Overview
Ledger is a Deal Desk for shops that turn valuable things into cash: find the person, fill a ticket, finish. Built to replace spreadsheet-and-paper pawn workflows with one Postgres-backed system of record.
Product
Today Desk for overdue work and cash, loan create with gold appraisal, customers with notes and tags, inventory and buy-side purchases, cash register tied to deals. Plain counter language, not seventeen settings screens.
Architecture
How it holds together
Forced RLS
Every row scoped by
business_id. Permissions live in SQL.Append-only money
Contract mutations, snapshots, cashbook: cents only, auditable.
Pure core
Pricing and loan rules in TypeScript; Server Actions stay thin.
Local-first, honest about cash
TanStack DB for speed at the counter. Money mutations stay online.
Pilot
In pilot with a pawnshop in Bonaire, in the Caribbean. Decisions come from counter time, not decks.
