Custom Magento work at enterprise scale
When a standard Magento setup stops fitting
Extensions cover the common cases. The moment your pricing model or fulfillment flow works differently, your store needs code written for it.
Extension conflicts pile up
Stacked third-party modules patch symptoms and conflict with each other. A custom module built for your exact flow replaces them with code you control.
Integrations keep breaking
Stock counts drift and orders stall when ERP connections are patched together. Custom integration work ties Magento to your back office reliably.
The build stalled elsewhere
The current partner keeps missing deadlines, and confidence is gone. We take over Magento projects mid-build and carry them to launch.
Why complex builds come to scandiweb
The most certified Magento team
894+ Adobe Commerce certifications, more than any other agency, and 600+ in-house experts cover every discipline during a custom build.
We build our own Magento tools
ScandiPWA, ReadyMage, and Create Magento App were built here. When your project needs something the ecosystem lacks, we write it ourselves.
Requirements mapped before code
Our discovery process is based on MIT System Engineering practice. Requirements and acceptance criteria are mapped before development starts, so the estimate you sign holds.
Your code, no lock-in
You pay once for the build, and every line of code is yours. Nothing in the agreement stops you from changing vendors later.
Proactive support and growth
Ongoing monitoring and issue fixing is a given. We go further by identifying and prioritizing revenue opportunities to keep your Magento store growing.
Innovators in Magento
We know Magento inside out and build tools like Satoshi for Hyvä, Hyvä Swift UX design system, and ReadyMage hosting to improve speed, stability, and development workflows.

How a custom Magento build runs at scandiweb
Every build follows a discovery and delivery methodology designed for complex systems. You see progress in weekly demos, and the roadmap covers every stream from design to data.
Discovery and estimate
We analyze your current operations and define what gets built: platform, custom features, integrations, and data layer. The estimate produced in discovery is the one written into your agreement.
MVP on the Accelerator
Our Accelerator Program delivers a production-ready Magento 2 store in days, so you can trade early while bespoke features are still being built.
Build sprints with demos
Design, frontend, backend, and integration streams run in parallel against a shared roadmap. Every week or two you join a demo and receive a written progress report.
UAT and controlled Go-Live
After internal testing, the site runs end-to-end user acceptance tests and a pre-live simulation. DNS switches only after the full order flow passes.
Post-launch growth
The first weeks after Go-Live are monitored daily by our Magento support team. Most clients then keep a growth team of 2 to 4 people who run improvements across the store and its marketing.

Questions merchants ask before a custom build
What is custom Magento development?
Custom Magento development means building functionality that does not exist in Magento's core or extension marketplace: bespoke pricing logic, B2B workflows, ERP integrations, or a fully custom storefront. It is coded to Magento standards so upgrades stay safe, and it is the right path when off-the-shelf modules would need heavy modification to fit.
Adobe Commerce or Magento Open Source?
We build on both. Adobe Commerce earns its license fee when you use its native B2B suite, page builder, staging, and support SLAs. Magento Open Source fits leaner setups where those come from the ecosystem instead. We model the total cost of both during discovery so you can compare real numbers.
What does a custom Magento build cost?
The platform setup is the small part of the budget: ReadyMage gives you a production instance with a React storefront in one click. Cost scales with what is unique to you, mostly custom features and integrations. Discovery produces a scoped estimate before you commit, and our globally hired team keeps hourly rates competitive.
Can you migrate us from another platform?
Yes. We have moved stores to Magento from Shopify, SAP Commerce, Demandware, Sylius, and custom-built platforms, with every order and customer account preserved. The move follows its own runbook, detailed on our Magento migration page, and SEO work runs in parallel so rankings survive the switch.
Do you build custom modules or use extensions?
Both, chosen case by case. A well-maintained extension is cheaper when it covers the requirement cleanly. When it covers 80% and the missing 20% is your business model, a custom module usually costs less over time than a modified extension, because upgrades stop breaking. Discovery makes that call requirement by requirement, with the trade-offs priced.
How long does a custom Magento build take?
A full build with design, bespoke features, integrations, and SEO setup usually runs 4 to 6 months. We discourage anything planned to run longer and phase the scope instead. The fastest launch we have delivered took two weeks, for a client with an urgent exhibition deadline, using our Accelerator base.
Will we own the code you write?
Yes. The agreement states a one-time project fee with no lock-in and no code rent. The code sits in your repository, documented so any Magento team can maintain it. Third-party license fees stay payable to their vendors, and we can review those contracts with you.
Can you take over a Magento project that has stalled?
Yes, take-overs are a standing service. The first step is a code and delivery-process audit that identifies what is blocking the build and what is salvageable. Most rescues then reach Go-Live without a restart, with progress visible in weekly demos.
