A structured and compliant vendor onboarding process is critical to avoiding payment delays, fraud risks, and compliance issues. Whether you’re a finance pro, AP specialist, or small business owner, here’s your must-have checklist for new vendor approval and setup:
📌 Step 1: Structured Vendor Setup Request & Approval Process
✔️ Implement a formal vendor setup request form or workflow
➡️ Note: The vendor request process can be a form or a workflow like a ticketing process—I’ve used both. I prefer an electronic ticketing process for efficiency and tracking, but the key is to have a standardized approach that ensures consistency and accountability.
✔️ Require department head and finance approvals before initiating setup
✔️ Clearly define approval criteria (business need, budget, risk assessment)
✔️ Assign responsibilities to ensure checks and balances in the process
🔍 Step 2: Vendor Documentation Collection
✔️ Completed vendor application form
✔️ W-9 (US vendors) / W-8BEN (foreign vendors) for tax compliance
✔️ Business license, insurance certificates (if required)
✔️ NDA or contract agreement (if applicable)
💳 Step 3: Secure Payment Method Verification (Segregated Process)
🚨 Important: Payment verification should be conducted separately from vendor setup to prevent fraud.
✔️ Independently verify banking details (e.g., call a known contact, verify letterhead, use secure portals)
✔️ Confirm payment instructions with a secondary source
✔️ Require a test transaction (if necessary) before approving full payments
💻 Step 4: Vendor Setup in the System
✔️ Assign unique vendor ID in accounting system
✔️ Input tax details and payment terms
✔️ Set up approval workflows and payment methods (only after independent verification!)
✔️ Include payment instructions and collected documents (e.g., W-9 or W-8BEN) as permanent records for audit and compliance
✅ Step 5: Final Compliance & Communication
✔️ Ensure all required approvals are obtained
✔️ Notify internal stakeholders (procurement, finance, operations)
✔️ Provide vendor with payment schedule & policies
🎯 Bonus Step: Don’t Be Afraid to Reject a Request!
🚨 Not every vendor request should be approved. If something doesn’t add up, if the information is incomplete, or if there are already too many vendors of the same type—question it. If necessary, reject it.
✔️ Ensure accuracy before approval—cutting corners leads to compliance risks
✔️ Push back when necessary—AP is not just a data-entry function, it’s a financial control
✔️ Fraud prevention starts with vendor scrutiny—if a request seems suspicious, investigate further
