Payment integrations
Adyen integration for online and in-store sales
We integrate Adyen for high-volume businesses that sell online and in physical stores and want everything on one payment platform. The website, the app and the store terminals then share the same reports and the same history for each customer. It mostly suits retailers with several stores, operations across several countries and companies that have outgrown simpler options.
One platform for every channel
Adyen brings website, app and in-store payments into a single account. For the business, that means one sales report, one reconciliation and the same customer recognised across every channel. For the customer, it means buying online and collecting in store, or returning in a shop something they bought on the website, without any fuss.
The payment methods are the ones the market expects: cards, Apple Pay, Google Pay and, for Portugal, MB WAY and Multibanco. In each country you sell to, we switch on the local methods that matter there.
The integration work
In an online store, the Adyen checkout sits inside your page, in your own design, and shows each customer the methods of their country. In physical stores, we connect the terminals to the till software, so the amount goes from the system to the terminal without being keyed in by hand.
Adyen's webhooks keep everything else up to date: payments authorised, captured, declined or refunded. Settlement reports can flow into accounting or the ERP through integrations and APIs, which saves hours of reconciliation at month end.
When it makes sense
Adyen pays off when volumes are high, there are several channels or countries, or the business needs fine control over processing. For smaller stores, other options reach the same result faster. If you need one-tap mobile checkout, see also Apple Pay and Google Pay.

Frequently asked questions
Is Adyen right for a small business?
It usually isn't the first choice. Adyen is built mainly for high-volume businesses. For a store that is just starting, Stripe or a Portuguese provider is usually simpler to get running.
Are the website and the store terminals connected?
Yes. Online and in-store payments land in the same account and the same reports. A customer can buy on the website and return in a store, and the refund goes back the same way the original payment came in.
How do Adyen's fees work?
Adyen's fees apply, and they depend on the payment methods and the volume. We explain the ones that apply to you in the proposal. Our own work is on request, quoted for each project. Request a quote
Can we move to Adyen from another provider?
Yes. We plan the move in stages, with both providers live during the transition. Saved cards can be migrated when both providers support it, so customers don't have to enter their details again.
