An ERP that reads like the textbook.
Most cloud ERPs grew organically over fifteen years and it shows. Buckeroo Books is a clean-sheet design built around how double-entry accounting actually works — with the software engineering standards modern finance teams expect.
Four design choices that shape everything
Modular monolith
Each accounting domain — ledger, AR, AP, cash, inventory, rev-rec — is a bounded context with its own service layer. One deployment, clear boundaries, no distributed-transaction pain.
Single source of truth
Every subledger posts to the same general ledger. Subsidiary totals equal GL control accounts by design, not by a nightly reconciliation job.
Tenant-safe by construction
Row-level tenant scoping lives in middleware, not sprinkled through queries. A missing tenant context throws instead of leaking data across customers.
Serverless by default
Lambda + API Gateway + Postgres on AWS. Cold-start budgets are tracked in ops runbooks. You pay for what you use and scale to zero overnight.
What's in the box
The foundation you need to run a real finance org — not a long tail of integrations you have to stitch together yourself.
- Double-entry general ledger with configurable chart of accounts
- Soft-close and hard-close for period controls
- Multi-entity consolidation (full, proportional, equity methods)
- Multi-currency with daily FX revaluation
- Dimensions: department, project, location, and custom tags
- Append-only journals with signed audit trail
- Role-based permissions with segregation-of-duties checks
- Per-tenant backup, restore, and GDPR-compliant erasure
