Introduction
Of all the documents in an export shipment, the commercial invoice is the one that does the most work. It is your bill to the buyer, your customs declaration to Indian authorities, your compliance document under GST, your reference point for the bank processing your payment, the basis for your buyer's import duty calculation at their end, and the foundation against which every other document in the shipment set is checked for consistency.
Get the invoice right and everything else in the shipment has a solid anchor. Get it wrong — even a small error in the value, a missing field, a GST declaration that does not match your Shipping Bill, or an invoice number that violates GST formatting rules — and the consequences cascade: customs queries, LC discrepancies, payment delays, IGST refund blocks, and in the worst case, shipment detention at the destination.
I have reviewed hundreds of export invoices from new exporters over the years, and the errors I see most consistently are not random — they are the same categories of mistakes made by people who did not know what a fully compliant export invoice looks like. This guide fixes that. I will walk you through every mandatory field, explain exactly why each one is required, show you how the GST compliance requirements apply to export invoices, and give you a complete sample template you can use and adapt.
The Export Invoice Is Two Documents in One
Before we go through the fields, understand this fundamental point: your export commercial invoice is simultaneously a commercial document (the billing instrument between you and your buyer) and a GST tax invoice (the statutory tax document under the CGST Act). It must satisfy the requirements of both.
As a commercial document, it must contain all the information the buyer, their bank, and their customs authority need to process the transaction. As a GST tax invoice, it must comply with Rule 46 of the CGST Rules — including mandatory fields, sequential numbering, and the specific GST declaration for zero-rated exports.
This dual nature is what makes export invoices slightly more complex than a standard domestic sales invoice. You are not just billing a customer — you are creating a document that must navigate two regulatory systems simultaneously.
Proforma Invoice vs Commercial Invoice: The Difference
Many exporters use these terms interchangeably, which is a mistake. They are different documents with different purposes and different compliance requirements.
A Proforma Invoice is issued before the order is confirmed. It is your price quotation in invoice format. The buyer uses it to open a Letter of Credit at their bank, to apply for an import licence in their country, or simply to assess your offer. A Proforma Invoice is NOT a GST tax invoice — it does not create any tax liability, and it does not need to comply with GST invoice rules. It does not have a sequential invoice number in the GST system sense.
A Commercial Invoice (also called the Tax Invoice for export purposes) is issued at the time of or after shipment. This is the actual billing document. It IS a GST tax invoice and must comply fully with Rule 46 of the CGST Rules. It carries a sequential invoice number, a GST declaration, and all the mandatory fields we will cover below.
For the purposes of this guide, everything that follows refers to the Commercial Invoice / Tax Invoice — the document you issue for actual export shipments.
GST Invoice Rules for Exports: The Legal Foundation
Before listing the mandatory fields, let us establish the legal basis for export invoice requirements.
Under the CGST Act and CGST Rules, exports are zero-rated supplies. For zero-rated supplies made under LUT (Letter of Undertaking), the exporter issues a tax invoice and exports without charging IGST. For zero-rated supplies with IGST payment, the invoice shows the IGST amount.
Rule 46 of the CGST Rules lists the mandatory particulars for a tax invoice. For exports, additional fields are required beyond the standard domestic invoice requirements. The invoice must also comply with any special requirements of the destination country and, where applicable, the LC terms.
E-Invoicing Note for 2026: If your annual aggregate turnover exceeds ₹5 crore, your export invoices must be generated on the government's Invoice Registration Portal (IRP) and carry an IRN (Invoice Reference Number) and QR code. The IRP auto-populates your GSTR-1 with the invoice data, which simplifies the export reporting process. If you are above this threshold and not yet generating e-invoices, you are non-compliant — rectify this immediately.
Mandatory Fields on an Export Commercial Invoice
I have organised these fields into logical groups — not just a flat list — because understanding the category helps you understand why each field exists and what system it feeds.
