PrestaShop Store Development
A PrestaShop Development Company For Stores Built To Last
PrestaShop is open source, self-hosted and extremely extensible, which is exactly why so many stores end up stuck on an old version. We build with proper modules instead of overrides, keep the upgrade path open, and treat multistore, tax and language as design decisions rather than afterthoughts.

What A PrestaShop Development Company Does
A PrestaShop development company earns its fee in the places the platform rewards discipline. Overrides, which solve today's problem and block every future upgrade. Modules bought from a marketplace and then edited, so the vendor can no longer support them. A hybrid codebase where Symfony controllers and legacy ones sit side by side. We build proper modules against the hook system, leave the override folder alone, and keep the store on a version that still receives fixes.
Stallyons is registered in Delaware as a US company, and our engineers work a time-zone window agreed before the project starts, with four-plus hours of daily overlap. You sign a US contract, run diligence on a US entity and pay one US invoice. Behind the work sits twelve-plus years of delivery across six continents and around thirty-five engineers, averaging four-plus years of production experience. Merchants come to us when a PrestaShop store has stopped being upgradable and needs that fixed rather than papered over.
What A Store Build Covers
A module inventory agreed before code: what each one does, who still supports it, which have been edited in place, and which get replaced by something small that we write and you own outright.
Customisation through the hook system rather than the override folder, so the store can take a PrestaShop update without a developer spending a fortnight working out what somebody changed and where.
A version and PHP plan you can read: where the store is now, which release it is going to, what each module costs to bring along, and how long the whole thing realistically takes.
Themes built as child themes on Smarty templates, so the parent stays intact and a design change never means editing files somebody else is going to want to update later.
Quality you can inspect: code review on every merge, automated checkout and tax tests, a staging copy that mirrors production, and work tracked on your own board.
One accountable vendor: one contract, one invoice and one entity for legal and finance to run diligence on, instead of a spread of contractors across four jurisdictions.
Why Buyers Screen A PrestaShop Development Agency Hard
- Ask what goes in the override folder. The honest answer is almost nothing. Overrides are the single most common reason a PrestaShop store can no longer be upgraded safely.
- Ask which PrestaShop version the work targets and which PHP version it needs. A store built for an unsupported pairing is already carrying a bill nobody has quoted for yet.
- Ask whether bought modules will be edited in place. Once they are, the vendor cannot support them and every update becomes your developer's problem instead.
- Ask how the theme is built. A child theme on top of the parent survives updates. A parent theme edited directly looks identical on day one and costs you the upgrade path anyway.
- Check the exit before you need it. Hosting, the repository, the domain and every module licence sit in your own name, so changing supplier is administration rather than a rescue.
- Ask for the release plan. A staging copy that matches production, a rehearsed database migration and a rollback route, all agreed before the first deployment.
How A PrestaShop Project Starts With Us
Every project starts with a free 45-minute scoping session. No slide deck, no sales script. You bring the catalogue, the version you are on and the modules you are stuck with; you leave with a plan and a timeline.
We are selective about new projects and cap how many we run at once, because the scoping is the product. If PrestaShop is the wrong home for what you sell, we will say so before you buy it.

