How it works
From feeds to proof
Connect your accounts once. Luca runs the books from there, and the proof is ready the moment a counterparty asks. See integrations.
Step 2
Luca keeps it current
Luca posts and reconciles through the month, so the books are always close-ready — and every entry links to the invoice, payment, or journal behind it.
Security & audit →Step 3
Prove it on demand
Export a certified close or receivable package the moment someone asks — each one carries its own proof. Share a link to the signed certificate, or open it in Desktop and the check confirms on the spot, valid or invalid.
How verification works →What you get
Books your counterparties can verify
Luca runs the ledger across every module. Every balance is complete, traced to source, and tamper-evident — so your auditors, lenders, and regulators can verify it themselves.
Numbers you can prove
Every balance carries a tamper-evident trail and cryptographic proof. Your auditors, lenders, and regulators verify it themselves — no access to your books required.
How verification works →Luca does the work
Luca posts transactions, reconciles accounts, and books routine work from your rules — then sends a daily digest of what it handled and what needs your attention.

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 — same REST routes as the web app, with a full OpenAPI spec.
Native modules
Every department, fully integrated
Each module is built natively on the same ledger and identity model. Turn on what you need today; add the rest as you grow.
