Invco
A multi-tenant invoicing platform with the back-office automated end to end.
The problem
Small businesses lose days a month to the same loop: raise the invoice, email it, wait, check whether it was paid, chase, reconcile the payment against the invoice, repeat. Every step is manual, and every step is where money goes missing.
Why it matters to you
This is the exact shape of work we sell. Scheduled sending, inbound matching, payment reconciliation and accrual are not concepts we have read about — they are jobs running in production, and we can show you the logs.

What we built
- Multi-company workspaces — one login owns and switches between several businesses, with every query re-scoped to the active company.
- Scheduled invoice email, queued and released by a cron worker rather than sent by hand.
- Inbound reply capture over IMAP: client replies are pulled from the mailbox and matched back to the invoice thread automatically.
- A payment processor with account rotation, webhook handling and a reconciliation job that matches settled payments to open invoices.
- A referral system paying 20% recurring, with attribution, daily commission accrual and payout records.
- An OAuth 2.0 server and an MCP interface, so the platform can be driven programmatically with per-user keys.
- Client portal, PDF template engine, rate limiting, and nightly encrypted backups to private release storage.
