Compare the best POS systems for retail: Tillhub by Unzer, ready2order, Lightspeed Retail, SumUp and ETRON. Find the right system for your business.
Whether you run a fashion boutique, kiosk or grocery shop, a POS system is a central part of day-to-day retail operations. In addition to taking payments, it helps you keep track of stock, analyse revenue, connect different sales channels and comply with legal requirements. Which functions matter most depends on the type and size of your business. The good news: almost all modern POS systems are now cloud-based, meaning you can access important data such as revenue, stock levels and statistics from anywhere, without having to maintain your own servers.
This comparison introduces five established, cloud-based POS solutions for retail and helps you find the right solution for your business requirements:

The technical security device (TSE) for electronic POS systems has already been mandatory since 2020: under the German Cash Register Security Ordinance (KassenSichV), all checkout transactions must be recorded completely and in a tamper-proof manner. In addition, the standardised DSFinV-K interface requires complete POS data to be available in a format that tax authorities can check directly by machine.
New since 1 January 2025: reporting obligation to the tax authorities. Electronic POS systems with TSE must be reported digitally via the ELSTER portal – within one month for new purchases, and likewise when systems are taken out of service. Anyone who fails to comply with this reporting obligation risks a fine of up to EUR 25,000.
Two further changes are emerging, but have not yet been finally adopted: according to the coalition agreement, a mandatory cash register requirement is to be introduced from 2027 for businesses with annual revenue of EUR 100,000 or more, meaning open cash registers would no longer be permitted for this group. It remains unclear whether the threshold will be based on cash revenue or total revenue. At the same time, the Tax Development Act could abolish the receipt issuance obligation for small amounts under EUR 30, while in return increasing penalties for cash register manipulation to up to five years’ imprisonment (as at June 2026).
All six providers presented in this article generally meet the requirements of the KassenSichV and the GoBD – although for SumUp this only applies to the Pro plan, not to the free basic version. A paper-based cash book is therefore no longer sufficient for electronic POS systems, regardless of whether it is a stationary touchscreen till or a mobile tablet solution.
Not every system is equally suitable for every use case or retail segment. Three examples show what matters:
In specialist shops with a large product range or higher-value products – such as fashion boutiques, opticians or jewellery shops – clear management of product variants and flexible payment options are particularly important. Tillhub by Unzer supports item variants and split payments, and offers individual customer profiles where, for example, purchase history, customer preferences or notes can be stored. Stock balancing across branches is also possible. ready2order also supports item variants for size and colour, as well as split payments. SumUp and ETRON each offer a variant function. Lightspeed Retail works with custom tags and categories for brand, colour and size to make even large product ranges searchable.
Perishable goods with a tight time window and changing prices depending on season, variety or quality shape this segment. Tillhub by Unzer offers splash-proof hardware and price books, which can be used to define discounts as well as different prices for specific branches or periods. Fleurop is also one of its major customers. ready2order also supports variable prices and sales by item or by bunch.
For use away from a fixed checkout point – for example at a market stall, at events or as an additional till during peak times – compact, battery-powered hardware is particularly important. Tillhub by Unzer (POS Go) and ready2order (readyGo 2) each offer their own mobile all-in-one device combining till, scanner, printer and card terminal. SumUp can also be used on the move through iPad-based hardware and Tap to Pay, although it does not offer its own compact device. ETRON and Lightspeed Retail enable mobile use via tablet, but do not offer their own compact device.
Provider | Specialist shops, e.g. fashion, optics, jewellery | Floristry | Mobile sales |
|---|---|---|---|
Tillhub by Unzer | Split payments, item variants, individual customer profiles, stock balancing between branches | Splash-proof hardware, price books for flexible pricing, Fleurop as a major customer | POS Go as a mobile device |
ready2order | Split payments, own variant function for size/colour | Sales by item/bunch, flexible daily prices | readyGo 2 as a mobile device |
Lightspeed Retail | Tags/categories for brand, colour, size | No floristry-specific functions | Mobile via tablet, no dedicated device |
SumUp | Own variant function for size/colour | No floristry-specific functions | Tap to Pay, no dedicated device |
ETRON | Own variant function for size/colour | No floristry-specific functions | Mobile via tablet, no dedicated device |
Choosing the right POS system depends heavily on how your business is currently set up – and how you want to grow in future. A fashion boutique has different requirements from a florist or a multi-branch business with several locations.
Systems that combine inventory management, payment processing and branch management in one platform – such as Tillhub by Unzer – reduce complexity and lower the effort required for additional interfaces with external providers. For highly specific requirements, however, a more specialised provider may be the better choice. In addition to the range of functions, you should also consider transparent pricing, good scalability for a growing product range and the quality of support. Especially in the stressful day-to-day running of a shop, a reliable point of contact can make all the difference.
How much does a POS system cost in retail?
Depending on the provider and range of functions, monthly costs are usually between around EUR 20 and EUR 170, plus a TSE fee if this is not already included. Some providers also charge transaction fees per card payment as well as one-off setup or hardware costs, which should be included in the overall calculation.
Which retail POS system with inventory management is recommended?
Tillhub by Unzer, ready2order, Lightspeed Retail and ETRON all offer integrated inventory management with automatic stock updates after every sale. In the free basic version, SumUp only covers basic stock functions; more comprehensive inventory management is only available in the Pro plan. For multi-branch businesses, it is also worth looking at the cross-branch stock overview.
Are iPad/tablet POS systems suitable for retail?
Yes, tablet POS systems or iPad POS systems are suitable for retail wherever complex hardware installation is to be avoided – from small boutiques to market stalls. Tillhub by Unzer and SumUp both run on iPad, while ready2order offers readyTab, its own tablet till with integrated printer and scanner. All three systems can be expanded with receipt printers, cash drawers or barcode scanners if required, without the need for a fixed checkout point.
Which mobile POS system is suitable for retail?
For mobile checkout, for example on the sales floor, at a market stall or at events, Tillhub by Unzer (POS Go) and ready2order (readyGo 2) each offer their own mobile all-in-one device combining till, scanner, printer and card terminal. SumUp can also be used on the move via iPad hardware and Tap to Pay. All synchronise sales automatically with inventory management as soon as an internet connection is available again.
What legal requirements must a retail POS system meet?
Since 2020, electronic POS systems have required a certified TSE under KassenSichV and must store data in a GoBD-compliant manner. Since 2025, there has also been a reporting obligation to the tax authorities via ELSTER. From 2027, a mandatory cash register requirement for businesses with annual revenue of more than EUR 100,000 is also under discussion, but the law has not yet been finally adopted.
Buying or renting a POS system – which is more worthwhile for retail?
Most of the systems presented are offered on a subscription model rather than as a fixed purchase. This has the advantage that TSE updates, maintenance and new functions are automatically included. A one-off purchase with your own hardware is usually only worthwhile if your requirements are very stable, long-term and unlikely to change, with no planned growth.
Which POS system is suitable for a fashion shop with inventory management?
For fashion shops with many size and colour variants, Tillhub by Unzer, ready2order, SumUp and ETRON each offer functions for managing item variants. Lightspeed Retail works with custom tags for brand, colour and size to make large product ranges searchable. Tillhub by Unzer also offers stock balancing across branches, for example to move goods between locations depending on demand.
