Free POS on your phone: how to take payments in your shop without buying anything

The problem with traditional POS systems for small shops

A modern cash register costs between €300 and €1,200. Then come monthly fees, maintenance and tech support. For a small shop, a takeaway pizzeria or an artisan market stall, that's often an investment you can't justify.

The good news: the phone already in your pocket can do everything you need, for nothing.

What does a POS on your phone actually do?

With TIENDAONLINE your smartphone becomes a full point of sale:

• •Touch catalog: your products with photo, price and stock. Tap the product to add it to the cart.
• •Digital receipt: at the end of the sale, the system calculates the total and shows you payment options.
• •Flexible payment methods: cash, card (using your external card reader), bank transfer or WhatsApp.
• •Automatic stock deduction: every sale reduces stock in real time.
• •Receipt sharing: send the order summary to your customer directly on WhatsApp.

How to use it: 3 steps

1. Open the POS

From the dashboard, tap "POS". You'll see all your products as large buttons with images.

2. Add items

Customer asks for a pizza and a drink? Tap 🍕, tap 🥤. The total updates in real time.

Need to apply a discount? There's a direct field to take a flat amount off before charging.

3. Charge and share

Pick the payment method, confirm, and the green success screen appears. From there you can send the summary on WhatsApp with one tap.

What it can't do (important to know)

TIENDAONLINE does not issue tax-compliant electronic receipts linked to your tax authority. If your business requires every transaction to be fiscally registered, you need a certified electronic cash register.

For many small businesses though — over-the-counter sales without a tax-receipt obligation, market stalls, home delivery, online orders coordinated via WhatsApp — this system is enough and much more practical.

Good fit: takeaway pizzerias, cafes, neighborhood shops, greengrocers, craftspeople, street vendors, market stalls.

You'd need more if: your business is required to issue a fiscal receipt for every transaction.

The real benefit: everything in one place

The problem with using WhatsApp just for orders and a spreadsheet for inventory is that everything is separate. You get to end of day and don't know how many sales you made, which product sold the most, or whether the stock is up to date.

With TIENDAONLINE everything is connected:

• •Every POS sale updates stock automatically
• •Your reports show how much you took today, this week and this month
• •You can immediately see your top 5 best-selling products
