Magento Design and Development Built for Ecommerce That Has Outgrown Everything Else

TransFunnel builds custom Magento ecommerce solutions for B2B and B2C businesses.  We start with commercial requirements. The build follows from those.

Clients Who Trust Us

Talk to a Magento Developer

Most Magento Projects Start When Something Has Already Gone Wrong Growth changes what a Magento store needs to do. What worked at launch stops working when the catalogue triples; the team grows, or a campaign drives the usual traffic ten times. These are the six situations we see most often.

Image 1 01

The store launched well, but every major campaign now grinds it to a halt

Magento performance issues usually stem from architecture. Over time, extension overload, inefficient queries, and poor caching combine to hurt conversions. We address performance during design and development—through better caching, cleaner code, and leaner builds.

The store works, but the team fights the backend every day

Magento’s flexibility can lead to setups that are difficult for teams to use. Everyday tasks like managing products or promotions shouldn’t require developer support. We configure the admin around how your team actually works.

03

Too many extensions, none of them quite doing what was needed

Each extension adds complexity. Too many create conflicts and slow the store down. We audit what’s in place, remove unnecessary dependencies, and build custom functionality only where needed.

04

The storefront looks fine, but visitors leave before they buy

Good Magento design goes beyond visuals. It’s about helping users find products, making decisions, and completing checkouts easily. Most stores fall short in at least one of these areas.

The integrations were added as an afterthought and operations are fragmented

ERP, CRM, PIM, and other systems are often added over time without a plan, leading to fragile setups. We define integration architecture early, when changes are easier and more cost-effective.

06

The migration happened. The SEO recovery has not.

Magento migrations are also SEO events. Missed redirects, lost metadata, and unplanned structure changes can impact rankings. We treat SEO continuity as a core part of the migration process.

What Our Magento Design and Development Services Cover

Custom Magento website development services span a lot of ground. Here is what we do and what each part actually involves.

Magento Strategy and Discovery

We spend the first part of every engagement asking the questions that shape the build: what does the business sell and how, who is buying and how they browse, what systems does the store need to connect to, and what is the current setup getting wrong. The answers to those questions determine the architecture. Skipping them produces a technically sound store that does not actually fit the business.

Magento Storefront Design and Development

Magento web design that balances brands with commerce. We design how buyers navigate: category pages that support product discovery, product detail pages that give buyers what they need to decide, and checkout flows that remove friction rather than adding it. Built in Figma as a component system that development can build from and the team can use for future pages.

Magento Catalogue, Admin, and Workflow Configuration

Magento is capable of handling complex catalogue structures, pricing rules, promotions, and multi-store setups. The configuration that makes it work for a specific business is the part that takes judgment, not just technical execution. We structure the backend around how the team actually manages the store, so the platform serves the business rather than requiring the business to serve the platform.

Custom Magento Ecommerce Development

Some commercial requirements cannot be met with standard Magento configuration or available extensions. Custom checkout flows, account-based pricing, B2B buying workflows, regional catalogue structures, and loyalty programme integrations are examples. We build custom functionality when the commercial requirement is clear and the available alternatives fall short.

Magento Extension and Custom Module Development

Magento software development should keep the platform lean, not add to it. We audit existing extensions with a view to reducing the overall dependency footprint. When a module is needed, we build it to a standard that can be maintained by any competent Magento developer, with documentation that explains the decision as well as the code.

Magento Performance Optimization

Slow Magento stores lose revenue in ways that show up directly in analytics but are slow to attribute correctly. We address the real causes: frontend efficiency, caching configuration, database query optimization, asset delivery, and code that has accumulated over time. Performance is part of every build we do, and a standalone engagement when an existing store needs it.

Magento Migration and SEO Continuity

Moving to Magento from another platform, or between Magento versions, needs structured planning. Catalogue mapping, URL redirects, metadata migration, data integrity validation, and analytics continuity are all part of how we manage migrations. The goal is a move that supports growth rather than one that creates a six-month recovery period.

Magento Security and Ongoing Support

Magento stores need consistent maintenance. Updates, patching, security reviews, environment checks, and performance monitoring are not optional. We offer structured support that keeps the store stable and commercially ready, with enough visibility into the setup that issues are caught before they reach customers.

Magento Integrations Across the Commerce Stack

ERP, CRM, PIM, payment gateways, shipping, analytics, and marketing automation. These integrations need to be designed into the Magento development solutions from the start, tested against real operational scenarios, and documented clearly enough that the team knows what is connected and what to do when something changes.

