How AP Invoice Payment Selection Works
Payment selection begins with reviewing open accounts payable invoices in Sage 100. Depending on the company's configuration and procedures, staff specify selection criteria, review qualifying invoices, and prepare a proposed payment batch. The selected items then move through applicable authorization and payment-generation steps.
Before an invoice is included, verify that it has been entered accurately, assigned to the correct vendor, and approved under company policy. Effective invoice matching compares invoice details with relevant purchase orders and receiving records, helping confirm that the amount and goods or services align with the original transaction. Correct invoice dates, general ledger coding, and remaining balances also help ensure the selection reflects valid obligations.
Preparing the Invoice Selection
Start by reviewing open invoices and the accounts payable aging report. Check payment terms, discount deadlines, prior settlements, credit memos, and any disputes or holds that affect payment eligibility. Where purchasing documentation supports the invoice, confirm that the purchase order and receipt information agree with the billed quantities and prices.
- Due dates: Prioritize invoices approaching their contractual payment dates.
- Vendor terms: Identify payment schedules and eligible discounts.
- Open balances: Account for prior payments, credits, and adjustments.
- Payment method: Confirm whether the vendor is paid by check or an approved electronic method.
- Available funds: Compare the proposed batch total with the cash forecast and other upcoming obligations.
These checks make the payment selection more useful for daily payment planning and period-end accounts payable reviews.
Calculating the Selected Payment Total
The proposed payment total is the sum of the amounts due for the invoices selected, after applicable credits, prior settlements, and approved discounts are applied. For example, suppose a payment run includes three invoices with outstanding balances of $4,800, $2,200, and $1,000. The initial selected amount is $8,000. If an approved credit memo reduces the second invoice by $200, the revised payment total is $7,800, assuming no other adjustments.
Use this total to plan supplier disbursements and assess the effect of payment timing on cash flow. Paying an invoice early may be beneficial when an eligible discount outweighs the value of retaining the funds for the remaining period. Reviewing each vendor payment against contractual terms also supports consistent supplier relationships and better working-capital decisions.
Approvals and Payment Controls
Invoice selection identifies the obligations proposed for settlement; it does not replace authorization to release funds. A documented Payment Approval process defines who can authorize a payment batch, approve exceptions, or permit partial payments. The broader AP Approval Process in 2026 - Guide & AI Best Practices topic covers how invoice workflows and approval routing can align with spend categories and company policies.
Strong Payment Approvals should confirm the payment amount, vendor identity, due date, and supporting records before funds are released. Fraud Prevention practices include validating vendor banking details, reviewing changes to payment instructions, and checking for duplicate invoices or disbursements. For eligible electronic transfers, Payment Processing By ACH requires payment instructions that comply with the bank's file format and authorization procedures. These controls help maintain traceability across the payments workflow.
Payment Posting and Reconciliation
After the payment run is processed, review the payment register and vendor account activity to verify that the intended invoices were settled for the expected amounts. An Accounts Payable Payment records the settlement of a supplier obligation and helps explain changes in open payables. When bank activity becomes available, Reconciliation Of Bank Statements connects recorded disbursements with transactions reported by the bank, while Bank Reconciliation supports the wider comparison of bank records and accounting balances.
Investigate differences such as uncleared payments, unexpected remaining balances, or transactions recorded for the wrong amount. Retaining selection criteria, approval evidence, payment registers, and reconciliation results creates a clear audit trail for financial reporting. Consistent review of these records helps finance teams improve payment visibility and make informed decisions about upcoming obligations.
Summary
Sage 100 AP Invoice Payment Selection helps accounts payable teams choose eligible vendor invoices for a planned payment run using due dates, terms, balances, and cash requirements. Accurate invoice records, documented authorization, appropriate payment controls, and post-payment reconciliation support reliable supplier settlements. When these steps are consistently followed, businesses can strengthen vendor management, maintain accurate payables, and plan cash outflows more effectively.
