Software solution
Square App Marketplace
Square App Marketplace is Square’s U.S. directory for discovering partner applications that connect to a Square account. It can help a bakery sync online orders, a salon connect scheduling, a retailer link ecommerce and inventory, or a contractor organize payments and back-office work without replacing Square at checkout.
Built for your day-to-day
The catalog includes free tiers, trials, and paid partner plans, so the Marketplace is a discovery and connection layer rather than one bundled software subscription. Each listing controls its own features and price. Confirm the app’s U.S. availability, Square product compatibility, data permissions, support terms, and cancellation policy before connecting it to live operations.
Key capabilities
Browse categories and curated collections for areas such as ecommerce, marketing, delivery, scheduling, inventory, and point of sale instead of assembling an integration stack from unverified links.
Marketplace apps are designed to connect to the Square account a seller already relies on, allowing selected data and workflows to sync between Square and the partner service.
The U.S. catalog includes partner listings marked Free, Free plan available, and free trials. Those offers belong to the individual partner and should not be treated as a universal Marketplace benefit.
A restaurant can evaluate order and reservation tools, a shop can compare ecommerce and shipping connections, and a service business can look for scheduling or customer-management integrations in one U.S.-focused catalog.
Square publishes a Terminal collection for apps that wirelessly sync to Square Terminal. Device compatibility is therefore app- and collection-specific, not an automatic property of every Marketplace listing.
Explore the details
A merchant starts with a Square account and then authorizes an individual partner app. For developers, Square says Marketplace listing requires approval as a Square app partner plus technical and quality compliance; apps must use Square APIs and OAuth to connect to a seller account, and submissions go through Square review. That publisher process is not a promise that every app has the same capabilities or support model.
There is no Marketplace-wide monthly subscription or hardware purchase price. Partner listings set their own pricing, including free plans, trials, starting prices, and pricing may vary. A connected app does not remove Square’s own plan or payment-processing charges. Square’s U.S. pricing page currently shows Square Free at $0/month, with published processing rates that depend on plan and payment method; use the live Square pricing page and the individual app listing for the transaction and subscription terms that apply.
The Marketplace is not a single all-in-one app and it does not guarantee that an app works with every Square product, country, device, or workflow. Some apps are built for Square Online, some for particular POS or payment connections, and some require a particular partner plan. Review the listing’s supported country, integration scope, permissions, required Square product, data-sync direction, offline behavior, and partner support terms before deployment. The Terminal collection confirms that hardware support must be checked at the app level.
Plan details
Square App Marketplace has no single Marketplace subscription price. Partner apps set their own plan prices and may offer free tiers, trials, starting prices, or custom pricing. Square account, software-plan, payment-processing, and hardware costs remain separate and depend on the selected Square products and partner app.
Set and charged under the individual partner’s terms; verify the current U.S. listing before purchase.
Square’s published U.S. plan price; this is a Square plan, not a Marketplace-wide app price.
Square U.S. pricing page; applies to tap, dip, or swipe on the published Free plan and is separate from any partner fee.
Square U.S. pricing page; payment-method and plan qualification applies, and partner charges may be additional.
Square App Marketplace is a catalog and integration channel, not one bundled software product; capabilities, support, uptime, data handling, and cancellation terms vary by partner.
Partner prices and offers can change. A free Marketplace listing or trial does not establish that all features, usage, support, or future renewals are free.
Square plan prices and processing fees are published separately from partner charges and can vary by plan, payment method, and eligibility.
Hardware support is not universal. The official Terminal collection demonstrates device-specific compatibility; check the individual app listing for supported Square hardware and workflows.
The record uses official Square U.S. pages plus Square developer documentation. No image is marked approved because no marketing-use license evidence was established.
Questions
Accessing the Marketplace is not presented as a single paid subscription, and some partner listings are free or offer free tiers. Individual apps may charge a monthly fee, usage fee, or custom price, and Square’s own plan and payment-processing charges remain separate.
No. Compatibility is app-specific. Square publishes a collection for apps that work with Square Terminal, but a Marketplace listing should be checked for the exact Square product, device, country, permissions, and workflow you need.
Start with a Square account, review the partner listing and its terms, confirm U.S. availability and required Square products, and authorize only the permissions needed for the intended workflow. The partner may also require a separate account or paid plan.
