Every online store has something that off-the-shelf solutions don't cover: special pricing, a courier or ERP integration, a shipping rule or an internal process. That is where a custom PrestaShop module comes in.
At Hot Web Design we have developed more than 50 modules of our own for PrestaShop, and we write new ones when the available solutions don't meet a need properly.
When do you need a custom module?
- When the feature you need doesn't exist in any ready-made module.
- When a ready-made module only covers the need with compromises or excessive configuration.
- When you need an integration with an external system, such as an ERP, courier, bank or sales platform.
- When several modules conflict with each other or slow the store down.
- When a repetitive manual task in the back office can be automated.
The kinds of modules we develop
Our module catalog shows the range of our work:
- Shipping and couriers: voucher creation and tracking, such as our modules for ACS and Speedex.
- Payments: for example IRIS payments, deferred payment and an installment calculator.
- B2B features: a private shop, ask for price and quantity rules.
- SEO: SEO rules, URL redirects and product reviews.
- Store management: a bulk product editor, product export and order printing.
- AI: MCP Server, UCP Server and AI product descriptions. See all our AI solutions for PrestaShop.
- ERP: product matching and synchronisation modules. See PrestaShop ERP integration.
If one of our existing modules already covers your need, we recommend it before any new development.
How we develop a custom module
- Understand the need: what the module must do, who will use it and with what data.
- Check the alternatives: if a reliable solution already exists, you don't need to pay for new development.
- Specification: we agree the functionality, the back-office settings and the storefront behaviour.
- Development with the mechanisms PrestaShop provides, so the module doesn't depend on changes to the platform's core.
- Testing with the data and modules your store already uses, before it goes on the live store.
- Support and updates as your store and PrestaShop evolve.
Why the way a module is written matters
A module that edits core files or relies on shortcuts may work today and break at the next upgrade. That is why we write our modules for current PrestaShop versions, with attention to speed and data security.
We keep up with the platform. In our article on PrestaShop 9.2, for example, we explain what changes for module developers.
Frequently asked questions about custom PrestaShop modules
Why choose a custom module over a ready-made one?
When a ready-made module meets the need properly, it is usually the most economical option and we will recommend it. A custom module makes sense when the feature is specific to your business or when ready-made solutions force compromises.
Will the module affect PrestaShop upgrades?
We build modules with the mechanisms the platform provides, so no core changes are needed. Before any PrestaShop upgrade, every module is checked for compatibility. See also PrestaShop upgrade and migration.
Can you connect PrestaShop to the system I already use?
Usually yes, as long as the system offers a way to exchange data, such as an API or files. We check this during the analysis, before development starts.
Do you provide support after delivery?
Yes. We provide technical support and updates for the modules we develop.
