Checkout & payments
Payment Integration
The most common reason carts get abandoned? The payment step. That's exactly where we start.
We integrate Klarna, PayPal, Stripe, credit cards, Apple Pay and more into your shop or website — reliable, secure and built so the checkout converts instead of scaring customers away.
Why professional payment integration?
Payments are where trust, technology and law meet. Done well, nobody notices them. Done badly, they cost you completed sales every single day.
Fewer abandoned checkouts
Missing payment methods and clunky flows are top abandonment drivers. The right payment mix meets customers where they already pay.
The right payment mix
Klarna, PayPal, credit card, Apple/Google Pay, SEPA, purchase on account — which methods you need depends on audience and basket size. We advise based on data.
Secure & compliant
PSD2 strong customer authentication, PCI-compliant processing and GDPR-clean data flows — set up correctly instead of bolted on later.
Reliable in the ugly cases
Failed payments, refunds, chargebacks, webhooks that arrive twice — we engineer the edge cases so your books stay clean.
