WHAT WE BUILD

Custom Magento
Extensions
Built to Adobe Standards

We don't patch existing extensions or copy-paste solutions. Every module we write is architected from the ground up — clean service contracts, proper dependency injection, and a full test suite you can run on any future Magento version.

Whether you need a payment gateway integration, a custom B2B workflow, a complex pricing engine, or a data pipeline — we've built it before at production scale.

HOW WE WORK

Our Extension Development Process

No wireframe-to-code chaos. Every extension follows a 6-phase framework designed to catch issues before they cost you time.

01 1-2 days

Requirements Spec

We document every functional and technical requirement before a single line is written. No guessing.

02 2-3 days

Architecture Design

Module structure, database schema, API contracts, and integration points — all planned upfront.

03 Ongoing

Test-First Development

We write unit and integration tests before building features. Bugs get caught before QA.

04 Continuous

Code Review

Every PR reviewed by a senior engineer against Magento coding standards and SOLID principles.

05 3-5 day

QA & Compatibility

Tested on multiple Magento versions, PHP versions, and against common third-party extensions.

FAQ

Extension Development FAQ

The timeline depends on the extension’s complexity, features, integrations, and testing requirements. Simple extensions may take a few weeks, while more complex solutions can take several months. We define the scope and provide a clear development timeline before starting.

Yes. We design custom extensions to work with your existing Magento setup and third-party modules wherever possible. Our team reviews your current environment, identifies potential conflicts, and tests the extension thoroughly before deployment.

Yes. We can help prepare and submit extensions for the Magento Marketplace, including technical requirements, documentation, code quality, testing, and submission support. We can also develop extensions specifically with Marketplace requirements in mind.

We provide post-launch support to address bugs related to the agreed functionality. If an issue is identified after delivery, our team investigates the cause and works to resolve it as quickly as possible. We can also provide ongoing maintenance and support for continued improvements.

Yes. We can take over existing Magento extensions developed by another team or agency. We first review the code, architecture, compatibility, and known issues before recommending improvements, fixes, or further development. This helps ensure a smooth transition without unnecessarily rebuilding what already works.