Group 1: Your Identification (Exporter Details)
Legal Name of Exporter
Your full legal business name exactly as registered with GST and MCA/Registrar of Firms. Not your trade name, not an abbreviation. If your GST registration shows "Acme Exports Private Limited," that is what appears on the invoice — not "Acme Exports" or "Acme Exports Pvt Ltd."
Registered Business Address
Complete address including pincode. Must match your GST registration address. Customs authorities, banks, and destination country customs use this for verification. If your address has changed and you have not updated your GST registration, update it first — then use the updated address.
GSTIN (GST Identification Number)
Mandatory on every tax invoice. This is the 15-character alphanumeric GSTIN issued when you registered for GST. This links your invoice to your GST profile and enables matching with your GSTR-1 returns and Shipping Bill data for refund processing.
IEC (Importer Exporter Code)
Your 10-digit IEC issued by DGFT. While not a GST requirement per se, it is a standard export invoice requirement — your CHA needs it for the Shipping Bill, banks need it for FEMA compliance, and buyers increasingly expect it as a credibility indicator. Include it on every export invoice.
PAN (Permanent Account Number)
Recommended (sometimes required by certain markets or LC terms). The PAN links your export business to your direct tax profile.
Contact Details
Email address, phone number, and website. Not legally mandatory under GST Rule 46, but practically required — this is how your buyer, bank, and freight forwarder contact you about shipment issues.
Group 2: Buyer Identification (Consignee / Buyer Details)
Buyer's Full Legal Name
The complete legal name of the entity buying your goods. For LC transactions, this must exactly match the LC applicant name. For direct T/T transactions, it must match the buyer's official business registration name.
Buyer's Complete Address
Full address including city, country, and postal code. Required for customs clearance in the buyer's country and for FEMA's export proceeds realisation tracking.
Buyer's VAT/Tax Number
Many countries require or strongly prefer the importer's VAT or tax registration number on import invoices. For the EU, the EORI (Economic Operator Registration and Identification) number is particularly important. For the USA, it is not always on the commercial invoice but the buyer's IRS/EIN number may be needed for certain products. Check destination-specific requirements with your buyer.
Group 3: Invoice Reference Details
Invoice Number
Under GST Rule 46, the invoice number must be sequential, consecutive, unique within the financial year, and must not exceed 16 characters. You can use letters, numerals, and hyphens/slashes. Examples of valid formats:
- EXP/2026-27/0001
- INV-26-001
- ACME/EXP/26/001
Common mistakes: restarting the number sequence mid-year, using the same number for two invoices, using more than 16 characters, using special characters other than hyphen/slash. The sequential numbering must not have gaps — if you void an invoice, document the void but do not reuse the number.
Invoice Date
The date on which the invoice is issued. This date is the reference point for GST return filing (the month in which this invoice appears in your GSTR-1), for the LC presentation period calculation (days run from the B/L date, but the invoice date must fall within the shipment period), and for FEMA export realisation timelines (the 9-month clock for receiving export proceeds may reference this date for service invoices).
Purchase Order (PO) Number
The buyer's purchase order reference number. Not a GST requirement but practically essential — your buyer's accounts payable team matches your invoice against their PO for payment processing. A missing PO reference delays payment even after all documents are compliant.
LC Number and Date
If the payment is under Letter of Credit, the LC number must appear on the invoice. Under UCP 600 Article 18, the invoice need not explicitly reference the LC — but in practice, LC terms almost always require the LC number on the invoice, and its absence is a common discrepancy reason.
Group 4: Shipment Details
Port of Loading
The Indian port from which the goods are being shipped. "JNPT, Mumbai" or "Mundra Port, Gujarat" or "Chennai Port, Tamil Nadu." This must match what your CHA enters on the Shipping Bill.
Port of Discharge / Final Destination
The destination port and/or final delivery city and country. "Hamburg, Germany" or "Port of Los Angeles, USA" or "Jebel Ali, Dubai, UAE." Must align with the Bill of Lading.
Country of Final Destination
The country where the goods will ultimately be used or consumed. Relevant when goods are shipped to an intermediate port or distribution hub before onward movement.
