How to Choose the Right Billing Software for a Small Shop in Tamil Nadu (GST Features Checklist)
Published by Arudra Commercial Services
What to check before you buy billing software for a grocery, textile, medical or hardware shop — with a GST features checklist you can take to any demo.
If you still write bills by hand, moving to billing software is one of the cheapest upgrades a small shop can make. It cuts billing time, stops wrong totals, shows you what is selling, and turns month-end GST work from a weekend job into a report you print.
But there are dozens of options, and most demos look alike. This guide gives you a checklist to judge any billing software — ours included — before you pay. It is written for shop owners in Tamil Nadu. It is general guidance, not tax advice: confirm GST details with your auditor.
Step 1: Write down what your shop actually needs
Before any demo, answer five questions: How many billing counters do you run, or will run in a year? Roughly how many different items do you sell? Do regular customers buy on credit? Do you sell to other businesses who need a GST invoice with their GSTIN? And do you need to track stock, or only bill?
A single-counter provision store, a medical shop and a wholesaler selling to other shops need very different things. Your answers decide which features on the checklist below are essential for you and which are nice to have.
The GST features checklist
If you are GST-registered, the software should do all of this without manual calculation. TODO: have your auditor verify this list against current GST rules before publishing
- Prints a proper tax invoice: your name, address and GSTIN, a consecutive invoice number, date, item description, HSN code, quantity, taxable value, GST rate and tax amount
- Adds the buyer's name, address and GSTIN on B2B invoices
- Charges CGST + SGST on sales within Tamil Nadu and IGST on sales to other states — automatically
- Stores the HSN code and GST rate for each item, and lets you update rates when the government revises them
- Produces GST reports your auditor can use for GSTR-1 and GSTR-3B
- Handles sales returns properly, with credit notes where required
- Separates B2B and B2C sales in reports
- Prints a bill of supply instead of a tax invoice if you are under the composition scheme
- E-invoicing (IRN and QR code) — only needed once your turnover crosses the government limit
Beyond GST: the everyday features that matter
| Feature | Why it matters in a small shop |
|---|---|
| Works without internet | Billing continues through network outages — common in many towns |
| Barcode scanning | Faster billing and no wrong prices on packaged goods |
| Thermal printer support (58mm / 80mm) | Bills print in seconds on cheap paper rolls |
| Stock tracking and low-stock alerts | You reorder before you run out, and see slow-moving stock |
| Credit customer ledger | No more notebook of who owes what |
| Staff logins with permissions | Only you can give discounts, edit prices or delete bills |
| Backup and restore | A dead hard disk does not wipe out your accounts |
| Daily and monthly reports | Sales, profit and best-sellers at a glance |
| Tamil-language support | Staff learn faster; some customers prefer Tamil bills |
Desktop, online or mobile app?
Desktop software runs on the shop computer. It is fast and keeps working without internet; your data stays on your machine, so backups matter. Online (cloud) software runs in a browser and lets you check sales from anywhere, but most need a steady connection to bill. Mobile billing apps are cheap and handy for very small sellers, but slow down once you have many items, a barcode scanner or more than one counter.
For most shops with a fixed counter, desktop software with a reliable backup is the practical choice. If you need to watch several branches from home, ask how the software handles remote access or cloud backup.
Questions to ask at every demo
- Who installs it, and will someone come to my shop if it stops working?
- Is the price one-time or yearly? What does renewal or support cost?
- Is training for my staff included?
- How are backups taken, and how would I restore after a computer failure?
- Can I export my data if I change software later?
- Can you show it working with items like mine, with my printer and scanner?
- Does it print bills in Tamil, and is support available in Tamil?
- What happens when GST rates change — who updates them?
Costs to budget for
The software licence is only part of the cost. Budget for a computer (or check your existing one is fast enough), a thermal printer, a barcode scanner, installation and training, and yearly support if the vendor charges for it. A small UPS is worth adding so a power cut does not interrupt a bill.
Where Arudra Books fits
We built Arudra Books for exactly this kind of shop: desktop billing that works offline, GST invoices with HSN codes, the GSTR-1 Excel workbook and GSTR-3B summary (Premium plan), barcode and thermal-printer support, stock alerts, credit ledgers, staff permissions and backups. We install it at your counter and train your staff in Neyveli, Cuddalore, Chidambaram and nearby towns.
Use the checklist above at our demo too — and ask us anything on it.
Quick answers
Is billing software compulsory under GST?
No. GST rules require correct invoices and records, not a particular software. Billing software simply makes it much easier to get invoices and returns right.
Can I use billing software if my shop is not GST-registered?
Yes. You can still use it for bills, stock and credit tracking; the bills just should not show GST.
How long does it take to switch from manual billing?
Most of the work is entering your items and prices. Arudra Books imports your product list in bulk from Excel, and scanning a new barcode fills in the product details from online catalogues.
