Features you will not find in ready-made modules
There are many ready-made modules for PrestaShop, but not every process can be handled with them. When your store needs unusual pricing, its own order logic, a connection to an in-house system or a feature nobody has built yet, the best solution is a module written for your needs.
We write modules according to PrestaShop standards — using the platform’s mechanisms instead of changing its core. This keeps the store updatable and the module keeps working after a version change. We also develop and fix the modules you already have, and when you move to a new version of the platform we adapt them as part of a migration to PrestaShop 9.
What we do
Custom modules
We design and program features for a specific process: from changes to the cart and pricing to your own tools in the store’s back office.
Integration modules
We connect the store with external systems such as ERP, wholesalers or courier services when a ready-made integration does not meet the requirements.
Fixes and development
We fix bugs, add features and clean up the code of modules you already have in your store — including those written by other developers.
Adapting to new versions
We update modules so that they work on new versions of PrestaShop and PHP.
Documentation
Every module comes with technical documentation and a configuration guide, so it is easy to use and develop further.
Maintenance
We maintain and develop modules in the long term, as your store grows.
Where a custom module works best
A dedicated module most often solves problems that cost the store time or sales. These are the areas where such solutions are needed most often.
Prices and discounts
Individual price lists, discounts for customer groups, quantity thresholds and rules the standard configuration cannot handle.
B2B sales
Company accounts, wholesale orders, minimum quantities and prices visible only after logging in.
Products and configurators
Unusual variants, products assembled from components, calculators and extra fields on the product page.
Logistics and shipping
Custom shipping cost rules, split orders and support for several warehouses.
Documents and exports
Exporting orders and products to files, reports and summaries for your company’s departments.
Back-office tools
Features for store staff that shorten everyday work with orders and the catalogue.
How the process works
1
Requirements analysis
We learn the process the module is meant to handle and check whether a ready-made solution would be enough.
2
Design
We design how the module works, its settings and the places in the store where it will appear.
3
Development
We write the module according to PrestaShop standards and with future updates in mind.
4
Testing
We test the module on a copy of the store, together with your other modules and theme.
5
Deployment and support
We install the module in the store, hand over the documentation and keep developing it.
How much does a custom PrestaShop module cost?
The cost depends on the complexity of the feature. The estimate is influenced by:
- the complexity of the logic the module has to handle,
- where the module works — the storefront, cart, back office, e-mails,
- connections with external systems,
- the PrestaShop and PHP versions the module has to support,
- the scope of testing and documentation.
We prepare the estimate after analysing the requirements, and split larger modules into stages. Request an estimate or get in touch.
Why Appinet
We know the PrestaShop architecture and write modules that follow its standards: without touching the platform core, with updates and future development in mind. The module becomes part of your store, so we also take care of its performance and security, and every module comes with documentation. If a ready-made module will do the job, we will tell you honestly.
Frequently asked questions about PrestaShop modules
Will a custom module survive a PrestaShop update?
We write modules according to the platform’s standards and without changing its core, so store updates usually do not break them. When moving to a new major version we check the module and adapt it if needed.
Ready-made or custom module — which should I choose?
If a ready-made module meets the requirements, it is usually cheaper and available sooner — in that case we recommend it. A custom module makes sense when the process is unusual, ready-made solutions need many workarounds or several modules would have to work together.
Can you fix a module written by someone else?
Yes. We analyse the code, fix bugs and develop the module further. If its quality makes further development difficult, we suggest rewriting the key parts.
Will the module slow down my store?
We design modules with performance in mind: we limit database queries and unnecessary scripts, and check the impact on the store’s speed before deployment.
Will I get documentation?
Yes. Every module comes with technical documentation and a description of its configuration.
Will you look after the module after deployment?
Yes. We maintain and develop modules in the long term: we fix bugs, add features and adapt them to new PrestaShop versions.
