GST Billing Software for Retail Shop India — Free, Fast and AI-Powered

Running a retail shop in India is genuinely hard work. Stock, customers, suppliers — and then at the end of the day, you still have to sit down and generate GST bills for every B2B sale.

For most shop owners, this ends up done by hand, in some basic Excel file, or with expensive software carrying way more features than they'll ever use and none of the simplicity they actually need.

GST Maker takes a different approach. It's a free, AI-powered GST billing tool built for Indian retail — kirana stores, wholesalers, garment shops, hardware stores, whatever your trade is. Invoices in under 60 seconds, inventory tracked, expenses recorded, GST compliance handled — all from one free tool.

Why GST billing is genuinely harder for shop owners than it should be

Most shop owners aren't accountants. They know their products, their customers, their margins cold — but GST throws up questions that aren't always obvious.

Which HSN code applies to your product, for one. There are thousands of them, and a garment shop selling cotton shirts, silk sarees, and synthetic fabric needs a different code for each. Get it wrong, and the invoice isn't compliant, which becomes a real problem during an audit.

Then there's CGST+SGST vs IGST. Most kirana and retail shops sell locally, so CGST+SGST is the default — but the moment a B2B buyer from another state places an order, it switches to IGST, and remembering to flip that manually every time is exactly where mistakes creep in.

There's also just the sheer volume — a busy shop might generate 20-30 invoices a day, and tracking invoice numbers, customer GSTINs, and return-ready data by hand at that pace is close to impossible.

And on top of all that, most of the software built for traders is bulky, needs training, and charges a monthly fee that eats straight into already-thin margins.

GST Maker was built to remove all of this — for free.

How it actually works for a shop owner

Set up your shop profile in about 5 minutes. Name, GSTIN, address, logo, once — it auto-fills every invoice from there.

Add your products with HSN codes attached. Name, code, standard price, GST rate — save once, and it's a one-click dropdown on every invoice after. No more hunting down codes mid-sale.

Save your regular customers. Retailers, dealers, distributors — GSTIN and address saved once, selected in a click every time they order again.

Let AI Magic Fill do the rest. It reads whether your customer's in the same state or not and applies CGST+SGST or IGST automatically, calculates the tax instantly, assigns the invoice number in sequence, and has a professional PDF ready in seconds.

Share it or print it. WhatsApp link, PDF download, or print directly — your customer gets a clean GST bill instantly either way.

Common HSN codes shop owners actually need

Finding the right code is one of the bigger headaches here, so this table covers the common ones:

AI Magic Fill suggests the right code as you type the product name, so this table is more of a backup than something you'll need to memorize.

A stationery and gift shop in Lucknow

Deepak runs a stationery and gift shop in Lucknow, selling to schools, offices, and walk-in customers, with a few school buyers in Kanpur and Varanasi too.

He used to run everything through a basic Excel template — manually working out 12% on stationery, 18% on gift items, and remembering different HSN codes across categories. A big school order could take him 20-25 minutes to invoice.

Now, with everything saved in GST Maker, a 15-line-item school order takes him under 3 minutes — CGST+SGST applies automatically since Kanpur and Varanasi are both still UP — and he just sends the link to the school admin over WhatsApp, no PDF attachment needed.

A garment wholesaler in Surat

Rajesh runs garment wholesale out of Surat, supplying retailers across Gujarat, Rajasthan, Maharashtra, and MP, with 60-80 invoices going out a month.

Between multiple states and multiple fabric types at different GST rates, this used to be genuinely stressful — one slip, and a retailer's ITC claim would fail.

Now each fabric type is saved with its correct HSN code and rate, Gujarat orders get CGST+SGST automatically while Rajasthan/Maharashtra/MP get IGST, and his 80 monthly invoices take about 2 hours total instead of eating a full day. His GSTR-1 data is a one-click export at month end, and his retailers haven't had an ITC mismatch since he switched.

A kirana store owner in Chennai

Lakshmi runs a kirana store in Chennai. Most of her sales are B2C and don't need a GST invoice, but her wholesale purchases from distributors do, and she occasionally sells in bulk to nearby canteens and hostels.

For those bulk B2B sales, GST Maker generates proper tax invoices with everything required. And for tracking her own purchases from distributors, she just uses the Expense Tracker to keep records clean — which comes in handy at year-end for ITC claims on anything GST-eligible she bought.

What shop owners actually use daily

Tax invoices with HSN codes, correct tax types, item-wise breakup, and proper sequential numbering — essential for every B2B sale.

Inventory tracking that updates as you invoice, so you notice a product running low before your customer does.

An expense tracker for purchase bills and business expenses — useful both for ITC and for keeping your books clean generally.

Client management that saves every regular buyer's GSTIN and address, selected from a dropdown instead of retyped every time.

GST reporting that hands you a GSTR-1 ready report each month, already organized.

AI Magic Fill handling the CGST/SGST vs IGST decision and suggesting HSN codes as you type.

The public share link for instant WhatsApp sharing, no app needed on the customer's end.

And recurring invoices, if you've got a buyer who orders the same bulk amount every month — set it up once and let it run on its own schedule.

What it actually costs

Nothing, for all the core billing features. No monthly fee, no per-invoice charge, no card required to sign up.

For a shop running on thin margins, that's not a minor detail — you get proper GST billing, inventory tracking, expense management, and reporting without adding a recurring software cost to your overhead.

Questions people usually ask

Is it actually free for a retail shop? Yes — invoicing, inventory tracking, expense tracking, client management, and GST reporting are all in the free plan.

How does it help with HSN codes? AI Magic Fill suggests the right one as you type the product name. You can also search and save codes manually against each product so they auto-fill going forward.

Does it handle both B2B and B2C sales? Yes — proper tax invoices with buyer GSTIN for B2B, and GST-compliant invoices without that requirement for B2C.

Can one invoice have multiple GST rates? Yes — 5%, 12%, 18%, 28%, whatever mix your items need, calculated and shown separately per line, with the correct total.

How does inter-state billing work? Select a customer from a different state, and it switches from CGST+SGST to IGST on its own — nothing to change manually.

Can I actually track my shop's inventory here? Yes, stock levels update as you invoice, so you can see what's moving and what's running low.

How do I use this for GSTR-1 filing? At month-end, GST Maker generates a ready report with all your invoice data organized correctly — you just use it when filing on the GST portal, no manual re-entry.
