Stripe Partner

An official Stripe partner
based in Germany

KOMMERS is part of the Stripe Partner Ecosystem and holds 4 Stripe certifications. We build checkout, billing and payouts in WooCommerce, Shopify, Shopware and custom software, from the first payment through to your accounting.

Stripe is financial infrastructure for the internet. Our job is to translate that infrastructure into your shop: the right payment methods per country, webhooks that hold up under load, subscription logic that survives edge cases, and numbers that reconcile at the end of the month.

What the partnership means for your business

Live in weeks, not quarters

Checkout, payment methods and tax logic already exist. We assemble what Stripe provides instead of rebuilding every rule, so your shop starts selling sooner.

Sell in new markets

Local payment methods, currencies and tax handling your customers recognise from their own country, without a second shop and without a second checkout.

Build recurring revenue

Subscriptions, usage-based pricing, invoices and dunning. We build price models you can change later without touching the shop.

Fewer manual steps

Payments, shop, ERP and accounting talk to each other. Less exporting by hand, fewer surprises at the end of the month.

Certified by Stripe, verifiable by you

These certifications are exams our team passed at Stripe. All 4 are issued by Stripe and publicly verifiable, and every entry links straight to the credential.

What we build with Stripe

Checkout integration

Stripe in WooCommerce, Shopify, Shopware or your own application: payment methods per country, saved cards, wallets and a checkout that survives a failed payment.

Subscriptions and billing

Recurring plans, trials, upgrades, proration, invoices and dunning with Stripe Billing, including the edge cases that decide whether customers stay.

Marketplaces and platforms

Onboarding for your sellers, split payments, commission and payouts with Stripe Connect, built so that adding a seller stays a self-service step.

Migration to Stripe

Moving from another provider, including live subscriptions and stored payment credentials, so recurring customers keep paying without re-entering anything.

Fraud prevention and SCA

Stripe Radar rules, 3D Secure and strong customer authentication tuned so that genuine orders get through and chargebacks stay rare.

Reporting and accounting

Payouts, fees, refunds and taxes reconciled against your ERP and your accounting, so the month-end close matches the shop without a spreadsheet.

Frequently asked questions about our Stripe partnership

What does it mean that KOMMERS is a Stripe partner?

KOMMERS is part of the Stripe Partner Ecosystem, the official programme Stripe runs for agencies and implementation firms. It means Stripe has verified us as an implementation partner and that we work with the same documentation, release information and support channels Stripe gives its partners. KOMMERS remains an independent company: the partnership is not a joint venture, and we are not employed or controlled by Stripe.

Which Stripe certifications does your team hold?

Our team currently holds 4 Stripe certifications: Professional Payments Architect, Professional Payments Developer, Professional Billing Developer and Professional Platform Developer. Every certificate is publicly verifiable, and each one is linked from this page so you can check it yourself rather than take our word for it.

Do you work with WooCommerce and Shopify, or only with custom software?

Both. Most of our work runs on WooCommerce and WordPress, which is where we have the deepest experience, and we also build on Shopify, Shopware and custom applications. The payment layer is the same in every case: the same checkout logic, the same webhooks and the same reconciliation with your accounting, adapted to the system you already run.

Can you migrate an existing shop to Stripe?

Yes. We migrate existing shops, including live subscriptions and stored payment credentials, so that recurring customers keep paying without having to re-enter their details. We plan the migration in a staging environment first, run both systems in parallel where that makes sense, and only switch the live traffic once the numbers reconcile.

Is a Stripe setup GDPR-compliant for a German business?

It can be, and that is part of the work. We look at where data is processed, what your checkout and tracking actually transmit, which consent your cookie banner has to collect, and what belongs in your privacy policy and your processing records. You get a German company as your contractual partner and a documented setup you can show to your own data protection officer.

How does a project with you start?

It starts with a payments check. You tell us in a few sentences what you sell and which system you run, and we come back within 24 hours with an honest assessment: what your current setup costs you in failed payments and manual work, what we would change first, and roughly what that takes. No sales call unless you ask for one.

Tell us in two sentences what you sell

Within 24 hours you get an honest assessment of which platform fits and what range the project sits in.

No sales call without your go-ahead. We reply in writing, with a name and a direct line.
