Zoho Books for Indian Exporters: LUT, Foreign Currency Invoicing, and FIRC Compliance

For Indian exporters, the GST framework creates a specific set of bookkeeping requirements that most general-purpose accounting guides do not cover in detail. Getting the zoho books export invoice gst zero rated workflow right means understanding which export type to select, when a Letter of Undertaking applies, how to record foreign currency receipts, and how your invoice data flows into GSTR-1 Table 6A. Miss any one of these steps and you face either a working capital blockage from unnecessary IGST payments or a compliance gap that surfaces during a GST audit. This guide walks through each part of that workflow using the Zoho Books accounting platform, with exact settings, field names, and report paths so your finance team can set this up correctly the first time.

What Zero-Rated GST Means for Indian Exporters

Under the GST Act, exports of goods and services are classified as zero-rated supplies under Section 16 of the IGST Act. Zero-rated does not mean exempt. The distinction matters because an exempt supplier cannot claim input tax credit, whereas a zero-rated exporter can claim a refund of the ITC accumulated on inputs used for export production.

When you create an export invoice in Zoho Books, you must choose one of two supply types:

LUT eligibility is broad. Any GST-registered exporter who has not been prosecuted for tax evasion exceeding Rs. 2.5 crore can apply. The application is filed online through the GST portal (Form RFD-11) and the approval is instant in most cases. The LUT is valid for one financial year and must be renewed each April. For context on how this interacts with e-invoicing thresholds, see the guide on GST e-invoicing in Zoho Books.

Setting Up Your LUT in Zoho Books

Before you can raise a zero-rated export invoice in Zoho Books, you need to enter your LUT details in the application. Zoho Books stores the LUT number and prints it on export invoices automatically once configured.

Step-by-step configuration

1. Go to Settings, then Taxes, then GST Settings.
2. Scroll to the LUT/Bond Details section.
3. Click Add LUT/Bond.
4. Enter the LUT number exactly as it appears on your GST portal acknowledgement. This is typically formatted as ARN followed by a 15-digit alphanumeric string.
5. Set the Valid From date to 1 April of the current financial year and Valid To to 31 March of the next financial year.
6. Save the entry.

Zoho Books will now print the LUT number in the GST details block of every export invoice where you select Export without Payment of IGST. If you export to both SEZ units and overseas buyers, the same LUT covers SEZ supplies under the same zero-rated treatment.

One common configuration gap: if your company has multiple GSTINs registered in Zoho Books (for instance, separate registrations for Maharashtra and Karnataka), you need to add the LUT under each GSTIN separately. The LUT you receive from the GST portal is tied to the specific GSTIN that applied, so a Maharashtra GSTIN LUT cannot be used when raising invoices from the Karnataka branch.

For a full walkthrough of your initial GST configuration, the complete Zoho Books setup guide covers all the foundational settings before you get into export-specific configuration.

Creating Foreign Currency Export Invoices in Zoho Books

Most Indian exporters invoice in USD, EUR, GBP, or AED depending on their buyer’s country. Zoho Books handles multi-currency invoicing natively, but there are specific fields required by customs and GST regulations that you need to populate correctly.

Multi-currency setup

Before creating your first foreign currency invoice, enable the currency in Settings, then Currencies. Set the exchange rate to the RBI reference rate for the invoice date. Zoho Books supports both a fixed rate per invoice and an auto-fetched rate, but the GST portal expects the RBI rate, so avoid using a bank-quoted rate unless it matches the RBI published figure for that date.

Required invoice fields for export compliance

Service exporters do not need port codes or shipping bill numbers. However, they do need to ensure the customer’s country is set correctly in the customer master and that Place of Supply reflects the export destination rather than a domestic state. Zoho Books uses this to determine whether the transaction qualifies as an export of services under the IGST Act conditions, which include that the supplier and recipient are not in the same establishment.

Recording Payments and FIRC Documents in Zoho Books

When a foreign buyer pays your invoice, their bank sends the money through SWIFT to your Indian bank. Your bank then credits the equivalent INR amount to your account after converting at the prevailing rate. The documentary proof of this inward remittance is what the GST department and DGFT require for export benefit claims.

What is an FIRC and eBRC?

A Foreign Inward Remittance Certificate was the physical document banks issued to confirm receipt of foreign currency. Since 2016, the Reserve Bank of India replaced this with the electronic Bank Realisation Certificate, issued through the DGFT eBRC portal. Your bank uploads the remittance data to DGFT, and you download the eBRC from the portal. The eBRC is the accepted document for GST export refund claims, SEIS benefit applications under the Foreign Trade Policy, and audits. Some private banks still issue a physical FIRC on request alongside the eBRC.

