Custom Shopware plugin instead of a subscription: the math
by Marcel, Senior software engineer
If you run a Shopware store, you know the drill: there's a plugin for almost every extra feature — and a lot of them charge a monthly or yearly fee. Taken one at a time, that looks harmless. Added up and stretched over the years, it turns into a quiet, permanent cost block. Let's look at when building your own plugin makes more sense instead.
The problem with subscription plugins
Subscription plugins come with three catches that tend to get lost in day-to-day business:
- They cost you forever. As long as you need the feature, you keep paying — with no end in sight.
- They never belong to you. Cancel the subscription and the feature is gone.
- You're dependent. If the vendor drops support or discontinues the plugin, you have a problem.
On top of that: a subscription plugin often does ninety percent of what you need — but not the one thing you actually asked for. So you're paying indefinitely for a solution that doesn't quite fit.
The math
Take a typical subscription plugin at €49/month. That's €588 a year. Over five years: €2,940 — and you own nothing at the end of it.
A comparable custom plugin usually lands in the high three-digit to low four-digit range, depending on the feature — one time. Even if it costs a bit more upfront than a year of subscription fees, it's usually cheaper after one to two years. From then on, you save real money every single month.
Top tip
Rule of thumb: if you're paying more than €30–40 a month for a plugin and you need the feature permanently, it's almost always worth looking at your own solution.
What speaks for your own plugin
- A one-time cost instead of recurring fees.
- It belongs to you — no vendor can take it away.
- It fits exactly: we build precisely the feature you need, with no dead weight.
- Update-safe: we build your plugin to the official Shopware standards so it survives future updates too.
When a subscription still makes sense
Honest is honest: for features that need constant maintenance — integrations with third-party services that change frequently, for example — a subscription can be the smarter call, because the vendor handles the ongoing upkeep. That's exactly what we look at together with you before we build anything.
How we work
You tell us which feature you're missing or which subscription plugin you want to replace. We estimate the effort, weigh it against your running costs, and tell you honestly whether your own plugin is worth it for you. You can take a calm look at how a project like this works step by step beforehand.
