Partita Doppia
Every line balanced.
Double-entry books for one small business. Invoices, bills, spend and receive money, transfers, manual journals, bank reconciliation, Xero-style tracking categories and the standard reports, in a Rails 8 app that runs on SQLite and needs nothing else.
Built by someone leaving Xero who wanted to keep the parts that worked and own the rest.
Partita doppia is Italian for double-entry bookkeeping, the method Luca Pacioli codified in 1494. Say par-TEE-tah DOHP-pyah.
What it does
- Documents post to the ledgerInvoices and bills accrue and take payments. Expenses and deposits move money through a bank account, transfers between two, manual journals cover the rest. Each one carries line items, attachments and a history of who changed what.
- Bank reconciliationA nightly SimpleFIN feed or uploaded CSV, OFX and QFX statements. Each line gets a ranked suggestion with a one-click OK, or match it, split it, categorise it, or pair it with its transfer. Bank rules do the repetitive ones. Every match is undoable.
- Tracking categoriesUp to two active categories the way Xero does them, one option per category on any line, and a profit and loss broken out by option.
- ReportsProfit and loss, balance sheet, trial balance, general ledger, receivables and payables aging, profit and loss by tracking category.
- InvoicingNumbered invoices with a PDF, emailed to the customer with the PDF attached, recurring invoices, and a per-document activity log.
- Xero import over the APIPull the chart of accounts, tax rates, contacts, tracking categories, every invoice and bill with payments, spend and receive money, transfers and manual journals. Re-running updates in place. Xero's CSV exports upload as a fallback.
- Passwordless sign-inEvery sign-in emails a six-digit code. An installation can instead trust an SSO hub's cookie.
- Dark and light themesChosen per person, in a terminal-flavoured UI.
