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.
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
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.
