A Simple Mobile POS for Market Stalls

A traditional till costs money, takes space and does more than a market stall needs. For many small sellers, a phone is enough to ring up a sale, take payment and keep a record. Here is what that takes, and where it falls short.

What a small seller needs from a POS

• Speed. A queue should not wait while you type. Selling should take a few taps.
• Your usual items one tap away, not buried in a menu.
• Every payment method you accept: cash, card, bank transfer and QR payment.
• A record of the sale, so you know your takings at the end of the day.
• Stock that updates itself, so you do not sell what you no longer have.
• A low price, ideally free to start.

How tap-to-add selling works

Instead of searching for a product each time, your best sellers sit on large buttons. One tap adds one item, another tap adds another. You check the total, tap how the customer is paying, and the sale is done. EzInvoice's Quick Sale works this way: you choose four products for your tiles, and the rest are a search away.

Taking payment

For cash, tap Cash and the sale is recorded as paid. For card or bank transfer, tap the method once the customer has paid. For QR, the app shows the payment QR code you uploaded in Settings, and you confirm once the money has arrived.

Know the limit: EzInvoice records how a customer paid, but it does not process card or QR payments itself. You still confirm that the money arrived in your account, the same as you would with a handwritten receipt.

Keep your stock honest

If you track stock on a product, each sale reduces it. That tells you what to reorder, and it stops you from promising something that has run out. For a stall, do a quick count at close and compare it to the app. A difference tells you about theft, waste or a missed sale.

What a phone POS does not do (yet)

Be honest about the limits before you choose any tool:

• There is no barcode scanning or receipt-printer support.
• You need an internet connection to record a sale.
• It is not a full retail system with supplier orders and multi-store reporting.

For a stall, kiosk or small shop that sells a few dozen items, these limits rarely matter. If you need barcode scanning or printed receipts at volume, you need a different kind of system.

Getting started in an afternoon

1. Create a free workspace and add your products, each with a name and a price.
2. Add a stock count for the items you want tracked.
3. Upload your payment QR code if you take QR payments.
4. Pick your four best sellers for the tiles, and ring up the first sale.

Everything you sell is saved as a record, so at the end of the day you can see what sold and what you took. The Free plan includes a monthly allowance of documents, and each sale counts as one, so check the pricing against how many sales you make.
