`purchase_invoice_id` (invoice identity)

purchase_invoice_id (invoice identity)

purchase_invoice_id is the stable identity of a purchase invoice. Bookkeeping uses it to link documents, supplier, posting specification lines, and bank matching so the audit trail remains navigable from a posting back to the vendor invoice evidence.

Stable invoice identity also supports deduplication and makes exports and later corrections traceable.

Example values: PI-2026-000045, PI-2026-000046.
