Plugin developmentthat fits your model

Standard plugins cover 80 percent. The last 20 percent is usually what actually makes your business unique. That's exactly what we build custom plugins for – clean, tested and documented.

Three marketplace plugins that don't talk to each other, plus two custom patches in the theme and a forgotten update – and suddenly checkout is broken. Once your model is B2B-specific, regulatory or commercially unusual, a proper plugin pays off faster than another workaround.

Three marketplace plugins fight each other and checkout is broken.

A plugin update regularly kills features that worked yesterday.

Our business model simply doesn't fit a standard plugin.

Nobody remembers which patch is stuck where in the theme.

What matters for Plugin development

The first thing that matters is the honest question of whether you even need a plugin. As long as a marketplace plugin does its job cleanly, we won't rebuild it. Only when your model is B2B-specific, regulatory or commercially unusual does a custom build pay off more than the next workaround. We estimate effort and risk openly upfront instead of talking you into an expensive special solution.

When we do build, update safety comes first: no core hacks, clean extension points and an architecture that survives the next Shopware release. Tests and documentation matter just as much, so you're never dependent on us but understand and own the code. We integrate consistently across the admin (Vue) and the storefront (Twig), so the plugin feels like a native part of your shop – whether it's about B2B order processes, customer-specific price lists or ERP-driven listing views.

How we build plugins

Clean plugin architecture

We use Shopware's official extension points: subscribers, entities, migrations, custom fields, API endpoints. No core hacks, no theme overrides for logic.

Tests and documentation

Every plugin ships with unit tests, README, changelog and sensible config options. You should still understand it when we're not around.

Admin and storefront integration

We build matching administration modules with Vue.js and storefront components with Twig – consistent with Shopware's look.

B2B, regulatory, integrated

Price tiers, customer hierarchies, approval workflows, special tax logic, integration with external master data – these are our typical plugin topics.

Plugins that survive updates

We build custom plugins as clean extensions, not patchwork – tested, documented and in your hands.

  1. Zero core hacks

    We extend Shopware through its intended interfaces instead of patching the core. That keeps your plugin update-safe.

  2. Tests and docs included

    Every plugin ships with tests and documentation. You understand the code and aren't dependent on us.

  3. Admin and storefront integrated

    We think backend and frontend together – Vue in the administration, Twig in the storefront. The plugin feels native.

  4. Honest effort estimates

    We tell you upfront whether a custom build is worth it and estimate effort and risk openly – even when the answer is no.

Frequently asked questions

When is a custom plugin worth it instead of a marketplace plugin?
As soon as your model is B2B-specific, regulatory or commercially unusual. Three conflicting marketplace plugins plus theme patches are more expensive and more fragile than one clean custom plugin.
Are custom plugins update-safe?
Yes, if they're built cleanly. We use only Shopware's official extension points – subscribers, entities, migrations, custom fields, API – with no core hacks. That way plugins survive Shopware updates.
What does a Shopware custom plugin cost?
It depends on complexity and integration depth. We sketch effort and risk openly before we start, instead of luring you with a flat rate.
Do I get documentation for the plugin?
Yes. Every plugin ships with unit tests, a README, a changelog and sensible config options – so you understand it even when we're not around.
Do you also develop for the Shopware administration?
Yes. We build matching administration modules with Vue.js and storefront components with Twig – consistent with Shopware's look and interaction model.
