What Magento 2 Extension Development Services Do We Offer?
We provide a full range of extension development services — from custom Magento extension development and enhancements to compatibility checks and integration into a live store.
Custom extension development
We build Magento modules from scratch when your store needs features that existing solutions do not provide.
Our custom extensions can extend the capabilities of the admin panel, automate routine tasks, or expand storefront functionality to meet customer needs.
Commercial Magento 2 extension development
We develop commercial extensions for distribution through the Adobe Commerce Marketplace.
Our work covers extension development, supporting documentation, and Marketplace submission, including the required revisions if the review team requests changes before approval.
Third-party extensions customization
We adapt ready-made Magento extensions when an existing module covers part of the need but requires changes to fit your requirements.
Our developers can extend the module’s logic or perform module refactoring when the code structure affects website performance.
Extensions compatibility enablement
Whidegroup developers perform urgent and upgrade compatibility checks to identify conflicts that affect storefront features or admin panel operations.
After determining the cause of the conflict, we implement the adjustments to restore proper website behavior.
Magento extensions migration
We adapt Magento extensions when migrating from Magento 1 to Magento 2 or changing the storefront theme to Hyvä.
Whidegroup developers review the existing modules and update the code so the required functionality works after the migration.

FAQs About Magento Extension Development Services
How can custom Magento extensions improve my store’s performance?
Custom Magento extensions can improve store performance when they replace overloaded third-party modules, remove unnecessary logic, or optimize how specific features work within your Magento environment.
More broadly, modules designed for your store can optimize database operations, automate repetitive tasks, and help the store handle higher traffic and order volumes.
Can you integrate your custom extensions with my existing tools and software?
Yes. We first review the integration points and existing dependencies. Based on this audit, we build module logic according to your current store architecture.
Does a custom extension slow down my Magento website?
Not necessarily. Speed depends on how the extension interacts with Magento, the database, APIs, and other modules. We consider these dependencies during development and test the extension within your store environment to identify possible issues.
How long does it take to develop a custom extension?
The development timeline depends on the extension’s functional scope and existing store complexity. Simple extensions may take a few days, while complex modules with custom business logic or multiple integrations can take several months.
Does my extension require constant updates or adjustments?
A custom extension does not usually require constant changes, but you may need adjustments when Magento, PHP, third-party services, or related extensions receive updates. We can also adjust the extension when your business processes or functional requirements change.
What’s the cost of developing a custom Magento module?
Costs depend on the project’s scope and the complexity of the features you need. Development of simple modules starts at $1,000 and can exceed $9,000 for complicated solutions. We estimate the budget after analyzing your requirements and existing store architecture instead of using a fixed price for all modules.
Who owns the source code upon completion, and do you sign an NDA?
You retain 100% ownership of the custom source code, intellectual property, and all associated assets upon project completion.
We always prioritize client confidentiality and are ready to sign a non-disclosure agreement (NDA) or other legal documentation required by your internal policies to guarantee the protection of your proprietary information.
Do your custom extensions comply with Magento 2 Coding Standards and security requirements?
Yes, we develop extensions according to Magento coding standards and apply security hardening practices during implementation. We review the extension for compatibility with the target Magento version and test its interaction with the store environment. For commercial extensions, we also account for Adobe Commerce Marketplace requirements.
Can you help us prepare the extension for submission to the Adobe Commerce Marketplace?
Yes. We provide a complete service for the marketplace submission. We conduct a comprehensive technical audit to ensure your extension meets all Magento coding standards (M2), passes the technical review criteria, and complies with security requirements. We complete the required documentation and ensure the extension passes all validation steps.
