Vendor registration pack: the documents a purchase team asks for, and how to read their list
Why a manufacturer should ask each buyer for its own vendor registration list before sending anything, how to translate the buyer's wording into documents you hold, and how to keep track of what each buyer has.

The purchase executive says "send your documents" and rings off. So you send the folder you sent the last buyer, and a week later an email lists five things missing, in words your folder does not use. Every vendor registration pack shares a core: GST, PAN, Udyam, bank proof, incorporation papers and a capability profile. But each purchase team adds its own extras, in its own words. Ask for their list first, fill it from one folder, and keep a log of what each buyer holds.
Ask for their list before you send anything
One call or email to the person who asked can save rounds of corrections. Ask for four things.
- Their registration form and document checklist, as a file. Not read out over the phone.
- The route: email to a named person, or a vendor portal, and any limits on file size or format.
- Which papers must be self-attested, signed by an authorised signatory, or printed on their format.
- What follows the papers. A works visit? A quality questionnaire? A sample?
A purchase team that sends its checklist has told you how your file will be judged. One that says "the usual documents" is telling you to send the core and wait for questions.
The core itself is covered in the note on getting on a company's approved vendor list, and plants and mines add their own layer in getting on plant and mine vendor lists. This post is about what sits on top of that core.
What their list says, and what it means
Buyers name the same paper differently, and some ask for papers you have never made. Read their checklist against this table before you reply. The last column is only a typical guide, since banks, advisers and partners vary.
| What the list says | What they want | Where it comes from | Ready today? (typically) |
|---|---|---|---|
| MSME certificate | Your Udyam registration certificate | The Udyam portal | Yes, if you are registered |
| Banker's or solvency certificate | A letter from your bank on your account, or on your standing up to a stated value | Your bank branch | No; the branch needs time |
| Turnover certificate | Turnover for named years, certified by a chartered accountant | Your CA | No; it needs the CA |
| Cancelled cheque | A cheque leaf with the firm's name printed, crossed and marked cancelled | Your cheque book | Yes |
| Authorisation letter or board resolution | Proof that the person signing may sign for the firm | Partners or directors | Same day, if they are in town |
| Non-blacklisting declaration | A signed statement, on their format, that no buyer or government body has blacklisted or debarred you | Their format, your signatory | Same day |
| Capacity statement | Machines, shifts and spare capacity for the parts they buy | Your production head | Yes, if the machine list is current |
| Process flow chart | The steps from raw material to dispatch, with inspection points, for their part family | Your quality person | Only if made before |
| Escalation matrix | Names and mobiles by role, and who to call when the first person does not answer | Your office | Yes |
| Related party declaration | Whether anyone at your firm is related to anyone at theirs | Their format | Same day |
The slow papers are the ones a bank or a CA must issue, and the ones a partner must sign while travelling. Request those the day the list arrives.
Keep a log of what each buyer holds
Once you are registered with three or four buyers, the hard question changes to "which version did we send to whom". A GST address amendment, a new bank account or a renewed certificate has to reach every buyer who holds the old one. Miss one, and the next payment stops at their accounts desk.
The log is one sheet with a row per buyer:
- Buyer, plant and vendor code, with the date it was created
- Portal or email route, and the office email that holds the login
- Every document sent, with its version or issue date
- Papers specific to that buyer: their code of conduct, NDA and declarations
- Their re-validation date, if they re-check vendors
- Your contacts in their purchase team and in their accounts
When anything in your folder changes, open the log and send the new version to every buyer on it. Keep their acknowledgement.
Imagine a rubber parts maker in Bhosari
Imagine a maker of rubber moulded parts in Bhosari, Pune: grommets, seals and bellows. Two buyers asked it to register in the same month, a tractor maker and a home appliance maker. The details are illustrative.
The owner sent both the same folder. The tractor maker's checklist, which the owner had not requested before sending the folder, listed a process flow chart for each part family and a capacity statement for the parts in its RFQ. The appliance maker wanted a solvency certificate and a non-blacklisting declaration on its own format. Both files came back with queries. The bank took longer over the certificate than the buyer's deadline allowed, and that RFQ went to a vendor already registered. The tractor maker's registration went through, and the appliance maker's lapsed.
A year later the unit moved its bank account. Accounts told the tractor maker. Nobody remembered the appliance maker's portal, whose login sat with an employee who had left, and the next payment went to the closed account and came back.
The office now asks for the checklist on the first call, reads it against the table above, and requests bank and CA papers that day. Every portal login now sits under one office email, a habit the post on moving a registration past each desk also asks for. A change of bank goes to every buyer in the log.
When one folder is not enough
Public sector buyers and large groups register through their own portals, with formats and validity rules that change, so read the current instructions before you upload. Buyers in aerospace and defence, railways and some regulated products ask for approvals that no folder replaces. Check with the buyer and your own adviser.
And a folder ages. Certificates lapse, a turnover certificate covers named years, and a solvency letter carries a date. A pack that passed last year can fail this year's re-validation, so check the dates before each new request rather than after the buyer does.
Start with the next request
The next time a purchase team says "send your documents", ask for their checklist before you attach anything, and start the bank and CA requests that day. Putting the capacity statement on your website too helps buyers who check you before they write; the manufacturing hub has more on that. If you want the folder and the log set up for your unit, with sales collateral development behind it, tell us what you need.
