Everything your books
need. Nothing they don't.
Nine feature groups, 170+ capabilities, one cryptographic ledger underneath. Everything that ships today is listed here. Everything that's coming has a date.
The cryptographic engine under everything.
Every transaction in Airtight is debited, credited, and sealed with a signed receipt. Ed25519 keys, SHA-256 hash chain, Merkle-anchored. The third entry is the proof no one can argue with.
TigerBeetle for balances, PostgreSQL for everything else. One source of truth, built for audit.
Offline-verifiable. Publishable. Pastable into email — the recipient can verify with no Airtight login.
Every state change emits an immutable event. Projections can be rebuilt from scratch.
Daily anchor to a public chain. Tampering with yesterday breaks tomorrow.
End-of-year export, cryptographically signed. Your auditor can't argue with maths.
Point-in-time reconstruction of the ledger. Subpoena-ready.
Autonomous. Guarded. Off, when you want.
Bella is an always-on agent that lives inside your ledger. She reconciles, categorises, drafts returns, chases clients, flags anomalies. Every action she takes leaves a signed receipt so you can audit her later. Take the wheel any time.
Every bank feed, every e-com channel, every Stripe payout. Matched before you wake.
Learns your chart of accounts. Accuracy improves with every correction.
Ask "close last month" or "why is gross margin down?" She answers with numbers and receipts.
EN-AU and EN-NZ first, with Arabic, Mandarin, Vietnamese and Hindi available for client-facing surfaces — the languages AU/NZ small businesses actually run in.
Duplicate invoices, supplier drift, unusual wages. Flagged in plain English.
Pause Bella on any entity any time. She stops writing — keeps watching.
135+ AU banks. Every NZ major. Ten e-commerce rails.
Connect once, reconcile forever. Bella matches payments to invoices, payouts to sales, refunds to credit notes — and explains anything she can't.
All four majors, every regional. Live, not CSV.
ANZ, ASB, BNZ, Westpac NZ, Kiwibank, Heartland, Co-operative Bank — direct feed, not screen-scraped.
Payout splits, refunds, fees all matched to the right lines automatically.
Orders → invoices, payouts → bank, GST → return. Already linked.
Bank feed in USD, books in AUD or NZD? Bella revalues daily.
Teach her once, she remembers forever.
Issue, chase, collect, reconcile — on her.
From quote to settled invoice with zero chase-work. Templates branded to your business, with multilingual receipts where you need them. Payment links, recurring plans, dunning ladders — all built in.

Finalisation, pay events, update events. All ATO-cleared.
Every state's rule, every entitlement, every accrual. Correct to the hour.

Unfalsifiable numbers, on-brand deck, ready to send.
Every AU + NZ regulator, one ledger.

Your keys. Your data. Never ours.
Four-layer envelope encryption, per-tenant keys, cryptographic shredding on deletion. Passkeys first. Row-level security on every table. MFA, SSO, API keys with surgical scopes.
CMK → KEK → DEK → field. Your org's keys, never shared.
Delete a tenant, lose the key. Data becomes unrecoverable, not "soft-deleted".
WebAuthn passkeys first. TOTP fallback. No SMS — SMS isn't security.
Postgres RLS on every tenant table. Cross-tenant queries physically refused.

Scope to module + read/write + IP range. Rotate without downtime.
Plays nice with everything you already run.
