Start with a ledger, invoices and a morning brief. Turn on contracts, close management and multi-entity when you need them — without migrating.
The core ledger, invoicing, bank feeds, tax and a daily brief work on their own. The ERP layer attaches later without touching what exists.
Cash, trailing burn and runway with the basis stated — and an honest 'not enough history' rather than a confident guess.
Append-only journal, reversal-only corrections and an event log, from the first entry rather than from the first audit.
Each of these is a product page describing code that exists.
A seeded company, a close in progress, and every number computed by the engines.
