Connections

• Platform accounts. Associate each Users identity with the appropriate team members record and organization membership.
• Supplier channel. If orders are sent outside the app, agree how the order reference and supplier acknowledgement return to the parent purchase request.
• Invoice system. If invoices are handled elsewhere, record the invoice reference on the accepted purchase line and reconcile the external result there.

Name the owner of each external handoff before the first order. If an external action writes an operation receipts record, preserve the request number, operation key and expected revision. A Purchasing Approver should inspect a Failed or needs review result beside the parent request before deciding what happens next.
