Invoicing Guidelines & GST Compliance Requirements

Kochi Metro Rail Ltd (KMRL) requires vendors to submit GST-compliant invoices with proper documentation to ensure timely payment processing.

GST and Invoice Guidelines

GST Compliance: Invoices must indicate both the bidder’s GSTIN and KMRL’s GSTIN. KMRL reimburses GST at actuals based on the submitted invoice.
Contract Pricing: The total price should include all taxes, duties, insurance, freight, and labor. Prices are firm unless specified in the tender.
Proof of Compliance: Vendors must submit a copy of the latest filed GSTR1 return. Failure to comply can result in the recovery of denied input credit.
Documentation & Language: Invoices and technical bids must be in English. Supporting documents in other languages require certified translations.

Authorization

Only authorized persons with valid power of attorney or corporate board resolution can sign billing documents. Authorized dealers require a tender-specific manufacturer authorization letter.

Practical Steps for Efficient Payment

Ensure contract references and GSTINs are 100% accurate before submission.
2. Digital Upload
Submit copies via the GeM or relevant eProcurement portal as per instructions.
3. Attach Filings
Always include your latest GSTR1 return to avoid credit-related delays.
4. Track Milestones
Align invoice submission with LOA milestones or performance certificates.
