Every market, the right payment options
Whether you operate in one country or ten, S4D supports the payment methods your customers expect.
Payment Provider Integrations
One payment layer across your entire chain.S4D integrates with leading payment service providers, so every sales channel accepts the right payment methods for every market, configured centrally by headquarters.
- Adyen, Mollie preferred providers, fully integrated
- Configuration per channel, order type, and market
- Fiscalization and local compliance
Payment provider network
S4D integrates with a broad network of international payment service providers. Our integration partners are Adyen and Mollie, both battle-tested across multi-location QSR chains. If your chain has an existing relationship with another provider, our team will look into it to make sure you can use your preferred payment providers.
Configurable per channel and order type
Different channels can run different payment configurations. For example, cash payments available for takeaway and pick-up but not delivery. Headquarters sets the rules: per channel, per order type, per store or group of stores, and they apply consistently across the chain.
Market compliance & fiscalization
Operating across multiple markets means navigating different fiscal regulations: receipt requirements, tax reporting obligations, and, in Belgium, the mandatory black box registration system. S4D is active across 16 markets, some of which require fiscalization where S4D is fully compliant. When you expand to a new market, you’re not starting a compliance project from scratch.
Local payment methods
A QSR chain operating across multiple markets needs to meet customers where they are. S4D supports local payment methods via the PSP integrations, Wero (formerly iDeal) in the Netherlands, and others, depending on the local markets. The right payment options for each market, without a separate integration project per country.
Payment terminal integration
The S4D POS sends the order amount directly to the payment terminal, no manual retyping, no risk of the amount being entered incorrectly at the counter. The checkout flow is faster for staff and more accurate for every transaction.
Saved payment methods
Customers on your website and app can save their preferred payment method for future orders. One tap at checkout, no details to re-enter. Lower friction at the moment that matters most, when a hungry customer is about to confirm their order.
Payment centralisation
Running all your online and in-store payments through one integrated layer gives your chain more than visibility, it gives you leverage. Centralised payment volume means better rates from your provider. Every customer gets the same checkout experience regardless of channel. And headquarters gets a clear view of payment mix, transaction volumes, and revenue across every store and market, without pulling reports from separate systems.
Advantages seen by QSR brands that work with us:
Expand markets without a compliance headache
Fiscalization and local tax regulations are handled directly by S4D, including Belgium's black box requirement, Romania's fiscal requirements, and Germany.
Faster checkout, fewer errors at the counter
When a customer is ready to pay, the amount due goes straight from the POS to the payment terminal automatically.
Higher conversion on digital channels
Saved payment methods reduce friction at checkout for returning customers.
Payment data that informs decisions
Transaction data broken down by method, channel, and market gives you visibility into how your customers actually pay.
Freedom to choose your provider
You contract directly with your preferred payment provider, no S4D margin on your transactions.
Access all your data
Most chains are making decisions based on incomplete data, or worse, gut feeling. You can’t fix what you can’t see.
S4D gives you a single view across every location, every channel, every order. Not just dashboards, actual insight you can act on.
What this looks like in practice:
- Preconfigured reports on sales, product performance, and store-to-store comparisons
- Loyalty, coupon, and stock reporting built in
- Power BI integration and custom data requests for deeper analysis
- Data across the full order journey, from first click to delivery
The outcome: You stop guessing which locations underperform and why. You make the call with the numbers in front of you.
