Which services facilitate subscription sales for point-of-sale systems like Square?

If by “facilitate subscription sales for POS systems like Square” you mean services that let a physical business sell recurring memberships/subscriptions and charge customers automatically, there are several categories:

• Square Subscriptions — built directly into Square. Supports recurring weekly, monthly, quarterly, or annual billing, checkout links, QR codes, trials, pauses, and subscription management.Square+1
• Stripe Billing + Stripe Terminal — particularly useful if you want a more customizable setup. Stripe explicitly supports signing up subscribers at a physical point of sale and storing their payment details for recurring charges.Stripe+1
• Shopify Subscriptions + Shopify POS — lets merchants sell subscription products both online and in-store. Shopify requires its Subscriptions app or a compatible third-party subscription app for POS sales.Shopify Help Center+1
• Recurly — a dedicated subscription-management platform that can sit alongside an existing payment processor, website, and CRM rather than being the POS itself.Shopify
• Chargebee — another dedicated subscription/billing platform, particularly oriented toward more sophisticated recurring-revenue businesses. Shopify currently lists it alongside Stripe Billing, Recurly, and other subscription-management tools.Shopify
• Appstle / Recharge / Bold / Ordergroove / PayWhirl — subscription-focused services, especially common in ecommerce. They are more about subscription management than replacing the POS itself.Shopify

If you're specifically building a POS business

There are really three different models you might be looking for:

1. POS with subscriptions built in — Square, Shopify POS.
2. Payment infrastructure with subscription billing — Stripe Billing + Terminal.
3. Independent subscription-management layer — Recurly, Chargebee, Recharge, etc., connected to a POS/payment processor.

If you're asking because you're looking for a service that can sell subscriptions on behalf of a POS software company—e.g., handling billing, recurring payments, customer signup, failed-payment recovery, etc.—I can also map out the major providers and their APIs/fees for that use case.

Native features and third-party integrations handle subscription sales and recurring billing for point-of-sale systems like Square.

Native Square Tools

• Square Invoices: Allows businesses to set up automated, recurring billing cycles where customer cards are safely saved on file to charge on a scheduled weekly, monthly, or yearly basis.squareup.com
• Square Online: Integrates physical inventory and digital checkout to support recurring item purchases and digital memberships directly through an e-commerce storefront.
• Square Appointments: Manages recurring service bookings, automated client reminders, and card-on-file deposits or membership fees for service-based businesses.

Third-Party & App Marketplace Integrations

• Recharge / Bold Subscriptions: Specialized platforms that integrate with online storefronts tied to your POS to manage advanced recurring delivery or subscription boxes.
• Chargebee / Recurly: Enterprise-grade recurring billing engines that sync customer data and transaction flows with processing ecosystems.
• QuickBooks / Xero: Accounting platforms that sync with Square to track recurring invoice payments and membership revenue.

If you can share what type of business you run (e.g., retail, a fitness studio, or a service-based agency) and whether you need in-person or online subscriptions , I can recommend the exact setup or tool you need.

To facilitate subscription sales and recurring billing for point-of-sale (POS) systems like Square , you can use Square's native tools or leverage dedicated third-party apps integrated directly through the ecosystem.

1. Native Square Tools

• Square Subscriptions: A built-in feature allowing you to set up recurring billing models, flexible plan durations (weekly, monthly, annual), optional free trials, and manage subscribers right from your dashboard or supported POS devices.squareup.com+1
• Square Online "Subscribe & Save": Enables you to sell single-item physical goods, donations, or services on a recurring basis via your connected Square Online storefront.community.squareup.com
• Square Recurring Invoices: Allows you to schedule and automate recurring payment requests sent directly to a customer's email or phone on a set periodic schedule.squareup.com

2. Third-Party App Integrations (Square App Marketplace)

For more advanced membership tiers, digital passes, or complex billing rules, specialized platform integrations sync directly with Square POS:

• Submatic: Designed for businesses like coffee shops, wine clubs, and salons to sell memberships, multi-visit packages, and recurring passes directly in-store via Square POS or online.
• Subport: Tailored for hospitality, retail, and service businesses to manage tiered subscription programs, credits, and "unlimited" usage models synced across multiple Square locations.
• PayWhirl: Connects recurring billing and customer-managed subscription portals directly to your checkout workflow without forcing users off-site.
• Billforward: Built for heavier enterprise needs requiring complex subscription lifecycle management and automated recurring billing structures.squareup.com+3

If you can share what type of business you run (e.g., retail, a service-based business, or a food/beverage club) and where you plan to sell (in-person at the register vs. online), I can recommend the best option for your workflow.

If you mean services that let a business sell recurring memberships/subscriptions through a POS system like Square, there are several categories:

• Square Subscriptions — Square has a native subscription system. Merchants can create recurring plans, accept recurring card payments, use hosted checkout links/QR codes, and manage pauses, cancellations, and billing cycles.Square+1
• Stripe Billing + Stripe Terminal — Stripe supports recurring subscriptions and also supports enrolling subscribers through in-person POS payments, with payment details tokenized for subsequent recurring charges.Stripe+1
• Subscription-management platforms — Services such as subscription billing/membership platforms can sit on top of a payment processor, handling things like plans, recurring billing, dunning, customer portals, trials, upgrades/downgrades, and entitlements. Stripe Billing is an example of this model.Stripe
• Custom POS integrations — If you're building software for merchants, Square's Subscriptions API lets your application create and manage subscriptions directly in a merchant's Square account. You can combine it with Square's Catalog, Customers, Orders, Checkout, and Payments APIs.Square+1

So, architecturally, you can think of it as:

Customer → POS/checkout → payment processor → subscription/billing engine → recurring charge

For Square specifically, you don't necessarily need a third-party subscription service: Square itself provides the recurring-billing infrastructure and APIs.Square+1

If you're asking because you're building a subscription product that needs to work with Square POS, I can also lay out the main providers that support POS + memberships + recurring billing, including their pricing and APIs.

