View as .mdUpdated Oct 30, 2026

This guide shows cashiers and owners how to sell with the SmartPOS Business app: start a sale, add items by tapping or scanning, choose a customer, give discounts, take cash, card or split payments, sell on credit with part payments, print or share the receipt and close the cash register. Everything follows the same rules as the web POS.

Before you start

You are signed in and the right location is selected on Home.
Products are on sale at this location (added on the web or in the app).
Payment methods are turned on for the location on the web (Settings › Business Locations).
If your business uses cash registers, a register is open (the app asks).
Optional: a Bluetooth receipt printer paired in Settings › Printers.

The Sell tab

Sell is the cashier’s start screen. It shows whether the register is open, a big New sale button and shortcuts: Parked & drafts, Recent sales, Return, Cash register, Offline and Scan & Go (when your store uses the Shopper app). Latest sales lists today’s sales.

If the register is closed, tap Open register, count the cash in the drawer, enter it as Starting cash and confirm.

Sell on credit and take part payments

Customers often take goods now and pay over time – for example 20 % today, 50 % next week and the rest at month-end. In the app:

Choose the customer in the cart (credit can’t go on the walk-in customer).
Tap Pay. On Payment, turn on Pay later (credit). The hint says The balance is added to the customer’s account.
Enter what the customer pays today (for example 20 % of the total), or nothing at all. The screen shows … will be due.
Tap Complete sale. The sale is saved as Partial (some paid) or Due (nothing paid).
When the customer pays the next part, open Customers, pick the customer and tap Receive payment – or open the sale in Sales and tap Add payment. Enter the amount and method. Repeat until the balance is zero and the sale shows Paid.

If the customer has a credit limit and this sale goes over it, the app warns Over the credit limit – tap Continue anyway only if you accept the risk (the server may still refuse it).

Sale detail with a Partly paid badge, a progress bar of Paid 329.28 and Due 329.28, and an Add payment button — A partly paid sale. Add payment records the next instalment.

For the full credit workflow, limits and advances, see Credit and partial payments and Customers and ledger.

After Sale complete tap Print (Bluetooth printer) or Receipt to open it. On the receipt screen you can Print, share it with the share button (Share as PDF, Share as image, Share invoice link, Copy invoice link) or tap the WhatsApp button (Send on WhatsApp) to send the customer a thank-you message with the invoice link. Tap Next sale to start again.

Receipts are printed on 58 mm or 80 mm Bluetooth thermal printers; Arabic and Urdu receipts print correctly. A cash drawer plugged into the receipt printer can be opened by the printer.

Park, drafts, quotations and recent sales

Park (in the cart) saves the sale on this phone with an optional name so you can serve the next customer. Recall it from Sell › Parked & drafts › Parked.
Drafts and Quotations saved from the Payment screen are on the server and show in the other two tabs of Parked & drafts for this location.
Recent sales lists sales with Paid, Partial or Due badges. Tap one to reprint, share, add a payment or start a return.

Parked & drafts screen with tabs Parked, Drafts and Quotations and the empty message No parked sales — Parked sales stay on the phone; drafts and quotations live on the server.

Close the cash register

Open Sell › Cash register. It shows Expected cash, Starting cash, Sales, Refunds, Expenses and totals By payment method (if your role may view register totals).
Tap Close register.
Count the drawer with Count by notes or Enter total, and add Card slips, Cheques and a Note (optional).
The app says The drawer is balanced, More cash than expected or Cash is short. Confirm to close.

Tips and mistakes to avoid

Always pick the customer before paying when you give credit.
If the connection drops while saving, the app asks Did the sale go through? Check Recent sales before charging again – the app protects against double sales, but look first.
Your role may have a maximum discount; the app tells you Your maximum discount is …%.
For sales without internet, set up offline selling in advance.

Frequently asked questions

How do I give a customer credit in the app?

Choose the customer first, then on Payment turn on Pay later (credit). Enter what they pay now (or nothing) and tap Complete sale. The rest is added to the customer's account as due.

The customer paid 20 percent now. How do I collect the rest later?

Sell with Pay later (credit) and enter the 20 percent as the payment. Later open the customer and tap Receive payment, or open the sale in Sales and tap Add payment. Repeat for each instalment.

Why can't I complete a sale with less than the amount due?

Without Pay later the full amount must be paid. Turn on Pay later (credit), which needs a real customer, not the walk-in customer.

How do I print a receipt?

After Complete sale tap Print. Pair a 58 mm or 80 mm Bluetooth receipt printer first in Settings › Printers. You can also share the receipt as a PDF, an image or on WhatsApp.

Can I change the price of an item?

Only if your role allows it. Tap the item in the cart to change quantity, price, discount and note. If you see You can't change prices, ask an admin.

What is Park?

Park saves the cart on this phone so you can serve the next customer and recall the sale later from Parked & drafts.

Do I need to open a cash register?

Only if your business uses cash registers. The Sell tab then shows Open register and asks for the starting cash. If no register is needed it says Ready to sell.

Why does the total change after I tap Pay?

The app asks the server to confirm the prices, automatic discounts and customer prices. The Payment screen says Prices confirmed by the server once it has done so.
