Custom Software Development · Tonbridge · TN9 · West Kent
Growing Tonbridge businesses tend to hit the same wall. The spreadsheet that held everything together stops scaling. Three apps that do not talk to each other. A process that only works because one person remembers all the exceptions. We build the software that takes that weight off.
Trusted by:





Tonbridge is full of ambitious small and mid-sized businesses. Well-connected, close to Tunbridge Wells and the M25, and with the kind of owners who think bigger than the town's size suggests. The pattern we see most often is a company that has grown steadily and is now being held back by the very tools that got it this far.
A spreadsheet doing the job of a database. Three apps that each do their own thing and require someone to manually copy data between them. A pricing model, a booking process or a fulfilment workflow that is too specific to your business for any off-the-shelf tool to model correctly. The process that only runs smoothly because one experienced person remembers all the edge cases.
Bespoke software fixes this by being built around how your business actually works, not the other way around. The point is not features. It is removing the friction, the double entry and the manual chasing that is eating your team's time and holding the growth back.
These are the patterns we see in almost every growing Tonbridge business we speak to. The more familiar these look, the more worth a conversation this is.
It started as a quick tracker and grew into something the whole operation depends on. It is not really a spreadsheet anymore. It is a database with no data structure, no access controls, and a single point of failure.
You have a CRM, a job management tool, and an accounts package. They each do their job. Moving data between them is somebody's actual job, for an hour every day, with a high chance of error.
Every new client or order creates more manual work rather than less. The operations cost per unit is going up as the business grows, when it should be going down.
One person knows how it really works. When they are on holiday, things slow down. When they eventually leave, there will be a real problem. Nobody has written the process down because it has never had to be.
The numbers that matter live inside a system nobody can easily extract them from. The monthly report takes someone most of a day. Decisions get made on instinct because the data is not visible in real time.
You have looked. The closest tool covers 80% and falls apart on the 20% that is specific to your business. You have been working around that gap since you implemented it.
A spreadsheet that has become load-bearing, rebuilt as a proper multi-user system with a real data structure, access controls, and an audit trail. The same job, done reliably at any scale.
Connecting the apps you already use so data flows automatically rather than being moved by hand. CRM to accounts. Job management to invoicing. Stock to e-commerce. If it has an API, we can connect it.
The manual steps that could trigger automatically: notifications, status updates, handoffs between departments, document generation. Removing the human from the loop for the parts where human judgement is not actually required.
A CRM built around your sales process, account management model, or service delivery workflow. Not a generic pipeline with fields renamed to approximate what you need. Something that fits from the start.
Real-time visibility into the numbers that matter, without someone extracting and formatting them first. Dashboards that pull from your live systems and always show the current picture.
A secure login area where your clients can place orders, access documents, track jobs, or submit information. Reducing the inbound calls and emails that are taking up time your team should spend elsewhere.
We work with businesses at every stage from ambitious SMEs removing their first operational bottleneck to national names with complex systems requirements. The quality of the work does not change with the size of the client.
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.
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.
Then start with a conversation rather than a commitment. We will tell you honestly if an off-the-shelf tool would do the job, and we regularly turn people away when bespoke is not the right answer. The first call is free and there is no obligation to proceed. If the answer is a tool that already exists, we will point you at it.
A focused first build typically takes eight to fourteen weeks from signed-off specification to live. We tackle the highest-value piece first and grow from there rather than trying to do everything at once. We scope carefully before any work starts and give a fixed price, so you know what you are committing to before any work begins.
Our in-house team in Kent. No offshore, no subcontracting. You deal with Rob or Jason directly throughout, and the people who scope your project are the people who build it. There is no account management layer between you and the developers.
Usually yes. Growing businesses typically have several tools that work individually but do not share data. Connecting them is one of the most common things we do and often one of the quickest wins. If a tool has an API, we can connect to it. Many of the integrations we build pay back within months in saved admin time.
Yes. The source code and your data are yours outright from day one. No licence fees, no ongoing dependency on us to keep it running. If you want to take the code elsewhere at any point, it is yours to do so. We are confident enough in the quality of the work and the relationship that we do not need to lock anyone in.
We are based in Gravesend, about 25 miles away via the A227 or A21. A straightforward drive and close enough to meet when a project benefits from it. For a growing business where walking a process with your team is worth doing, we are genuinely nearby.
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.
Describe the process that is slowing you down. We will give you a straight view on whether bespoke software is the right answer and what it would involve. If it is not worth it, we will tell you that.
