If you mean subscription-management systems that can use Square as the payment processor, there are two broad approaches:
Square Subscriptions itself — Square has native recurring billing, including weekly/monthly/quarterly/annual plans, trials, pauses, billing anchors, invoices, and hosted checkout links.
Custom subscription software via Square's APIs — A membership, SaaS, booking, CRM, or ecommerce system can create and manage subscriptions through Square's Subscriptions API, with webhooks for subscription events.
-hosted checkout — Third-party systems can send customers to a -hosted payment page for a specific subscription plan using the Checkout API.
If you mean third-party systems that can use Square as the payment processor for recurring/subscription billing, the landscape is somewhat narrower than with Stripe.
Square App Marketplace integrations — Square supports third-party applications through its App Marketplace, although the exact subscription/billing capabilities depend on each app.
If you're looking for specific platforms—for example MemberPress, WooCommerce, Kajabi, Mindbody, Chargebee, Recurly, Stripe, or a CRM/membership system—tell me what type of business/system you're integrating, and I can identify which ones currently support Square specifically for recurring subscription billing, including the integration method and limitations.
If you are looking to run recurring revenue or subscription models using Square as your processor, you can use Square’s native Square Subscriptions and Recurring Invoices tools, or connect specialized third-party platforms from the Square App Marketplace.
Top systems and software that integrate with Square for subscription billing include:
PayWhirl — A leading recurring billing and subscription app built specifically to integrate with Square Online and websites. It allows you to embed subscription widgets directly on product pages, manage customer billing portals, automate failed payment retries, and sync orders straight into your Square dashboard.
Submatic — Designed for businesses selling memberships, recurring packages, and structured subscriptions with a robust management feature set and native Square integration.
Billforward — Suited for more complex, enterprise-grade, or usage-based subscription billing workflows that need to hook directly into Square's payment ecosystem.
Chargebee — A heavyweight subscription management and recurring billing platform that natively supports Square alongside other gateways for comprehensive subscriber lifecycle management.
Maxio — Advanced subscription billing and financial analytics platform that integrates with Square to streamline revenue operations and recurring billing tracking for B2B/SaaS businesses.
If you'd like, let me know:
What type of business or product you are running (e.g., eCommerce, SaaS, local services/memberships)
Whether you need a customer self-service portal
I can help you recommend the best integration for your exact workflow.
Several specialized third-party platforms and native APIs integrate with Square to handle advanced subscription billing and recurring revenue management.
While Square offers its own native Square Subscriptions API and recurring invoice options for basic automated billing, growing merchants often pair Square with dedicated subscription management platforms for advanced tiers, customer portals, and analytics.
Third-Party Systems and Apps that Integrate with Square
System
Primary Use Case
Key Integration Features
PayWhirl
E-commerce & membership recurring billing
Embeds directly with Square Online, customer billing portals, automated failed payment retries, and customizable billing schedules.
Automates recurring invoicing, white-labeled customer portals, and in-store subscription signups paired with POS hardware.
Native Developer Options
Square Subscriptions API : If you are building a custom software solution, developers can use Square's native Subscriptions API to programmatically implement fixed recurring billing and card-on-file charges directly into custom applications.
If you share your specific business model (e.g., e-commerce, in-person memberships, B2B SaaS) and what features you need (like customer portals or custom billing cycles), I can recommend the best integration for your setup.
If you mean subscription-billing/recurring-payment systems that can work with Square, there are two broad approaches:
Square Subscriptions itself — Square has native recurring billing, including weekly, monthly, quarterly, and annual plans, trials, pauses/resumes, checkout links, and automatic card charging.
Custom applications via Square APIs — Square exposes a Subscriptions API, Catalog API, Customers API, Invoices API, Payments API, and webhooks, so a custom CRM, membership system, SaaS app, or billing front end can manage Square subscriptions programmatically.
