also need operational business tools and in-person payments.
• Choose PayPal if you value PayPal as a payment method and want payment links and invoicing in the same ecosystem.
• Investigate Authorize.net or RapidCents if the traditional merchant-account relationship is especially important.

One important consideration: a gateway is not necessarily a merchant account provider. If you specifically need your business to have its own merchant ID and a direct acquiring or processing relationship, get that confirmed in writing before signing up.

One question that would help narrow this down

When you say “built-in merchant account,” do you mean:

1. What kind of merchant account do you need?

A single provider account, with processing and settlement included (Stripe-style)

A dedicated traditional merchant account in my business's name, with its own merchant ID

Either model is fine, as long as all five features are supported

---

2. Where is your business registered?

United States

United Kingdom or European Union

Other country

---

3. What is your business model?

SaaS or subscription software

E-commerce or physical products

Professional services or invoicing

Marketplace or payment platform

High-risk or specialized industry

[Find the best-fit providers]

Yes, several prominent payment service providers (PSPs) and payment gateways operate as all-in-one platforms with built-in merchant accounts. This means you do not need to apply for a separate, traditional merchant account with an acquiring bank; your signup immediately provisions a sub-account under their master merchant umbrella.

The leading platforms that natively support all of these requested features (APIs, subscriptions/recurring billing, hosted checkout pages, no-code payment links, and invoicing) include:

• Stripe : Widely considered the gold standard for developer-first, all-in-one setups.
  • APIs : Extremely robust REST APIs and SDKs for custom payment flows.
  • Subscriptions : Advanced recurring billing engine via Stripe Billing supporting usage-based billing, trials, and prorations.
  • Hosted Checkout : Fully hosted, PCI-compliant payment pages (Stripe Checkout).

  • Invoicing : Natively create, customize, and email hosted professional invoices with automated reminders and smart retry logic for failed payments.nerdwallet.com+3

  • APIs : Full REST API suite for backend integration and custom UIs.
  • Subscriptions : Comprehensive subscription management through PayPal Subscriptions or Braintree's recurring billing.
  • Hosted Checkout : Hosted fields and smart payment buttons that adapt to user preferences.

  • Invoicing : A powerful, feature-rich Invoicing API and dashboard tool allowing you to send professional multi-item bills globally.developer.paypal.com+1
• Square : While historically known for physical point-of-sale hardware, Square has heavily expanded its online and developer ecosystem.
  • APIs : Robust APIs for catalog management, online checkouts, and customer data.
  • Subscriptions: Square Invoices and recurring profiles support auto-charge subscription billing.
  • Hosted Checkout : Pre-built checkout flows and e-commerce site integrations.

If you'd like to narrow down which of these fits best, let me know:

• Your expected monthly processing volume or average ticket size
• Whether you need support for international currencies or local payment methods (like iDEAL, SEPA, or Cash App)
• Your primary programming stack or e-commerce builder (e.g., custom code, WordPress, Shopify)
