Immutable documents
Corrections are reversals — money records never silently change.
Solutions · Finance & cash
Invoices, payables, receivables and cash land where the trades happened — no month-end reconstruction.
Problem
The trade posts today; its money story is assembled at month-end from exports. Payables and receivables live in sheets nobody trusts.
Recognition
If answering “where is our cash?” means exporting three systems into one sheet, finance is reporting on a business it cannot see.

Mechanism
Invoice from sale
Issuing runs off the sale you already posted — same items, same prices.
Payables track
Purchase commitments surface as payables with their due state.
Cash lands
Settlements post to trading cash accounts on the same books.
Economics derive
Revenue, gross profit and working capital read off posted history.
Proof
Corrections are reversals — money records never silently change.
Finance shares state with trading — no parallel ledgers to reconcile.
Postings and payments are logged as they happen.
Next step
See your trades close into cash and economics on one record.
