Magento Extension Development

Magento Extensions That Add The Feature Without Breaking The Store

A Magento store lives and dies by its extensions. Buy the wrong one and it fights your theme, slows your admin and blocks the next upgrade. We build, customise and repair Magento 2 modules the disciplined way: proper module structure, plugins and observers instead of core edits, and a compatibility check before anything ships. Custom modules for logic no marketplace sells, Adobe Marketplace submissions, and rescue work when a third-party extension has gone wrong.

Who Needs This

Eight Reasons Merchants Come To Us About Extensions

Magento extension development means building, adapting or repairing the modules that add features to your store, without touching Magento core or leaving your next upgrade stranded. These are the eight situations that usually start the conversation.

The Feature Does Not Exist

Your pricing, shipping or workflow rule is specific to your business and no marketplace extension comes close to it.

Extensions Are Fighting

Two modules rewrite the same class or block, and enabling one quietly breaks the other somewhere in checkout.

An Upgrade Broke A Module

You moved to a newer Magento version and a paid extension stopped working, with no vendor fix in sight.

A Bought Extension Is Almost Right

The third-party module does eighty percent of what you need, and the last twenty percent needs proper customization.

You Want To Sell An Extension

You have a module idea for the Adobe Marketplace and need it built to the technical and coding-standard bar for approval.

A Module Is Silently Failing

Something is throwing errors in the logs or slowing the admin, and nobody can tell which extension is responsible.

Too Many Extensions

Dozens of modules from different vendors overlap and duplicate features, and the store has slowed to a crawl.

You Need It Done Cleanly

A past developer installed a module by editing core files, and you want it rebuilt so upgrades stop being a gamble.

Bespoke Or Off The Shelf

Marketplace Extension Or Custom Module

A marketplace extension is the fastest way to add a common feature, and often the right call. A custom module wins when the logic is yours alone or when nothing off the shelf fits. We help you choose honestly, then build or adapt whichever one you pick.

Module Engineers

On every project

	Marketplace Extension	Custom Module
Best For	Common, well-defined features	Logic unique to your business
Time To Live	Fast, install and configure	Built to spec, longer upfront
Fit	What the vendor decided to build	Exactly your workflow, nothing extra
Ongoing Cost	Licence and vendor renewals	One-time build, you own the code
Upgrade Risk	Depends on the vendor keeping up	You control the compatibility roadmap
Customization	Limited, edits fight vendor updates	Open to change without side effects
Code Ownership	Vendor owns and can discontinue it	Yours, documented and handed over
Conflicts	Unknown until installed alongside others	Scoped to avoid class rewrites

Not sure which one your store already relies on? Our Magento code audit lists every extension and tells you honestly which are safe, redundant or risky.

Eight Kinds Of Magento Extension Work We Take On

From a brand-new custom module to untangling a conflict between two you already paid for, this is the extension work our Magento team does every week.

Custom Extension Development

Challenge: your pricing, shipping or fulfilment logic exists nowhere on the marketplace.
Solution: a purpose-built Magento 2 module using plugins, observers and service contracts, never core edits.
Outcome: the exact feature you need, and it survives every upgrade untouched.

Adobe Marketplace Extensions

Challenge: you want to publish a module but it must clear Adobe’s technical and coding-standard review.
Solution: we build to the Marketplace bar, run the EQP checks, and prepare the submission package.
Outcome: an extension that passes review and is ready to sell.

Third-Party Customization

Challenge: a purchased extension is close but the last stretch of behaviour is wrong for you.
Solution: we extend it through plugins and preferences rather than hacking the vendor code directly.
Outcome: the module does what you need without losing its own vendor updates.

Conflict Resolution & Debugging

Challenge: two modules rewrite the same class and something breaks intermittently in checkout or admin.
Solution: we trace the collision, reorder or rescope the plugins, and fix the root cause, not the symptom.
Outcome: both features coexist, and the error log finally goes quiet.

Upgrade & Compatibility Fixes

Challenge: a Magento version bump broke a module, or a paid extension has no compatible release yet.
Solution: we diff the module against the new core, patch the breakages, and re-test critical flows.
Outcome: your extensions work on the new version so the whole upgrade can proceed. See our Magento upgrade service.

Installation & Configuration

Challenge: an extension needs installing on production without downtime and configuring correctly the first time.
Solution: Composer-based install rehearsed on staging, with settings documented and verified.
Outcome: the module goes live cleanly, and your team knows exactly how it was set up.

