Shopware 6 extends cleanly as long as you respect its architecture: entities declared in the DAL, versioned migrations, events and subscribers instead of overrides, Administration in Vue 3 since 6.6. Plugins that bypass these rules break with every minor release. We build custom Shopware 6 plugins and apps that follow the platform's framework, with a written scope and a fixed price agreed before we start.

We also publish a catalogue of around thirty Shopware plugins (ZUGFeRD and XRechnung e-invoicing, Odoo connector, GPSR compliance, a page builder for 6.7…), tested on versions 6.5 to 6.7. Every custom development follows the same rules.

## Plugin or app: the right format for your shop

Shopware offers two ways to extend a shop. The choice depends on your hosting and on what the extension has to change:

| Format | When to use it |
| --- | --- |
| Plugin | Self-hosted or PaaS shop. Full access to the core: entities, services, subscribers, cart calculation. The most common format for B2B and heavy integrations. |
| App | Shopware SaaS shop, or an extension meant for several merchants. The logic runs on an external server and communicates via webhooks and APIs; the core cannot be changed directly. |

We tell you which format fits during scoping, before any quote.

## What we build on Shopware 6

### Administration and business tools

Administration modules in Vue 3 with Meteor components, list and detail views with bulk actions, structured custom fields, new conditions in the Rule Builder and new actions in the Flow Builder so your team can automate without code.

### Storefront

Blocks and elements for Shopping Experiences, Twig template extensions, Storefront JavaScript plugins. Everything can be overridden by your theme and works with the HTTP cache.

### Cart, pricing and payment

Cart processors and collectors for specific pricing rules, surcharges, shipping restrictions, payment handlers for a PSP not covered in the store.

### Integrations

ERP, PIM, 3PL, e-invoicing. Exchanges run through the Symfony message queue and scheduled tasks, with logging and retries on failure. For a wider B2B need, see our [Shopware B2B](https://www.datafirefly.com/en/expertise/shopware-b2b-store/) page.

## How we write a Shopware plugin

- **Entities declared in the DAL** with definitions, associations and versioned migrations, so data is available through the Admin API and Store API.
- **Events and service decorators** instead of changes to core files.
- **Administration in Vue 3** for all new work, compatible with 6.6 and 6.7.
- **Heavy processing done asynchronously** through the message queue, so an order is never blocked.
- **Translations included** for the languages of your sales channels, Storefront snippets included.

## What you receive at delivery

- The plugin as an installable ZIP, tested on your Shopware version and your staging environment.
- The complete source code with no restrictive licence.
- Installation and user documentation.
- 12 months of compatibility updates and bug fixes.

## What drives the price of a Shopware plugin

Our quotes start at €2,000 and stay fixed once the scope is approved.

| Factor | Effect on the quote |
| --- | --- |
| Administration | A simple configuration, or a full Administration module in Vue 3. |
| New entities | Each entity adds a definition, migration, translations and management screens. |
| Cart and order | A Storefront display is quick; a rule that changes cart calculation is tested against every combination of rules and sales channels. |
| Versions | Targeting 6.7 only is faster than covering 6.5, 6.6 and 6.7. |
