Khata book or billing app? An honest comparison for shops

The red bahi-khata has run Indian shops for generations, and for many it still works. But as customers and items grow, the book starts costing money quietly: an entry missed in a rush, a total that does not match, a customer who “never took that”, a reminder nobody had time to make. This is an honest comparison — including when paper is still the right choice.

What a paper khata does well

• Nothing to learn. Everyone in the family can write in it.
• No phone, no battery, no internet needed.
• Customers trust it. They have seen the same book for years.
• It costs almost nothing.

Where paper starts to hurt

• Totals by hand. One wrong carry-over and every balance after it is wrong.
• No search. Finding what a customer took in March means turning pages.
• No reminders. Collecting depends on you remembering to call.
• One copy. Water, fire, termites or a lost bag — and the record is gone.
• Disputes. A handwritten line is easy to argue about.
• Stock lives somewhere else. The khata knows the money, not what left the shelf.

What the law says about records

If you are registered under GST, you must keep accounts of your sales, purchases, stock and tax at your place of business. GST law allows these accounts in electronic form, with a proper backup and a record of every entry that is changed or deleted, and they must be kept for 72 months (six years) from the due date of the annual return for that year. Paper or app — both are allowed; an app simply makes the backup and the edit record automatic.

When paper is still fine

• A small shop with a handful of credit customers.
• You are not registered under GST and do not need tax records.
• The owner makes every entry personally and checks it daily.

When it is time to switch

A simple test: can you tell, within a minute, how much a customer owes and since when? If not — or if two or more people write in the khata, or credit customers have grown beyond what you can remember — the book is costing you more than an app would.

What to tell your customers

A short message goes a long way when you change how you keep accounts:

Namaste! From 1 November we are keeping our khata on the phone. You will get a WhatsApp message with every entry and can ask for your full statement any time. Your balance today is ₹2,450.

Customers who see every entry as it happens argue less — and they start paying when the message arrives.

How to move your khata to an app without losing anything

1. Pick a cut-off date — the first of a month is easiest.
2. Total every customer’s balance in the book on that date. Do it twice, or with a second person.
3. Enter each customer with an opening balance — “to receive” for those who owe you, “to pay” for suppliers you owe.
4. Send each customer their opening balance on WhatsApp. Differences come up now, while the book is fresh, not months later.
5. Keep the old book safe. It is your record for everything before the cut-off.
6. Run both for a week if it makes you comfortable. After that, the app is your khata.

The Khata in ApnaInventory is built for exactly this: “You gave” and “You got” in two taps, every customer’s balance joined to their bills, a party statement to share or print, a daily cashbook, and a WhatsApp reminder with a UPI pay link. It works with or without GST.

FAQ

Is a digital khata valid in law?

GST law allows accounts to be kept electronically, with a proper backup and a record of changes. If you are not GST registered, a digital record is still useful evidence of what a customer owes — keep it accurate and up to date.

Can my customer see their entries?

You can send them their statement or the entry on WhatsApp whenever you like. Sending each entry as it happens prevents most disputes.

What happens if my phone is lost?

With an app that stores data online, you sign in on another phone and everything is there. Protect the account with a strong password and two-step login.

Do I need GST registration to use a billing app?

No. Shops that are not registered make simple bills and keep their khata in the same app.
