✅ Accounts
Ledger, receivables, payables and billing.
✅ Payables
Vendor bills accrue on receipt (V07_10) with net terms and vendorBillPaid postings — live-proven.
✅ Billing
Three rails, decided and built: Stripe tokens, BAC Credomatic (PowerTranz) and SINPE Movil as a reference-and-confirm flow with no bank API — SINPE pay → confirming → confirmed paid proven live; unconfigured rails throw naming themselves.
✅ Collections
Open invoices bucketed by the pure compute-aging, recomputed per read — live-proven totals.
✅ Statements
Periodic per-customer AR documents: opening + invoiced − paid = closing in integer cents, line detail in jsonb, regenerated idempotently per (customer, period end) — live-proven against the collections totals.
✅ Dunning
Per-bucket policies on the compute-aging vocabulary; the sweep mints one notice per (invoice, bucket) behind a DB unique and sends through a Resend-shaped port — unconfigured, notices stay pending; live-proven re-run creates zero.
Evidence
Double-entry for real: chart of accounts and journal postings balance on every proven flow (order → AR invoice, receipt → vendor bill, payment → postings), collections aging recomputes per read, and the dental ledger and commerce ledger speak one vocabulary. Billing is decided and built: Stripe tokens, BAC Credomatic and SINPE Movil.