Recording the payment in Zoho Books

1. Open the export invoice and click Record Payment.
2. Enter the amount received in the foreign currency (for example, USD 5,000). Do not convert to INR manually.
3. Set the exchange rate to the rate at which your bank credited the INR amount. This may differ from the invoice date rate, and the difference will be posted as a foreign currency gain or loss automatically.
4. In the Reference field, enter the eBRC number or FIRC number from your bank document. This makes reconciliation and audit response faster.
5. Attach the eBRC PDF to the transaction using the attachment icon.

Zoho Books marks the invoice as paid and posts the INR equivalent to your bank account ledger. For thorough month-end close, the guide on bank reconciliation for export receipts covers how to match these entries against your bank statement systematically, including handling advance payments and partial receipts.

Advance receipts against export orders

If a buyer sends an advance before you raise the invoice, record it as a Retainer Invoice in Zoho Books against the customer. When the final invoice is raised, apply the retainer. Zoho Books handles the exchange rate differential between the advance receipt date and the invoice date and posts it correctly. For GST purposes, advance receipts for export of goods are not liable to tax at the time of receipt, but advance receipts for export of services require careful handling depending on whether the services qualify as export of services or are treated as domestic supply.

Reconciling Export Sales with GSTR-1

Table 6A of GSTR-1 is the dedicated section for export invoices. It requires invoice number, invoice date, taxable value in INR, the integrated tax amount (zero for LUT invoices), and for goods exports, the shipping bill number and port code. Errors in this table can delay GST refund processing and create mismatches with ICEGATE customs data.

How Zoho Books populates GSTR-1

Zoho Books generates a GSTR-1 report that pre-fills Table 6A from your export invoices. To view it, go to Reports, then GST Reports, then GSTR-1, and select the filing period. The system pulls invoice number, date, customer country, taxable value (in INR at the invoice exchange rate), and shipping bill details from the fields you entered during invoice creation.

For a complete walkthrough of the monthly filing process, the guide on filing GST returns in Zoho Books covers Table 6A alongside B2B and B2C tables so you can handle the full return without switching between systems.

Cross-checking before filing

1. Run Reports, then Business Overview, then Sales by Customer, filtered to the filing month with customer type Export.
2. Sum the INR taxable value column.
3. Compare this total with the Table 6A aggregate in the GSTR-1 report.
4. If there is a gap, look for invoices where the customer’s GST treatment was set to Registered or Unregistered instead of Overseas. These invoices will appear in B2B or B2CS tables instead of Table 6A.
5. For goods exports, verify that every invoice in Table 6A has a shipping bill number. Invoices without shipping bill details are incomplete for customs reconciliation.

Common Mistakes in Export Invoice Compliance

These are the errors that appear most often in GST audits and GSTR-1 mismatches for Indian exporters using Zoho Books:

Charging IGST when a valid LUT is active

If your LUT is configured in Zoho Books but the invoice export type is still set to With Payment of IGST, you will charge your overseas buyer tax they did not expect to pay, and you will create an unnecessary refund claim. Double-check the export type field every time you raise a new series of invoices, especially at the start of each financial year after renewing the LUT.

Wrong Place of Supply for service exports

For software, consulting, or design services exported to overseas clients, the Place of Supply should not be automatically set to the buyer’s country. Under GST rules, the Place of Supply for services to overseas recipients who are not registered in India is the location of the supplier (your state). Setting it incorrectly to a different Indian state will create an intra-state transaction treated as a domestic supply, pulling the invoice out of Table 6A entirely.

Missing port code on goods export invoices

Port codes are six-digit numbers identifying the customs port through which your goods exit India. Common examples: INMAA1 for Chennai Sea, INDEL4 for Delhi Air, INNSA1 for Nhava Sheva. Zoho Books has a port code field in the shipping details section of the invoice. Leaving it blank means ICEGATE cannot match your invoice to the shipping bill, which holds up the GSTR-1 auto-population from customs data and delays refund processing.

Recording payment at the wrong exchange rate

Using the invoice exchange rate instead of the actual bank credit rate when recording payment creates an incorrect foreign currency gain or loss and misrepresents your actual INR receipts in the P&L. Always enter the rate your bank used when crediting your account, which you can find on the bank statement credit entry or the SWIFT credit advice.

Not attaching eBRC to payment records

The eBRC is your primary document for proving that export proceeds were realised within the required timeframe (currently 9 months for goods, 12 months for services under FEMA guidelines). Attaching it to the payment record in Zoho Books at the time of recording means you have an audit trail tied directly to the invoice and payment, rather than having to search through a separate folder of bank documents months later.

Getting the zoho books export invoice gst zero rated workflow right comes down to configuring each layer correctly before the first invoice goes out: LUT details in GST settings, customer type set to Overseas, exchange rates from the RBI, and shipping bill data entered at dispatch. Once those inputs are in place, Zoho Books handles the GSTR-1 Table 6A population automatically and gives your finance team a single report path from invoice to return filing without manual reconciliation.
