Why UK Businesses Choose Mtoag for Magento Development
Three things that separate us from every other agency in the UK.
Fixed-Price. No Surprises.
Before writing a line of code, we produce a Technical Specification — a fixed-price, fixed-scope document listing every feature, integration, and delivery milestone. You sign it. We build it. The price you sign is the price you pay.
150+ In-House Engineers. No Subcontractors.
100% of Mtoag's engineering work is done by direct employees — never freelancers, never agencies, never offshore subcontractors. Your senior developer has worked at Mtoag for an average of 4+ years.
Full IP Ownership from Day One.
Your source code, design files, and all intellectual property transfer to you on final payment. We sign an NDA before any technical discussion. No vendor lock-in.
The Tech Stack That Powers Our Solutions
Sixteen years of production experience across mobile, web, enterprise, open-source, and search — every technology below is one we ship for UK clients, not just list on a page.
From native performance to cross-platform speed, we build mobile experiences that feel first-class on every device.
Modern, fast, accessible websites and web apps built on frameworks that scale with your business, not against it.
Enterprise-grade architecture built for security, compliance, and systems that need to talk to each other reliably.
Proven open-source platforms customised and hardened for real commercial traffic — not a stock install.
Technical SEO built into the codebase from day one — because rankings are an engineering outcome, not a marketing add-on.
All versions current as of July 2026. We track and adopt major releases within 90 days.
Magento Development Case Studies
All projects live in production since launch.
Our Magento Development Process
The same six-step process on every project. No improvising. No scope creep. No surprises.
Discovery and Technical Scoping
A structured 45-minute discovery call followed by a written Technical Specification defining every feature, integration, performance target, and accessibility requirement. You review and sign it before we charge a penny.
Architecture and Prototype
Technical architecture decisions and a working prototype covering the core user flows, so decisions are validated before full development begins.
Agile Development and Build
Two-week sprints with a live staging environment accessible 24/7. Weekly video demos and Slack access to your project manager. All code reviewed by a senior engineer before it merges.
Quality Assurance Testing
Automated unit and integration testing, manual regression testing, and a full accessibility and performance audit before anything ships to production.
Launch and Monitoring
Zero-downtime deployment with instant rollback capability. Performance monitored for 30 days post-launch, with fixes included in the launch fee.
Support and Ongoing Development
Post-launch SLA options from 8-hour response to 24/7 monitoring. Monthly security patches, dependency updates, and performance reports. Ongoing feature development available on sprint retainer.
All timelines are fixed in the Technical Specification.

Magento Development Questions Answered
10 direct answers. No sales language.
Magento projects are quoted as a fixed price after scoping, typically £25,000–£80,000+ depending on catalogue size, B2B complexity, and integration count. Mtoag provides a fixed quote from a written Technical Specification, not an hourly estimate.
Yes, for complex, high-SKU, or B2B commerce. Adobe Commerce (Magento) remains the strongest open-source platform for negotiated pricing, multi-store, and large catalogue requirements that Shopify and WooCommerce handle less natively.
Yes. Mtoag’s migration process maps product, customer, and order data from Magento 1 to Magento 2 with a full SEO redirect strategy, typically completing in 8–12 weeks depending on catalogue size and custom extension count.
Yes. Magento B2B quoting, negotiated customer-group pricing, and company account hierarchies are a core Mtoag Magento specialism — not a bolt-on module.
Mtoag tunes full-page caching, Elasticsearch indexing, image optimisation, and database indexing as standard, typically achieving sub-2-second load times even on large catalogues.
A fixed-price quote includes scoping, development, QA testing, deployment, and a 30-day post-launch support window. Standard payment and shipping integrations are included, not billed as separate line items.
A standard Magento storefront takes 8–12 weeks from kick-off to launch. Complex B2B or multi-store platforms take 12–20 weeks. Every project receives a fixed timeline in the Technical Specification before development begins.
Yes, 100%. All theme code, custom modules, and configuration created for your project belong to you from day one, written into every Mtoag contract as standard.
For most new Magento projects, yes. Hyvä delivers significantly faster frontend performance than the default Luma theme with a simpler codebase. Mtoag recommends Hyvä as the default for new builds.
Every project includes a 30-day post-launch support window covering bug fixes at no extra cost. Ongoing security patching, extension updates, and feature development are available on a monthly retainer after that window closes.
