Best POS for Retail Stores: Types, Fees and Integrations
The best POS for retail depends on three things: where the payment happens, how big the ticket is, and what software it must talk to. A fashion boutique, an electronics store and a pop-up stand need different hardware, but the fee model matters even more than the terminal: on 20,000 euro per month, every 0.1% saved is 200 euro per month. This guide compares POS types and shows why per-card pricing beats flat rates.
POS Types for Retail: How to Choose
Counter POS: for shops with centralized checkout (apparel, electronics, jewellery, beauty). A customer-facing screen with integrated pinpad and printer is the standard.
Portable smart POS (Android): payments happen where the customer is: fitting room, showroom, in-store pickup counters.
Mobile reader: Bluetooth reader plus smartphone app for markets, pop-up stores and itinerant sellers. For phone orders, a [virtual POS](/en/resources/virtual-pos) on a laptop replaces the terminal entirely.
EPOS integrated with stock software: retail chains run the POS inside the cash management system (Lightspeed and Shopify POS-class environments), so inventory, loyalty and payments stay in sync.
Retail POS Fees: Flat Rate vs IC++ on Real Numbers
Flat rate: SumUp charges 1.69%, Square about 1.65%, PayPal 1.75%. Simple, but it ignores what each card really costs: a Visa Debit in the EU carries about 0.20% interchange, while premium consumer credit tiers carry 0.30% to 1% or more depending on the scheme.
IC++ (Interchange++): you pay the real interchange of each card plus a fixed markup. It wins for:
- shops with heavy debit volume,
- premium retail where the real card cost is passed through instead of a padded flat estimate,
- any shop above roughly 10,000 euro per month in card volume.
RoxPay: €0.15 + 0.35% to 0.85% (IC++). On a low-interchange EU Visa Debit the total lands well under the SumUp flat 1.69%, because the fee follows the actual cost of that card.
Integration with Cash Management Software
Lightspeed Retail: integration available; it is the stock software preferred by premium independent boutiques.
Shopify POS-class environments: for shops with online and physical presence, the terminal folio syncs with the online catalog inventory.
National EPOS suites: integration via API or plugin for regional retail management systems; contact support for the configuration.
The goal is one cash session: sales, payments and refunds post into the same report without end-of-day reconciliation by hand.
Accepting International Cards in Retail
Visa and Mastercard international: accepted by default on every terminal account.
American Express: include it in the standard range: US and business customers expect to find Amex in a premium store.
UnionPay: relevant in locations with Chinese customers (tourism, students, business travel).
JCB: available on request for Japanese customers.
A shop that refuses Amex or UnionPay loses the whole basket, not just the fee: the customer goes to the next door that takes the card.

Frequently Asked Questions
How much does a retail shop save with IC++ vs SumUp or Square?
On 30,000 euro per month with a 60% debit share, moving from a 1.65-1.69% flat rate to per-card pricing with a low-interchange debit mix typically cuts the fee bill by several hundred euro per month. The exact saving depends on the share of debit cards in the mix.
Does the POS work without internet?
Yes: a 4G-equipped Android smart terminal keeps processing payments without shop WiFi and syncs the transactions when the connection returns.
Can I have more terminals for a multi-register store?
Yes: each register runs its own terminal independently and all of them roll into one settlement report and one merchant account.
What happens when I need to reverse a payment?
Terminal-level voids work before settlement; after settlement you issue full or partial refunds from the dashboard. Card schemes do not always refund the interchange component on processed refunds, so it shows up as a small net cost on reversed transactions.
Rent or buy a retail POS terminal?
For a single-counter shop the hardware choice matters less than the fee structure. See the [POS rent or buy comparison](/en/resources/pos-rent-vs-buy-which-is-better) for the break-even math.
