How to setup a simple POS system in minutes

There are several reasons to use a cash register to sell goods or services.

Thanks to printing on a small POS printer, we can quickly print a receipt. The customer obtains proof of purchase, and we resolve the legal requirements.

Another important thing is that we get an overview of sales. A sales overview will help our accountant. And if we have more employees selling goods or services, we will get an overview of sales per individual employee. And finally, it’s not just about receiving cash. We want to accept credit cards also. And the sales overview should include all this information. You can check the example of sales overview there.

The question is which cash register to buy.

If we want a cheap solution, the easiest way is to buy an Android phone or tablet and install the cash register there. The advantage is that we can buy an Android phone very cheaply and we are not dependent on one manufacturer. We can also use various accessories such as chargers, power banks.

A small POS Bluetooth printer we recommend for printing. The advantage is portability and cheap printing. For example CASHINO PTP-II is ideal printer. The battery lasts a very long time and the wireless connection is convenient. Another option is to use a POS USB printer. However, this is only suitable for fixed installations.

POS software is the next thing. Elementary POS is lightweight and easy to use. You can install Elementary POS from the Goole Play easily. If Google Play is not available on your device, you can download it from the Elementary POS site for free. After we install the app, we should check the tax settings first. And the second step is to define sale items if we want to use them.

Get it on Google Play

Elementary POS automatically sends all receipts to the cloud, so no backup is necessary. We can export all sales from all cash registers to a single Excel file. Excel is a powerful tool for post-sales processing. It is possible to filter and sort by date of sale, price of goods, taxes, type of payment (cash, card) and other columns. If the cash register is used by more than one employee, the cash register automatically records who registered the revenue and this information is also available in the Excel file.

Finally, if we want to accept credit cards, we can buy a payment card reader. As a card reader, we recommend using SumUp. Elementary POS sends the amount to the card reader and will automatically print the payment confirmation.

We don’t even have to print receipts. Our customer can find his/her receipt as PDF file at We only need to provide unique code to our customers. The code is generated automatically.
