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 2008, a fixed price rather than an open-ended estimate, and direct access to the two people who write the code.
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. Our CoreCRM platform 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:
20 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.
Working with Dev Partners to redesign and modernise our WMS system: the whole process has been thoroughly professional from the outset and a delight to work with. Cannot recommend enough.
Great agency. Have used Dev Partners for several years and they have built 20+ sites for us, in addition to taking on our legacy websites, upgrading and maintaining. Easy to work with and some great practical ideas to improve our digital offerings.
Jones Hire have been working with Dev Partners on several projects, which have been very successful. They linked our catering database to a new improved website so clients can easily place and update orders, created a custom warehouse picking app to fulfil all our challenging requirements, and are currently developing a custom transport app to streamline our loading and delivery process.
We have been trying to reinvent our website for over 5 years, trying to make it convert and failing each time. Spoke to Rob at Dev Partners, the team helped create our new site and the improvement was instant.
We have been working with Rob and the team for about 10 years now. Dev Partners helped us build a completely bespoke CRM from scratch which manages our daily business and is always well maintained. We have been able to use the system and roll it out in our new franchise branches.
We collaborated with Dev Partners on the front end of a fairly complex telemarketing platform. Rob and Jason took the time to properly understand the moving parts, asked the right questions, and delivered a clean, intuitive interface that's made the system far easier for our team to use.
I have been working with the team at Dev Partners for the last 3 years and we have always been impressed with the speed in which they act on things for us, along with the honest open communication. The team are a valuable and vital part of our supply chain.
We've had a program for our business in the electronic security sector that Dev Partners developed and keep up to date. They've never let us down, always there when needed. Thanks Rob and the team.
Dev Partners have been working with us for just over 2 years. They have significantly upgraded and redesigned our existing web platforms, and always deliver a first class service.
Dev Partners helped us build an event website. The team were very knowledgeable, easy to work with and quick to deliver a high quality product.
Working with Dev Partners has been an exceptional experience. Their team is highly skilled, professional, and committed to delivering results. What truly sets them apart is their communication and transparency; we always felt informed, supported, and confident.
We've worked with Dev Partners a few times to support us on bespoke web build tasks. They're very easy to work with, approachable, and explain the detail in a way that's understandable. A great partner for technical issues at sensible prices.
Excellent customer service backed up with solid experience. As a media business we have had five websites built by Dev Partners. I would certainly recommend them.
Found Dev Partners and they were great, nothing too much trouble. They managed to help us with integrating our old existing system with Shopify.
I've worked with Rob and his team off and on for many years and have always found them to be professional, knowledgeable, and best of all, they listen to their clients and deliver what is required.
We have worked with Dev Partners for 7 years and can highly recommend them for their expertise and excellent customer service.
If you've been burned by a developer before, or you're nervous about committing to a project of this size, these are the questions worth asking any agency you're considering. Here are our honest answers.
This is the most common thing we hear, and it is a completely reasonable concern. We cannot guarantee a different experience just by saying so. What we can tell you is how we work: you deal directly with Rob or Jason throughout, not with an account manager who relays messages to a development team you never speak to. Every project has a fixed scope agreed before development starts. You see working software at regular intervals, not a finished product six months later that does not match what you asked for. Most of our clients have been with us for years. If you want to speak to some of them, ask us and we will arrange it.
Scope creep is the main reason software projects go over budget, and it almost always happens because the requirements were not properly understood before the price was set. We do not give quotes before we understand the problem. The analysis phase exists specifically to surface the complexity before we commit to a price. Once scope is agreed, we work to it. If you want to add something that was not in the original scope, we quote for it separately rather than absorbing it into the project and adjusting the final invoice. You always know where you stand.
No. The code we write is yours outright from day one. It is written in standard, well-documented PHP using mainstream frameworks that any competent developer can read and maintain. If you wanted to move to a different developer in the future, you could. We would hand over the codebase cleanly and there would be no lock-in. The reason most of our clients stay with us for years is not because they are stuck. It is because they have found a development partner that works and they do not want to change.
Size is not what makes a software project succeed. Structure, communication, and technical depth are what make it succeed. We have built systems for Telegraph Media Group, CDS Global, Motel Rocks, and AX Paris. These are not simple projects. The advantage of working with us over a larger agency is that the people who scoped your project are the people building it, and you can reach them directly when something needs a decision. At a larger agency you get account managers, project managers, and a development team you have never spoken to. That is not better. It is just bigger.
Most of our clients do not have a technical person internally. That is often why they come to us. We translate the technical side into plain language, flag decisions in terms of business impact rather than code complexity, and document everything so your team can use and understand the system without needing a developer in the room. The goal is always to make the software something your team can run confidently, not something they depend on us to operate.
They underestimated because they quoted before they understood the requirements properly. We do not give timelines before we have done the analysis. When we do give a timeline, it is based on what we actually found during scoping rather than an optimistic estimate designed to win the work. We also build in contingency rather than assuming everything will go smoothly. Software projects encounter unexpected complexity. The question is whether you planned for it.
We are still here. This is not a project shop that delivers and moves on. Most clients move to a support and development retainer after launch because software changes as the business changes. For the period immediately after go-live, we monitor closely and fix any issues quickly. Because we built it, we can diagnose and resolve problems faster than any third party coming in cold. The post-launch relationship is something we consider part of the project, not an optional extra.
A quote that varies that much almost certainly means the agencies were quoting different things. The £5k quote probably assumed the requirements are simpler than they are, skipped proper analysis, or plans to deliver something that technically works but does not do what you actually need. The £80k quote likely includes significant agency overhead, management layers, and a team that has never spoken to you. Our quotes are based on a proper understanding of the requirements. We will explain exactly what is driving the number, and if it surprises you, we will talk you through why.
Dev Partners has been trading since 2008, run by the same two people throughout. We did not take investment, we do not have a growth target that requires us to sell or scale aggressively, and we have no intention of going anywhere. We are a sustainable, profitable small business that looks after a relatively small number of clients very well. That model has not changed in 17 years. We also write all code to a standard that means any competent PHP developer can take it over if the worst did happen. You are not betting your system on our survival.
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 2008, 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.
