How do I add a feature my store doesn't have, without knowing how to code?
Gift packs, a notice per category, a configurator, purchase conditions by zone… Devellia programs the feature in your PrestaShop or WooCommerce store, tests it in a copy and installs it when you are convinced.
With an agency or a freelancer
- An hour of PrestaShop development costs around €80 ($89) with VAT. A simple module usually takes several hours, plus testing.
With a general AI
- It can write the module and, if you connect it to your server or your shop, even install it.
- You prepare the testing on a copy and the security review yourself. A 2025 study found security flaws in almost half of the AI-generated code it analysed.
- Setting up and maintaining those connections, reviewing what it does and fixing whatever breaks takes technical knowledge, time and money: a higher opportunity cost than asking someone who already has it all solved.
With Devellia
- You describe it with an example: "I want my customers to be able to create gift packs by choosing 3 products".
- You see the price before you start.
- Devellia programs it, checks the security of the code and tests it in a copy of your store.
- You install it when you are convinced. If something fails, it is undone.
- If it fits in your store as a change: €1.50 – €10.00 ($1.66 – $11.08)
- If it needs its own module or plugin: €15.00 – €60.00 ($17 – $66)
Estimated prices, VAT included. You pay what it uses and never more than the maximum we show you before you start.
Connections with third-party software (your ERP, marketplaces or payment gateways) are custom development: Devellia tells you before charging you anything.
