Custom Software Development in London
London is the deepest market for operational and business software in the country, and the most expensive place to commission it. We are a Kent firm 30 minutes up the line: we have built and maintained systems for London publishers and operators for years, and we do it at Gravesend rates, not City ones.
Trusted by:
The work is London-grade. The pricing does not have to be.
London has the largest concentration of operational and business-software needs in the UK: media and publishing in the centre, professional and financial services across the City, retail and e-commerce, logistics and fulfilment, agencies, healthcare-adjacent operators and tens of thousands of established mid-sized firms that quietly run on bespoke or ageing systems.
The challenge in London is rarely finding a developer. It is finding one whose rates are not loaded with the cost of a central London office, a sales team and a marketing budget, and who will still answer the phone in five years rather than having been acquired or pivoted. A lot of good systems get put off because the quotes that come back from City agencies make the business case look impossible.
We are a Kent firm 30 minutes from London Bridge. We have spent years building and maintaining software for London businesses, so the work is held to a London standard, but the overheads behind our quotes are not. We are not interested in ripping out everything that works. We fix the specific points where an old system is costing you time and money, carefully, without a disruptive overhaul of everything around them.
What a system past its best actually looks like
These patterns appear in almost every established London business we speak to. If more than one is familiar, it is worth a conversation.
A report that takes half a day to produce
The data exists. Someone extracts it, cleans it, combines it from three sources, formats it in Excel, and sends it. Every week or every month, the same half-day. A well-designed system produces it in seconds.
Data rekeyed between two packages
An order goes into the sales system. Someone types it into the accounts package. Someone checks the stock system. Three entries for one transaction, and three opportunities for the numbers to diverge.
A system nobody wants to touch
It works, roughly. Last time someone changed it, something broke. The person who built it is long gone. So it stays as it is, accumulating workarounds, until the workarounds become the system.
The process that lives in one person's head
One experienced member of staff knows how it really works. If they are off sick or leave, operations slow down noticeably. Nobody has written it down because nobody has had to until now.
Quotes from City agencies that kill the business case
The system would clearly pay for itself, but the numbers that come back from central London developers do not. So a sensible project sits on the shelf because the overheads priced into the quote, not the work, made it unaffordable.
Off-the-shelf that covers 80% and misses the 20% that matters
The gap is not a feature request. It is the specific way your business runs that no generic platform was designed for. You have been working around it since you implemented the tool.
How we work with London businesses
We start with what hurts most
No grand rebuild. We find the one or two processes causing the most friction and fix those first. You see a return before any larger work begins. Established businesses rarely need a complete overhaul. They need targeted fixes applied carefully.
We work with what you already have
Your accounts package, stock system, and the rest can usually stay. We connect bespoke software to them rather than replacing them wholesale. The goal is your systems sharing data, not a disruptive transition that takes weeks and a consultant to manage.
We are in the room when it matters
Most development runs remotely, but we are 30 minutes from central London by train. When a project benefits from walking the process with your team in person, we come to you in the City, the West End or anywhere across Greater London, without it being a production.
Software for London and Greater London
Publishing and subscription software
Circulation, subscription and reader-services platforms, fulfilment and content operations. The kind of media and publishing software we have built and maintained for London businesses such as the Telegraph and Hearst for over a decade.
Legacy system modernisation
Migrating ageing databases and legacy applications to modern, maintainable platforms without disrupting operations. Including COBOL, Access, and early-generation PHP systems running on infrastructure that needs replacing.
System integrations
Connecting the packages you already run so data flows between them without manual re-entry. Accounting software, ERP systems, stock management, e-commerce platforms. If it has an API, we can connect it.
Operational workflow tools
Custom job management, scheduling, quoting, approval and sign-off workflows. The internal software that codifies how your business operates, removing the dependency on individuals carrying the process in their heads.
Custom CRM and client management
A CRM built around how your firm actually manages accounts, pipeline or cases, not how a generic vendor assumes you do. Our CoreCRM platform as a starting point, or fully bespoke to your specification.
Reporting and data consolidation
Pulling data from multiple sources into dashboards and reports that are always current, without someone spending half a day extracting and formatting spreadsheets before anyone can see the numbers.
Long-term clients across London publishing, media, energy and operations.
Some of our longest-running relationships are with London businesses, and the work has stayed in production for years. A selection of who we have built for and kept running:
- Telegraph Media Group — publishing and subscription management software, maintained for over a decade
- Hearst Communications — circulation, subscription and reader services platforms
- CDS Global — fulfilment and publishing software in continuous production since we built it
- BPC Energy — complete bespoke business operations platform, built from scratch
- AX Paris and Motel Rocks — e-commerce and operational systems for fashion retail
- Jones Hire — warehouse picking, customer ordering and driver delivery systems
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.
We have worked with Dev Partners for 7 years and can highly recommend them for their expertise and excellent customer service.
Questions people don't always ask, but should
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.
Questions from London businesses
Almost always. We connect bespoke software to the accounts packages, stock systems and other tools you already run, so you are extending what works rather than replacing it. The goal is always that your systems share data rather than duplicate it, without a disruptive transition that disrupts operations.
You get London-calibre work without London agency overheads. We have built and maintained software for London businesses including the Telegraph, Hearst and CDS Global for years. We are 30 minutes from central London by train, so we can be in the room when a project needs it, while our rates reflect Gravesend, not the City.
Yes. Modernising ageing databases and legacy software, including COBOL, Access and early PHP systems, is something we do regularly. We migrate data carefully and keep operations running throughout, rather than requiring a cutover that brings everything down at once.
By starting with the specific pain points rather than a comprehensive system audit. 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 with care.
We are based in Gravesend, Kent, about 30 minutes from central London by train into stations such as London Bridge, St Pancras and Cannon Street. Most development work runs remotely, but for projects where being in the room matters, we are close enough to meet in the City, the West End or anywhere across Greater London without it being a production.
Since 2008, from our office in Gravesend, with the same two directors. Some of our longest-running relationships are with London publishers and operators, including software for the Telegraph maintained for over a decade. We are not a startup and we are not planning an exit. For businesses building on software they intend to run for years, that matters more than it sounds.
