Custom Software Development · Brighton & Hove · East Sussex
Brighton has one of the UK's densest digital and creative clusters. But behind the app studios and product startups sit hundreds of established Brighton & Hove businesses running on software that no longer fits how they work. We build the internal systems and modernise the legacy software those operators actually depend on.

Brighton & Hove is rightly known for its digital economy — a creative-tech cluster of well over a thousand businesses, employing many thousands of people, with a digital sector worth roughly as much to the city as tourism. It is one of the most concentrated tech scenes in the country, supported by a strong community around bodies like Wired Sussex.
But that headline cluster is mostly consumer apps, digital products, agencies and marketing technology. It sits alongside a much larger, quieter base of established Brighton and Hove businesses — professional and financial services, tourism and hospitality operators, healthcare, education, property — that run on internal systems built years ago. Information & communication and professional, scientific and technical work are the city's two biggest employment sectors, and a lot of that work depends on software that has quietly stopped keeping up.
That is the work we do. Not the next app, but the order system, the booking and scheduling platform, the data trapped across three packages, the report that takes half a day. We fix the specific points where an ageing system is costing an established business time and money — carefully, without ripping out everything that still works.
These patterns turn up in established Brighton 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.
A booking or order 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.
Brighton is well served for software and digital talent. The city is home to long-established firms such as One Beyond (building web, desktop and mobile applications from Brighton since the 1990s) and BrightMinded (a bespoke software developer founded in the early 2010s), alongside a large community of digital product studios, app developers and creative-technology agencies clustered around the Wired Sussex network.
Most of that ecosystem is geared toward consumer-facing products, mobile apps, and marketing and creative technology. Dev Partners works in a narrower lane: bespoke internal business systems, system integrations and the modernisation of ageing or legacy software for established operating businesses. It is a deliberately different focus, and a smaller field, which is why Sussex firms with that specific need often look beyond the obvious app-and-product agencies.
We are also Kent-based rather than Brighton-based, and we are straightforward about that: most development runs remotely as standard, and we travel into Sussex when a project benefits from time with your team in person. What you get is a UK team that has been doing this since 2011, a fixed price rather than an open-ended estimate, and direct access to Rob and Jason, who are on every project.
The firms named above are independent businesses mentioned only to describe Brighton's software landscape accurately; they are not affiliated with Dev Partners, and nothing here is a comment on the quality of their work.
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, booking system, 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 tourism, hospitality, events and service operators Brighton is built on: custom booking, scheduling, resourcing and despatch systems that fit your actual operation, not a generic SaaS template.
Migrating ageing databases and legacy applications to modern, maintainable platforms without disrupting operations — including COBOL, Access and early-generation PHP systems on infrastructure that needs replacing.
Connecting the packages you already run so data flows between them without manual re-entry: accounting, ERP, stock, CRM, booking and e-commerce. If it has an API, we can connect it.
Case, client, pipeline and compliance systems for the professional and financial services firms that make up a large share of the city's economy — built around how your firm actually works.
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.
Much of Brighton's well-known digital sector is weighted toward consumer apps, digital products and marketing technology. We work at the less glamorous end: the bespoke internal business systems, integrations and legacy modernisation that established operating businesses depend on. It is a different specialism, and a smaller field locally, which is exactly why Sussex businesses come to us for it.
We are Kent-based, in Gravesend, around 70 miles from Brighton via the M25 and M23. Most development runs remotely as standard, and we travel to Sussex when a project benefits from walking the process with your team in person. Where you are based makes no practical difference to the quality of the work.
Almost always. We connect bespoke software to the accounts packages, booking systems, 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 rather than early-stage startups: professional and financial services, tourism and hospitality operations, healthcare-adjacent businesses, education, and the back-office systems behind creative and digital firms that have grown past their original tools. Anywhere a generic package no longer fits how the business actually 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, a developer who still answers the phone in ten years matters more than it sounds.
How we help established businesses, and the areas we cover.
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.
