What plugs in

Four integration areas.

Everything outside the catalogue connects through these four pillars. Pick what you need on the brief — we wire it up.

Slovak standard

QR Pay by Square + IBAN.

Slovaks pay by scanning a QR with their banking app. Shopify doesn't do it natively. We bake it into checkout — the QR is generated per order, with a SEPA reference that auto-matches the incoming payment.

QR / IBAN · SEPA · auto-matching
Marketing tool

Push notifications for e-shops.

Automated notifications straight to the browser or mobile — no email required. Abandoned cart, discounts, order status. Higher open rate than email, zero spam filter.

Why pure code

What you give up with Shopify.

Real numbers. Over six months at €10,000 monthly revenue, you can do the maths yourself.

How it goes

Four phases to launch.

  1. Week 1

    Audit & catalogue

    We review your range, couriers, payment gateways. We design the product object schema, the URL map, the redirect map from your old store.

  2. Week 2 – 3

    Build & integrate

    Front-end + admin panel. Payments wired (including QR IBAN), couriers, email and notification channels. First end-to-end test checkout.

  3. Week 4

    Test & soft launch

    We invite an internal circle to place real orders. Edge cases get tuned, payment matching verified. Mobile checkout UX test.

  4. Post-launch

    Iteration & growth

    Analytics, abandoned-cart campaigns, checkout A/B testing. Quarterly addition of more channels and marketing flows as needed.
