Free vs Paid Billing Software: What You Actually Get

The kinds of "free" billing software

None of these is wrong. The question is whether it fits how many bills you make and how much else you need to track.

What free usually leaves out

• A record of who owes you. A template makes the bill, but the dues still live in your head or a notebook.
• Stock. Free tools rarely reduce stock when you sell or raise it when you buy.
• Automatic numbering that never repeats within the financial year, which GST requires.
• Reports for your CA: sales, purchases and GST totals for the month.
• Quick updates when GST changes. When the rates changed on 22 September 2025, every template with old rates had to be fixed by hand.

What a paid plan should give you

Paying makes sense only if you get more than the free route. At a minimum, a paid billing app should:

• make GST-compliant invoices with HSN codes and the right CGST + SGST or IGST split;
• keep your customers and products, so a bill takes seconds;
• share bills as PDFs, on WhatsApp and email;
• track payments and show what each customer still owes;
• keep your stock in step with sales and purchases;
• give you monthly reports to send your CA;
• show its price openly and let you try it before paying.

Worked example: the cost of "free"

Ramesh runs a hardware shop and makes about 200 bills a month in a spreadsheet. These are his own rough timings, not industry figures, but try the sum with yours.

• Typing a bill, checking the GST and saving it: about 6 minutes. In an app where products and customers are already saved: about 2 minutes. Saving: 4 minutes a bill, or roughly 13 hours a month.
• Working out who owes what at month end: about 3 hours with a notebook, a few minutes in an app.

That is about 16 hours a month. If those hours are worth more to him than a monthly plan, paid software is the cheaper option. If he only made 10 bills a month, the spreadsheet would be fine.

Questions to ask before you pay

• Can I try it with my real bills first, without giving a card?
• Is the price shown up front, and does it go up after the first year?
• Does it work the way I work? On a phone at the counter, on a computer in the office, or both. Online only, or offline too.
• Does it have the current GST rates and the documents I need (invoices, estimates, purchases)?
• What happens to my bills if I stop paying?
• How do I get help when something goes wrong?

How BillBabu's pricing works

We will be straight about it. BillBabu does not have a free-forever plan.

• Every new account gets a 14-day free trial. It starts when you sign up with your mobile number. You do not need a card, and you can make as many invoices and estimates as you like during the trial.
• After the trial, you need a paid plan to make new bills. The bills you already made stay in your account, and you can still open and share them.
• Prices are on our pricing page, and you buy the plan inside the app. The plan covers both the Android app and the web app.

So you know what you would be paying for: BillBabu makes GST invoices and estimates, records purchases that raise your stock, tracks customer payments and dues, and creates sales, purchase and GST summary reports as PDFs in the Android app. It does not work offline, has no iPhone app yet, and does not file GST returns.

And if you need only one invoice today, our free GST invoice generator makes a single invoice in your browser and saves it as a PDF, with no sign-up.

So, free or paid?

Stay free if you make a few bills a month, have no credit customers and no stock to track. Go paid when billing is daily work, when customers buy on credit, or when your CA keeps asking for the same numbers. Either way, use a trial to test the paid option with a week of real bills before you decide. Our guide on choosing the best billing software has a checklist for that week, and ERP vs billing software explains when you need something bigger. To see the sharing side, read how to send a bill on WhatsApp.

Frequently asked questions

Is there a free GST billing app?

Some apps have a free version with limits on bills or features. BillBabu offers a 14-day free trial of the full app instead, with no card needed, and then a paid plan.

Is BillBabu free?

The first 14 days are free, with unlimited invoices and estimates. After that you need a paid plan to make new bills. The prices are on our pricing page.

Can I make GST bills in Excel?

Yes, if the bill has every required GST detail and you number it correctly. It gets harder once you track dues, stock and many products.

Do I need a card to start the BillBabu trial?

No. You sign up with your mobile number and the 14-day trial starts automatically.
