Manage Tax Compliance


Buyer Org Perspective: Requisition to PaymentB3. Invoice to Payment (AP)

Acronyms: AP: Accounts Payable, JEs: Journal EntriesPO: Purchase Order, KPI: Key Performance Indicator

Preconditions: A purchase order has been created and sent to the Seller Organization.

A supplier invoice usually triggers the Invoice to Payment process. In process step B3.1, a supplier submits an invoice to the buyer organization, usually after they’ve picked, packed, and shipped product to the buyer (although pre-payments sometimes occur). The invoice is reviewed for accuracy and entered into a payables system for matching purposes. This can also trigger the flow of information to Capital Asset management tracking for depreciationpurposes, Project Accounting for project financials tracking, Tax for compliance reporting, and the General Ledger to account for liability owed. In process step B3.2, the buying organization’s Accounts Payable group/person then canperform a 3-way match between the original PO, the materials Receipt, and the Invoice. Process step B3.3 illustrates how some alternative purchasing models can be accommodated, such as direct orders, employee expense reportsubmission (which requires payment to the employee) or procurement card (like a credit card) based purchases, where a the requisition and PO is entirely bypassed. Process B3.4 allows for these alternative 3-way matching scenarios, as the invoice is approved and verified before payment is made to the vendor. In the event of match exception or out of tolerance scenarios (where amount invoiced is considerably different than expected), Accounts Payable notifiesthe requester of over tolerance (which could trigger a PO change) or rejects (disputes) the invoice (B3.5). In process step B3.6, Accounts Payable (or the Buyer) contacts the Supplier to resolve the rejected invoice. If matching andtolerance proceeds as planned, in process step B3.7 the invoice could be held in a pending state until a settlement period has been reached, optimizing working capital. Payment is then remitted to the supplier either electronically (viaa banking institution) or manually via a cheque-run (step B3.8). The invoice to payment process asserts a tight audit trail, which enables AP to know everything about the invoice and payment, supporting the ability to investigate andrespond to supplier payment issues (process B3.9). As mentioned above with the non-PO purchasing models, process steps B3.10 - B3.12 provide further details around procurement card purchasing verification and paymentprocessing since it evokes a different payment model - to the bank as opposed to the supplier (since payment has already been made). Finally, in steps B3.13 - B3.15 related vendor data maintenance processes are performed, whichplay an important role in ensuring correct and proper payment to suppliers, as well as avoiding late charges resulting from incorrect payments (locations, addresses, bank acct #s, etc).
