Accounting engines cannot afford rounding errors, unclosed transactions, or phantom ledger discrepancies. Double-entry bookkeeping guarantees absolute mathematical balance across credits and debits.
1. Immutable Journal Entries & Zero-Delete Policy

When offering software as a service (SaaS), you can isolate client data using Row-Level Security (RLS) with tenant identifiers on every table, or separate database catalogs per enterprise for high-compliance healthcare and financial contracts.
