Everything the shop needs, writing to one set of numbers.
A sale on credit updates the customer's khata and drops the stock, in one action. That is the whole idea — record it once, and every screen agrees.
SmartKhata covers the credit book, cash book, POS billing, stock, payment reminders and analytics. The credit book and cash book are free forever; the rest is included in the 30-day trial and in any paid plan.


Credit khata
A running ledger per customer and per supplier. Record what you gave on credit and what came back, and the balance updates itself. Open any name to see the full history with dates — so a disputed amount is settled by scrolling, not arguing.
- Separate customer and supplier ledgers
- To-receive and to-pay totals on the dashboard
- Full dated entry history per contact
- Share a statement link the customer can open — no app needed


Cash book
Log money in and money out with a category and a note. Cash and bank are tracked separately, so the closing balance you see is the balance you should be able to count.
- Cash in / cash out with categories
- Cash and bank tracked apart
- Running balance and daily totals
- Attach a photo of the bill to an entry


POS billing
Tap items into a cart, take cash, card or credit, and the invoice is issued with a running number. A credit sale posts straight to that customer’s khata, and stock comes down automatically — no second entry anywhere.
- Product grid built for fast tapping
- Cash, bank or credit payment on the same bill
- Credit sales post to the customer ledger automatically
- Sequential invoice numbers per business
- Share or export the invoice as a PDF


Stock & inventory
Items with cost price, selling price and quantity on hand. Every sale, purchase and adjustment is a stock movement you can trace back. Bring an existing item list in from a spreadsheet instead of typing it twice.
- Cost and selling price per item, with categories
- Stock movements for every sale, purchase and adjustment
- Bulk import from CSV or Excel
- Manual adjustments with a reason


Payment reminders
Send a customer their balance over WhatsApp or SMS, in their language, with a link to a statement page showing exactly how the number was reached. Schedule it and stop deciding every week whether today is the day to call.
- WhatsApp and SMS reminders
- Message in English, Sinhala or Tamil
- Shareable statement link — the customer needs no app
- Schedule reminders instead of sending them by hand


Analytics
Sales and collection trends, cash versus bank, top items, and a receivables aging breakdown that tells you which debts are about to go bad rather than just how much is outstanding.
- Sales and collections over any period
- Receivables aging — current, watch, overdue
- Cash vs bank split
- Top customers and top items


Multiple shops, one login
Run a second shop from the same login and switch between them without signing out — each keeps its own customers, stock, invoices and numbering. Adding businesses beyond your first needs one of them on a paid plan. The same login works on the phone and on the web, and the mobile app records offline and syncs when signal comes back.
- Switch business without signing out
- Separate books, stock and invoice numbers per business
- A second business needs one on an active paid plan
- Works offline on mobile and syncs when you get signal
- Same data on mobile and on the web
And all of it on your phone.
The whole khata in your pocket — for iPhone and Android. Record a credit sale while the customer is still standing there, and it is on your desktop by the time you sit down.
Works without signal
Record sales, credit and payments offline. Everything syncs the moment you are back on data — a dead zone at the counter never stops you serving a customer.
English, සිංහල, தமிழ்
The whole app switches language, including the reminder messages your customers receive. Whoever is at the counter reads it in the language they think in.
The apps are in review. Until they land, the web app runs in any phone browser — sign in and add it to your home screen.

Add your business, record a few customers, and judge it on your books rather than ours. 30 days, no card.
