Best Practices for the AP Approval Process in Business Central

Best Practices for the AP Approval Process in Business Central

Seven concrete controls that turn AP from a paper chase into an auditable, cash-flow-friendly machine.

Accounts Payable approval is the most-touched and most-ignored finance process in the mid-market. Done right, it controls cash, prevents fraud, and satisfies the auditor on day one. Done wrong, it costs the business 1–3% of revenue in duplicate payments, missed discounts, and unrecoverable VAT. Here are the seven best practices that change the picture inside Business Central.

1. Three-way match by default

Every supplier invoice matched to its PO and GRN before posting. Business Central ships with this — turn it on and enforce it for every supplier above a low-value threshold.

2. Approval workflow with amount + dimension routing

Route by amount, department, project, or vendor — not just by department head. Use BC native workflow or layer NOVAREQ-style multi-level approval on top.

3. Duplicate invoice detection

BC checks for duplicate supplier invoice number on entry. Make it a hard block, not a warning — duplicates are the single biggest cash leak.

4. VAT validation at posting

Every supplier invoice must carry a valid TRN, tax-compliant invoice number, and the correct UAE FTA or KSA ZATCA tax category. Block posting if any field is missing.

5. Capture early-payment discounts

Configure payment terms so 2/10 net 30 discounts are taken automatically. Most mid-market businesses leave 0.5–1% of supplier spend on the table.

6. Payment proposal with cash forecasting

Use BC's payment journal + cash flow forecast together — pay only what cash flow supports; don't strip the AR side to cover an over-aggressive AP run.

7. Continuous audit trail

Every approval, every change, every payment timestamped in BC's audit log. No separate audit module needed — and the external auditor can read it directly.

AP is a control function, not a clerical one

The mid-market default is to treat AP as a clerical job. It is not. AP is where the company spends the cash that the rest of the business earned — and the integrity of that spending defines the integrity of the books.

For UAE and KSA businesses preparing for FTA / ZATCA audits, AP discipline is the difference between a clean audit and a list of corrections.

"Every CFO has a war story about AP. The structural fix is unglamorous: workflow, three-way match, hard duplicate blocks. Done once, it pays back for ten years."
