PrestaShop developer for custom development, repairs and support

When your store needs more than another setting

Orders are coming in, but someone still copies their details into another system. A customer selects a product variant and sees the wrong availability. A module update makes a carrier disappear from checkout. These are the moments when you need a developer who can connect the technical details to the way your business works.

As a PrestaShop developer, I help with individual repairs and the ongoing development of online stores. I want to understand what you need to accomplish and what your customers should be able to do easily. A useful change might reduce work during dispatch, make a product page clearer or reliably pass orders to your accounting software. That practical result guides the work.

What I can develop, improve and repair

Custom PrestaShop development and modules

Do you need different pricing rules, additional order information or a feature that an existing module cannot provide? I first review what your current setup can do. If custom development is the right approach, I can build a PrestaShop module or adapt an existing feature. The design takes account of your store version, theme and related modules. For multilingual stores, I also consider translated content and the way each language is managed.

Checkout errors, module conflicts and back office problems

A failed payment or an error when saving a product needs a different priority from a visual adjustment. I investigate when the problem occurs, who it affects and what changed before it started. Relevant modules and available error logs help identify the cause. After the repair, I check the connected steps as well: removing an error message does not, by itself, prove that a customer can complete an order.

Connections to accounting, stock and other systems

Manual data transfers take time and create opportunities for mistakes. I can connect PrestaShop to your business systems for orders, products, stock or shipment status. We agree which system owns each piece of information, when it should be synchronised and how a failed transfer should be reported. Repeated processing also needs attention, so the same order does not become a duplicate in another system.

Theme changes and performance improvements

I can adapt product pages, variants, categories and mobile navigation. When a store is slow, I start by measuring the problem. A module, database query, theme or server can all contribute. I focus on the actual cause and compare the result after the change. The aim is easier shopping and smoother administration; the improvement achievable depends on your store's current condition.

Upgrades, hosting moves and ongoing support

Before an upgrade or hosting migration, I review important modules, custom changes and the data your business depends on. We plan the transfer and the checks for orders, customers, catalogue data and page addresses. I can also provide ongoing PrestaShop support, so later requests go to someone who already understands how your store fits together.

How working with a PrestaShop developer works

We first define the result. What is failing today, how often does it happen and what should work differently? Describe it in your own words. For an error, a sequence of steps that reproduces it is useful. For a new feature, an example from your daily work usually explains more than a long technical specification.

I propose an approach and we agree the scope. I explain what needs to change, what depends on it and what could affect the cost or schedule. If a reliable estimate requires further investigation, I say so before we start and we agree that diagnostic work separately.

I prepare and verify the change. For larger interventions, I use a test copy of the store and arrange a backup of the affected parts before deployment. Depending on the change, checks include related features, mobile shopping, delivery, payment and order creation. At handover, I explain what changed and how to use the feature.

Experience that helps with the decisions

I have worked with PrestaShop every day for more than 14 years. That experience is particularly useful when choosing an approach. Another module may solve a problem, but it may also introduce a conflict or extra maintenance. I therefore review the tools you already use and the dependencies between them.

I favour standard PrestaShop extension mechanisms where they suit the task, with future updates and everyday administration in mind. You should be able to understand what the work will achieve, what it requires and how we will know it has succeeded. Technical detail should support those decisions.

What determines the cost and what to send me

The cost depends on scope, the condition of the store and its connections to other systems. Similar symptoms can have very different causes. After an initial discussion, we agree how to price the work and how to proceed. To get started, send me:

• Your store address and PrestaShop version, if you know it.
• The problem or change you have in mind and its effect on your work.
• An error screenshot or an example product or order that illustrates it.
• Whether the store is currently disrupted or this is planned development, and your preferred timing.
