The cost of the wrong extension
Is Your Extension Holding You Back?
If any of these feel familiar, a custom extension isn't a luxury, it's the fix. Every one of these problems is solvable with the right approach and the right team.
06 failure points we design out of every build
- 01
A marketplace extension that almost fits your catalog
Most Magento extensions are written for the average catalog. The moment your attributes, pricing rules or B2B workflow get specific, you're paying for an extension and still building workarounds around what it doesn't cover.
- 02
Extension conflicts breaking the storefront
Magento's modular architecture means a poorly scoped extension can clash with another, or with core code, in ways that only surface after a deploy. Properly scoped code avoids that entirely.
- 03
A module nobody's patched in years
Magento stores handle serious transaction volume, which makes them a frequent target. An abandoned or carelessly built extension sitting in your codebase is a liability you may not even know about.
- 04
No real line to your ERP or PIM
Off-the-shelf extensions don't know your ERP, PIM or fulfillment systems exist. A purpose-built extension connects Magento to the rest of your stack through proper APIs.
- 05
B2B and complex pricing logic that doesn't map
Tiered pricing, customer groups, quotes and negotiated terms rarely fit cleanly into a generic extension. Built-for-you logic follows your actual B2B workflow instead.
- 06
Functionality your catalog depends on, but doesn't own
When checkout, pricing or catalog logic leans on a third-party extension you don't control, a licensing change or a deprecated module can break something critical overnight.

What we build
Our Magento extension development services
From a focused pricing module to a multi-module B2B extension with ERP integration, every project starts from a blank file.
Custom Pricing & Promotion Rules
Tiered pricing, customer-group pricing, negotiated quotes and complex promotions built as proper Magento pricing modules, never theme-level hacks.
B2B Module Development
Company accounts, quote workflows, requisition lists and approval chains built around Magento's B2B module, or as custom extensions where the built-in features fall short.
Custom Product Types & Attributes
Configurable, bundled or custom product types and EAV attributes registered cleanly through Magento's data model, giving merchandisers the structure they actually need.
Checkout & Payment Customization
Custom checkout steps, payment integrations and validation built on Magento's checkout and payment APIs, keeping the flow fast and PCI-aware.
ERP, PIM & Third-Party Integration
Extensions that connect Magento to your ERP, PIM, 3PL or CRM through REST, GraphQL and message queues, so catalog and order data sync without manual exports.
Admin UI & Reporting Modules
Custom admin grids, forms and reports built with Magento's UI Components framework, giving your team the exact read on orders and inventory they need.
Magento Marketplace Submission
Extensions prepared against technical and security review guidelines and submitted to the Magento Marketplace, so approval isn't a scramble.
Security Hardening
Input validation, ACL permissions, CSRF protection and secure coding practices built in before any extension touches checkout or customer data.
Performance Optimization
Indexers, caching and query tuning handled correctly, so new functionality never comes at the cost of page load or reindex time.
Extension Audit & Refactor
Existing Magento extensions reviewed for security gaps, deprecated APIs and slow queries, then refactored to current Magento 2 standards.
Maintenance & Support
Ongoing updates for Magento platform releases, security patches and a helpdesk that keeps your storefront and checkout running while you run the business.

