The conversations that bring buyers here.

No Combined Inventory View

We have 6 store locations on Square and no way to see combined inventory across all of them.

Basic Loyalty Tool

Square's loyalty tool is fine but it doesn't do what we actually want for our regulars.

Generic Terminal Screen

We want a self-order kiosk that matches our brand, not the generic Square terminal screen.

No In-House Team

We're a small team, nobody here can code, we just need this built for us.

How much does a Square integration cost?

What can you build with Square?

Common Square builds include custom loyalty programs that go beyond Square's built-in loyalty, inventory sync across multiple store locations, and custom kiosk or self-checkout apps built on Square's hardware and payment APIs.

What type of API does Square use?

Square exposes a REST API with OAuth 2.0 authentication, giving developers access to payments, inventory, orders, and customer data for building custom retail and food service apps.

Does Bolder Apps build custom kiosk apps for Square?

Yes. Bolder Apps builds custom kiosk and self-checkout apps on top of Square's payment and inventory APIs, tailored to a specific retail or food service brand's checkout flow instead of Square's generic default.
