MaintenanceSaaS
A multi-tenant ops platform that turns vendor sourcing, work orders, and billing into one workflow.
Problem
Property managers were juggling spreadsheets, text threads, and a separate accounting tool just to dispatch a vendor and get paid. Tenant data wasn't isolated, vendor sourcing was manual, and nothing reconciled cleanly with QuickBooks.
Approach
I designed a multi-tenant Supabase backend with Row-Level Security on every table, role-based access enforced in the database via a has_role SECURITY DEFINER function, and an append-only audit trail. Vendor discovery pulls from DataAxle, Clearbit, Yelp, and Google Places. Work orders flow through tokenized approval links so vendors and tenants act without an account, and accepted jobs sync straight to QuickBooks.
Features
- Multi-tenant isolation with Row-Level Security on every table
