Great product. This is needed by effectively every large or mid-size company.
How it works
From journal entry to proof
Perpetual GL that stays current through the month — cryptographic receipts on every posting, period-close attestations for audit and board review, and financeable AR when capital partners need verified receivables. See how we compare.
Step 2
Cryptographic receipts
Every posting writes debits, credits, and a third entry — a tamper-evident receipt tied to the source invoice, payment, or journal. The balance sheet your team exports is the same record a counterparty checks later.
Security & audit →Step 3
Proofs third parties check
Period-close proofs and a hash-chained audit trail give auditors and boards an attestation tied to your live ledger. When you raise or borrow against AR, the same model exports financeable receivable packages capital partners verify in the Verify workspace.
How verification works →Developers
API-first ERP on your tenant
Extend the perpetual ledger with tenant-scoped REST APIs, custom subledgers, and event-driven posting — the same surface area the product uses internally.
Your tenant, your API key
Bearer keys scope to one entity and module permissions. Every write runs in your isolated database with the same RBAC the app enforces.
Custom subledgers
Model protocol treasuries, custody networks, or partner detail ledgers, then reconcile batches into GAAP control accounts.
OpenAPI & event posting
Ingest events, run the posting engine, subscribe to webhooks, and read journal lines — documented routes, not a parallel integration layer.
Luca AI
