If you sell on Amazon, Flipkart, Meesho or any other online marketplace, you already know that GST filing is very different from a normal shop. Every month you have to pull sales reports from each portal, separate B2B, B2C and credit notes, match the TCS that marketplaces deduct under Section 52, and finally prepare your GSTR-1. Doing this by hand in Excel is slow and error-prone — and the right GST software can turn hours of work into a few clicks.

But not every “GST software” is built for online sellers. Most are made for normal businesses and accountants, and they cannot read marketplace reports. In this guide we compare the 8 best GST software for online sellers in India in 2026, what each is best for, and how to pick the right one for your business.

What to look for in GST software for online sellers

Before you choose, check whether the software can actually handle e-commerce data:

• Marketplace report support – can it read Amazon, Flipkart, Meesho and other portal files directly?
• GSTR-1 JSON & Excel output – does it create a government-format file you can upload to the GST portal?
• TCS reconciliation – can it match the TCS deducted by marketplaces (GSTR-8) with your sales?
• Error checking – does it catch HSN, B2B and Table 12 errors before you file?
• Price and ease of use – is it affordable and simple enough to use every month?

Best GST software for online sellers in 2026

1. GST Tool — Best for online marketplace sellers

GST Tool is built specifically for e-commerce sellers. You simply upload your sales report from Amazon, Flipkart, Meesho, Myntra, Nykaa, JioMart or any of 25+ supported portals, and it instantly converts the data into a ready GSTR-1 JSON and Excel file in the exact government format. It automatically prepares B2B, B2C Small, Credit/Debit Notes, Nil/Exempt, HSN summary and Table 14 (supplies through e-commerce operators), and it also reconciles your TCS data so your return matches what the marketplaces reported.

• Best for: Amazon, Flipkart and Meesho sellers and the CAs who file for them
• Key features: 25+ marketplace support, 1-click GSTR-1 JSON & Excel, automatic TCS reconciliation, built-in error checks
• Pricing: 30-day free trial, then around ₹149/month
• Pros: No manual data entry, made only for online sellers, very fast monthly filing
• Cons: Focused on GST return preparation, not full accounting

2. ClearTax (Clear) — Best all-round cloud GST suite

ClearTax is one of India’s most popular cloud platforms for GST filing, e-invoicing and reconciliation. It is powerful and trusted by many businesses and tax professionals, with strong GSTR-2A/2B matching. It is more of a general GST and compliance suite than a marketplace-specific tool, and it sits at the premium end on price.

• Best for: Mid-to-large businesses and CA firms
• Pros: Complete GST, e-invoice and reconciliation features
• Cons: Premium pricing, not built around marketplace reports

3. Zoho Books — Best for sellers who want full accounting + GST

Zoho Books is a complete accounting solution with GST return filing built in. If you want to manage invoices, expenses, banking and GST in one place, it is an excellent choice, and it offers a free tier for businesses below a certain turnover. Marketplace data usually needs to come in through integrations rather than direct portal files.

• Best for: Sellers who want accounting and GST together
• Pros: Full accounting, clean interface, free plan for small businesses
• Cons: Not a one-click marketplace-to-GSTR-1 tool

4. TallyPrime — Best for established businesses and accountants

TallyPrime is the accounting standard for lakhs of Indian businesses and supports GST returns. Most online sellers, however, first need to import their marketplace sales into Tally, which is an extra step. It works best when you already run your books in Tally and have a way to bring e-commerce data in.

• Best for: Businesses and accountants already using Tally
• Pros: Trusted accounting, widely used, works offline
• Cons: Cannot read marketplace reports on its own

5. Vyapar — Best for small sellers on a budget

Vyapar is a simple billing and GST app popular with small retailers and D2C sellers. It is affordable and easy to use on mobile or desktop, making it good for basic invoicing and GST. It is not designed to convert large marketplace reports into GSTR-1.

• Best for: Small sellers and shops
• Pros: Low cost, simple, mobile-friendly
• Cons: Limited for high-volume e-commerce filing

6. GSTHero — Best for reconciliation and e-invoicing

GSTHero focuses on GST reconciliation, e-invoicing and e-way bills, and offers a Tally connector. It is a solid choice if input tax credit matching and compliance are your main concern, though it is not specialised in marketplace GSTR-1 preparation.

• Best for: Compliance-heavy businesses
• Pros: Strong 2A/2B reconciliation and e-invoice tools
• Cons: Not marketplace-report focused

7. Gen GST (SAG Infotech) — Best value for tax professionals

Gen GST is a desktop and cloud GST return software popular with CAs and tax practitioners who file for many clients. It is budget-friendly and covers all GST returns, making it a good back-office tool, though sellers still need to prepare marketplace data separately.

• Best for: Tax professionals filing for multiple clients
• Pros: Affordable, covers all returns, multi-client friendly
• Cons: No direct marketplace report import

8. myBillBook / Refrens — Best for invoicing-first small businesses

myBillBook and Refrens are easy invoicing tools with basic GST support, suited to freelancers and very small sellers who mainly need GST invoices and simple reports rather than full marketplace return preparation.

• Best for: Freelancers and micro businesses
• Pros: Simple, quick invoicing, low cost
• Cons: Not built for e-commerce GSTR-1

How to choose the right GST software

The best choice depends on the type of seller you are:

• Single-marketplace seller (only Amazon or only Meesho): a specialised tool like GST Tool lets you file in minutes without manual work.
• Multi-marketplace seller (selling on several portals): you need software that supports many portals and merges them into one GSTR-1 — again, a marketplace-focused tool saves the most time.
• CA or tax professional filing for many clients: combine a return-prep tool such as GST Tool with general software like Gen GST or ClearTax for the back office.
• Seller who also wants full accounting: Zoho Books or TallyPrime, paired with a marketplace converter for the GSTR-1 part.

Conclusion

For most online sellers, the fastest and easiest way to file GST is a tool built for marketplaces. While general software like ClearTax, Zoho Books and TallyPrime are excellent for accounting and overall compliance, they were not designed to read Amazon, Flipkart or Meesho reports. GST Tool fills that gap — upload your portal report and get a ready GSTR-1 JSON and Excel in one click, with TCS reconciliation and error checks included.

You can try GST Tool free for 30 days and file your next GSTR-1 in minutes instead of hours. If you sell on a specific marketplace, see our step-by-step guides for Amazon sellers and Meesho sellers.

Frequently asked questions

Which GST software is best for Amazon and Meesho sellers?

For sellers who file from marketplace reports, GST Tool is the most convenient because it converts Amazon, Flipkart, Meesho and 25+ other portal files into a ready GSTR-1 JSON and Excel automatically, with TCS reconciliation.

Is there any free GST software for online sellers?

Some tools offer free tiers or trials. Zoho Books has a free plan for small turnover, and GST Tool gives a 30-day free trial so you can prepare a full GSTR-1 before paying.

Do I need accounting software as well as GST software?

Not always. If you only need to file GST returns from marketplace data, a return-prep tool is enough. If you also want to manage books, invoices and expenses, add accounting software like Zoho Books or TallyPrime.

Can GST software handle TCS deducted by marketplaces?

Good e-commerce GST software can. GST Tool reconciles the TCS that marketplaces deduct under Section 52 (reported in GSTR-8) against your sales, so your GSTR-1 matches the marketplace data.