Subscription platforms such as Chargebee, Recurly, Paddle, and Stripe Billing — these are established subscription-billing systems, but they generally aren't interchangeable with Square as a payment processor. Their documented gateway integrations prominently support processors such as Stripe and other gateways rather than Square. For example, Recurly documents Stripe as a payment gateway, and Chargebee documents Stripe integration.
So if your requirement is specifically “I want a third-party subscription system to manage subscriptions while Square processes the recurring payments,” the compatibility list is much narrower than the general list of subscription-billing platforms.
If you tell me what you're integrating—e.g. membership software, SaaS, website/e-commerce, CRM, accounting, or a custom app—I can identify the systems that actually support Square as the payment processor and compare them.
Square integrates with several third-party applications and tools designed specifically for recurring billing, memberships, and subscription management. While Square natively supports recurring invoices (where an invoice is automatically sent and charged on a repeating schedule), full subscription e-commerce and advanced billing logic are typically handled via extensions and partner apps found in the Square App Marketplace.
Top systems and apps that integrate with Square for subscription billing include:
PayWhirl — A robust recurring billing and subscription app that integrates deeply with Square. It lets customers manage their own subscription plans, securely saves payment methods on file, automates recurring charges, and embeds directly into web checkouts without redirecting users off-site.
Subport — Designed closely for Square sellers (especially in retail, cafes, services, and medspas), Subport enables tiered subscription programs, membership models, and automated recurring billing while tying directly into your existing Square catalog, customer lists, and reporting tools.
Billforward — A comprehensive subscription management platform handling complex scenarios like usage-based billing, volume pricing, free trials, and custom recurring intervals (from hourly/daily to monthly billing) linked directly to in-person and online Square transactions.
Subscriptions Cloud — Allows merchants to turn physical inventory or products into routine recurring orders, supporting mixed carts where customers can bundle one-time purchases and active subscriptions in a single checkout session.
Third-Party Connectors (e.g., Skyvia / Chargebee) — If you use enterprise-tier revenue management platforms like Chargebee , third-party integration pipeline services can sync Square payment processing data with advanced subscription infrastructure.
If you'd like to narrow this down, let me know:
Are you looking for online e-commerce subscriptions or in-person memberships (like a gym or service)?
Do you need usage-based billing or a fixed recurring fee?
Square Subscriptions — Square has its own native subscription-billing system. You can create plans, recurring billing schedules, trials, pauses/resumes, and subscription checkout links directly in Square. It is also exposed through Square's Subscriptions API for custom applications.
Custom software via Square APIs — A CRM, membership platform, SaaS application, or custom billing system can integrate directly with Square's Subscriptions, Customers, Orders, Invoices, Payments, and Cards APIs.
Square App Marketplace integrations — Square supports partner applications for extending its commerce and payment capabilities, although compatibility with Square as the recurring-billing processor varies by application.
Important distinction
Platforms such as Chargebee and Recurly are subscription-management/billing platforms, but their documented payment-gateway integrations prominently support processors such as Stripe, Braintree, PayPal, etc.; I would not assume they can use Square as their payment gateway without a specific Square connector.
Square's native system can charge a card on file at the beginning of each billing period or generate an invoice if there isn't a card on file. ACH isn't supported for recurring subscriptions through the Square Subscriptions API.
If you're choosing a system for a particular use case—e.g. SaaS, memberships, gyms, courses, donations, or recurring services—tell me which one, and I can identify the Square-compatible systems and compare their billing capabilities.
If you mean software/platforms that can use Square as the payment processor for recurring subscription billing, there are two broad categories:
Square’s native subscription stack — Square Subscriptions + Catalog + Customers + Orders + Invoices/Payments APIs. This is the most direct option for recurring billing. Square supports recurring weekly, monthly, biweekly, quarterly, semiannual, and annual billing, plus trials, pauses, and subscription changes.
Custom applications — Any application can integrate with Square’s Subscriptions API to create and manage plans, enroll customers, update/cancel subscriptions, and receive webhook events.