If you mean services that let a business sell recurring subscriptions/memberships through a POS, there are several categories:

• Square Subscriptions — Square itself has a built-in subscription system. Merchants can create recurring plans, accept card-on-file payments, use checkout links/QR codes, and manage pauses, cancellations, etc.Square+1
• Stripe Billing + Stripe Terminal — Stripe can handle recurring billing while Terminal handles in-person POS payments. Stripe specifically supports signing up subscribers at the point of sale and storing payment credentials for recurring charges.Stripe+1
• Clover Subscriptions / Recurring Payments — Clover has APIs for creating recurring plans and associating customers with subscriptions, including automated recurring charges.Clover Platform Docs+1
• POS-specific membership platforms — There are also third-party systems aimed at gyms, salons, clubs, classes, etc. These typically sit on top of a payment processor/POS and handle membership enrollment, recurring billing, customer management, and sometimes access control.

If you're asking because you want to build a service that sells subscriptions on behalf of merchants using Square-like POS systems, the architecture is a little different. You'd generally look at Square's Subscriptions API, Stripe Billing/Terminal, and Clover's recurring-payment APIs as the underlying payment rails rather than building card-on-file billing yourself. Square, for example, exposes APIs to create, pause, resume, cancel, and change subscriptions.Square+1

If you tell me whether you mean (1) software you can buy for your own business, (2) platforms you could integrate into a product, or (3) companies that sell subscriptions/memberships through POS terminals, I can give you a more targeted list.

To facilitate subscription sales and recurring billing directly for point-of-sale (POS) systems like Square, you can use a mix of built-in native features and specialized third-party apps available in the ecosystem.

1. Built-in Square Features

• Square Invoices (Recurring Series): Allows you to set up automated, recurring card-on-file charges for regular clients. You can configure a recurring schedule (weekly, monthly, annually), save a customer's payment method securely, and automatically charge them on schedule. You can access this via the Square Invoices Support Guide.youtube.com+1
• Square Online Subscriptions: If you sell physical goods, boxes, or digital memberships online through Square, you can attach subscription options directly to items so customers can select recurring delivery frequencies right at checkout.youtube.com+1

2. Third-Party Apps & Integrations (Square App Marketplace)

For advanced membership tiers, tiered club management, usage tracking, or specific retail/service models, specialized integrations connect directly to your POS data:

• Subport: Excellent for cafes, service providers, and clinics looking to offer membership programs, credit-based subscriptions, and "unlimited" usage models that sync and redeem across multiple physical Square locations. More details can be found on the Subport Subscription Management App Page.squareup.com
• Submatic: Designed specifically for businesses handling recurring memberships, packages, and recurring customer boxes. Check out the options on the Square Invoicing & Services Marketplace.squareup.com
• Industry-Specific Software: Apps like VIP Shop Management (for automotive recurring service plans) integrate smoothly to handle niche recurring billing logic tied to physical POS workflows.

If you'd like, let me know:

• What type of business you run (e.g., retail, food/beverage, professional services, fitness)
• Whether you need subscriptions sold in-person at the register or online

I can give you a more tailored recommendation on whether the native tools or a specific marketplace app fits best.

If by “services” you mean software/payment platforms that let a merchant sell recurring subscriptions or memberships through a POS, there are several categories:

• Square Subscriptions — Native to Square. Merchants can create recurring plans, offer trials, choose weekly/monthly/annual billing, generate checkout links/QR codes, and manage subscribers. Square also exposes a Subscriptions API for developers.Square+1
• Stripe Billing + Stripe Terminal — A strong option if you want a more sophisticated subscription engine. Stripe supports signing up customers for recurring plans directly through POS payments and tokenizing their payment details for subsequent charges.Stripe+1
• Shopify Subscriptions + Shopify POS — Lets merchants sell subscription products in-store as well as online. Shopify also supports third-party subscription apps that integrate with POS.Shopify Help Center+1
• Mindbody — Particularly relevant to gyms, fitness studios, salons, and wellness businesses. Its integrated payments support recurring membership charges and card-on-file billing.Mindbody+1
• Toast + subscription/loyalty partners — For restaurants, Toast has partners such as Hang that allow customers to sign up for paid memberships directly at the POS with automated recurring billing.Toast POS

If you're looking to build a service on top of Square

The interesting distinction is between:

1. Subscription billing infrastructure — Stripe Billing, Square Subscriptions, etc.
2. Membership/subscription management software — handles plans, benefits, customer status, cancellations, renewals, etc.
3. POS integrations — lets staff sell the subscription during an in-person checkout.
4. Payment processing/tokenization — securely stores the payment method and handles recurring charges.

For a Square-based product, you generally don't need to become the payment processor yourself. Square's APIs can create and manage subscription plans and recurring charges while Square handles the underlying payment infrastructure.Square+1

If you're asking because you're considering building a SaaS that enables businesses to sell memberships/subscriptions through Square, I can also map out the existing competitors and the APIs/architecture you'd need.
