Checkout without trauma

LEAN Operations: eCommerce and Payment Integration

We build complex eCommerce solutions and integrate payment gateways like Stripe, Adyen, or Mollie so that payments are actually processed. Whether it's a single or multi-tenant shop - we got you covered!

What's it about?

For shops that lose customers at every checkout step and have outgrown their standard platform. For teams that need cleanly integrated payment logic.

Your benefit:

  • Conversion Rate ↑
  • Payment Flexibility ↑
  • Abandoned Carts ↓

Do you know?

The checkout drives customers away

Too many steps, long loading times, unclear error messages.

Mobile users abandon disproportionately because the flow isn't designed for small screens.

Payment integration is fragile or limited

One payment provider, no fallback logic – if it fails, revenue fails.

Integrating new payment methods takes months instead of days.

Shop logic is stuck in the platform

Cart, discount logic, product catalog are tied to a SaaS tool that no longer scales.

Every special requirement (B2B pricing, tiered discounts, coupon logic) becomes a workaround.

What does this bring you?

Fewer abandoned carts

Checkout flow optimized for conversion: minimal steps, fast loading times, clear error communication. Mobile-first, A/B testing capable, performance optimized.

Flexible Payment Integration

Stripe, Adyen, Mollie, or others: payment gateways cleanly integrated, with fallback logic and support for all relevant payment methods. New methods in days instead of months.

Shop logic that fits your business

Out of the box, you get everything a shop needs with Vendure – product catalog, cart, discounts, coupons. All open source, all expandable, and what’s missing, we build custom.

Measurable Results

Conversion rate, abandonment rate per step, payment success rate – all tracked and optimizable. Data-driven decisions instead of gut feeling.

Pilot Phase

Deliver first, then commit. That’s what the pilot is for.

  • Duration

    6-10 weeks

  • Assessment

    What products are being sold? Which payment methods are relevant? What tax and shipping logic needs to be represented? Where are you currently losing customers in the checkout flow?

  • Derived from this

    Project scope, shop logic, payment strategy

Deliverables

  • Setup and basic configuration of a shop system

    including product catalog with up to 3 products with defined variants and up to 2 tax and shipping rules

  • Storefront Implementation

    with product listing, product detail page, and checkout flow based on a starter template

  • Integration of a payment gateway

    for a complete checkout process

  • Tested and deployed

    for beta testing purposes

Frequently Asked Questions

FAQ
Do you build complete online shops?

Yes, but no Shopify themes. We build custom eCommerce solutions – product catalog, cart, checkout, payment – on your stack, for your requirements. If a SaaS platform is enough for you, we’ll tell you that too.

Which payment providers do you support?

Stripe, Adyen, Mollie, PayPal, Klarna – and anything with an API. In the pilot, we start with one provider, in scale we add more – including fallback logic, so revenue doesn’t stop if one fails.

Can we keep our existing shop?

Depends on where the problem lies. If the shop works and only the checkout or payment integration is problematic, we optimize specifically. If the platform is the bottleneck, we rebuild the shop logic – step by step, not as a big bang.

How do you improve the conversion rate?

By reducing steps, speeding up loading times, providing clear error messages, and mobile-first design. In the pilot, we build the flow, in scale we measure and optimize via A/B testing. Every checkout step is tracked – you see exactly where customers drop off.

What about B2B eCommerce?

That too. Tiered discounts, customer-specific pricing, approval workflows, ERP integration – B2B checkout has different requirements than B2C, and we know both worlds.

What is the pilot phase?

A clearly defined project with a defined scope – typically 4–12 weeks. You don’t get a concept paper at the end, but a functioning result: real code, tested and deployed. The pilot shows you what we can do before you decide long-term.

What happens after the pilot phase?

After the pilot comes the proof: We look together at the results – what worked, what was worth it, where are the gaps? Everything measured against defined KPIs, not gut feeling. Based on this, you decide: scale, adjust, or stop. No pressure, no upselling. If the proof convinces, we go into scale – your project grows, your team grows with it, the knowledge stays with you.

Do I have to start with a pilot phase?

No. The pilot is our recommended entry point because it provides clarity for both sides – but it’s not a must. If you already know what you need and want to get started right away, we can also join an ongoing project or start directly with a larger scope. We adapt to your pace.

Do you work T&M or fixed price?

Start as a timeboxed pilot in T&M (optionally with a cap). No fixed price risk, no lock-in. You see at any time what you are paying for – and can stop anytime. But few do.
