Challenge

A restaurant group was running each location on its own spreadsheets, POS exports, and Telegram threads. Owners had no same-day view of sales or stock across locations, and every new branch multiplied the manual work. They had been quoted agency timelines measured in quarters.

Solution

We built RestoSync as a multi-tenant SaaS: each brand is a tenant, each location a scoped unit inside it, with role-based access from owner down to shift staff. The 27 modules cover orders, menu and pricing, inventory with stock alerts, staff scheduling, and cross-location reporting. Weekly demo sprints meant the client clicked through real screens from week two.

Architecture

We show real architecture. Agencies never do.

A NestJS modular monolith over PostgreSQL, with Prisma enforcing tenant isolation at the data layer: every one of the 31 models is tenant-scoped and every query passes through a tenant-aware client extension, so isolation is code, not convention. The Next.js back office is server-rendered for fast first paint on restaurant hardware, and Redis handles caching and background jobs like report generation.

Results

  • One platform replaced per-location spreadsheets and manual POS reconciliation
  • New locations onboard through configuration, not development work
  • Owners see cross-location sales and stock the same day instead of at month end
  • Tenant isolation verified by automated tests on every release
We stopped guessing what was happening in our other branches. The numbers are just there every morning.
