Standardize Invoice Entry and Validation
Consistent invoice entry creates a reliable starting point for the AP process. Define how staff should record supplier names, invoice numbers, invoice dates, due dates, currency, tax details, payment terms, and general ledger accounts. Use the fields and validation rules available in your Epicor configuration to promote consistent records across users and business units.
Before posting an invoice, employees should verify the supplier, check for duplicate invoice references, confirm amounts, and review supporting documentation. Where invoices relate to purchase orders, compare the invoiced quantities and prices with the order and receipt records. Clear procedures for credit memos, freight, tax adjustments, and non-purchase-order invoices help ensure each transaction is recorded appropriately.
Organizations can use AP Automation Software to connect invoice capture, validation, coding, and payment planning with controlled AP workflows. When implementing automation, establish which fields are validated automatically, which exceptions require review, and who is authorized to approve or correct transactions.
Strengthen Invoice Matching and Accounting Controls
Invoice matching should follow a documented process that compares invoice details with relevant purchase orders and receiving records. Define acceptable tolerances for price and quantity differences, and assign responsibility for resolving unmatched transactions. These rules help employees distinguish valid variations from records that need additional evidence before posting.
Reliable invoice processing also depends on accurate gl coding. Train AP staff to select accounts and cost centers based on the nature of the purchase, the applicable accounting policy, and the supporting documentation. Review recurring supplier transactions periodically to identify coding inconsistencies and improve standardization.
Two related controls should be understood separately. AP Invoice Matching Approval concerns authorization associated with the invoice-matching workflow, while Accounts Payable Matching Approval describes approval within the broader AP matching process. Organizations should configure the appropriate approval rules and maintain evidence of the decision.
For a deeper understanding of capture, validation, matching, coding, and posting, teams can review How Vendor Portals Improve Invoice Transparency alongside their internal procedures. Transparent status updates help AP staff and suppliers understand whether an invoice has been received, is awaiting approval, or is ready for payment.
Manage Approvals, Payments, and Supplier Records
Approval workflows should reflect transaction value, department responsibility, budget ownership, and segregation-of-duties requirements. Maintain an approval matrix that identifies who can approve invoices, who can release payments, and who can change supplier bank details. Review user access when employees change roles and retain the records required by company policy.
Payment Approval is the authorization that permits a payment to proceed under defined financial controls. It is distinct from approving the supplier invoice: invoice approval confirms the transaction can be recorded, while payment approval governs the disbursement. Before a payment run, check due dates, payment terms, discounts, cash availability, and any payment holds.
Maintain accurate supplier master data, including legal names, remittance addresses, payment terms, tax information, and bank details. Changes to sensitive information should follow an independent verification process. Strong vendor management helps keep supplier records dependable, supports timely communication, and improves coordination when discrepancies or payment questions arise.
AP procedures should also align with procurement so that purchase orders, goods receipts, and invoices share consistent information. This connection helps teams trace a transaction back to its business purpose and resolve discrepancies with purchasing or receiving staff.
Use Reporting and Automation to Improve AP Performance
Review AP reports on a defined schedule rather than waiting until the financial close. Useful reports include unpaid invoices, overdue liabilities, invoices awaiting approval, unmatched transactions, supplier balances, payment runs, and duplicate-invoice exceptions. Assign an owner and follow-up date to each material exception so outstanding items progress toward resolution.
When reviewing accounts payable workflows, assess whether invoices move through capture, validation, matching, coding, approval, and posting with consistent data. A practical improvement measure is the percentage of invoices processed without manual correction. For example, if 800 of 1,000 invoices require no correction during a reporting period, the no-correction rate is 80%.
Use invoice matching results and exception reports to identify recurring causes, such as missing receipts, inconsistent purchase order details, or incorrect accounting assignments. Address the underlying process issue rather than correcting only individual transactions. Document how automation handles routine cases and how employees review exceptions before posting or payment.
Prepare for Month-End Close and Continuous Improvement
At month-end, review invoices received but not yet entered, goods or services received without corresponding invoices, pending approvals, supplier statements, and outstanding payment items. Apply the organization's accrual policy so expenses and liabilities are recorded in the appropriate accounting period. Reconcile AP subledger balances with the general ledger and investigate material differences before closing the period.
Teams should periodically review transaction accuracy, invoice approval time, overdue invoices, duplicate detection, exception resolution time, and supplier inquiries. Compare results across periods to identify trends, then update training, workflow rules, and reference procedures. Changes to Epicor configuration should be tested in an appropriate environment and communicated to affected users before deployment.
Summary
Epicor AP Best Practices combine standardized invoice entry, accurate coding, documented matching rules, controlled approvals, dependable supplier records, and regular reconciliation. Finance teams can strengthen results by assigning clear process ownership, using reports to manage exceptions, and connecting AP workflows with procurement and payment planning. Consistent review and targeted automation help improve transaction accuracy, supplier relationships, financial reporting, and cash flow visibility.
