Short answer

Export invoicing software should issue foreign currency invoices with every rule 46 export field.¹ Rule 46 requires the client's country of destination and, under an LUT, the export endorsement.¹ Refrens, Vyapar and Zoho Invoice pages mention multi-currency or foreign currency handling.³⁴⁶ None of the four vendor pages checked in October 2026 mentions LUT endorsement text.²³⁴⁵

Applies to	Governed by	Deadline	Penalty	Last verified
GST-registered service exporters issuing invoices	CGST Rules, rules 34 and 46¹	Not applicable	Not applicable	28 October 2026
Registered persons with aggregate turnover above ₹5 crore	Notification No. 10/2023-Central Tax⁷	E-invoicing from 1 August 2023⁷	Not applicable	28 October 2026

Invoicing software saves time once you bill several foreign clients a month, but a tool built for domestic GST invoices does not always handle exports well. An export invoice needs fields a domestic invoice does not, such as the country of destination and the export endorsement, and it is usually in a foreign currency.¹

This page sets out what to check, then summarises what four vendors' own pages say about export-relevant features. Vendors are listed alphabetically. This site does not rank or recommend any tool and has no commercial relationship with any of them.

What does invoicing software for Indian service exporters need to do?

Invoicing software for exporters needs to produce invoices with the rule 46 export particulars of the CGST Rules, in a foreign currency, and handle the practical needs of foreign billing.¹ Use this checklist when you trial a tool:

Feature	Why it matters for exports
Foreign-currency invoices	Clients pay in $, £, € and other currencies
Exchange rate and rupee value	Rule 34(2) values a registered supplier's export at the exchange rate under generally accepted accounting principles
Client country and address of delivery	Required by the export proviso to rule 46
Place of supply outside India	Shown on the invoice under rule 46
Custom endorsement text	For the rule 46 LUT or IGST-paid wording
SAC for each service line	Rule 46 asks for the code for the service
Separate numbering series	Up to 16 characters, unique for the financial year
Recurring invoices	Monthly retainers and subscriptions
Payment reminders	Chasing overdue foreign invoices
Export to accounting or GST tools	Feeding returns and bookkeeping

The rule-based items in the table come from rules 34 and 46 of the CGST Rules.¹ The exact endorsement for an export under a Letter of Undertaking (LUT) is:¹

SUPPLY MEANT FOR EXPORT/SUPPLY TO SEZ UNIT OR SEZ DEVELOPER FOR AUTHORISED OPERATIONS UNDER BOND OR LETTER OF UNDERTAKING WITHOUT PAYMENT OF INTEGRATED TAX

Who needs invoicing software for export invoices?

Invoicing software for exports suits exporters who bill several foreign clients a month; a freelancer with a few invoices may not need it, and larger businesses may need e-invoicing as well.⁷

Entity type	Applicable	Why	Best for
Freelancer with a few invoices a month	Optional	A free generator can produce an invoice with the export fields	The export invoice generator
Freelancer or agency billing several clients a month	Yes	Recurring invoices, reminders and numbering save time	Retainers and subscriptions
Registered person above ₹5 crore aggregate turnover	Yes, with e-invoicing	E-invoicing applies above ₹5 crore from 1 August 2023⁷	Growing agencies and IT firms

How do you test invoicing software for export invoices?

You test invoicing software by building one sample export invoice end to end before you commit:¹

Create a foreign client with a full overseas address and country.
Raise an invoice in the client's currency with your SAC and a specific description.
Add the rule 46 endorsement exactly, and your LUT reference if you include one.¹
Check the place of supply shows "outside India" and that no CGST or SGST is applied.
Check the numbering series stays within 16 characters.¹
Export the invoice as PDF and check every field prints.
Export the data to your accounting or GST workflow and confirm the export is classified correctly.

If any field cannot be added, the tool may still work with a custom template, but test it first.

What rules and thresholds apply to export invoices made with software?

Export invoices made with software follow rules 34 and 46 of the CGST Rules, and registered persons above ₹5 crore aggregate turnover also follow the e-invoicing rule.¹⁷

Item	Requirement	Source
Export particulars	Country of destination, address of delivery, SAC, description and value	Rule 46¹
Endorsement under an LUT	The rule 46 wording in full	Rule 46¹
Invoice number	Up to 16 characters, unique for the financial year	Rule 46¹
Rupee value	Exchange rate under generally accepted accounting principles	Rule 34(2)¹
E-invoicing	Aggregate turnover above ₹5 crore, from 1 August 2023	Notification No. 10/2023-Central Tax⁷

What happens if invoicing software gets an export invoice wrong?

If invoicing software leaves out a rule 46 export particular or applies domestic tax, the invoice does not match what rule 46 requires for an export, and you have to correct it by hand or in a custom template.¹

Domestic tax applied: CGST or SGST on an export invoice under an LUT signals the place of supply was set inside India.
Endorsement missing: an invoice under an LUT needs the rule 46 wording in full.¹
Numbering too long: rule 46 allows up to 16 characters.¹
Wrong classification downstream: exports misclassified in your accounting or GST workflow feed the wrong figures into returns.

