Vendor registration: how to become an approved supplier

What vendor registration means

Vendor registration is how a company adds you to its list of approved suppliers. Once you are approved, you get a vendor code in its purchase system, and only then can it raise a purchase order and pay your bills. Large companies and public sector undertakings rarely buy from a supplier without one, however good the price.

Registration and approval are separate steps. Registration puts your details into the buyer's system. Approval, for anything that matters to the buyer's product or plant, comes after samples, checks and sometimes a visit to your unit. Learning how to become a vendor is mostly about getting through that second step.

Three routes: private companies, PSUs and government

• Private companies. Many large companies have a supplier registration page on their website or an online supplier portal, often built on systems such as SAP Ariba or Coupa. Mid-sized companies usually email a vendor registration form once the purchase team agrees to consider you.
• Public sector undertakings and railways. PSUs publish vendor enlistment notices and buy through their own e-procurement sites and the Central Public Procurement Portal. Indian Railways tenders on IREPS, and some safety-related railway items need vendor approval from RDSO. Government e-tender portals usually ask for a Class 3 digital signature certificate.
• Government departments. For goods and common services, central government buyers use the Government e-Marketplace. Our GeM registration guide for sellers takes you through it.

What vendor registration forms ask for

The basic papers are the same everywhere: GST, PAN, bank details, Udyam if you have it, and your catalogue and certificates. Our guide on how to reach purchase and procurement managers lists them. Larger buyers often add:

• a bank letter or cancelled cheque, so the account name can be matched with the name on your GST registration;
• a declaration of whether you are a micro, small or medium enterprise, because dues to micro and small suppliers carry special payment rules;
• quality certificates such as ISO 9001, and product approvals such as BIS where the item needs them;
• turnover or audited accounts for recent years, to judge whether you can handle their volumes;
• for service and labour contracts, your EPF and ESIC registrations and any labour licence, since buyers check that contract workers' dues are paid;
• signed declarations on their code of conduct, conflicts of interest and gifts, and sometimes a non-disclosure agreement.

Make a vendor pack: one PDF with a one-page profile, every certificate and registration, recent accounts and a covering letter, kept up to date. When a form arrives, you can fill it in from the pack the same day instead of searching for papers for a week.

How to become a vendor, step by step

1. Choose a short list of buyers. Ten companies that use what you make, close enough to supply reliably, are worth more than a hundred names. A packaging unit in Chakan might start with the auto-parts makers around it; a valve maker in Vadodara with the chemical plants in Ankleshwar and Dahej.
2. Find out how each one adds vendors. Look for a "Suppliers" or "Vendor registration" section on its website, then call the purchase department and ask what the process is for your item.
3. Submit the form complete, with every attachment. Incomplete forms tend to sit unprocessed rather than come back to you.
4. Follow up with the reference number. For example: "We submitted our vendor registration for corrugated boxes on 3 October, reference 4471. Is anything else needed for approval?"
5. Get through the evaluation. For anything that goes into their product, expect a sample, a trial order or an audit of your unit.
6. Get the vendor code in writing, and confirm who will send purchase orders and where invoices should go.

To build that short list of buyers, the Starleads list builder combines industries and cities in one Excel sheet, for example manufacturers in a few nearby industrial towns.

Staying on the approved vendor list

Approval is not permanent. Buyers review suppliers from time to time on delivery, rejections and price, and the weakest are dropped quietly. Tell every buyer at once when your bank account, GST registration or address changes, because a mismatch can hold up payments. Renew certificates before they expire, and send revised price lists to the purchase team rather than to users in the plant.

Fake vendor registration offers

A common fraud uses the names of well-known companies and PSUs. A call, email or website offers a large order or a vendor registration if you first pay a registration or security fee, often into a personal account. Before you pay anything:

• find the company's contact details on its official website yourself, and confirm the request through them;
• check that the email comes from the company's real domain, not a free email address or a look-alike name;
• never pay into an individual's bank account or UPI ID.

Questions people ask

Do I need a Udyam registration to become a vendor?

Usually not, but it helps. Many buyers record it, and public buyers give micro and small enterprises a procurement preference. Buyers can verify your Udyam number in seconds; our company search guide shows what they see.

How long does vendor approval take?

It depends on the buyer and the item. Office supplies may need only the registration form. A component for a vehicle or an ingredient for a medicine needs testing and audits, which take much longer. Ask the purchase team at the start what their process involves.

This is general information, not legal or tax advice. Each buyer sets its own vendor rules, and government portals publish their current requirements.
