eCommerce engineering

eCommerce engineering for platforms that must work beyond the storefront.

We help retailers, wholesalers and B2B organisations build and improve eCommerce platforms, integrations and operational workflows. Magento Open Source is our deepest commerce specialism, while our wider engineering capability supports broader platforms and custom commerce requirements where they are a better fit.

The bigger picture

Start with the business and technical reality

A serious eCommerce operation is a connected system rather than a collection of product pages. Catalogue data may originate in a PIM or ERP, stock may be controlled by a WMS, orders can flow into accounting and fulfilment systems, and customers expect accurate availability, payments, delivery choices, refunds and account information in real time.

That means commercial problems often have technical causes outside the storefront. Overselling can be an inventory integration problem. Slow checkout can be caused by third-party calls. Poor merchandising can originate in product-data structure. Support teams can be overwhelmed because fulfilment status is not returned cleanly to the website. We investigate the whole order and data lifecycle rather than treating each symptom in isolation.

We can deliver new builds, targeted improvements, replatforming, integrations and ongoing engineering. For established platforms, preserving what already works can be just as important as changing what does not.

Typical situations

When clients bring us in

  • The current commerce platform has become difficult to extend
  • ERP or WMS processes create manual work around orders and stock
  • Site performance is affecting conversion or operational stability
  • A B2B business needs account-specific pricing, approvals or catalogues
  • Multiple marketplaces or suppliers need controlled data synchronisation
  • An existing agency lacks the technical depth for complex Magento or integration work
The objective

What good delivery should leave behind

A successful engagement should improve more than the immediate feature or incident. It should make the system easier to understand, safer to change and more visible to the people responsible for operating it.

  • Clear technical ownership and responsibilities
  • Maintainable code and configuration
  • Visible failures rather than silent data loss
  • Controlled release and recovery paths
  • Documentation for future developers and operators
  • A sensible next-step roadmap rather than permanent firefighting
What the work covers

Technical depth across the parts that matter

The exact scope depends on the existing environment and commercial priorities. We focus on the areas that materially affect reliability, maintainability and delivery rather than adding process for its own sake.

Commerce platform

Storefront, catalogue, checkout, accounts, promotions, admin workflows and platform configuration.

Product & inventory data

Define where product information, pricing and sellable stock originate and how they synchronise.

Orders & fulfilment

Control order export, allocation, shipment updates, cancellations, refunds and exceptions.

Payments & delivery

Integrate gateways, fraud tools, carriers, collection, shipping rules and tracking.

Performance & resilience

Optimise application, cache, search, database and infrastructure around real traffic and catalogue size.

Ongoing delivery

Support releases, maintenance, monitoring, roadmap work and operational improvements.

Problems we look for

Common failure patterns that create unnecessary cost

Many technical problems are recurring patterns rather than isolated defects. Identifying them early helps avoid repeatedly paying to treat the visible symptom.

  • Stock values disagreeing between systems
  • Order failures hidden in queues or scheduled jobs
  • Promotions and pricing logic becoming difficult to test
  • Checkout depending on slow or fragile third-party services
  • Large catalogues creating indexing and search problems
  • Manual reconciliation because integrations lack visibility
How we work

A controlled route from uncertainty to production

We prefer visible, reviewable delivery. The exact sequence changes with the project, but the principle is to reduce uncertainty early and keep each production change understandable.

01Map commercial and operational workflows
02Identify systems of record
03Prioritise customer and operational risks
04Build or improve in controlled workstreams
05Test realistic order and exception scenarios
06Monitor and optimise after release
Engineering judgement

Technology is part of the answer, not the starting question

Magento Open Source is particularly strong where the business needs extensibility, complex catalogues and deep integrations, but it is not automatically the right platform for every project. We can help compare the cost of improving the current platform against replatforming, custom development or a simpler commerce stack.

Where specialist capability comes from our wider engineering team, we are transparent about the proposed delivery model and match the person or team to the actual requirement rather than presenting a long list of technologies as if every project needs all of them.

In practice

Follow the order, not just the page

A practical way to assess an eCommerce estate is to follow one order from product creation through payment, fulfilment, shipment, refund and reporting. Every place where staff copy data, check another system, wait for a batch job or manually correct status is a potential source of cost and customer friction. The storefront may be visually polished while these operational problems remain hidden.

Our commerce work uses that full lifecycle to prioritise engineering. Sometimes the highest-value improvement is customer-facing; sometimes it is a WMS acknowledgement, catalogue import, queue monitor or admin tool that removes hours of daily manual work. Both can materially improve the commercial performance of the platform.

Useful information for an initial assessment

  • Current platform, catalogue size and order profile
  • ERP/WMS/PIM/CRM and other connected systems
  • How pricing and inventory are owned
  • Checkout, payment and carrier dependencies
  • Known operational workarounds or reconciliation tasks
  • Commercial roadmap and major trading periods
Delivery models

Use the level of ownership that fits your team

Defined project

Midoriweb owns an agreed scope with clear milestones, acceptance criteria and release responsibilities.

Specialist workstream

Bring us into one technically difficult area while your existing team or agency owns the wider programme.

Team augmentation

Add developers to your existing process for a fixed period or an ongoing roadmap.

Ongoing technical partner

Combine support, maintenance, monitoring and planned improvement under continuing technical ownership.

Frequently asked questions

Questions worth answering before work starts

Do you work with platforms other than Magento?

Yes. Magento is a major specialism, but wider eCommerce work can include WooCommerce, Shopify-related development, headless architectures and custom applications through our broader team.

Can you improve the existing store without a rebuild?

Often. Performance, integrations, UX, infrastructure or technical debt can frequently be addressed incrementally.

Can you integrate ERP and WMS systems?

Yes. Connected commerce is a core capability and we design around data ownership, reliability, retries and reconciliation.

Can you support B2B eCommerce?

Yes. Requirements can include trade accounts, account pricing, purchasing permissions, quote or approval workflows and complex catalogues.

Can you help decide whether to replatform?

Yes. We can assess technical constraints, operating cost, roadmap needs and migration risk before recommending change.

Can you provide ongoing developers?

Yes. Retained support, dedicated developers and fixed-term teams are available.