Incoterms
Specify the applicable Incoterm in full with the port name and Incoterms version year: "FOB JNPT, Incoterms 2020" or "CIF Hamburg, Incoterms 2020." Never just write "FOB" without the named place and version — it is commercially incomplete and creates ambiguity.
Mode of Transport
Sea / Air / Road. Useful for freight forwarders and destination customs to direct the shipment to the appropriate handling process.
Vessel Name and Voyage Number (post-shipment)
Added after the goods are loaded. Some exporters issue the invoice pre-shipment (when booking) and add the vessel details in an amended or supplementary line. Others issue the invoice only after the vessel departs and the B/L is available. Either approach is acceptable.
Bill of Lading Number and Date (post-shipment)
The B/L number from the shipping line. Added after issuance of the B/L. Required for LC document presentation (the bank checks that the B/L referenced in the invoice exists and matches). Also required by destination customs in many countries.
Group 5: Product Details
Description of Goods
This is one of the most critical fields and one of the most commonly mishandled. The description must be:
- Specific enough to allow classification under the correct HS code
- Consistent with the HS code you declare
- Consistent with the LC product description if payment is under LC (must correspond to the LC wording, though need not be identical word-for-word)
- Not so vague as to invite customs examination at the destination (writing "General Merchandise" or "Various Goods" is a red flag for customs everywhere)
Good example: "Turmeric Powder (Curcumin 3.5% min), Organic, NPOP Certified, Net weight 500g/bag"
Bad example: "Spices" or "Agricultural Products"
ITC-HS Code (8-digit)
The full 8-digit ITC-HS Code for the product. Required on the Shipping Bill and standard practice on the commercial invoice. This is the primary reference for customs classification on both ends. Use the same code consistently across all documents.
HSN Code (for GST invoice compliance)
The 4 or 6-digit HSN code (first 4 or 6 digits of the ITC-HS code) for the GST invoice. For exporters with turnover above ₹5 crore, 6-digit HSN is mandatory. In practice, use the full 8-digit ITC-HS code — it satisfies both the GST HSN requirement and the customs HS code requirement simultaneously.
Country of Origin
"Made in India" or "India" or "Country of Origin: India." Required in most export transactions as it determines the applicable duty rate in the importing country, particularly when FTA benefits are being claimed.
Quantity
Number of units and the unit of measurement. Be precise: "1,000 kg" not "approx. 1 MT." The exact quantity must match the packing list and the Shipping Bill. Any discrepancy across these three documents creates customs questions on both ends.
Unit Price
Price per unit of measurement in the agreed foreign currency. "USD 5.00 per kg" or "EUR 120.00 per piece."
Total Line Value
Quantity × Unit Price for each line item. If you have multiple products on one invoice, each line should show the line total.
Total Invoice Value
Sum of all line item values. Show in both figures and words — "USD 5,000.00 (United States Dollars Five Thousand Only)." The words format is required by many banks for LC document checking and prevents disputes about numeral interpretation.
Group 6: Financial Details
Currency of Invoice
The foreign currency in which the transaction is denominated. USD, EUR, GBP, AED, etc. Under FEMA, export invoices should be in freely convertible foreign currency unless RBI has specifically permitted INR settlement for that country or transaction type.
Exchange Rate (for INR equivalent)
Not always shown on the commercial invoice itself, but required for Shipping Bill purposes. Indian customs declares the FOB value in both USD (or the invoice currency) and INR. The RBI reference rate (or CBEC notified exchange rate) on the Shipping Bill filing date is used. Your CHA handles this conversion — but you should know the mechanics so you can verify the Shipping Bill FOB value in INR matches reasonable expectations.
Payment Terms
State the agreed payment terms clearly: "100% advance T/T before shipment," "Sight LC," "60 days after B/L date," "50% advance, balance against documents." This is important for your bank's FEMA compliance check — they verify that export proceeds arrive within the terms and within the 9-month FEMA deadline.