Website/checkout systems — Square’s Checkout API/Payment Links can sell a Square subscription plan through a hosted checkout page, with subsequent recurring charges handled by Square.
CRM/automation/integration platforms — Tools can connect to Square through its APIs/webhooks, but whether a particular platform offers native Square subscription-billing support varies considerably.
If you're asking for specific third-party systems (e.g. Shopify, WooCommerce, Wix, Mindbody, Memberstack, Chargebee, Stripe Billing alternatives, accounting/CRM systems, etc.), tell me what type of business/system you're integrating with and I can give you a current list of the ones that actually support Square recurring billing, rather than just generic Square payment integrations.
If you are looking to expand beyond Square’s native recurring invoices, several third-party applications and platforms integrate directly with Square to handle advanced subscription billing, membership management, and recurring revenue.
The top options available via the Square App Marketplace or direct API connections include:
PayWhirl : A robust and seamless subscription app built for Square. It allows you to sell subscriptions or payment plans on any schedule, manage customer payment methods on file, handle automated billing retries for failed payments, and provide a secure self-service portal for customers to manage their own plans.
Subport : Designed specifically for Square sellers (such as cafes, retail, and service providers) wanting to turn occasional buyers into long-term subscribers. It integrates directly with your existing Square items, reporting tools, and customer database to automate recurring charges and offer custom loyalty perks.
Billforward : A versatile recurring billing platform that syncs with Square to support complex billing models. It handles everything from flexible billing cycles (minutes, days, months) and free trials to usage- and volume-based billing for memberships and services.
Native Square Invoices : If your needs are straightforward, you can use Square's built-in tool to set up a recurring series directly from your Square Dashboard. It allows you to automatically charge a card or bank account on file at regular intervals (weekly, monthly, etc.) without needing a third-party plugin.
If you can share what type of business you run (e.g., e-commerce, a gym/membership site, or B2B services) and how complex your billing model is (fixed vs. usage-based), I can help you choose the best integration.
Square supports subscription billing and recurring payments through its native tools (like Square Invoices or the built-in Square Subscriptions feature), but you can also connect third-party apps depending on your specific industry and checkout setup.
The top third-party systems and apps that integrate with Square for subscription and recurring billing include:
PayWhirl : Allows you to set up recurring billing and subscription options that integrate tightly with Square checkouts and websites, enabling customers to manage their own subscription portals.
Billforward : Built for complex billing scenarios (tiered pricing, usage-based, free trials, and volume pricing) across industries like gyms, insurance, and retail.
Subport : Great for local businesses, cafes, and service providers (like MedSpas) wanting to offer credit or unlimited-style membership programs directly linked with Square.
Subscriptions Cloud : Enables everyday product or box subscriptions on daily, weekly, or monthly cadences alongside mixed cart/one-time checkouts.
You can browse and install these options directly through the Square App Marketplace.
If you can share what type of business you run (e.g., e-commerce, SaaS, a gym, or a local service) and how complex your billing needs are (e.g., usage-based vs. flat monthly fee), I can help you choose the best fit.
Custom applications — Square’s Subscriptions API lets a SaaS, membership system, website, or custom app create and manage subscriptions programmatically. It works alongside the Catalog, Orders, Customers, Invoices, and Payments APIs.
Custom checkout systems — Square's Checkout API can generate a Square-hosted checkout page tied to a subscription plan, so customers can sign up for recurring payments without you building the payment form yourself.
Scheduling/appointment platforms — For example, Acuity Scheduling supports Square for payments and also has subscription-related functionality.
Square Online — Physical or digital items can be configured for recurring subscriptions through Square Online.
If by “systems” you mean specific third-party subscription platforms that integrate with Square—such as Stripe Billing alternatives, membership-management systems, SaaS billing platforms, gym/fitness software, or accounting systems—I can give you a current list and compare Square compatibility, recurring billing, proration, failed-payment handling, coupons, trials, and webhooks.
