Buyer AP teams and material suppliers coordinating invoice and payment enquiries.
Buyer AP teams and material suppliers coordinating invoice and payment enquiries.
Submit the supplier invoice with its buyer and purchase-order references. Keep submitted amounts and documents separate from the buyer’s receipt matching and approval outcome. An upload cannot bypass the payable system’s controls.
Show the confirmed due date and open balance from the latest source observation. Suppliers can distinguish an invoice awaiting review from one approved but not yet included in a payment instruction.
Retain the invoices covered by a payment and any observed discount allocation. A remittance file explains the composition while the associated source state indicates whether funds are scheduled, pending or settled.
Open a source-linked case for missing references, partial payment or another discrepancy. Supplier-visible replies provide the relevant answer while internal AP notes and unrelated vendor documents remain protected.

Related questionSubmission sends the supplier document to the buyer. The portal retains the actual acceptance or rejection response, while financial approval and confirmed payable status remain owned by the buyer’s AP system.
Related questionEach active membership explicitly identifies the supplier and buyer relationship. Records, search, exports and saved file links enforce that scope. Similar names or a shared email domain do not grant another vendor’s access.
Related questionEach displayed status identifies its latest reconciled source revision and observation time. Older or conflicting events cannot silently replace a newer result. Missing or stale source information remains visible as an unresolved observation.
Related questionThe document explains the buyer’s payment composition. The associated source payment state separately shows whether the instruction is scheduled, pending, settled, failed or reversed.
Related questionAn active Supplier Admin can accept an eligible published offer before its exclusive deadline. The exact terms are retained, and the buyer must confirm the reservation. An ordinary Supplier User can read the offer but cannot accept it.
Related questionSupplier acceptance and buyer confirmation establish the arrangement. Realised discount comes from the observed payment allocation and the settlement conditions in the accepted terms; failed or late payment cannot automatically be reported as realised savings.
Related questionA Supplier Admin can request a protected destination change. AP Specialist verifies identity through an established channel, a different AP Manager approves, and the active profile changes only after the owning AP system confirms application.
Related questionInternal notes and files are excluded from supplier record access, search, notifications and exports. Vendor-visible messages provide the permitted answer, and document links recheck current membership and visibility.
