Square POS customization and extensions agency

Square POS Customization & Extensions

Custom workflows, receipt templates, kitchen display integrations, and POS extensions — built by the agency Square refers to when the integration is too complex for anyone else.

WHAT WE BUILD

Custom POS Behavior Square Does Not Offer Out of the Box

Custom Receipt Templates

Branded receipts with custom line items, promotional messaging, loyalty point balances, and QR codes — printed or emailed. Built using Square's receipt customization APIs and webhook-triggered post-purchase flows.

Custom POS Workflows

Deposit-first ordering, split-party billing, event ticket validation at the register, membership verification, and custom discount logic that runs inside Square POS without a separate device.

Kitchen Display Integration

Route Square orders to kitchen display systems in real time. Custom routing rules by item type, ticket timing, and station. Works with existing KDS hardware or browser-based displays.

What a POS Project Looks Like

1. Requirements Workshop

We map your current POS workflow, identify the gaps, and define exactly what the extension or customization needs to do. No assumptions.

2. Square API Feasibility

We confirm what Square's API surface allows and where custom middleware is required. We have 4 hackathon wins — we know the boundaries.

3. Build and Test

Extension built and tested against Square's sandbox. Full regression testing against your existing POS setup before any production deployment.

4. Staff Training and Handoff

We train your floor staff on the new workflow and provide written documentation. No black-box deployments.

5. Post-Launch Monitoring

Square API version updates and webhook changes are monitored. We flag breaking changes before they affect your POS.
