Custom software development by county
Detailed guides to the bespoke software firms in each county, with honest comparisons and what to look for.
Kent
Home county · Based in Gravesend · Serving the whole county
Kent is our home county. We are based in Gravesend and have built bespoke software for businesses across the whole of Kent, from the Medway towns to Maidstone, Ashford and Tunbridge Wells. Our full guide compares the other Kent software firms, what separates them, and who is best suited to which type of project.
Essex
A short drive across the river · Chelmsford, Braintree and beyond
Essex has a real spread of bespoke software firms, from Chelmsford and Colchester through Braintree and Southend. Our guide covers the Essex software companies worth considering and the questions to ask before you commit to one.
London
On the edge of the capital · Mid-market value vs city pricing
London has more software agencies than anywhere in the UK, and many are priced for enterprise or route the work offshore. Our guide is honest about where London firms excel and where a South East partner like Dev Partners offers better value and a direct line to the developers.
Sussex
Brighton's tech scene · East and West Sussex coverage
Sussex has a capable mix of bespoke software firms, from Brighton's digital scene to specialists across Crawley, Chichester and Worthing. Our guide breaks down what each one is actually good at so you can match them to your project type.
Surrey
Between London and the South Coast · Guildford to Reigate
Surrey has a strong cluster of bespoke software firms, with more company headquarters than almost any other county. Our guide covers the Surrey and South East firms serving the market and helps you identify what you actually need before you commit.
Custom software development elsewhere in the UK
We are based in Kent and these regions are served remotely, which we say plainly on every page. The guides are worth reading anyway: we checked every agency's address against its own contact page and Companies House, and a surprising number of them are not where their landing pages imply.
Hampshire
Delivered remotely from Kent · Southampton and the Solent
Hampshire has a real cluster of software firms around Southampton, and a much larger cluster of landing pages written by firms in Devon, London and Oxfordshire. Our guide names the ones with a verifiable Hampshire address and what each of them actually builds.
Yorkshire
Delivered remotely from Kent · Leeds, Sheffield and Wakefield
Leeds and Sheffield have long-established software consultancies, several of them older than the agencies competing with them. They are also far more different from one another than their websites suggest. Our guide sets out which is suited to what.
West Midlands
Delivered remotely from Kent · Birmingham and Coventry
Birmingham and Coventry have several small, senior, long-established bespoke software firms, and they are buried under location pages written in Nottingham, Lincoln, Northampton and Powys. Our guide surfaces the local ones and compares them honestly.
What we actually build for South East businesses
Most firms configure platforms or assemble off-the-shelf parts. We write the code for what your business actually needs.
Bespoke CRMs and business systems
Customer, sales and operations systems built around how your business actually runs, not how a packaged product assumes it does.
Warehouse and order management
Stock control, multi-warehouse inventory, pick and pack workflows and order management built to your exact process.
Workflow and process automation
Removing the manual admin, double-entry and spreadsheet juggling that quietly costs your team hours every week.
System and API integrations
Connecting your software to ERPs, accounting packages, fulfilment systems and third-party APIs so your data flows automatically.
Internal tools, dashboards and reporting
Booking tools, quoting calculators, admin portals and reporting that give you visibility and control over daily operations.
Legacy system modernisation
Rebuilding or replacing ageing systems, including older databases and COBOL, with data migrated carefully and no loss.
What our clients say
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.