Common Challenges
Why Do PrestaShop Stores Stall?
Six patterns behind almost every PrestaShop store that has to be rescued. All six start with a shortcut that saved a week.
Overrides Pile Up
01
Every awkward requirement was answered by dropping a file into the override folder. The store now works, and no upgrade can be applied without somebody first reverse-engineering what each one does.
Bought Modules Edited
02
A marketplace module was changed in place to fit. The vendor will not support it now, its own updates would wipe the changes, so it simply never gets updated again.
Stuck On Old Version
03
The store still runs 1.6 or an early 1.7 on a PHP version that stopped getting security fixes, and every quote to move it forward has looked like a rebuild.
Parent Theme Hack
04
The design was changed by editing the parent theme instead of building a child. It looks the same as a proper job and costs the store its upgrade path, silently, from day one.
Slow Admin And Catalogue
05
Product and order tables grew, caching was never configured past the defaults, and now the back office takes long enough that staff have stopped using half of it.
Access Held By Agency
06
Hosting, the repository and the module licences sit in a supplier account. Changing agency becomes a negotiation, because nobody else can deploy a change.
Recognise a few of these? Let us fix it properly.
Our PrestaShop Services
Our 6 PrestaShop Development Services
Six ways to buy PrestaShop delivery from one accountable vendor. Run one, or run several in parallel under a single contract.
Custom PrestaShop Builds
01
End-to-end delivery of a defined PrestaShop store: scope, design, build with proper modules, test checkout against real tax and payment rules, and launch with a named lead.
Theme Development
02
PrestaShop theme development as a child theme on Smarty templates, prototyped in Figma and delivered so the parent stays intact and updates stay possible.
Custom Module Development
03
PrestaShop module development against the hook system for rules no marketplace sells: pricing, fulfilment, back-office screens and your integrations.
Version Upgrade Projects
04
Moving 1.6 and early 1.7 stores onto a supported release and PHP version, module by module, with the override backlog cleared as part of the job.
Backends & Integrations
05
The systems behind the store, built by our own API development practice: accounting, fulfilment, CRM and product feeds, wired both ways.
Store Care & Maintenance
06
Security patches and module updates rehearsed on staging, uptime and checkout monitoring, and a monthly read on what is slowing the store down.
Not sure which piece you need first? Let us scope it together.
Why Choose Us
What Makes Our PrestaShop Development Different
The details that decide whether a store can still be upgraded two years and four hundred orders later.
A US Legal Entity
01
Stallyons is registered in Delaware. Your contract, your invoice and your legal recourse sit with a US company, not an unknown one.
Almost No Overrides
02
Customisation goes into proper modules on the hook system, so the override folder stays close to empty and upgrades stay ordinary work.
Overlap You Set
03
You choose the hours we share with your working day, and stand-ups, reviews and escalations all happen inside that window.
Upgrade Path Kept
04
Child themes, unedited marketplace modules and a documented version target, so the next PrestaShop release is a task rather than a project.
Reviewed Code
05
Every merge is reviewed against an agreed definition of done, on your board, where you can read it yourself.
One Contract
06
One contract covers the engagement, so procurement, legal and finance each deal with a single named counterparty.

FAQ
Frequently Asked PrestaShop Store Questions
A PrestaShop development company handles the parts of the platform that reward discipline and punish shortcuts. It builds customisation as proper modules on the hook system rather than as overrides, keeps bought modules unedited so their vendors still support them, builds themes as child themes on Smarty templates, and holds the store on a release and PHP version that still receives security fixes.
1.6 is the old architecture and is long past support. 1.7 introduced the Symfony-based back office, which is why upgrading from 1.6 is a project rather than a click: templates, modules and the theme all change shape. PrestaShop 8 continues that line, tightening PHP compatibility and finishing more of the migration to Symfony. Most stuck stores are on 1.6 or an early 1.7, and the honest answer is that the jump is large but bounded once the modules are inventoried.
Cost follows how many modules the store carries, how many of them have been edited in place, how much sits in the override folder, and whether you are building new or bringing an old store forward, so a figure before scoping is guesswork. The override backlog moves it more than the catalogue does. We scope first, then price, and itemise each phase.
Ask what they will put in the override folder, and be suspicious of any answer that is not “almost nothing”. Ask whether bought modules get edited in place. Ask whether the theme will be a child theme. Then ask which PrestaShop and PHP version the work targets. The answers tell you whether you are buying a store or buying a future rebuild.
You do, from the first day. Hosting, the domain, the repository, the payment accounts and every module licence are registered in your name, and NDA and IP assignment are signed before anyone gets access. Everything written on the engagement is assigned to you outright, with no licence-back.
Yes, and it is usually the right answer when no marketplace module fits. PrestaShop module development against the hook system gives you pricing rules, fulfilment steps and back-office screens that survive updates. Themes are built as child themes on Smarty templates, so the parent stays untouched and the store keeps its upgrade path.
For merchants who want open source, self-hosting, real multistore and full control of data, yes, and the 8.x line is actively maintained. It asks more of you than a hosted platform: you own hosting, updates and module decisions. If you would rather not run that yourself, our ecommerce development team can compare the options.
Often, and it is usually cheaper than starting again. We inventory the modules and the override folder first, then move the store forward in stages with staging rehearsals at each one. If you have decided to leave PrestaShop for a different platform entirely, that is handled by our ecommerce migration services team.
