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. An open-source CRM such as Krayin or EspoCRM 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.

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.

Questions people don't always ask, but should
The questions we think every business should ask a software developer, including us. The honest answers are on our custom software page.
- We've been burned by a developer before. Why would this be any different?
- How do we know the price won't balloon once the project starts?
- Are we going to be completely dependent on you forever once this is built?
- Can a company your size handle a project as complex as ours?
- We don't have a technical person internally. Will we be able to manage this?
- How long will it actually take? Every developer we've spoken to has underestimated.
- What happens if something goes wrong after the software launches?
- We've had quotes ranging from £5k to £80k for the same project. How do we know yours is realistic?
- How do we know you'll still be around in three years to support this?
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 2011, 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.

Custom software
Technologies & more
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.