Bank Details (for T/T payment)
If payment is by wire transfer (T/T), include your complete bank details on the invoice:
- Bank name and branch name
- Account name (exactly as the account is registered)
- Account number
- IFSC code
- SWIFT / BIC code
- Bank branch address
For LC payments, do not include bank details on the invoice — payment flows through the LC mechanism, not by wire transfer to your account.
Group 7: GST Declaration (The Most Important Field Most Exporters Get Wrong)
This is the field that distinguishes an export invoice from a domestic invoice and that is most frequently missing or incorrect.
Your invoice must explicitly declare the GST treatment of the export. There are two versions depending on your export route:
If exporting under LUT (recommended route):
"Supply Meant for Export Under Letter of Undertaking Without Payment of Integrated Tax.
LUT ARN: [Your current financial year LUT ARN number]"
If paying IGST on export (Route 2):
"Supply Meant for Export on Payment of Integrated Tax.
IGST Rate: [Rate]%
IGST Amount: [Amount in INR]"
This declaration is legally required under the GST rules for export invoices. It is also how your GSTR-1 filing and Shipping Bill are cross-checked for consistency. If your invoice says "LUT" but your Shipping Bill says "IGST Paid," you have an inconsistency that can block your GST refund. If your invoice says "IGST Paid" but you did not actually pay IGST, you have a false declaration — a serious compliance issue.
Common mistake: Many exporters simply leave out the GST declaration entirely, treating the export invoice like a domestic invoice without a tax line. This makes the invoice technically non-compliant and can be raised as a deficiency during any GST audit or refund examination.
Group 8: Signatures and Certification
Authorised Signatory's Signature and Name
The invoice must be signed by an authorised representative of your business. For companies, this is typically a director or officer with signing authority. The name and designation of the signatory should appear below the signature.
Company Stamp / Seal
While not a strict legal requirement under GST, a company rubber stamp on the invoice is standard practice in Indian export trade and is expected by buyers, banks, and many destination customs authorities. Always use your stamp.
Declaration (optional but recommended)
Many exporters include a declaration at the bottom: "We declare that this invoice shows the actual price of the goods described and that all particulars are true and correct." This mirrors standard international trade practice and can be required by some LC terms or destination country customs.
Invoice Copies: How Many Do You Need?
The number of invoice copies required depends on the payment method and destination requirements:
- Standard T/T payment, sea freight: Original + 3 copies is typical. One for customs (via CHA for Shipping Bill), one for the buyer, one for your CHA's records, one for your own file.
- Under LC: The LC specifies exactly how many originals and copies are required — commonly "3 originals and 2 copies." Follow the LC specification precisely. Presenting fewer originals than the LC requires is a discrepancy.
- E-invoices (for businesses above ₹5 crore turnover): The IRP-generated e-invoice with IRN is the primary document. Physical copies are generated from this.

Invoice vs Proforma Invoice: A Side-by-Side Comparison
Since the confusion between these two documents is so common, here is a clear summary:
- Purpose: Proforma = pre-order quotation | Commercial Invoice = post-order billing
- GST compliance: Proforma = not required | Commercial Invoice = mandatory
- Invoice number (sequential): Proforma = no | Commercial Invoice = yes, mandatory
- GST declaration: Proforma = not required | Commercial Invoice = mandatory
- Creates tax liability: Proforma = no | Commercial Invoice = establishes zero-rated supply record
- Used for customs clearance: Proforma = no | Commercial Invoice = yes
- Used for LC payment: Proforma = to open LC | Commercial Invoice = to claim payment
- Used for GSTR-1 reporting: Proforma = no | Commercial Invoice = yes
Currency, Value, and the Exchange Rate Question
Export invoices are issued in foreign currency — USD, EUR, GBP, AED, or whichever currency you and the buyer have agreed. However, Indian customs and GST systems work in INR. Your CHA will declare the FOB value on the Shipping Bill in both the invoice currency and in INR, using the exchange rate prescribed by CBIC (published weekly). This converted INR value is what customs uses for statistical purposes and what flows into RoDTEP and Drawback calculations.