Extension Audit & Cleanup

Challenge: dozens of modules overlap, duplicate features and drag both storefront and admin down.
Solution: we audit what each one actually does, remove the redundant ones and rationalise the rest.
Outcome: fewer moving parts, a faster admin, and upgrades that stop being a lottery.

Private & Bespoke Modules

Challenge: you need a feature that is a competitive edge and should never sit on a public marketplace.
Solution: a private module built only for your store, documented and version-controlled for you.
Outcome: proprietary functionality that stays yours, with support if it ever needs to change.

How It Fits Together

The Anatomy Of An Extension Built Properly

Every module we write follows the same Magento 2 structure, so any developer can open it years later and know exactly where each piece of behaviour lives. Nothing hides in a core file.

Composer Package

The extension declared as its own package with clear version constraints, installed and updated through Composer.

Module Registration

registration.php and module.xml declare the module and its load order against everything else on the store.

Plugins & Preferences

Behaviour changed through interceptors and service contracts, so core and vendor classes are never edited.

Observers & Events

Side effects wired to Magento events instead of rewrites, so two modules can react to the same action safely.

Admin Configuration

system.xml settings and ACL rules so store managers control the feature without touching code.

Data & Schema Patches

Declarative schema and data patches for any tables or attributes, versioned and reversible.

Automated Tests

Unit and integration tests covering the module’s logic so upgrades can be verified, not just hoped.

Docs & Handover

A readme covering configuration, dependencies and behaviour, handed to your team on delivery.

Quick Answers

Straight Answers, No Sales Pitch

Custom module or a marketplace extension?

If a well-reviewed extension already does the job, buy it and save the budget. Go custom when the logic is unique to your business, when nothing fits, or when you need to own and control the code. We tell you which before any build starts.

Can you fix an extension you did not build?

Yes. Most of our extension work is on third-party or inherited modules: resolving conflicts, patching upgrade breakages, or extending behaviour. We work through plugins and preferences so the vendor can still ship updates.

How long does a custom extension take?

A focused module is usually 1 to 3 weeks. Extensions with admin UIs, data models and integrations run 3 to 8 weeks. A conflict fix or compatibility patch is often a few days. Discovery gives you a real number, not a guess.

Development Process

Eight Stages, Each With A Deliverable

Build

Deliverable: the working module on staging, following Magento coding standards throughout. Timeline: 1 to 6 weeks.

Code Review

Deliverable: a peer review against Magento standards plus PHPCS and Marketplace checks where relevant. Timeline: 1 to 3 days.

QA

Deliverable: a test report covering the module’s flows, conflicts and upgrade behaviour on staging. Timeline: 2 to 5 days.

Deploy

Deliverable: a Composer-managed production release with a documented rollback plan. Timeline: 1 day.

Support

Deliverable: ongoing compatibility care so the module keeps working through future Magento upgrades. Timeline: ongoing.

AI In Development

AI In Magento Extension Development

The slow parts of extension work are rarely the interesting parts: writing the same boilerplate module skeleton, checking a module against a new Magento version, and finding where two extensions quietly collide. This is where we apply AI, with an engineer verifying every result before it ships.

AI-Assisted Module Scaffolding

We use AI to generate the repetitive skeleton of a Magento 2 module, the registration, module.xml, di.xml and directory layout, so our engineers spend their time on the business logic instead of boilerplate a machine can produce correctly.

Compatibility Checking

Before an upgrade, AI-assisted diffing compares a module’s plugins and preferences against the target Magento core so we know which interceptors will break before the upgrade runs, not after it takes the store down.

Conflict Detection

Across a store full of extensions, AI-assisted static analysis maps which classes each module rewrites and where two collide, giving our engineers a shortlist to confirm instead of reading every vendor file by hand.

Built By Our AI Team

These scaffolding and analysis tools come from our own AI development services team, covering AI agents, automation and generative AI, applied inside the extension project itself rather than sold as a separate product.

Why Raulji Technologies

We Extend Magento Without Ever Touching Its Core

Extension problems are predictable: core edits, class rewrites, no tests and no docs. Our approach exists to remove exactly those failure modes so your modules keep working upgrade after upgrade.

No Core Edits

Every change goes through plugins, preferences and observers, so Magento core and vendor code stay untouched and patchable.

