An osCommerce Development Company For Stores Still Trading
osCommerce is legacy software and we will not pretend otherwise. If your store still takes orders, the job is keeping it safe and supported: PHP upgrades, patched code, payment modules that still settle, and a straight answer on whether staying is the cheaper option.

What Our osCommerce Development Company Does
An osCommerce development company is a maintenance business, not a launch business. The code is old, the core has usually been hand-edited, and the modules were written for a PHP that no longer exists. So the work is finding what still runs, replacing what does not, closing the doors that have been open for years, and telling you honestly how long staying put remains the sensible answer. That last part is the part nobody else says out loud.
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. Store owners come to us when a host announces a PHP cutoff and the original developer has been unreachable for years.
What An osCommerce Job Covers
A read of the code before anything is quoted: what was hand-edited in core, which contributions are still doing work, which PHP calls no longer exist, and what would actually break on the next host upgrade.
Security handled as the first job rather than the last: the admin locked down, file uploads and inputs checked, known exploit paths closed, and the platform patched to the most current build it can take.
Payment modules brought back to something that settles: gateways still supported by the provider, current TLS and API versions, and a test transaction you watch end to end before it goes live.
PHP kept ahead of your host, not behind it. Removed functions rewritten, deprecated calls cleared, and the store proven on the version your provider is about to move you to.
Work you can inspect: staging first, code review on every merge, a written test pass before deploy, and tickets on your own board rather than a monthly summary email.
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 osCommerce Owners Screen A Development Partner Hard
- Ask whether they have actually worked on a store this old. Reading hand-edited core from a decade ago is a different skill from writing new code, and most teams have never done it.
- Ask what they will do about PHP. Hosts retire old versions on their own schedule, and a store that only runs on a build nobody supports is a deadline nobody told you about.
- Ask about the admin. It is the oldest and most probed part of these stores, and a vendor who has not mentioned it has not looked at the real risk.
- Ask whether your payment modules still meet what the gateway supports. Providers retire old protocols without much notice, and the first sign is a settlement that never arrives.
- Check the exit before you need it. The repository, the hosting account and the database all sit in your own name, so changing supplier is administration rather than a fight.
- Ask them to say when staying stops being worth it. Any vendor whose answer is never is selling you retainers rather than giving you a view.
How An osCommerce Project Starts With Us
Every project starts with a free 45-minute scoping session. No slide deck, no sales script. You bring the store, the hosting details and the list of things that worry you; you leave with a plan and an order of work.
We are selective about new projects and cap how many we run at once, because the scoping is the product. We do not build new stores on osCommerce, and we will say so when moving is the better call.

Common Challenges
Why Do osCommerce Stores Break?
Six patterns behind almost every osCommerce store that becomes a liability. All six come from age, not from neglect.
Core Hand-Edited
01
These stores were built by editing core directly, because that was how it was done. Nothing was documented, so every file has to be read before anybody can safely change a single line of it.
PHP Calls Removed
02
Functions the store depends on were deprecated, then deleted from PHP entirely. The site works until the host moves you, and then large parts of it simply stop.
Gateway Stops Paying
03
A payment module written years ago still looks fine in the admin, but the provider retired the protocol behind it. Orders come in and the money never arrives.
Admin Left Open
04
The admin still sits at its original path with a password from years ago and no IP restriction. It is the most probed part of any store of this age, and it is where damage starts.
Contributions Stacked Up
05
Ten years of add-ons were installed by copying files over each other. Two of them touch the same function, and nobody can tell which version of that file is currently the live one.
Nobody Left Who Knows It
06
The developer who built it is long gone and the community around the platform is quiet. The store still earns, and nobody dares touch it in case it stops.
Recognise a few of these? Let us fix them properly.
Our osCommerce Services
Our 6 osCommerce Development Services
Six ways to buy osCommerce work from one accountable vendor. Run one, or run several in parallel under a single contract.
Security & Patch Programme
01
The admin locked down, inputs and uploads checked, known exploit paths closed and the code brought to the most current build it can take, with a written record of every change.
PHP Version Upgrades
02
Removed and deprecated calls rewritten, database access modernised, and the whole store proven on the PHP version your host is about to move you onto, before they move you.
Custom Module Building
03
osCommerce module development for shipping, tax, exports and feeds, written cleanly and documented so the next person can read what we did.
Phoenix Upgrade Projects
04
For stores staying put, a staged move onto the maintained community fork: a clone, an inventory, a costed fix list, a rehearsal, then a switch in your window.
Integrations And APIs
05
The services behind the store, built by our own API development practice: accounting exports, courier bookings and stock feeds.
Support & Maintenance Plans
06
osCommerce support and maintenance on a retainer: monitoring, backups you can restore, small releases and somebody who answers when the store misbehaves.
Not sure which piece you need first? Let us scope it together.
Why Choose Us
What Makes Our osCommerce Development Different
The details that decide whether a legacy osCommerce store stays safe or turns into a liability.
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.
We Read The Old Code
02
Hand-edited core from a decade ago is a reading job before it is a coding job, and we quote only once we have actually read it.
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.
An Honest Verdict
04
We say when a platform has stopped earning its keep, even when that means a smaller engagement for us. You get a view, not a retainer pitch.
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 osCommerce Development Questions
Almost all of it is maintenance on stores that already exist. An osCommerce development company reads code that was hand-edited years ago, rewrites the PHP calls the language has since removed, locks down an admin that has been probed since it went live, replaces payment modules the gateway no longer supports, builds the odd custom module, and gives you a straight view on how long the platform is still worth keeping.
Yes, thousands of stores still run on it and still take orders, but it is legacy software and the community around it is a fraction of what it was. It is a maintenance platform now, not a growth one. If your store earns, the honest answer is usually to make it safe, keep it patched and plan on your own timetable rather than panic. If you are choosing a platform today, choose a modern one. We would not build a new store on osCommerce.
Cost follows the state of the code, not the size of the catalogue. A store close to a standard build prices very differently from one where core was hand-edited and ten years of contributions were copied over each other. PHP version, module count and the security backlog move it more than product count. We read it first, then price it.
Ask whether they have worked on a store this old, and what they found last time. Ask what they will do about PHP, the admin and the payment modules, in that order. Ask to see the code review before the invoice. Then ask them to say when staying stops being worth it. A vendor whose answer to that is never is selling retainers.
You do, from the first day. The repository, the hosting account, the domain and the database sit in your own name, and NDA and IP assignment are signed before anyone gets access. Every module, template and script written on the engagement is assigned to you outright, with no licence-back and nothing you keep renting.
We work across the 2.2 and 2.3 lineage, including the Bootstrap editions, and the maintained community fork that carries the platform forward. PHP is usually the first question, because functions these stores rely on were removed from the language entirely, so a host upgrade can take large parts of a working site offline overnight.
In most cases yes, and it is the work we start with. The admin gets a new path, real credentials and access restrictions, uploads and inputs are checked, database access is rewritten away from unsafe patterns, known exploit paths are closed, and the code is brought to the most current build it can take. Then we monitor it.
Stay while the store earns, the code can be made safe and your roadmap is small. Move when features you need are impossible, the security backlog keeps regrowing, or maintenance costs more each year than it saves. We will put that view in writing, with numbers. If moving is the answer, here is how a platform move is planned and run.
