Custom Software Development · Staines-upon-Thames · Surrey
Staines is one of the South East's strongest corporate-headquarters locations, helped by its Thames Valley position and proximity to Heathrow. Around those big-name HQs sits a far larger base of established SMEs and suppliers — the firms that rarely have a corporate IT department, and often run on ageing systems.

Staines-upon-Thames has long attracted national and regional headquarters — the kind of corporate base that includes household names in healthcare, energy, technology and engineering — drawn by the Heathrow corridor, strong transport links and costs below central London. It has even topped national rankings for business creation.
The big HQs have their own IT departments. The much larger population of established SMEs, suppliers, logistics operators and professional firms around them usually does not. They run on an accounts package, a stock or job system and a stack of spreadsheets, with workarounds that have quietly become load-bearing.
We fix the specific points where an ageing system is costing an established Staines business time and money — the report that takes half a day, the data rekeyed between packages, the process that lives in one person's head — carefully, without ripping out everything that still works.
These patterns turn up in established Staines businesses again and again. If more than one is familiar, it is worth a conversation.
The data exists. Someone extracts it, cleans it, combines it from three sources and formats it in Excel. Every week, the same half-day. A well-designed system produces it in seconds.
An order or job goes into one system. Someone types it into the accounts package. Someone checks a third. Three entries for one transaction, three chances for the numbers to diverge.
It works, roughly. Last time someone changed it, something broke. The person who built it has gone. So it stays, accumulating workarounds until the workarounds become the system.
One experienced person knows how it really works. If they are off or leave, things slow noticeably. Nobody wrote it down because nobody had to — until now.
The package you rely on still runs, but updates have stopped and integrations have broken. Your accountant is hinting you should move to something supported.
The gap is not a feature request. It is the specific way your business runs that no generic platform was built for, and you have been working around it ever since.
Staines is corporate-headquarters territory: the town hosts national and R&D bases for major organisations across healthcare, energy, engineering and technology, including names such as Bupa, Siemens, British Gas and Samsung's UK research operation. Those businesses run their own enterprise IT; the town is not, in itself, a cluster of independent bespoke-software agencies.
That leaves the established small and medium businesses around them comparatively underserved. Dev Partners focuses precisely there: bespoke internal business systems, system integrations and legacy modernisation for SMEs, suppliers, logistics operators and professional firms — the companies that need software shaped around how they work but do not have an in-house development team. We are Kent-based and straightforward about it: most work runs remotely, and we travel into Surrey when a project benefits from time on site.
What you get is a UK team that has done this since 2011, a fixed price rather than an open-ended estimate, and direct access to Rob and Jason, who are on every project.
Organisations named above are mentioned only to describe the local economy accurately; they are not affiliated with Dev Partners, and nothing here is a comment on them.
No grand rebuild. We find the one or two processes causing the most friction and fix those first, so you see a return before any larger work begins. Established businesses rarely need a complete overhaul — they need targeted fixes applied carefully.
Your accounts package, stock system and the rest can usually stay. We connect bespoke software to them rather than replacing them wholesale, so your systems share data instead of duplicating it.
For a business planning to be around for decades, the developer relationship matters as much as the code. Most of our clients have been with us for years, several over a decade. The same people are still here.
For the distribution and logistics operators along the Heathrow corridor: bespoke order, stock, warehouse and delivery systems that fit your actual operation, not a generic WMS.
Custom job management, scheduling, quoting, approval and sign-off workflows that codify how your business runs and remove the dependency on individuals carrying the process.
Migrating ageing databases and legacy applications to modern, maintainable platforms without disrupting operations — including COBOL, Access and early-generation PHP systems.
Connecting the packages you already run so data flows between them without manual re-entry: accounting, ERP, stock, CRM and e-commerce. If it has an API, we can connect it.
A CRM built around how you really manage accounts, pipeline or cases, not how a generic vendor assumes you do. An open-source CRM such as Krayin or EspoCRM as a starting point, or fully bespoke.
Pulling data from multiple sources into dashboards and reports that are always current, instead of someone spending half a day extracting and formatting spreadsheets first.
The relationships that matter most to us are the ones that have run for years. A selection of who we have built for and kept running:
19 clients. A few of their words.
A well-rounded team, ensuring a full suite of expertise & resource is always available. CDS Global have seen the successful completion of major projects over the years where Dev Partners' ability to grasp the underlying business needs to provide a future-proof solution has been invaluable.
We have worked with Jason & his team to develop our Shopify store, and the experience was outstanding from start to finish. The design is clean, modern, and perfectly aligned with our brand identity, while the build is fast, responsive, and easy to manage on the backend. They clearly understood our vision and delivered a store we're genuinely proud of. Highly recommend to any brand looking for a top-quality Shopify partner.
After ongoing issues and delays with our previous developers, we brought in Rob & Jason at Dev Partners to take over all our websites and bespoke software. What a breath of fresh air, fully focused, excellent pre-launch designs and clear communication throughout. Highly recommended.
BPC Energy Ltd turned to Dev Partners for a complete turnkey solution, and they exceeded our expectations. The team handled everything from project management to development and support with real care and attention. They understood what we were aiming for, stayed on top of every detail, and always delivered on schedule with excellent quality.

The questions we think every business should ask a software developer, including us. The honest answers are on our custom software page.
We are Kent-based, in Gravesend, around 55 miles from Staines-upon-Thames. Most development runs remotely as standard, and we travel into Surrey when a project benefits from time with your team in person. Where you are based makes no practical difference to the quality of the work.
That is exactly who we work with. Staines is known for its corporate headquarters, but around them sits a large base of established small and medium businesses, suppliers and operators. We build bespoke systems for those firms, who rarely have the in-house IT department a large corporate takes for granted.
Almost always. We connect bespoke software to the accounts packages, stock systems and other tools you already run, so you extend what works rather than replace it. The goal is your systems sharing data rather than duplicating it, without a disruptive big-bang replacement.
Yes. Modernising ageing databases and legacy software, including systems built on COBOL, Access or early PHP, is something we do regularly. We migrate data carefully and keep operations running throughout, rather than a cutover that brings everything down at once.
Established operators: logistics and distribution serving the Heathrow corridor, professional services, suppliers to the larger corporates, and growing businesses that have outgrown their original tools. Anywhere a generic package no longer fits how the business runs.
Since 2011, from our office in Gravesend, with the same two directors. Several client relationships have run for over a decade. For a business building on software it intends to run for years, that matters more than it sounds.

Operational software lives or dies on the details — the edge cases, the handovers, the one report nobody ever documented. We build it properly the first time, in-house, so it keeps pace with the business instead of becoming the thing everyone works around.
