How do I ensure my bill pay support workflow with AP bookkeeping is compliant with approval routing requirements?

To keep a bill pay support workflow with AP bookkeeping compliant with approval routing requirements, focus on clear controls, documented approvals, segregation of duties, and auditability.

Key practices

1. Define approval rules up front

Create a policy that specifies:

• Who can approve what
• Approval thresholds by amount
• Extra approvals for exceptions, urgent payments, new vendors, or manual payments
• Who routes and who cannot self-approve

Example:

• Under $1,000: AP manager approval
• $1,000–$10,000: department head + AP manager
• Over $10,000: CFO approval
• New vendors or bank detail changes: added review by Finance Ops or Compliance

2. Separate duties

Make sure no single person can:

• create the vendor
• enter the bill
• approve the bill
• release the payment
• reconcile the transaction

At minimum, separate:

• Requesting/initiating
• Approving
• Recording in books
• Paying/releasing funds
• Reconciling

3. Use a formal routing workflow

Your system or process should automatically route bills based on:

• amount
• vendor risk
• GL account/category
• cost center
• payment type
• exception flags

If the system can’t route automatically, document a manual fallback with timestamped evidence.

4. Maintain approval evidence

For every bill, retain:

• invoice copy
• approval record
• approver name
• approval date/time
• reason for approval if exception
• related support docs/POs/receipts/contracts
• payment confirmation

Use a system with immutable logs if possible.

5. Enforce PO/3-way matching where applicable

For purchase orders and inventory/receipts:

• PO
• receiving document
• invoice

Require matching before approval or payment, unless a documented exception applies.

6. Control exceptions tightly

Define how to handle:

• urgent payments
• duplicates
• credits
• missing PO
• non-PO invoices
• manual check/wire requests

Every exception should require:

• documented rationale
• higher-level approval
• review after the fact if necessary

7. Restrict vendor master changes

Since bill pay fraud often starts with vendor changes:

• require dual approval for new vendors and bank updates
• validate tax forms and banking information independently
• log all changes
• review vendor master periodically

8. Reconcile regularly

Perform:

• daily/weekly payment review
• monthly AP subledger to GL reconciliation
• bank reconciliation
• review of aged/unapplied credits and duplicate payments

9. Train staff and document procedures

Create SOPs for:

• bill entry
• approval routing
• exceptions
• escalation paths
• handling missing support

Then train AP staff and approvers so routing is consistent.

10. Periodically test compliance

Run internal checks for:

• approvals missing or out of order
• approvers approving their own requests
• payments made before approval
• duplicate invoices
• manual overrides
• unauthorized vendor edits

Practical control checklist

A compliant workflow should answer “yes” to these:

• Is every bill tied to an approved request, PO, or documented support?
• Are approval thresholds defined and enforced?
• Are approvals captured before payment?
• Is there segregation between entry, approval, and payment?
• Are exceptions documented and escalated?
• Are vendor changes controlled?
• Are audit logs retained?
• Are reconciliations performed regularly?

Suggested policy language

“All invoices must be reviewed and approved in accordance with the approved authorization matrix prior to payment. AP may record invoices but may not approve invoices or initiate payments without appropriate documented authorization. Exceptions require documented justification and secondary approval.”
