Custom Software Development in Sevenoaks

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.