See the export invoice format guide for what each field means.

What do invoicing software vendors say about export features?

Of the four vendor pages checked on 28 October 2026, three mention multi-currency or foreign currency handling and none mentions LUT endorsement text.²³⁴⁵⁶ "Not stated" means the page we read did not mention the feature; the product may still offer it. Vendors are listed A to Z.

Vendor	Multi-currency or foreign currency	LUT or export endorsement	Recurring invoices	Pricing on page	Best for
Invoice Ninja	Not stated on the page we read	Not stated	Yes, "Auto-Billing & Recurring Invoices" listed under the free plan	Free plan; paid plans from $14 a month²	Freelancers who want recurring billing on a free plan
Refrens	Yes, says it lets you "create invoices in any currency"	Not stated	Yes, for retainers and subscriptions	Not stated on the page we read³	Freelancers billing clients in several countries and currencies
Vyapar	FAQ says it tracks "multi-currency transactions"	Not stated	Not stated	Not stated on the page we read⁴	Businesses tracking bill payments in several currencies
Zoho Invoice	Yes, help page says you can add currencies and exchange rates, with automatic rate fetching	Not stated	Not stated on the pages we read	Describes itself as free GST invoicing software for small businesses⁵⁶	Small GST-registered businesses that also use Tally

Invoice Ninja: says on its home page that you can "set up recurring invoices and auto-bill clients", and lists a free plan alongside Pro at $14 a month and Enterprise at $18 a month, with Enterprise pricing varying by number of users.² The page links to a self-hosting option without detail.
Refrens: says on its freelancer invoicing page that it "supports invoicing for clients across different countries and currencies", offers recurring invoices "for retainers, subscriptions, monthly services, or ongoing projects", and provides automated payment reminders.³
Vyapar: answers in an FAQ on its home page that it helps you track bill payments, "including multi-currency transactions".⁴ The page we read did not describe export invoices or LUT text.
Zoho Invoice: describes itself as "Free GST invoicing software for small businesses", mentions predefined GST rates and export of GSTR-3B data in JSON, and lets you export invoices in XML for import into Tally.⁵ Its help page on currencies says you can add the currencies and exchange rates you deal with, and that exchange rates can be fetched automatically.⁶

What are the common mistakes when choosing invoicing software for exports?

The common mistakes are choosing a tool built for domestic invoices without testing an export invoice, and assuming a vendor page lists every feature.¹²³⁴⁵

No sample invoice: test with a full export invoice before relying on a tool.
Assuming a dedicated LUT field: none of the vendor pages we read described one, so check for a notes or footer field.³⁴⁵
Ignoring the rupee value: rule 34(2) values the export at the exchange rate under generally accepted accounting principles.¹
Outgrowing the tool: larger exporters also need bookkeeping in multiple currencies, GST return preparation and, above ₹5 crore aggregate turnover, e-invoicing.⁷ See accounting software for multi-currency businesses, export compliance software and e-invoicing for export of services.

Frequently asked questions

Does invoicing software need to be GST-certified for export invoices?+

The CGST Rules set what an export invoice must contain, and they do not name the software that produces it. What matters is that the invoice carries the rule 46 particulars, including the country of destination, and the export endorsement where you supply under a Letter of Undertaking.¹ Check the printed invoice, whichever tool you use.

Can you add the LUT endorsement in any invoicing software?+

You can usually add the LUT endorsement through a notes, terms or footer field, but check each tool. None of the vendor pages we read in October 2026 described a dedicated LUT field.³⁴⁵ The exact wording to use is in rule 46 of the CGST Rules, so copy it in full.¹

Do service exporters need e-invoicing for export invoices?+

E-invoicing applies to registered persons whose aggregate turnover exceeds ₹5 crore, from 1 August 2023 under Notification No. 10/2023-Central Tax.⁷ Most freelancers are below this threshold, but growing agencies and IT firms should check their aggregate turnover each year and choose software that can generate e-invoices.

Is free invoicing software enough for a freelancer who exports services?+

Free invoicing software can be enough for a freelancer who exports services, if it handles foreign currency and lets you add the export fields. Invoice Ninja lists a free plan, and Zoho Invoice describes itself as free GST invoicing software for small businesses.²⁵ Test either with a sample export invoice first.

Which invoicing software is best for Indian exporters?+

This site does not rank invoicing software for Indian exporters. Compare tools on the export features checklist using each vendor's own documentation, then raise a sample export invoice with the rule 46 particulars and endorsement in each.¹ The tool that prints every field correctly for your work is the one to use.

Can invoicing software send export invoice data to Tally?+

Some invoicing software can send export invoice data to Tally. Zoho Invoice says it lets you export invoices in XML for import into Tally, and mentions export of GSTR-3B data in JSON.⁵ For other tools, check the vendor's documentation and test that exports land in the right ledger.