Coding Standards

Modules follow the Magento coding standard and pass PHPCS, so they read cleanly and clear Marketplace review.

Conflict Aware

We map how a new module interacts with the ones you already run, so we prevent collisions instead of discovering them live.

Tested

Unit and integration tests around the module’s logic mean upgrades can be verified rather than crossed fingers.

Upgrade Ready

Modules are structured and version-constrained so the next Magento upgrade does not turn into a rescue project.

Documented

Configuration, dependencies and behaviour are written down and handed over, not kept in one developer’s head.

You Own It

Custom and private modules are delivered with source and version control, so the code is yours to keep and extend.

Long-Term Support

After delivery we keep modules compatible through ongoing Magento support as your store and Magento both evolve.

Industries

Extensions That Solve Real Industry Problems

The most useful custom modules are the ones built around how a specific industry actually operates. These are the sectors where bespoke extensions earn their keep.

B2B and wholesale Magento extension development

B2B / Wholesale

B2B & Wholesale

Challenge: tiered pricing, quote approvals and requisition rules that no off-the-shelf module gets exactly right.
Solution: custom modules for negotiated pricing, credit terms and company-account logic.
Outcome: buyers self-serve at their own prices without a marketplace extension fighting your workflow.

See B2B Solutions

Fashion

Fashion & Apparel

Challenge: size charts, fit finders and back-in-stock alerts that stock extensions handle only halfway.
Solution: custom or extended modules for merchandising, swatches and notifications tuned to your catalog.
Outcome: shoppers reach the right variant faster and fewer of them abandon over uncertainty.

See Fashion Solutions

Ecommerce

Ecommerce & Retail

Challenge: promotions, loyalty and shipping rules where three separate extensions overlap and conflict.
Solution: we consolidate the logic into fewer, cleaner modules and resolve the collisions at source.
Outcome: a lighter admin, fewer moving parts, and promotions that behave as intended.

Frequently Asked Questions

Common Questions About Magento Extensions

What kinds of Magento extensions do you build?

We build custom Magento 2 and Adobe Commerce extensions of all kinds: bespoke feature modules for a specific business need, integrations packaged as extensions, admin tools and reports, storefront enhancements, and extensions intended for the Adobe Commerce Marketplace. If a feature does not exist or an off-the-shelf module does not fit, we build one that does.

Can you customise an existing third-party extension?

Yes. We extend and customise third-party extensions cleanly using Magento plugins, preferences and event observers, rather than editing the vendor code directly, so your changes survive the extension being updated.

Two of my extensions conflict. Can you fix that?

Yes. Extension conflicts are one of the most common issues we resolve. We trace the clash, whether it is a rewrite collision, a plugin ordering problem or a shared dependency, and resolve it so both features work together.

Do you follow Magento coding standards for extensions?

Yes. Our extensions follow the Magento coding standard and PSR conventions, use dependency injection and the module structure Magento expects, and avoid core edits, so they are maintainable and upgrade-safe.

Will your extensions survive a Magento upgrade?

That is the goal. We build extensions the way Magento intends, so they are compatible across versions where possible, and we can update them for a new major version as part of an upgrade project.

Can you build an extension for the Adobe Commerce Marketplace?

Yes. We can build extensions to Marketplace technical and quality standards, including the coding, security and documentation requirements, so they are ready for submission and sale.

Do you provide the source code?

For bespoke extensions built for you, yes, you own the code. We hand over clean, documented source so your team or any other developer can maintain it.

Can you make an existing extension faster?

Often, yes. If an extension is slowing your store, we can profile it, optimise its queries and logic, or rework how it loads, and where it is beyond help we can advise on a better replacement.

Do you support the extension after it is built?

Yes. We offer ongoing support and maintenance for the extensions we build, including compatibility updates, bug fixes and enhancements as your needs change.

How is a custom extension different from customization?

A custom extension is packaged, reusable functionality installed as a module, ideal when you want a clean, portable, upgrade-safe feature. Broader customization tailors the store itself. We often use both together and will recommend the right approach for your case.

How long does a custom extension take?

It depends on the complexity of the feature. A focused extension can be a matter of days; a complex one with admin UI, integrations and Marketplace-grade quality takes longer. We scope and quote it up front after understanding the requirement.

Can you install and configure extensions we have bought?

Yes. We install, configure and test purchased extensions on staging first, resolve any conflicts with your existing modules, and deploy them safely so nothing breaks on your live store.
