Invoice Collection SaaS for Service Businesses

A full-stack B2B SaaS built to help contractors, tradespeople and service businesses recover overdue invoices and manage accounts receivable from one workspace.

The platform includes customer and invoice management, configurable automated collection workflows, Promise-to-Pay tracking, payment behavior scoring, transactional reminder emails and analytics for outstanding, overdue, recovered and at-risk payments.

The product is built with TypeScript, React, TanStack, Supabase and PostgreSQL. The product includes authentication, account-level data isolation with Row Level Security, database infrastructure, collection workflow logic, analytics and transactional email delivery through Resend.

This project is currently pre-revenue and has not yet been commercially launched or marketed to end users. No revenue or customer traction is being claimed. A buyer can therefore focus on customer acquisition and commercialization instead of rebuilding the core product.

Growth opportunities include SaaS subscription plans, QuickBooks or Xero integrations, online payment processing, expanded reporting and automation, and partnerships with accountants or bookkeeping firms.

The sale includes the source code, database schema and migrations, Supabase configuration, authentication and security setup, Resend integration, environment variable template and technical documentation.