You do not need to show the INR equivalent on your commercial invoice — the CHA handles that on the Shipping Bill. What you must ensure is that your invoice value (FOB portion, if you are quoting CIF) is clearly stated so the CHA can accurately calculate the FOB value for the Shipping Bill.
If you are quoting CIF and your invoice shows a single CIF price without separately itemising freight and insurance, instruct your CHA on the approximate freight and insurance component so they can deduct it accurately to arrive at FOB for the Shipping Bill. Alternatively, show the breakdown on the invoice: "Goods value (FOB): USD 9,000 + Freight: USD 500 + Insurance: USD 30 = CIF Total: USD 9,530." This transparency prevents any ambiguity.
Common Export Invoice Errors and How to Fix Them
These are the errors that appear most frequently in the invoices I review — each one has a specific consequence if left unfixed.
Missing GSTIN. Without GSTIN, the invoice is not a valid GST tax invoice. Your GSTR-1 will not match, your bank will have compliance questions, and your buyer may face import complications in countries that require the exporter's tax number. Fix: always include your GSTIN, formatted exactly as issued (15 characters, beginning with your state code).
Missing LUT declaration or wrong ARN. Exporting under LUT but the invoice either has no GST declaration or references an old year's LUT ARN. The Shipping Bill will show LUT route, but your invoice does not corroborate it — creating a document inconsistency that affects refund processing. Fix: verify your current financial year LUT ARN and include it on every LUT-route export invoice.
Invoice value inconsistent with Shipping Bill FOB value. Your invoice shows USD 10,000 but your CHA enters the Shipping Bill at a different FOB value — because they adjusted for freight or insurance without your knowledge. Fix: always review the Shipping Bill draft before it is filed. Confirm that the FOB value on the Shipping Bill matches your invoice (or the FOB portion of your CIF invoice if applicable).
Invoice number exceeds 16 characters or has gaps. A 17-character invoice number violates GST Rule 46. A gap in sequential numbering creates compliance questions. Fix: design your invoice numbering system to stay within 16 characters, and never reuse or skip numbers within a financial year.
Vague product description. "General merchandise," "Spices," "Engineering goods" — descriptions that do not allow customs to verify the HS code classification. Destination customs may flag the shipment for examination. Fix: write specific, complete product descriptions that directly correspond to and justify the stated HS code.
Different Incoterms than what was agreed. Your contract says FOB but your invoice says CIF — because a junior team member prepared the invoice without checking the contract. This creates confusion about who is responsible for freight and insurance. Fix: always pull the Incoterms from the signed purchase order or LC and use exactly the same term on the invoice.
Wrong or missing bank details. Your invoice has outdated bank details — an old account you no longer use or a branch that has changed its IFSC due to bank merger. Your buyer's T/T payment goes to the wrong account or bounces back. Fix: verify bank details on the invoice template every time you update your banking arrangements.
HS Code on invoice does not match Shipping Bill. Your invoice shows one HS Code (entered manually) and your CHA enters a different one on the Shipping Bill. Causes GSTR-1 vs Shipping Bill mismatch, destination customs inconsistency, and incentive rate calculation errors. Fix: agree on the exact 8-digit HS code with your CHA before the season begins, include it on your invoice template, and verify the Shipping Bill carries the same code.
E-Invoicing for Exporters: What Changes
If your aggregate annual turnover exceeds ₹5 crore, you are in the mandatory e-invoicing bracket. Here is how e-invoicing changes your export invoice workflow:
- You prepare the invoice in your accounting software or ERP (Tally, Zoho Books, SAP, Busy, etc.)
