Custom Magento 2 and Adobe Commerce extensions, built to survive upgrades. Fixed-scope pricing, and an honest answer on whether to just buy one instead.
Base scope of work — applies to all tiers. See the tier comparison below for hours and SLA specifics.
Built with plugins, observers, and dependency injection instead of core overrides, so it survives the jump from one Magento 2.4.x release to the next.
Settings live in the normal Magento admin under System > Configuration, not a bolted-on panel your team has to learn separately.
We test on a copy of your store, including the upgrade path, so you find out it works on staging, not in production at checkout.
You get the full source, install instructions, and a plain-English note on what it does. Any Magento developer can maintain it later.
Custom code that runs on every page load gets profiled. An extension that adds 300ms to your cart isn't done, it's a regression.
If a Marketplace extension from Amasty, Mageplaza, or Mirasvit covers your need for a fraction of a custom build, we say so before you spend.
Transparent process — you always know what stage we're at and what comes next.
We pin down exactly what the extension must do and check whether a Marketplace module already does it. If one does, the project may stop here, and that's fine.
You get a written scope and a fixed price before any code is written. No hourly meter running in the background.
We develop against a copy of your store, to your Magento version, with the upgrade path in mind from line one.
We test, hand over source and docs, and deploy to production with you. The 90-day warranty starts at go-live.
Pick the level that fits your size and required response time. You can switch tiers between months.
One focused piece of functionality: a custom shipping rule, a checkout tweak, an admin tool. Self-contained, no external integration.
An extension that talks to an outside system: ERP, CRM, PIM, payment, or shipping carrier. The most common request we get.
An extension you intend to sell or distribute, built to pass Adobe Commerce Marketplace review and the Extension Quality Program.
Scope transparency — no surprises in the monthly report.
Access we require — passed via secure channel (1Password / Bitwarden).
A single self-contained extension starts around $3,000. An integration extension that connects Magento to an ERP, CRM, or carrier runs about $8,000 to $15,000, and a commercial extension built to pass Adobe Marketplace review starts near $18,000. We quote a fixed price against a written scope before any code is written.
Buy when a Marketplace extension from Amasty, Mageplaza, or Mirasvit already covers your need; a $150 to $400 module beats a custom build every time for common features like SEO, one-step checkout, or blog. Build custom when the logic is specific to your business and no module fits. We check the Marketplace first and tell you honestly.
In practice they’re the same thing. A module is the technical unit of code Magento loads; an extension is usually a module (or a few) packaged and distributed, often through the Marketplace. When people say extension they mean a module that adds a feature. We build both, by either name.
Not if it’s built properly. The extensions that break on a 2.4.7 to 2.4.8 upgrade are the ones that override core classes. We use Magento’s plugin (interceptor) system, observers, and dependency injection, which are the supported extension points designed to survive upgrades. We also test on the target version before handover.
Yes. A lot of our extension work is rescuing modules that override core, fail on upgrade, or slow the store down. We audit what’s there, tell you whether it’s worth fixing or cheaper to rebuild clean, and quote either way.
Yes. The extension architecture is the same across Magento Open Source and Adobe Commerce, so a well-built extension works on both. If your feature touches Adobe Commerce-only functionality like B2B company accounts, we build against that edition specifically.
Before we quote any Magento extension development, we ask one question: does this already exist on the Adobe Commerce Marketplace? Half the time it does, and a $200 Amasty or Mageplaza extension will do what you need without us writing a line of code. We’ll tell you when that’s the smarter buy. Custom extension development is for the other half: the logic that’s specific to how your business runs and that no off-the-shelf module covers.
When we do build, the rule is simple: it has to survive the next Magento upgrade. Plenty of agencies ship extensions that override core classes and shatter the moment you move from 2.4.7 to 2.4.8. We build with plugins, observers, and proper dependency injection so your custom code keeps working when the platform moves under it.
Before commissioning custom code, check whether an off-the-shelf option already does the job. Here are the Magento extensions we actually install.
90-day warranty from go-live. If the extension breaks on its own or doesn’t do what the scope said, we fix it at no charge.
