Invoices computed by code, issued by you
Money is arithmetic, not prose. Invoice totals, taxes and dates are computed deterministically; the model may describe an invoice, but it never calculates one. Issuing is an external action with its own approval.
Prices are published at launch; every account starts with a trial. No card to start.
The invoice lifecycle
Draft
Lines, quantities, unit prices, tax and currency; totals are computed and re-checked on every change.
Issue
An external action: previewed, approved, then issued — with a PDF generated from the stored invoice, not from a template a model filled in.
Paid or void
State changes recorded with who and when; a void keeps the record.
Documents
Each issued invoice has a PDF in Documents. Generating other office documents — DOCX and XLSX from company data — is the same deterministic path.
Payments
Taking a payment or issuing a refund are financial actions with a financial approval level and per-plan limits, available once a Stripe account is connected through Stripe Connect on Advanced and above.
Questions people ask
Can the Assistant change an invoice total?
No. Totals are computed from lines by code; the Assistant can propose a line change, which is previewed and recomputed.
