Ahmedabad has businesses at every size, from a freelance designer in a co-working space to an exporter with an ERP and a finance team. Most of the small ones are told they need billing software, and most billing software now comes with a monthly fee. Often that fee is unnecessary.
This guide is for owners, freelancers and office managers who want to know when free invoicing is genuinely enough, which kind of free tool fits, and the point at which you should pay for something more. We make two of the free tools mentioned here, so we have tried to be clear about their limits.
What are the free options?
There are three broad kinds of billing tool, and they solve different problems.
| Kind of tool | Suits | Where data lives | Cost |
|---|---|---|---|
| Browser invoice generator | A few invoices a month, freelancers, one-off sales | In your browser, and in the PDF you save | Free |
| Offline desktop billing app | Daily billing, counters, stock, receipts | On your own computer | Free (CrizaVoise) |
| Accounting or ERP software | Books, returns, several users, e-invoicing | Usually a vendor's server or your office server | Usually paid |
Criza Labs makes the first two: the online GST invoice generator and CrizaVoise, a free and open-source desktop app. The third kind is what your accountant probably uses already, and nothing here replaces it.
For freelancers and consultants: a browser tool
If you are a developer, designer, photographer, tutor or consultant in Ahmedabad, you may send five invoices a month. Installing software for that is overkill.
A browser generator lets you enter your details and the client's, add line items, choose CGST and SGST for a client in Gujarat or IGST for one in another state, and save a PDF. Ours can add a UPI QR code with the amount filled in, has tax invoice, proforma, quotation and bill of supply layouts, and does not send what you type to us.
Two habits make it work well:
- Keep one invoice number series for the financial year, with no gaps or repeats. Rule 46 allows up to 16 characters, and our GST invoice format guide explains the rest.
- Save every PDF in one folder named by financial year, and send the folder to your accountant at the end of each quarter.
For shops and small traders: an offline desktop app
Billing every day changes the picture. You want your customers and products remembered, invoice numbers handled for you, receipts printed, stock reduced as you sell, and a list of who owes you money.
That is what CrizaVoise does. It runs on Windows, Linux and macOS, prints on 58 mm and 80 mm thermal printers, makes GST invoices, quotations, receipts and credit or debit notes, and shares bills on WhatsApp with your UPI ID. Because it works offline, a busy counter in a market such as Relief Road or Ratanpol keeps billing even when the network is slow.
The trade-offs are honest ones. Data lives on one computer, so you take backups. There is no paid support line. And it does not connect to your accountant's software, so at the end of the month someone may still need to enter totals there.
When does e-invoicing apply?
This is the line where free offline tools stop being enough for B2B sales.
Under Notification 10/2023-Central Tax, from 1 August 2023 e-invoicing applies to registered persons whose aggregate turnover in any financial year from 2017-18 onwards exceeded ₹5 crore. For those businesses, a B2B tax invoice needs an Invoice Reference Number (IRN) from the government's Invoice Registration Portal. Some sectors are exempt, and the portal has added rules on how quickly invoices must be reported for larger taxpayers.
Neither our invoice generator nor CrizaVoise connects to that portal. If you are above the limit, you need the portal itself or accounting software that generates the IRN. If you are near the limit, plan the move before you cross it rather than after. Your accountant is the right person to confirm where you stand.
Signs you have outgrown free billing
Free tools are a starting point, not a test of how serious a business is. These are the signs it is time for more:
- Your accountant retypes your bills into the books every month, and mistakes appear in your returns.
- You have two counters or branches that need to share one stock count.
- You must e-invoice, as above.
- Dealers or customers want to order themselves, rather than by phone or WhatsApp.
- You cannot answer a simple question such as last quarter's sales by product without an evening of work.
If only the first applies, the answer may be an export or an integration rather than a new system. We explain the trade-offs in custom software or off-the-shelf?, and what such work tends to cost in what custom software development actually costs.
Where Criza Labs fits for Ahmedabad companies
Many established firms in Ahmedabad already run accounting or ERP software, and the problem is the work around it: orders arriving by email and WhatsApp, invoices made in one place and entered again in another. That is integration work, and it is often cheaper than replacing anything.
We are two founders who build every project ourselves, at a fixed price agreed in writing, and we work with companies in Ahmedabad remotely, in Gujarati, Hindi or English. If you want CrizaVoise extended for your business, billing linked to your books, or a dealer ordering portal, see our custom software development service or tell us what you need.
If you just need to send an invoice today, the free generator is the quickest place to start.

Frequently asked questions
What is the best free billing software for a small business in Ahmedabad?
It depends on how often you bill. For occasional invoices, a browser-based generator such as the free one on criza.dev is simplest. For daily counter billing with stock, receipts and payment tracking, a free desktop app such as CrizaVoise is a better fit. Neither replaces accounting software for your books.
Can a freelancer in Ahmedabad use a free invoice generator?
Yes. A freelancer who sends a few invoices a month can make each one in a browser and save it as a PDF. If you are GST registered, include your GSTIN, the SAC code and the tax, and keep your invoice numbers in one unbroken series for the financial year.
When does e-invoicing become mandatory?
Under Notification 10/2023-Central Tax, from 1 August 2023 e-invoicing applies to registered businesses whose aggregate turnover in any financial year from 2017-18 has exceeded ₹5 crore, for B2B supplies and some others. There are exemptions for certain sectors. Your accountant can confirm whether it applies to you.
Is my data safe in free billing software?
It depends where the data goes. Criza Labs' online invoice generator works in your browser and does not send your invoice to us. CrizaVoise stores everything on your own computer. In both cases you keep your own copies, because we cannot recover them for you.
Can Criza Labs connect billing to our accounting or ERP system?
Yes, that is integration work we do for companies in Ahmedabad. We would look at what your accounting system can import or connect to, and give you a fixed quote before building anything.
