We design and build Magento 2 extensions from scratch, following
Magento's module architecture and coding standards. No fragile
overrides, no indexer slowdowns, just clean functionality that
belongs to you and survives every platform upgrade.
Is a Marketplace extension creating more problems than it solves?
If any of these feel familiar, a custom extension is not a luxury, it
is the fix. Every one of these problems is solvable with the right
approach.
Marketplace extensions that almost fit your catalog
Most Magento extensions are built for the average catalog. When your product attributes, pricing rules or B2B workflow need something specific, you end up paying for an extension and still building workarounds around the gaps.
Extension conflicts breaking the storefront
Magento's modular architecture means a poorly written extension can conflict with another, or with core code, in ways that only surface after a deployment. Lean, properly scoped code avoids that entirely.
Security vulnerabilities in unmaintained modules
Magento stores handle high transaction volumes, making them a frequent target. An abandoned or carelessly built extension sitting in your codebase is a liability you may not even know about.
No real connection to your ERP or PIM
Off-the-shelf extensions do not know about your ERP, PIM or fulfillment systems. A custom extension connects Magento to the rest of your business stack through proper APIs.
B2B and complex pricing logic that does not fit
Tiered pricing, customer groups, quotes and negotiated pricing rarely map cleanly onto generic extensions. A custom module is built around your actual B2B workflow.
No ownership of functionality your catalog depends on
When checkout, pricing or catalog logic depends on a third-party extension you do not own, a licensing change or a deprecated module can break critical functionality 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 Magento 2 Extension Development
Custom Magento 2 modules built from scratch around your exact requirements, following Magento's module architecture and coding standards.
Custom Pricing & Promotion Rules
Tiered pricing, customer-group pricing, negotiated quotes and complex promotion logic built as proper Magento pricing modules, not 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 method 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 automatically.
Admin UI & Reporting Modules
Custom admin grids, forms and reports built with Magento's UI Components framework, giving your team the exact view of orders and inventory they need.
Magento Marketplace Submission
Extensions prepared and submitted to the Magento Marketplace, meeting technical and security review guidelines so listing approval is not a scramble.
Security Hardening
Input validation, ACL permissions, CSRF protection and secure coding practices built into every extension before it touches checkout or customer data.
Performance Optimization
Indexers, caching and query optimization handled correctly so your extension adds functionality without dragging down page load or catalog reindex time.
Extension Audit & Refactor
Existing Magento extensions audited for security issues, deprecated APIs and performance problems, then refactored to current Magento 2 standards.
Maintenance & Support
Ongoing updates for Magento platform releases, security patches and a fast helpdesk that keeps your storefront and checkout running.

Why choose us
Magento extension development done the right way
Anyone can write a module that technically runs. We engineer
extensions that are secure, lean, compatible with the next platform
upgrade and fully owned by you, then stay around to maintain them.
Every extension follows Magento 2's dependency injection, plugin and observer patterns properly, so it behaves predictably and avoids conflicts with other modules.
Security by default
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. Your extension adds functionality without dragging down page load or making catalog reindexing slower.
Connected to your stack
We integrate with your ERP, PIM, 3PL and APIs so Magento becomes part of your operation instead of 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.
Overlap with your hours
Three to four hours of daily overlap with US, UK and Canada time zones, so demos and decisions happen in your working day.
Long-term compatibility
We keep your extension updated as Magento releases new platform versions, so a major upgrade does not break 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 the catalog structure, pricing logic and integration points the extension needs to cover.
02
Architecture
Module structure, data model, API approach and admin UI plan agreed before a line of code is written.
03
UI Design
Admin grids, storefront changes and checkout steps designed and reviewed before development starts.
04
Development
Clean, documented PHP built to Magento 2 coding standards with demos at every milestone.
05
QA & Testing
Cross-version compatibility, indexer, checkout and edge-case testing before deployment or submission.
06
Launch
Deployed to your environment or submitted to the Magento Marketplace with review guidelines met.
07
Review Support
Any reviewer feedback addressed quickly so your listing is approved without unnecessary back-and-forth.
08
Support
Ongoing updates and compatibility checks with each Magento platform release.
What is included
A Marketplace listing is not the same asset
The difference between an off-the-shelf extension and a custom-built
one is everything that happens under the surface. Here is what comes
standard with every extension we deliver.

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 runs our entire B2B sales process now without a manual override.
ED Ecommerce DirectorIndustrial supplies distributor, United States
We had three extensions conflicting with each other after a Magento upgrade. They rebuilt the functionality as one clean custom module and our next upgrade went through without a single regression.
Ho Head of ITMulti-brand fashion retailer, United Kingdom
Syncing our ERP inventory into Magento used to need a nightly manual export. The integration extension 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?
Most custom extension projects land between $6,000 and $60,000 depending on complexity and the number of integrations. A focused pricing or admin module sits at the lower end; a multi-module B2B extension with ERP integration sits higher. Every quote is itemized before work begins.
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 and a demo every sprint.
Do you build for Magento Open Source and Adobe Commerce?
Yes. We build extensions 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 some of the most common reasons clients commission 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 is added without dragging down page load or making catalog reindexing slower. Performance is tested before launch, not assumed.
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 significantly reduces compatibility risk. Our maintenance plans also include testing and updates with each Magento platform release.
Do you handle Magento Marketplace submission?
Yes. We prepare the extension to meet Magento Marketplace technical and security review guidelines and handle the submission process, addressing 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 are still available for version two, not just while the invoice is open.
