Custom e-commerce development: WooCommerce, PrestaShop and Magento
Your shop, the features it’s missing.
Every online shop eventually reaches the point where off-the-shelf plugins aren’t enough: a price list with rules all its own, a management system to connect, a checkout with one step too many. We build custom plugins, modules and integrations for WooCommerce, PrestaShop and Magento - the features that are missing, built the way the platform itself would build them.
Need server-side support instead - hosting, caching, security? Take a look at WooCommerce support, PrestaShop support or Magento support.
Overview
We know these platforms from both sides: we write code that follows their conventions - hooks, overrides, official APIs - and we keep them running in production, so we know what holds up under real traffic and what breaks at the first update. It’s a practical difference: a module can work perfectly in a demo and then multiply queries under load, or clash with checkout caching. Anyone who’s never run a shop in production discovers this after the fact; we design for it beforehand.
The scope is clearly defined: we don’t build custom e-commerce platforms from scratch, and we don’t work on SaaS platforms like Shopify. We start from the platform you’re already using - or the one it makes sense to adopt - and build what’s missing from it: the particular pricing logic, the connection to your management software, the checkout trimmed to essentials. We write the code and keep it running in production: that goes for your shop too.
Typical problems we solve
- Orders copied by hand into your management software → two-way integration that syncs orders, stock and price lists with the ERP.
- An off-the-shelf plugin does almost what you need → we build the missing module to the platform’s standards, without touching the core.
- Checkout with too many steps and abandoned carts → we streamline the funnel with conditional fields and custom rules.
- A module bought years ago is blocking a platform update → code audit and adaptation, or a rewrite, compatible with current versions.
- B2B pricing, per-customer price lists or tax rules no extension handles → pricing logic built around your actual contracts.
- Catalogue updated by hand from a CSV every week → automated imports with validation, logging and verifiable results.
- The payment gateway or courier you use has no official module → we integrate their API - webhooks and tracking included.
What’s included
- Custom plugins and modules: the feature you need, built with the platform’s official hooks, overrides and APIs - never by modifying the core.
- ERP and management software integrations: orders, stock, customer records and price lists synced reliably, with queues, retries and error logs.
- Payments and shipping: gateways and couriers connected via API, webhooks handled correctly and order statuses always consistent.
- Checkout and conversion: customisations to the purchase funnel - fields, steps, validation rules - measured against real customer behaviour.
- Back-office automation: invoicing, price lists, catalogue and notifications without repetitive manual work.
- Audits of existing modules: reviewing and securing code written by others, with an honest estimate: fix it or rewrite it, we’ll tell you upfront.
- Ongoing compatibility maintenance: custom code kept compatible with new platform versions, verified on staging at every update.
Stack and technologies
We develop in PHP following each platform’s architecture: hooks and the REST API for WooCommerce, modules and overrides for PrestaShop, modules with dependency injection for Magento. When an integration deserves to live outside the shop - a middleware layer for the ERP, a sync service - we build it with Laravel, with queues on Redis to absorb webhook spikes. Data lives on MySQL/MariaDB; all code is versioned in Git, with a staging environment and repeatable deploys. If we also host the shop, the servers run on Debian or Ubuntu - AlmaLinux, Rocky Linux or other distributions on request - mainly on Google Cloud, with AWS and DigitalOcean as alternatives. No dependency on us: the repository is yours, documentation included, and any PHP developer can pick up the work.
A real-world example
A B2B distributor on PrestaShop was receiving orders online but copying them into their management software by hand: two people tied up every morning, stock levels never aligned, sales of items that were actually out of stock. We built a module that talks to the ERP’s REST API: orders now go through automatically with a tracked outcome, stock levels flow back to the shop at regular intervals, and errors land in a readable log instead of vanishing without a trace. The module follows PrestaShop’s standards, so platform updates don’t touch it. Result: no more double entry, stock kept aligned, and out-of-stock order cancellations down to isolated cases. The client has the code in their own repository, with documentation to keep evolving it even without us.
Who it’s for
- Growing shops that have outgrown what standard plugins can do.
- Companies selling online that need their shop, management software and warehouse to talk to each other.
- B2B businesses and distributors with price lists, contracts and pricing rules that generic extensions don’t cover.
- Agencies looking for a white-label technical partner for the custom side of e-commerce projects.
How we work
Analysis comes first: we understand the process, check whether a solid off-the-shelf solution already exists - and if it does, we’ll tell you, even if it means selling you fewer hours - and only then write code. Every module is versioned, documented and tested on staging with realistic data before it touches production. Quotes are free, with a reply within one working day; we bill at €75/hour or by project, and for ongoing work many clients use hour packages, which never expire. And if we also manage the shop on the server side, updates and performance stay our problem, not yours: the same team is accountable for both the code and the server.
Frequently asked questions
Do you also build on SaaS platforms like Shopify?
No: we only work on the self-hosted platforms we also know from the server side - WooCommerce, PrestaShop and Magento. It’s the only way to be accountable for the whole chain, from code to production.
How much does a custom plugin or integration cost?
Our hourly rate is €75/hour; on a project basis, indicative ranges start at €1,200 for a custom plugin or module and €3,000 for an integration with management software or an ERP. A detailed quote is free, with a reply within one working day.
Will the module survive platform updates?
Yes, because we develop following each platform’s official APIs and conventions - hooks for WooCommerce, modules and overrides for PrestaShop, standard modules for Magento - without ever touching the core: the platform stays safely updatable.
Can you fix a module written by someone else?
Yes: we start with a code audit, estimate the work and tell you honestly whether it’s worth fixing or rewriting. Sometimes a rewrite costs less than three rounds of patches.
Do you also build complete e-commerce sites from scratch?
No: on the storefront side we always start from WooCommerce, PrestaShop or Magento, which already cover catalogue, cart and orders. If you need custom software around the shop - management tools, portals, APIs - we build that with Laravel.
Who maintains the module after delivery?
Whichever you prefer: we hand over versioned, documented code that any PHP developer can pick up, or we take care of it ourselves with hour packages that never expire (5 hours at €350, 10 at €660, 20 at €1,200), with Mon-Fri 10:00-18:00 coverage.
Do you also work at night or on weekends?
Guaranteed only for clients with an active on-call plan, and only for real P1 emergencies: production down, data loss, active security incident. On-call is a monthly retainer with limited seats, available on systems we manage and, after a case-by-case assessment, on others too: prices and rules are on the On-call page. Without a plan, coverage is Mon-Fri 10:00-18:00 and out-of-hours work is best effort: it may happen, but it is neither guaranteed nor something you can demand. Night or holiday work planned at least 20 days ahead remains available to everyone, at the surcharged rate.
