Vendor Evaluation Checklist for Plant Managers India — 2026 Guide
A structured vendor evaluation checklist for Indian plant managers covering technical capability, commercial terms, GST and compliance, financial stability, and after-sales support — with a scoring matrix.
Most industrial procurement failures in India are not caused by choosing the wrong product — they are caused by choosing the wrong vendor. A technically correct pump from a financially unstable vendor with no local service support becomes a liability within 18 months.
This vendor evaluation checklist gives plant managers and procurement teams a structured framework to assess industrial suppliers before onboarding. It covers five dimensions: technical capability, commercial reliability, regulatory compliance, financial stability, and after-sales support.
Dimension 1: Technical Capability
Assess whether the vendor can deliver what your plant actually needs, not just what they claim in their brochure:
- Product range and specifications — does the vendor's catalogue cover your duty requirements (flow, head, power, temperature, pressure)?
- Manufacturing or stocking capability — for standard items, do they hold stock? For custom items, do they have in-house manufacturing?
- Testing capability — for capital equipment, can they perform and document factory acceptance tests (FAT)?
- Engineering support — can they provide selection calculations, application engineering, or installation guidance?
- Application references — how many similar installations have they completed in your industry and your geographic region?
- Technical documentation quality — are their GA drawings, performance curves, and data sheets complete, legible, and in IS/metric units?
Dimension 2: Regulatory and Compliance
Non-compliance with statutory requirements blocks your payments, audits, and insurance claims. Verify:
- GSTIN — verify on gst.gov.in; check that the GSTIN is active and the address matches the operating address
- PAN card — required for TDS deduction above ₹30,000 per financial year for services, ₹1 lakh for goods
- MSME/Udyam registration — relevant if the vendor claims MSME benefits or if your plant has MSME procurement targets
- ISO 9001 certification — mandatory for many plant procurement departments; check validity date and issuing body accreditation
- Industry-specific certifications — IBR approval for boiler fittings and pressure vessels, BIS certification for electrical equipment, PESO approval for hazardous area equipment
- Pollution and labour compliance — valid pollution under control certificate, ESI and PF registration for vendors deploying labour at your site
Dimension 3: Commercial Reliability
A vendor who delivers late or invoices incorrectly creates downstream problems in your planning and accounts payable. Assess:
- Delivery track record — ask for on-time delivery percentage from their existing customers; target above 85%
- Quoting quality — are their quotations complete, unambiguous, and comparable with others? Vague quotes signal future disputes
- Invoice accuracy — do their invoices match the PO exactly on quantity, description, HSN code, GST rate, and amount?
- Payment terms flexibility — can they offer standard terms (30/45/60 days credit) or do they require advance payment for every order?
- Return and warranty handling — what is the process and lead time for warranty claims and return of defective goods?
Dimension 4: Financial Stability
A vendor who goes bankrupt or faces financial stress mid-order leaves your project stalled with no recourse. For orders above ₹5 lakh, verify:
- Bank reference — ask the vendor to provide a letter from their banker confirming the account relationship and credit facilities
- Trade references — request 2–3 references from current customers of similar order value; call and confirm
- GST return filing — vendors with regular GST filings (check on the GST portal) demonstrate operational continuity
- CIBIL or credit report — for large suppliers, commercial credit bureaus provide formal business credit scores
- Years in operation — vendors established more than 5 years with a consistent customer base present lower delivery risk
Dimension 5: After-Sales Support
For capital equipment and maintenance-intensive items, after-sales support is as important as the initial supply. Verify:
- Service engineers in your region — the vendor must have trained technicians within a reasonable travel distance of your plant
- Spare parts availability — critical wear parts (seals, bearings, impellers) must be stocked locally or available within 1–2 weeks
- AMC (Annual Maintenance Contract) capability — can they offer a structured AMC for critical equipment?
- Response time commitment — for breakdowns, what is their guaranteed response time? Get it in writing.
- Technical helpline — is there a reachable number for technical guidance during a breakdown?
Vendor Scoring Matrix
Use this scoring matrix to compare vendors objectively. Score each vendor 1–5 on each criterion, weight by importance for your plant, and select the highest weighted score — not necessarily the lowest price.
| Criterion | Weight | Max Score | Notes |
|---|---|---|---|
| Technical capability | 25% | 5 | Application references, testing, engineering support |
| Regulatory compliance | 20% | 5 | GSTIN, ISO, industry certifications |
| Delivery reliability | 20% | 5 | OTD track record, lead time accuracy |
| After-sales support | 20% | 5 | Regional presence, spare parts, response time |
| Commercial terms | 10% | 5 | Payment terms, quoting quality, invoice accuracy |
| Financial stability | 5% | 5 | Bank reference, years of operation, GST filings |

Frequently Asked Questions
What are the most important criteria for evaluating industrial vendors in India?
The five most critical: (1) GSTIN and ISO 9001 compliance — without these you cannot claim input tax credit or meet quality audit requirements. (2) Application-specific experience — ask for references at similar plants. (3) Regional after-sales support — a vendor with no local service presence is a liability for capital equipment. (4) On-time delivery track record — ask for OTD % from existing customers. (5) Financial stability — for large orders, check bank references and GST filing regularity.
How do I check if a vendor is GST compliant?
Visit gst.gov.in → Search Taxpayer → enter the vendor's GSTIN. Verify: (a) registration status is "Active", (b) the legal name and state match what the vendor has provided, (c) the filing history shows returns submitted up to date (no long gaps). Also check on the GST portal whether the vendor has filed GSTR-3B for the last 6 months — gaps indicate cash flow problems or compliance issues.
Should I require ISO 9001 from all vendors?
For critical equipment, capital items, and safety-related supplies — yes, ISO 9001 (or relevant product-specific certification such as IBR, PESO, BIS) should be mandatory. For commodity supplies and general consumables, ISO 9001 is good to have but not always necessary. Prioritise it where product quality directly affects your plant safety, product quality, or regulatory compliance.
How many vendors should I shortlist before requesting formal quotations?
Best practice is 3–5 vendors for each requirement. Fewer than 3 limits price competition; more than 5 creates unnecessary evaluation load. For strategic/recurring purchases (annual rate contracts), shortlist 2–3 after full evaluation. For one-off capital items, 3–4 qualified vendors provides sufficient competition. Always have a second approved vendor for critical items to avoid single-source dependency.
How can I reduce the time spent on vendor evaluation?
Three approaches: (1) Use an industrial marketplace where vendors are pre-screened for GSTIN, certifications, and service coverage before being allowed to apply. (2) Develop a standard Vendor Qualification Form (VQF) that captures all evaluation criteria in one document — send it to all potential vendors upfront. (3) Build an Approved Vendor List (AVL) for recurring categories so you only re-evaluate periodically, not for every order.
