Vendor Compliance Management for Contractors and Suppliers
Vendor compliance means proving your contractors and suppliers follow GST, PF, ESI and wage rules. We build the checklist, collect proof every month and flag gaps before they become your liability.
What it is
Vendor compliance management is the monthly routine of proving that the people you pay follow the law. It covers the vendor’s own registrations, tax filings and, for labour contractors, wages and social security.
It matters because your liabilities do not end at the contract. The Labour Codes, GST rules and MSME payment rules all place duties on you as the buyer or principal employer. A vendor’s missed filing can become your denied credit, your disallowed expense or your unpaid wage claim.
Who it applies to
Companies using contract labour
Housekeeping, security, loading, canteen and factory staffing contractors. These carry the heaviest legal risk. Their workers stand on your premises, and the labour inspector will ask you first. See our contract labour licence guidance.
Manufacturers and traders buying on credit
Input tax credit depends on your suppliers filing returns. Payment timing matters too, especially with registered micro and small suppliers.
Growing firms with many small vendors
Once you have dozens of vendors, a spreadsheet and a good memory stop being enough. A Faridabad factory with 40 suppliers can lose credit simply because three of them filed late.
Why it matters
Protects your tax credit
Credit depends on the invoice reaching GSTR-2B and on payment within 180 days. A checked vendor list means no surprises at year end.
Limits labour exposure
Proof of PF, ESI and wage payment lets you pay a contractor with confidence. It also helps if an inspector visits.
Keeps expenses deductible
Payments to micro and small vendors beyond 45 days can shift the deduction to a later year. A due-date tracker prevents it.
What to check for each type of vendor
| Vendor type | What to verify | How often |
|---|---|---|
| Labour contractor | Licence, PF and ESI codes, challans, wage register, minimum wage compliance | Monthly |
| Goods supplier | GST registration status, GSTR-3B filing, invoice in GSTR-2B | Monthly or quarterly |
| Service provider | GST status, TDS deducted and deposited, contract in force | Quarterly |
| Micro or small enterprise | Udyam certificate, payment within 15 or 45 days | On every invoice |
Contract labour provisions under the OSH Code apply where 50 or more contract workers are engaged. Smaller contractors still owe PF, ESI and minimum wages where the Acts apply. PF applies at 20 or more employees and ESI at 10 or more. The EPF wage ceiling rose to ₹25,000 from 17 September 2026.
Documents required
At onboarding
- PAN, GST certificate and bank proof
- Udyam certificate, if the vendor claims MSME status
- Signed contract with a compliance clause
From labour contractors
- Contract labour licence and PF and ESI codes
- Monthly ECR and ESI challans
- Wage register and attendance records
From your side
- List of vendors with contract and payment dates
- Purchase register and GSTR-2B reconciliation
- Payment dates for MSME vendors
How it works
Map your vendors
We list every vendor, group them by type and mark which ones carry labour, tax or MSME risk. It takes a day or two, and it usually shows the gaps at once.
Collect proof and set the calendar
We gather onboarding papers and set monthly due dates for PF, ESI, GST and payment tracking.
Check each month and flag gaps
We review challans, GST filings and payment dates, and give you a short exceptions list. Where the law needs a qualified professional’s signature, that person signs.
Act on the exceptions
You decide whether to hold a payment, send a notice or change a vendor. We prepare the letters and update the tracker.
Timelines
Monthly dues
PF and ESI by the 15th of the next month, GSTR-3B by the 20th, and TDS deposit by the 7th.
MSME payments
Within 15 days without an agreement, and within 45 days at most with one.
MSME-1 return
Due 31 October for April to September and 30 April for October to March, for companies with overdue dues to micro or small suppliers.
What happens if a vendor defaults
Credit is denied or reversed
Missing invoices in GSTR-2B block credit. Unpaid invoices past 180 days require reversal with interest.
You may carry the labour liability
Unpaid contractor wages and social security can come back to you as principal employer.
Deduction moves a year
Late payment to a micro or small vendor shifts the deduction to the year of payment.
Frequently asked questions
What is vendor compliance management?
Vendor compliance management is the routine of checking that every vendor and contractor you pay follows the laws that touch you: GST, PF, ESI, minimum wages, MSME payment rules and licences. You collect proof before onboarding and every month after. We build the checklist, collect the documents, flag gaps and report to you. A qualified professional signs where the law needs a signature.
Am I liable if my contractor does not pay PF or ESI?
You can be exposed. The old Contract Labour Act made the principal employer pay unpaid wages and recover the amount from the contractor, and PF and ESI authorities can also look to the principal employer when a contractor defaults. The safe practice is to hold payment until you see proof of the monthly PF and ESI deposits.
How does a vendor’s GST default affect my input tax credit?
You can claim input credit only if the invoice appears in your GSTR-2B, and the supplier has to file for that. Credit must also be claimed by 30 November after the financial year ends, or the annual return date, if earlier. If you do not pay the supplier within 180 days, the credit is reversed with interest. Track both dates.
What is the 45-day rule for paying MSME vendors?
If a vendor is a registered micro or small enterprise, you must pay within the agreed time, which is 15 days without a written agreement and 45 days at most with one. If you miss it, the deduction moves to the year you actually pay. It was Section 43B(h) of the 1961 Act, and is Section 37(2)(g) of the Income-tax Act 2025 from tax year 2026-27.
Do I need a contract labour licence for my contractors?
It depends on headcount. Under the OSH Code, in force from 21 November 2025, the contract labour provisions apply where 50 or more contract workers are engaged on any day in the previous year, while an establishment with 10 or more workers must register. Our contract labour licence page explains the details.
What documents should I collect from a new vendor?
Collect PAN, GST registration certificate, Udyam certificate if claimed, bank proof, a signed contract and, for labour contractors, PF and ESI codes and licences. After onboarding, ask for the monthly challans and the wage register. We keep these in one tracker so you can find any vendor’s papers in seconds.
How often should vendor compliance be checked?
Monthly for vendors who supply labour or run payroll, and quarterly for pure goods suppliers. PF and ESI are due by the 15th of the next month, GST returns by the 20th for GSTR-3B, and TDS deposits by the 7th, so a check in the second half of the month catches missed deposits. The cadence is set when we agree the plan.
What if a vendor refuses to share compliance proof?
A refusal is itself information. You can hold the payment as per your contract, ask for a corrective plan, or replace the vendor. We help you add a compliance clause to the agreement so that withholding payment has a clear contractual basis, and your advocate vets the wording.
What it costs
Our fee plus the government fee that applies to your case, quoted before you commit. Tell us the situation and we will price it exactly.
There is no government fee for running a vendor compliance programme. Government fees arise only for registrations, such as a licence or PF and ESI codes, and for any statutory filing. We list these separately in the quote.
