The PrestaShop marketplace has thousands of modules. Yet almost every store we manage has at least one feature no module does exactly the way it is needed: an odd shipping rule, a reseller price list, an export for the ERP, a badge that should appear only in certain cases. Here is when to buy, when to build, and what to expect in costs.
Ready-made or custom?
Buy a ready-made module when:
- the feature is standard (reviews, cookie banner, a well-known payment gateway);
- the module has recent updates, real reviews and active support;
- you do not need to modify it to make it work the way you want.
Build a custom module when:
- the feature depends on your process (pricing, shipping, stock, price lists);
- you would need two or three modules combined, with the risk of them fighting;
- the ready-made module exists but you would have to “adapt” it, i.e. edit its code and lose updates;
- you need to integrate an ERP, a carrier or an external service.
Rule of thumb: if you are about to buy the third module to solve the same problem, stop. A custom module costs less and does not break the others.
What a custom PrestaShop module costs
Market prices in Europe in 2026 for a qualified developer:
| Type | Examples | Cost | Timeline |
|---|---|---|---|
| Fix or small task | bug, module conflict, change to an existing module | €100 – 300 | 1 – 3 days |
| Simple module | badges, extra product field, shipping rule, CSV export | €500 – 1,500 | 1 week |
| Advanced module | B2B price lists, configurator, cron, dedicated admin UI | €1,500 – 5,000 | 2 – 4 weeks |
| Integration | ERP, warehouse, carrier, e-invoicing | €1,000 – 8,000 | 1 – 6 weeks |
At rivoluzionif: fixes for €149 within 48 hours, simple modules from €690, advanced modules from €1,900, integrations from €990. All fixed price, with documented code you own. Details on the modules, plugins and integrations page.
What a good module must contain
A well-written module is invisible: it works, it updates, it does not slow the store down. Concretely it must have:
- Respect for PrestaShop conventions: official hooks, no core changes, compatibility with your version (1.7 or 8.x) and your theme.
- A configuration panel in the back office, so you do not call the developer to change a parameter.
- Multi-language and multi-store handling if you use them.
- Error logs and clear messages, especially for integrations.
- Documentation: what it does, how to configure it, what happens when you upgrade PrestaShop.
- Staging tests before production, with a backup.
Questions to ask before paying
- Will I own the code? (The answer must be yes.)
- Does it work with my PrestaShop version and my theme?
- What happens when I upgrade PrestaShop?
- Is there a bug warranty? For how long?
- Do you deliver documentation?
- What does a change cost in six months?
If the developer dodges one of these questions, you are about to buy a future problem.
Typical case: the “odd” shipping rule
A store selling bulky goods must apply a different rate for islands, a surcharge for products over 30 kg and free shipping over €300, but only for B2B customers. With ready-made modules you would need three, and one case would still be uncovered. A custom module of this kind costs around €900-1,200 and is configured from the back office in ten minutes. It is the kind of work we do every week.
In short
Ready-made modules are fine for standard features. As soon as the feature depends on how you work, custom code costs less over the medium term, does not break the store and stays yours. Demand a fixed price, documentation and a warranty: they are the minimum.
