Features
Every page below documents code on the main branch — not a roadmap. Each deep-dive shows the actual data model, the actual endpoints, and the rules the running app enforces.
GST returns
GSTR-1 + GSTR-3B downloads, plus the headline feature: GSTR-2B reconciliation with 4-bucket diff and inline-create from portal-only rows.
Invoicing
Draft → finalize → cancel state machine. Gapless per-FY numbering via SELECT FOR UPDATE. Intra-state vs inter-state tax math auto-computed from supplier state and place-of-supply. PDF + R2 storage.
Quotations
Quote → public share URL (no auth needed) → WhatsApp → accept → convert to draft invoice in one click. The full pre-sale flow.
Suppliers & purchases
Inward-supply ledger with per-line ITC eligibility. §17(5) auto-suggestion flags blocked categories (motor vehicles, food/beverages, etc.) from the HSN code as you type.
Payments
Partial allocation across invoices. Seven payment modes. Idempotency-Key support so a flaky network never double-records.
Compliance & security
Postgres Row-Level Security enforced at the DB layer. Append-only audit log with DB triggers. DPDP §8(8) IP + UA capture on every signup. 6-year GST retention via JSONB snapshots.
