# Xero to Logistaas for finance

> Finance controls for Xero payment automation into Logistaas.

Finance owns **cash truth in Xero**. Logistaas needs the same truth without duplicate posts.

## Controls

- Serial format `XERO-{id}` ties Logistaas rows back to Xero identifiers.
- Idempotent handling prevents double payment records when staff or retries collide.
- Recorded process runs support month-end questions without ad-hoc exports.

## Reconciliation stance

Xero remains authoritative for invoice payment state. Logistaas receives an automated copy via create_payment — not a replacement ledger.