- The software sends the invoice data to the Invoice Registration Portal (IRP) via API
- The IRP validates the data, generates an IRN (Invoice Reference Number — a 64-character hash), and returns a digitally signed JSON with the IRN and QR code
- Your software embeds the IRN and QR code on the printed invoice
- The IRP automatically pushes the invoice data to GSTR-1 (Part A1) — eliminating the manual data entry step for your return filing
For export invoices, the e-invoice system supports the zero-rated export classification. When you generate an export e-invoice, select the supply type as "Exports" and indicate whether it is "With Payment of IGST" or "Without Payment of IGST (LUT)." The IRN and QR code make the invoice tamper-evident and digitally verifiable.
Importantly, even for e-invoices, all the mandatory fields discussed in this guide remain applicable — e-invoicing does not reduce the content requirements; it adds a layer of digital authentication on top of them.
Frequently Asked Questions
Can I issue an export invoice in Indian Rupees?
Technically, yes — if your buyer agrees and if RBI has permitted INR settlement for that specific country or transaction type. India has INR trade settlement arrangements with certain countries. However, for most standard international trade, invoicing in freely convertible foreign currency (USD, EUR, GBP) is both standard practice and required for normal FEMA compliance and eBRC generation. Unless you have a specific commercial or regulatory reason to invoice in INR, use foreign currency.
Do I need a new invoice number series for exports, or can I use the same series as domestic invoices?
GST rules allow a single invoice number series for all supplies (domestic and export) or separate series (e.g., "DOM" prefix for domestic and "EXP" prefix for exports). Either approach is acceptable as long as the series is sequential and unique within the financial year. Many exporters find a separate series cleaner for reconciliation and audit purposes.
My buyer wants the invoice in their local language (French, German, Arabic). Is this required?
For Indian customs purposes, the invoice must be in English. For destination country customs purposes, requirements vary. Many countries accept English invoices. Some EU markets may require local language translations. The practical approach: issue your English invoice as the primary document, and provide a translation as a supplementary document if the buyer requests it. Do not replace your English invoice — supplement it.
What is the difference between a "Tax Invoice" and a "Commercial Invoice" for export purposes?
For exports, they are the same document. When you issue the commercial invoice for an export transaction, it must comply with GST tax invoice rules — which means it is simultaneously a "commercial invoice" (the billing document between you and the buyer) and a "tax invoice" (the GST compliance document). In practice, you create one document and call it "Commercial Invoice / Tax Invoice" or simply "Invoice." Issuing two separate documents — one commercial and one tax — for the same export transaction is unnecessary and creates confusion.
The LC requires "Signed Commercial Invoice." What does this mean?
It means the invoice must bear a wet signature (and usually a company stamp) from an authorised representative of your company. An unsigned invoice is a common discrepancy under LC transactions. Always sign and stamp your commercial invoices for LC shipments — and ensure the person signing is identified by name and designation below their signature.
I made an error on an invoice after the shipment was done. How do I correct it?
Under GST, you can issue a Credit Note (to reduce the invoice value) or Debit Note (to increase it) to correct an original invoice. For export invoices, the correction must be carefully considered — if the error is in the invoice value that was declared on the Shipping Bill, the Shipping Bill may need amendment through your CHA before you can correct the invoice. Simple clerical errors that do not affect value (a typo in the buyer's address, a formatting issue) can often be corrected by issuing a corrected invoice with a note referencing the original. For any correction that affects the customs-declared value, consult your CHA before taking action.
Conclusion
The export commercial invoice is not a form you fill in — it is a precisely constructed legal and commercial document that must simultaneously satisfy the requirements of Indian GST law, international commercial practice, your buyer's bank's LC requirements, customs at two ends, and your own refund and incentive claim needs.
Build your invoice template carefully. Include every mandatory field. Get the GST declaration right — LUT route or IGST payment route, consistently applied across invoice and Shipping Bill. Check the Incoterms, the HS code, and the FOB value against the Shipping Bill before every clearance. Sign and stamp every original.
A clean, complete, correctly formatted export invoice is one of the most effective things you can do to ensure your shipments clear smoothly, your payments arrive on time, and your GST refunds and incentive credits process without delay. It takes 10 minutes to get it right on every shipment — and potentially weeks to fix the consequences if you get it wrong.
