One ledger for the whole financial operation
From the first invoice to period close, LedgerOS covers the full accounting lifecycle for contractor compliance businesses.
Double-entry general ledger
Every posting is balanced debits-to-credits and immutable once posted, enforced by database triggers — not application code.
Invoices & accounts receivable
Draft, send, and post invoices to per-line revenue accounts, with recurring billing, credit notes, and AR aging.
Payments, credits & refunds
Record payments atomically — applications, invoice balances, and the journal entry all move together, mapped by payment method.
Bills & accounts payable
Manage vendors, bills, and AP payments with aging visibility so nothing slips past its due date.
Banking & reconciliation
Import transactions, match them to the ledger, and reconcile accounts with a clear, auditable trail.
Fixed assets, tax & period close
Track assets and tax positions, then close each fiscal period — postings outside an open period are rejected automatically.
Apex intelligence layer
A dedicated insights workspace surfaces company health, cash signals, and opportunities on top of your live ledger.
ServiceConnect integration API
A public integration surface lets your operational systems push financial events straight into balanced, posted journals.
From operational event to trusted books
Three steps take you from your existing systems to a clean, closable set of books.
- 1
Connect your operations
Wire your existing systems to LedgerOS through the ServiceConnect integration API, or work directly in the app.
- 2
Automated double-entry posting
Financial events become balanced, immutable journal entries the moment they arrive — no manual bookkeeping.
- 3
Real-time reporting & close
See company health live, then close each period with confidence backed by a complete audit trail.
Compliance enforced by the architecture
Controls a compliance-conscious buyer cares about aren't bolted on — they're structural guarantees of the platform.
Row-level security everywhere
Access control is enforced on every table, so tenants only ever see their own data.
Strict tenant isolation
Multi-entity contractor operations are partitioned by organization from the ground up.
Immutable audit trail
Posted entries can only be voided, never edited or deleted — every change is correlated to an audit event.
Atomic posting & exact money
Postings commit as one balanced transaction, and all money is stored as exact NUMERIC — never floating point.
