tounsils/i-CRM

Self-hostable CRM for firms that invoice: leads, customers, proposals, estimates, invoices, line items, taxes, payments and a correspondence timeline. One static Go binary and one SQLite file, no runtime to install.

← Money

In simple English

This is a simple customer management tool for small businesses that send invoices. It tracks your leads, customers, quotes, and bills in one private place. All your data lives in one file on your own computer or server. You do not need to pay a monthly subscription to run it. It costs you a little time to set up and back up yourself.

What it is

A self-hosted customer relationship management and invoicing system built as a single Go binary with an embedded SQLite database. It packs business rules, HTML templates, and PDF generation into one program with no external runtime required.

What it is good for

Solo builders and small business owners who want complete privacy over their client data and billing without paying for bloated cloud software.

  • Runs as a single lightweight file with zero external database setup.
  • Calculates all money using whole integer cents to avoid rounding errors.
  • Generates matching PDF documents directly from the same view as the web screen.
Watch for
  • Setup requires basic terminal knowledge to configure environment variables.
  • Does not support sending emails or multi-user roles yet.
  • Relies on manual file backups since there is no built-in cloud sync.
