# Custom plugin development for Shopware 6 > Custom Shopware 6 plugins: extensions for processes the standard does not cover. Cleanly encapsulated, update-safe, with a manual. Quelle / Source: https://stoneandwater.online/en/shopware-plugin-development.html # Custom plugin development. When the standard and the store fall short, we build the extension. As a self-contained plugin that installs and uninstalls cleanly. [Discuss your requirement](https://stoneandwater.online/en/contact.html)[Our ready-made plugins](https://stoneandwater.online/en/plugins.html) When it pays off ## When the store *has nothing for it*. Before building something new we check whether it already exists. An existing plugin is almost always cheaper than a custom build. Only when nothing fits does this get interesting. Your processes ### Workflows only you have Approval stages, calculation logic, discount rules or sign-off paths that come out of your business rather than a manual. Interfaces ### Connecting your systems Links to ERP, PIM, CRM or accounting. Import, export, reconciliation - with a log, so it stays traceable when something looks odd. Missing pieces ### Gaps in the standard Sometimes only a small thing is missing in one place. A lean plugin then beats rebuilding the theme. Payment and shipping ### Your own methods Payment methods or shipping rules with no ready-made extension available. How we build ## Encapsulated so it *cannot drag the shop down*. A plugin should install and uninstall without leaving traces. That is not a given, and it is the main reason we build separate extensions instead of touching the core. The core stays core ### No changes to Shopware code We hook in through events, decorators and subscribers. A Shopware update affects the plugin, not the other way round. Sales channels ### Configurable separately Settings can be set per sales channel so one client does not inherit another one configuration. Texts ### As snippets Whatever customers read in the shop lives as a snippet and can be changed without a developer. That covers German and English. Uninstalling ### Cleanly gone Removal tidies up after itself. What data stays is your decision, not an accident. What comes with it ## A plugin without a manual is *half finished*. We do not just deliver code. What belongs to an extension is visible in our own plugins, and the same bar applies to commissioned work. Documentation ### A manual, not guesswork Every plugin comes with instructions explaining what the settings do and what to do when something jams. Admin interface ### Configurable without code Settings belong in the administration, not in a config file on the server. Handover ### The code is yours You get the sources. There is no dependency tying you to us. Ongoing work ### Also after launch Shopware keeps moving. On request we maintain the plugin across version jumps. How it runs ## Understand first, *then build*. The most expensive extensions come from starting to write code too early. 1 - Conversation ### What should come out of it We talk about the goal, not the solution. It often turns out there is a simpler route. 2 - Concept ### Scope and effort You get a written estimate of what will be built and what it costs before effort is spent. 3 - Build ### With interim versions You do not see the plugin only at the end, you can steer along the way. 4 - Handover ### Installed and explained Installation, manual and a walkthrough for the people who will use it. **Discuss a requirement** Tell us what is missing. We will say whether something already exists or a custom extension is worth building.
