Posting Pipeline

1. Source Event

Invoice issued, POS sale completed, journal posted, bill approved, payment confirmed, correction requested.

→

2. Posting Engine

Checks idempotency, validates account rules, balances entries, opens one atomic transaction.

→

3. Ledger Transaction

Immutable business and branch-scoped transaction header plus debit and credit entries. Reports derive from entries.

Legacy risk pattern

Feature modules write individual ledger rows and use local commit tables. Edits often delete/recreate rows.

Rebuild target

A single posting engine writes complete balanced transactions. Edits produce reversal and replacement transactions.
