What is a Vendor Registration?
A vendor registration form collects everything your organisation needs before it can pay a new supplier: legal name, registered address, tax registration, bank details and a contact who can answer questions. It matters because payment fails without it. A supplier who has delivered and invoiced but never registered sits in a queue while somebody chases a tax number, and the first payment run passes them by.
Procurement or accounts payable issues it; the supplier's finance or admin contact fills it in. It is used when onboarding any new payee — a new materials supplier, a contractor, a training provider, a landlord. Larger organisations run it alongside a due diligence pack: insurance certificates, quality accreditation, a signed code of conduct. Smaller ones use the same form as a single source of truth, so that the person raising the order, the person paying and the person filing the tax return are all working from the same details.
The fields you must collect are set by where you are. In India that means GSTIN, PAN and often a cancelled cheque for bank verification, plus MSME status if the supplier claims it, because payment timelines for micro and small enterprises are regulated. In the US it is normally a W-9 for domestic suppliers and a W-8 series form for foreign ones, driving 1099 reporting. In the EU and the UK, a VAT number, and for construction in the UK, CIS status. Check the current requirement with your accountant rather than copying another company's form.
Registration is not approval to trade. It sets a supplier up as a payee; whether they are approved to supply a particular category, and on what terms, is a separate decision that may need a quality assessment or an insurance check. It is also not a contract — the terms come from your purchase order or the agreement, and a supplier who signs the registration form has not accepted your trading terms unless the form says so and they have read them. And it is not a substitute for verifying bank details independently, which is the single control that stops payment diversion fraud.

How to write a Vendor Registration
Record the legal entity, not the trading name
Capture the registered legal name exactly as it appears on the company register, the entity type, the registration number and the registered office address. Trading as names go in a separate field. Payments and tax reporting run on the legal name, so a supplier registered under their brand will fail a bank name check and have the payment returned.
Collect tax registrations with evidence
Ask for the tax numbers your jurisdiction requires and for a document that shows them — a registration certificate, a tax form, a portal screenshot. A number typed into a box and never checked is a number that will be wrong at year end, when the mismatch surfaces in a return you have already filed.
Capture bank details and verify separately
Take the account name, number, sort code, IFSC, IBAN or routing number as your payment system needs it. Then verify by calling a number you already hold for that supplier — never a number printed on the form itself. Bank detail changes should follow the same verification, because the mid-invoice change of account email is the standard payment fraud.
Name a contact for each function
One person for orders, one for invoices and payment queries, one for escalation, each with a direct email and phone number. A single generic inbox is where chased invoices go to die. Add the supplier's own reference for your account, if they use one, so their finance team can find you without a phone call.
Set a review date and keep it current
Record who approved the registration and when, then diarise a review — annually is common — to reconfirm bank details, insurance expiry dates and contacts. Vendor master data decays quietly: companies are acquired, tax registrations change, contacts leave. Dormant records are also a fraud risk, so deactivate suppliers you have not used for a long period rather than leaving them live.
Common mistakes
- Accepting bank details from the form alone without an independent call-back, which is exactly how payment diversion fraud succeeds.
- Recording the trading name instead of the registered legal name, so payments fail a bank name check and tax reporting goes out under the wrong entity.
- Leaving the tax registration field blank to speed onboarding, which surfaces as an unrecoverable tax problem at year end.
- Treating registration as supplier approval, so a firm with lapsed insurance is sent onto site because someone saw them in the vendor list.
- Never reviewing dormant vendor records, leaving live payee accounts that nobody monitors and anybody could reactivate.
Frequently asked questions
What documents should I ask a new vendor for?
At minimum, proof of the legal entity, the tax registrations your jurisdiction requires, and bank details on the supplier's own letterhead or bank document. Depending on the work, add insurance certificates, licences, quality accreditation and a signed confidentiality or code of conduct. Ask your accountant which tax documents are mandatory where you operate before finalising the list.
Is a vendor registration form the same as vendor onboarding?
Registration is one step in onboarding. Onboarding also covers due diligence checks, approving the supplier for a category, agreeing terms, setting up systems access and, sometimes, a site visit. The form is the data collection part. Treating the completed form as the whole process is what puts unvetted suppliers into the approved list.
How do I verify a vendor's bank details safely?
Call the supplier on a number you already hold from an earlier document or their published website, never a number given on the registration form or in the email that carried it. Ask a person you have dealt with to confirm the account. Apply the same check to any later change of details, and treat urgency in the request as a warning sign.
Do small suppliers and sole traders need to register?
Yes, for the same reason — you still need their legal name, tax status and verified bank details to pay them correctly. What changes is the depth. A sole trader will not have a company registration number, and the tax fields differ. Be careful that engaging an individual does not create an employment or worker relationship; that test is a legal one and varies by country.
How long should vendor records be kept?
Long enough to satisfy tax and accounting record retention rules where you operate, which commonly run to several years after the last transaction — check the current period for your jurisdiction. Balance that against data protection obligations, since the form holds personal data for named contacts and, for sole traders, for the supplier themselves. Keep what you must and delete the rest on a schedule.
