Review the effective date of a vendor payment-terms change
Separate master-data maintenance from commercial approval and determine which invoices a newly approved payment term should affect.
Direct answer
What this role should do
Record the old and proposed terms, approval authority, effective-date rule, affected entities, and open invoices. Update master data only after approval, then review existing documents separately instead of assuming the new term rewrites them.
Define the requested change in commercial terms
A request to change a vendor from net 30 to net 45 sounds like a single field update, but the date it takes effect can alter cash timing, discount eligibility, supplier expectations, and overdue reporting. Preserve the request and identify the supplier legal entity, internal vendor account, buying entity, currency, old term code, proposed term code, stated reason, requester, request date, and proposed effective date. Expand each code into its controlled meaning. Two systems may use the same label for different base dates, discount windows, or calendar adjustments, so the readable rule belongs in the review packet.
Separate the term itself from related requests. A supplier may also ask for a new remit address, bank account, billing contact, or tax treatment. Those changes follow their own verification and approval paths. Likewise, a buyer may negotiate a term in a contract amendment that applies only to one business unit or category. Do not update every account under a similar supplier name. Name the exact entity and purchasing relationship covered by the evidence, and record accounts intentionally outside scope.
Locate authority for the term and its start date
Find the contract, purchase-order amendment, procurement approval, finance policy, supplier agreement, or other controlled record that authorizes the change. An email from an AP mailbox may transmit the request without proving commercial approval. Record the document version, signatories or approval reference, covered entities, effective-date language, and any conditions. If the agreement is silent about invoices already issued or orders already placed, raise that question to procurement or finance. The AP preparer should not choose the interpretation that produces the cleaner aging report.
Dates need precise labels. Contract signature date, amendment effective date, order date, delivery date, service period, invoice date, invoice receipt date, posting date, and master-data update date can all differ. Ask the owner which event determines applicability and cite the answer. Avoid a note such as "effective immediately" unless the record says what immediate means and when it was approved. A clear rule might apply the new term to invoices issued on or after a date, to new purchase orders, or only to transactions under an amended agreement.
Inventory open documents before the master update
Export or record the supplier’s open invoices, parked documents, blocked invoices, unmatched receipts, credit memos, payment proposals, and disputes for the covered entity. Include invoice number, amount, currency, source term, calculated due date, discount date, order reference, status, and current proposal membership. This snapshot shows what the system believed before the change. It also prevents a later bulk recalculation from looking like the original invoice terms. Protect sensitive fields and store the inventory with the approved change case.
Group the documents by the controlling event specified by the owner. Some invoices will clearly remain on the old term, some will clearly take the new term, and others may need individual review because they cover a transition period or use a conflicting purchase order. Keep the uncertain group visible. Do not assign the new term merely because the invoice is unpaid on the update date. Payment status is not evidence that the commercial rule changed, and an overdue invoice may still need supplier dispute handling under its original due date.
Prepare the master-data action without backdating evidence
The change instruction should name the vendor account, company or purchasing organization, old value, new value, system effective date, approved business effective date, and authorized reviewer. If the ERP does not support future-dated terms, document the controlled scheduling method and the owner responsible for execution. Do not enter an earlier system date to make the field appear as though it always held the new term. Preserve the change log and ticket reference so later reviewers can distinguish the agreement date from the actual system maintenance date.
Use separation of duties required by company policy. The person assembling evidence need not be the person approving commercial terms or releasing payments. Limit access to the relevant master fields and avoid using broad administrator rights for a routine update. If the system change affects multiple company codes, test each scoped account rather than assuming the global view propagated correctly. Record accounts that failed or were intentionally excluded and route them to the appropriate master-data owner.
Handle existing invoices as explicit decisions
After the master update, review whether the ERP recalculated open documents. Some systems copy terms at invoice entry and leave them unchanged; others allow a manual due-date adjustment or mass update. Compare the pre-change snapshot with the current values. For every changed open invoice, retain the previous due date, new due date, reason, approval, and system document history. If the owner decides that existing invoices stay on the old term, confirm that the master update did not silently move them.
Discounts deserve a separate check. A move to a longer net term does not necessarily change an early-payment discount, and a new discount should not be claimed on an invoice outside the approved scope. Payment proposals already prepared may also contain the old calculated date. Report affected proposals to the payment-run owner, but do not add, remove, or release payments without authorization. If a supplier statement continues to show the old due date, send the effective-date evidence through a verified contact and retain the response.
Verify the first transactions and close the change record
Test the next ordinary invoice covered by the new rule. Confirm that the correct supplier and buyer entity inherited the intended term, base date, due date, discount fields, and calendar adjustment. Compare those results with the approved agreement rather than only checking that the new code appears. Also sample an invoice that should remain under the old rule. This boundary test is more useful than checking one favorable example because it shows whether scope and timing were configured correctly.
Close the case with the source request, commercial authority, effective-date interpretation, open-document inventory, approvals, system change log, exception decisions, supplier communication, and test results. Schedule a follow-up when the change is temporary or tied to a contract end date. In an outsourced AP arrangement, define which tasks are evidence gathering and controlled maintenance and which stay with procurement, finance, treasury, or legal. The final record should answer who approved the term, what transaction population it covers, when the system changed, and why each affected invoice has its current due date.
Continue with vendor onboarding administration and the payment run preparation.

- Covered supplier and buyer entities are explicit
- Open documents were inventoried before maintenance
- Existing invoice changes retain prior values and approval
- Boundary transactions passed post-change testing
Common questions
Accounts payable virtual assistant FAQs
Does changing vendor master terms update old invoices?
System behavior varies, and commercial scope is a separate question. Inventory open documents, apply the approved effective-date rule, and retain any invoice-level changes.
Can AP decide whether the term applies retroactively?
No. AP can identify affected documents and system behavior, while procurement or finance interprets the approved agreement and authorizes treatment.
What dates should the record preserve?
Keep the request, approval, agreement effective date, relevant transaction dates, actual system maintenance time, and invoice-level change dates.
