Bookkeeping & Finance
SaaS, open source and skills for bookkeeping & finance work — with the limits of each written down.Before you pick
What decides it
Every tool automates most transactions. Who works the leftover exceptions, and whether they also file your return, decides this.
What to avoid
Migration is the regret: prior-year history arrives incomplete, tax codes and chart of accounts don't map across, and receipts attached to transactions rarely export.
What is changing
The close is going continuous: agents reconcile overnight and queue journal entries for human approval, and ledgers are opening to outside agents through APIs.