Magento Projects Start from Different Pressures

How We Run a Magento Engagement

We follow the same sequence on every project. The depth of each phase scales with what the project requires. What does not change is the order, because skipping phases is how avoidable problems get created.

Step 01

Discovery

Business model, catalogue structure, target buyers, existing platform audit, operational workflows, integration requirements, and a clear picture of where the current setup falls short. We also talk to the team who manage the store. They usually know more about what needs to change than the brief captures.

Step 02

Information Architecture and Wireframes

Category and product page hierarchy, navigation logic, search and filtering behaviour, checkout flow, and account management for B2B. The commerce architecture is agreed before visual design starts. Changes at this stage are conversations. Changes at visual design stage cost a week.

Step 03

Visual Design

High-fidelity design in Figma, built as a component system that development builds directly. Two structured rounds of feedback with defined approval gates. The system covers every page template, state, and interaction needed to build the store without guesswork.

Step 04

Development

Custom themes build on the agreed component system. Extension selection kept intentional. Performance, accessibility, and SEO requirements defined in the build spec and tested throughout the development process. Backend configuration includes catalogue structure, pricing rules, promotions, and admin workflows.

Step 05

Integration and Testing

ERP, CRM, PIM, payment gateways, shipping, and marketing platform integrations connected and tested against real operational scenarios. Cross-device and cross-browser testing. Performance benchmarked against agreed targets. Security baseline reviewed before anything goes to staging.

Step 01

Launch and Handover

Phased launch with a defined go-live checklist. SEO migration is validated. Analytics and attribution confirmed working. Team trained on the admin workflows they will use daily. Documentation covers the theme, extensions, integrations, and maintenance procedures. The store is yours to run from day one.

Frequently Asked Questions

How much does a Magento design and development project cost?

We do not publish pricing because the scope varies too much for a number to mean anything without context. A focused B2C storefront is a very different engagement from a B2B multi-region Magento build with custom pricing logic and ERP integration. We provide fixed-price proposals after discovery, once the requirements are properly defined. If you have a budget, tell us on the first call. We will scope it or tell you clearly if it is not realistic. 

How long does a Magento website take to build?

A focused build can take a few months from brief to launch. A larger replatform, B2B implementation, or complex integration project takes longer. The timeline we give you after discovery will be specific and fixed. The timeline you find on most agency websites is an estimate that survives right up until the requirements are actually understood.

Is Magento the right platform for our business?

Probably, if you have outgrown something simpler, have a complex catalogue or pricing model, need deeper integration with business systems, or are building a B2B buying experience. Probably not, if your catalogue is small, your requirements are straightforward, or you want the marketing team to manage the site without technical help. We assess platform fit in discovery rather than assuming Magento is always the answer.

What does custom Magento development include?

Building features, workflows, and storefront experiences around your specific commercial model rather than relying on what Magento provides by default or what extensions offer. Custom checkout flows, B2B account structures, complex pricing logic, regional catalogue management, and bespoke integrations are the most common examples.

Can you take over an existing Magento store?

Yes, and it is one of the most common starting points for a Magento project. We audit the current build, document what is in place, identify what is worth keeping and what is creating problems, and either stabilize and improve or recommend a phased rebuild depending on what the audit finds.

How do you handle Magento security and ongoing support?

Magento stores that are not actively maintained get vulnerable. Updates, patching, extension reviews, security audits, and infrastructure monitoring are not optional. We offer structured maintenance that keeps the store stable and reduces the risk of issues that reach customers or disrupt operations.

Can Magento connect to our ERP, CRM, PIM, and marketing platforms?

Yes. Magento integrates with most major business systems. The important thing is planning the integrations before development rather than adding them after. Post-launch integrations tend to be more expensive, less reliable, and harder to test. We treat the integration architecture as a first-order design decision, not a delivery detail.

Can you migrate us to Magento from another platform?

Yes. Catalogue mapping, URL redirects, metadata migration, data integrity validation, analytics continuity, and launch planning are all part of how we handle Magento migrations. A migration is also an SEO event, and we treat it as one from the start rather than discovering that fact three months after launch.

What happens after the Magento store launches?

We offer structured ongoing support: updates, performance monitoring, issue resolution, and planned enhancements. We train the team before handover and document the setup so that day-to-day management is clear and not entirely dependent on us. Ongoing support is available as a retainer or on a project basis, depending on what the business needs.

Why choose TransFunnel for Magento design and development?

We are not a Magento-only studio. We are a consultancy that builds on Magento when it is the right platform for commercial requirements. That means the build is designed around the business model, the team who will run the store, and the systems it needs to connect to. We also think about what happens after launch, which is where most ecommerce partnerships either hold up or fall apart.
