Custom Magento extension development for your business
What Magento extensions do
Magento module development adds functionality beyond Magento's core features. You can buy them on the Magento Marketplace, download free ones, or have them built. The extension layer is what turns a standard installation into a store shaped around your business.
Buy or build: our honest recommendation
We typically recommend buying an existing extension when one fits. Chances are someone already built what you need, and commercial extensions come from companies working full-time on Magento, with ongoing updates and bug fixes that track the platform's evolution. Buying is usually cheaper than funding development from scratch, and we'll say so when it is.
We advise against modifying purchased extensions. Modifications break when the original developer releases updates, creating technical debt and upgrade risk. Unless it's genuinely unavoidable, keep purchased extensions clean.
Custom development is the right call when nothing on the market matches. Then you get functionality built precisely to your specification, no workarounds, complete control, an architecture that grows with you, and ongoing support from the team that built it.
What we build
Payment integrations, shipping and tracking, ERP connections, one-step checkout optimization, gift card systems, advanced caching, SEO tooling, and analytics integrations, among others: effectively any functionality your store requires.
How extension development works
Our Magento extension developer team starts by understanding your business requirements and technical environment, then architects a solution that integrates with your existing Magento setup without compromising performance or security. You receive progress updates and feedback opportunities throughout, QA testing verifies the extension before deployment, and you get documentation and ongoing support after launch. The whole engagement runs at a fixed price, approved by you before work begins.
Our own Magento extension: WriteText.ai
We build extensions for ourselves too. WriteText.ai, our AI product content solution, generates meta titles, meta descriptions, product descriptions, Open Graph texts, and image alt texts, all inside Magento. If product content is your bottleneck, it's worth a look.
Two ways to work with us
Continuous Monthly Development: Send tasks whenever they arise. With Care, everything runs in writing at one fixed monthly price: no estimates to approve, no cost overruns.
Care Plus gives you everything in Care at its own fixed monthly price, plus up to two hours of meetings per month with a Project Manager or any 1902 Software expert (for planning, advice, and technical discussion), up to two ongoing tasks at a time, and up to two developers working on your tasks at the same time.
Care Ultimate is for ongoing engagements, often across multiple systems, that need close collaboration: a fixed price for every task or group of tasks, approved by you before work begins, people with the right expertise added to your project as your needs grow, and meetings with any 1902 Software expert whenever you need them (billed at the going project management rate for the actual time spent).
Fixed Price Projects: For a single, well-defined Magento project (a new build, a major upgrade) you get one agreed price for the whole thing, fixed before work begins.
Large projects typically start with a Project Scoping phase at an agreed, prepaid fixed price. The purpose is to precisely define what will be built and to establish the final price. This ensures full clarity for both you and us before development begins.
How we use AI
AI-assisted tools are part of how our Magento developers work through development and testing. Every extension is still reviewed, tested, and verified by experienced developers and QA testers before deployment.
Free, no-commitment
Commonly asked questions
Should I buy an extension or have one built?
Buy when an existing extension fits: it’s cheaper and comes with the original developer’s updates. Build when nothing on the market matches your requirements. We’ll tell you honestly which situation you’re in.
Can you modify a purchased extension?
We advise against it unless absolutely necessary; modifications tend to break when the developer releases updates. Usually the better path is a separate custom extension alongside the purchased one.
What does custom extension development cost?
A fixed price, agreed before work begins, based on the scope we define together.
Who supports the extension after launch?
The team that built it, through Continuous Monthly Development, so upgrades and Magento version changes are handled by people who know the code.
Will a custom extension survive Magento upgrades?
That’s the goal of building it properly: clean architecture, no core modifications, and the team that built it handling upgrades through Continuous Monthly Development.
Can you fix or extend an extension another company built?
Yes. We review the code first, tell you what shape it’s in, and quote the work at a fixed price before anything starts.
