The challenge

What we were brought in to solve

Independent cafés in the region were stitching together a card terminal, an inventory spreadsheet and a separate scheduling app. CafeFlow wanted to replace all three with a single, multi-tenant SaaS that worked on a tablet, an iPad and a back-office laptop — and stayed usable when the café Wi-Fi dropped mid-rush.

The solution

How we built it

We built CafeFlow as a multi-tenant Next.js + tRPC SaaS with a React Native tablet app for the till. Tenants get isolated data, branded receipts and per-location pricing. The till runs offline-first with local persistence and conflict-free sync to the cloud once connectivity returns.

Stripe Connect handles payouts to each café's account, with automated VAT handling for Spain and Portugal. Inventory, staff scheduling and reporting live in the same workspace so owners stop juggling tools.
