Small business owners don't lose money because they lack a dashboard. They lose it because nobody tells them, in time, that the account goes negative on the 14th and which three overdue customers would fix it. 

Pippe Finance answers that in one sentence, and backs the sentence with the ledger. It's a full financial console — payables, receivables, cash flow, contacts, categories — with an agent layered on top of a grounded tool harness. 

The architecture is the product decision. The language model never writes financial text. It selects from eight typed, schema-validated tools; the server then renders the answer from the tool output alone. Every fact carries a provenance envelope stamped with asOf, source, version and the row IDs it came from.