Why choose us
Magento development done the right way
Anyone can write a module that hooks into Magento. We engineer extensions that are secure, lean, compatible with the next platform release and fully owned by you, then stay around to maintain them.
Start your project-
Built to Magento's module architecture
Every extension follows Magento 2's dependency injection, plugin and observer patterns properly, so it behaves predictably and avoids conflicts with other modules.
-
Security as a default, not an afterthought
ACL permissions, CSRF protection and input validation sit next to checkout and customer data from day one, not bolted on after a review flags a problem.
-
Lean by design
Indexers and caching are handled correctly from the start. Your extension adds functionality without slowing page load or reindexing.
-
Wired into your stack
We connect to your ERP, PIM, 3PL and APIs so Magento runs as part of your operation, not as an island sitting apart from the rest of the business.
-
Built for real B2B complexity
Tiered pricing, customer groups and quote workflows are built around how your business actually sells, not a generic catalog assumption.
-
You own the code
Full IP assignment on every contract. The extension belongs to you outright, with no recurring licence fee on your own functionality.
-
Real overlap with your working day
Three to four hours of daily overlap with US, UK and Canada time zones, so demos and decisions happen while you're actually at your desk.
-
Built to age well
We keep extensions current as Magento releases new platform versions, so a major upgrade never breaks checkout overnight.
How we work
Our Magento extension development process
Eight clear stages, each with a visible output you can review and approve. No black box between kickoff and launch.
- 01
Discovery
We map your catalog structure, pricing logic and integration points before a line of code gets written.
- 02
Architecture
Module structure, data model, API approach and admin UI plan agreed and documented before development starts.
- 03
UI Design
Admin grids, storefront changes and checkout steps designed and signed off before we touch code.
- 04
Development
Clean, documented PHP built to Magento 2 coding standards, with a demo at every milestone.
- 05
QA & Testing
Cross-version compatibility, indexer, checkout and edge-case testing before anything ships.
- 06
Launch
Deployed to your live environment or submitted to the Magento Marketplace with review guidelines already met.
- 07
Review Support
Any reviewer feedback handled quickly, so your listing clears without unnecessary back-and-forth.
- 08
Support
Ongoing updates and compatibility checks with every Magento platform release.

Client words
Trusted by stores that depend on their Magento extensions
Our customer-group pricing and quote workflow were too specific for any Marketplace extension to handle. The custom module they built now runs our entire B2B sales process without a manual override.
Three extensions were conflicting after a Magento upgrade. They rebuilt the functionality as one clean custom module, and our next upgrade went through without a single regression.
Syncing ERP inventory into Magento used to mean a nightly manual export. The integration they built keeps stock levels accurate in real time across both systems.
Questions, answered
Magento extension development FAQs
How much does a custom Magento extension cost?
The cost depends on the extension's functionality, integrations and complexity. A focused module is simpler, while multi-module B2B extensions with ERP integrations require more development. Every project is scoped and quoted individually.
How long does a Magento extension take to build?
A focused, single-feature module typically takes 4 to 8 weeks. A multi-module B2B extension with admin interfaces and ERP integration usually runs 10 to 18 weeks. You see a working build early, with a demo every sprint.
Do you build for Magento Open Source and Adobe Commerce?
Yes. We build for both Magento Open Source and Adobe Commerce, accounting for the additional B2B and enterprise features available on Commerce where the project calls for it.
Can you build custom pricing or B2B workflows?
Yes. Tiered pricing, customer-group pricing, negotiated quotes and requisition list workflows are among the most common reasons clients come to us for a custom Magento extension.
Can the extension connect to our ERP or PIM?
Yes. ERP, PIM and third-party integration through REST, GraphQL and message queues is a core part of our Magento practice, so catalog and order data sync automatically instead of relying on manual exports.
Will the extension slow down our storefront or reindexing?
We handle indexers and caching correctly as part of every build, so functionality gets added without dragging down page load or reindex time. Performance gets tested before launch, not assumed afterward.
Can you fix conflicts between existing extensions?
Yes. We audit the conflicting modules first, identify the actual cause, then either resolve the conflict directly or consolidate the functionality into one clean custom module that avoids the issue going forward.
Will the extension stay compatible with Magento platform updates?
We code to current Magento 2 APIs and avoid deprecated patterns, which cuts compatibility risk substantially. Our maintenance plans also cover testing and updates with every Magento platform release.
Do you handle Magento Marketplace submission?
Yes. We prepare the extension against Magento Marketplace technical and security review guidelines and manage submission, handling any reviewer feedback until the listing is approved.
Can you audit or fix an extension we already have?
Yes. We audit existing extensions for security issues, deprecated APIs and performance problems, then refactor to current standards. This is often faster and cheaper than a full rebuild.
Do you provide maintenance after the extension launches?
Yes. Our maintenance plans cover Magento version compatibility, security patches, bug fixes and a monthly bucket of improvement hours, with most issues resolved overnight your time.
What happens after the extension launches?
Every project includes a handover, documentation and a warranty window for fixes. Most clients move onto a maintenance plan so the extension stays current as Magento evolves. We're still around for version two, not just while the invoice is open.
