Context

Client Context

Swiss craftspeople spent more time on paperwork than on real work. Offers in Word, rapports on paper, invoices in Excel, time tracking in a third tool — all error-prone, slow, and unscalable.

Challenge

Build a SaaS platform covering the full workflow — mobile-ready on site, offline-capable, with Swiss QR invoicing and automated bank reconciliation. Multi-tenant so dozens of businesses run securely in parallel.

Solution

Industry-specific platform with an end-to-end pipeline: offer → rapport → QR invoice → bank reconciliation. One system, no tool switching.

Mobile-first on Next.js and React, offline-capable with local sync, photo documentation directly from the app. Multi-tenant architecture using row-level security in Supabase, role-based access control (RBAC) at both function and data layers.

Stripe integration for subscriptions. Trade-specific service catalogs aligned with Swiss standards. 58 database tables, 143+ functions — cleanly documented.

Result

A market-ready platform with 58 database tables and 143+ functions. Invoicing reduced from hours to minutes. Automated bank reconciliation. Trade-specific service catalogs live. Multiple Swiss construction businesses run on the platform in parallel through the multi-tenant architecture.
