Everything your books need.
Nothing they don't.
Airtight is not a better spreadsheet. It is AI-native accounting built on a cryptographic ledger. Every feature listed here ships on day one or has a clear delivery date.
Core Accounting
The ledger is the heartbeat. Airtight runs on a dual-database architecture: TigerBeetle for sub-millisecond balance lookups and PostgreSQL for everything else. Double-entry is table stakes. Triple-entry is the standard.
General Ledger with triple-entry verification
Every inter-party transaction produces three entries: debit, credit, and a cryptographically signed receipt. Tampering is mathematically impossible.
Chart of Accounts (4 templates)
Start with AU BAS, Sharia AAOIFI, US GAAP, or IFRS templates. Fully customisable. Import your existing chart in seconds.
Journal entries
Create, post, and void journal entries. Never delete. Every entry is immutable once posted, with a full audit trail of who did what and when.
Multi-currency (25 currencies)
Full support for 25 currencies with correct decimal handling: 0 for JPY, 2 for AUD/USD/EUR, 3 for BHD/KWD/OMR. All amounts stored as integers. No floating point. Ever.
Fiscal year & period management
Define your fiscal year start, lock completed periods, and manage year-end close processes. Support for non-calendar fiscal years and split periods.
Real-time trial balance
Balances update in real-time via TigerBeetle. No overnight batch jobs. No stale numbers. Click any figure to drill into the underlying transactions.
Invoicing & Payments
Create professional invoices in seconds, send them in any currency, and get paid faster with built-in payment links. Bilingual support (EN/AR) for businesses operating across the Gulf and Australia.
Professional invoice builder
Bilingual EN/AR invoices with your branding. Line items, tax rates, discounts, and custom fields. PDF export with one click.
Credit notes & quotes
Generate quotes, convert accepted quotes to invoices, and issue credit notes against existing invoices. Full document lifecycle.
Automatic invoice numbering
Sequential numbering with configurable prefixes per entity. No gaps. No duplicates. Audit-compliant numbering by default.
Payment recording & tracking
Record full and partial payments against invoices. Track payment status across all outstanding invoices with a single view.
Aged receivables & payables
See who owes you and who you owe, broken down by current, 30, 60, and 90+ day buckets. Cash flow visibility at a glance.
Online payment links
Send invoices with a secure payment link. Customers pay by card. Funds reconcile automatically. No chasing.
ZATCA QR code ready
Saudi e-invoicing compliance built in. QR codes generated per ZATCA Phase 2 requirements for cross-border invoicing into the Kingdom.
Bank Feeds & Reconciliation
Connect your banks. Let the AI categorise your transactions. Review and approve. Reconciliation goes from hours to minutes.

135+ institutionsFirst licensed open banking provider in MENA. Real-time transaction feeds.
Open BankingSaudi Central Bank licensed. Account aggregation and payment initiation.

Any bankAI auto-categorisation
Machine learning categorises 80% of transactions on day one. Accuracy improves to 95%+ as the model learns your patterns. You review. The AI does the rest.
Rule-based matching
Set custom rules for recurring transactions: "If payee contains Telstra, categorise as Phone & Internet." Rules run before AI, giving you deterministic control.
Three-way reconciliation
Match bank statement lines to invoices and journal entries simultaneously. The triple-entry receipt provides cryptographic proof that all three agree.
Duplicate detection
Automatic detection of duplicate imports, double-counted transactions, and re-posted entries. Flagged before they corrupt your books.
Financial Reporting
Every report updates in real-time. Every number is drillable to source. Every figure is cryptographically verifiable. Export to CSV, PDF, or Excel with one click.
Profit & Loss
Revenue vs expenses with period comparison. Drill into any line to see the underlying transactions.
Balance Sheet
Assets, liabilities, and equity. Always balanced, always current. Comparative view across periods.
Cash Flow Statement

Bilingual report headers
Generate reports with English and Arabic headers side by side. Professional output for dual-language businesses.
Export: CSV, PDF, Excel
One-click export in any format. Consistent formatting. Branded PDF headers with your company details.
AI Intelligence
AI handles the repetitive work. You handle the decisions. One immovable rule: financial calculations are never delegated to AI. Every dollar amount is computed by deterministic code.
Transaction categorisation
Machine learning models trained on millions of transactions suggest the correct category. Accuracy starts at 80% and improves with every correction you make.
Bank reconciliation suggestions
AI matches bank statement lines to invoices and journal entries. Confidence scores let you approve high-certainty matches in bulk and review the rest.
Anomaly detection
Statistical models flag unusual transactions: duplicate payments, amounts outside normal ranges, vendors billing from new bank accounts, and timing anomalies.
Cash flow forecasting
Predict your cash position 30, 60, and 90 days out based on historical patterns, recurring invoices, and scheduled payments.
Receipt OCR
Snap a photo of a receipt. AI extracts the vendor, amount, date, and tax. Creates the transaction for your review.
AI co-pilot
Ask questions in plain English: "What were my top 5 expenses last quarter?" or "Show me all unpaid invoices over $5,000." Natural language access to your data.
The Airtight AI guarantee
AI in Airtight handles pattern recognition, categorisation, and natural language queries. Financial calculations -- every dollar, every cent, every tax rate -- are computed by deterministic, auditable code. No LLM touches your numbers.
Security & Encryption
Financial data demands the highest standard of protection. Every byte of your data is encrypted at rest and in transit with keys only you control. When you leave, we destroy the keys. The data becomes permanently unreadable.
Per-tenant AES-256 envelope encryption
Four-layer key hierarchy: CMK wraps KEK wraps DEK wraps field keys. Each organisation gets its own encryption envelope. A breach of one tenant exposes zero data from any other.
Cryptographic shredding
On account deletion, encryption keys are destroyed. The ciphertext becomes permanently unrecoverable. Not file deletion. Cryptographic annihilation.
Passkey-first authentication
WebAuthn/FIDO2 passkeys as the primary login method. Phishing-resistant by design. TOTP as fallback MFA. Passwords are legacy migration only.
Zero-trust architecture
Every request is authenticated and authorised regardless of origin. mTLS between all services. No implicit trust based on network location.
Event-sourced immutable audit trail
Every state change emits a hash-chained event. Click any number in any report and trace it to the source, the person who entered it, and every modification.
Merkle tree verification
Receipts are chained into a Merkle tree. Verify the integrity of any individual transaction without downloading the entire ledger. Offline-verifiable.
Ed25519 cryptographic signatures
Triple-entry receipts are signed with Ed25519 keys. Both parties sign. The signature proves the receipt has not been altered since creation.
BYOK encryption (Enterprise)
Enterprise customers supply their own encryption keys via AWS KMS, Azure Key Vault, or Google Cloud KMS. You hold the keys. Literally.
Multi-Entity Management
One login. Every business. Manage up to 24 entities from a single dashboard with consolidated reporting and intercompany eliminations. One set of books per entity, one view across all of them.
Each entity has its own chart of accounts, currency, fiscal year, and compliance settings. Completely isolated. Fully consolidated on demand.
Consolidated reporting
Generate combined P&L, balance sheet, and cash flow across all entities. Filter by entity, region, or custom grouping.
Intercompany eliminations
Automatic elimination of intercompany transactions in consolidated reports. Track intercompany balances with full audit trail.
Per-entity permissions
Grant users access to specific entities. A bookkeeper sees their client. An owner sees everything. Role-based access control at every level.
