Custom software development in London
I build bespoke internal software for London businesses: the operations systems, tools and workflows that off-the-shelf products cannot quite do. Fixed price per project, built around how your team already works, and you own it at the end.
The spreadsheet is the warning sign
Most businesses that need custom software do not start by looking for it. They start with a spreadsheet that one person maintains, a shared inbox nobody quite owns, and a set of workarounds everyone knows about but nobody wrote down.
That arrangement works until it does not. It usually breaks in one of three ways: the person who understood it leaves, the volume grows past what manual checking can handle, or a mistake slips through that costs real money. By then the workaround has become the process, and no product on the market matches it, because the process grew around your particular business.
That is the point at which building something is cheaper than continuing to patch it.
What I build
- Internal operations systems. One place where your team can see the work, its status and what needs doing next, instead of five tabs and a group chat.
- Tools that fit an awkward process. The job that every product on the market almost does, and the "almost" is costing you hours a week.
- Connections between the tools you already pay for. So the same information is never typed in twice, and the two systems never disagree.
- Client and staff portals. A place for people outside your team to submit, track and check things without emailing someone to ask.
- Reporting that reflects reality. Numbers pulled straight from the work rather than assembled by hand every month.
Software I have already built and run
The most useful thing I can show you is not a list of services. It is what I have actually shipped.
- DSPOps, an operations platform for Amazon delivery partners, covering the daily running of a delivery operation, including an AI check that scans van photos and automatically flags damage. Live and in daily use at dspops.app.
- Estate Revenue Manager, a staff rota and revenue management system for high-end residential property firms, replacing the spreadsheet that used to run it.
- A case management system for a UK immigration law firm, replacing paper files and shared inboxes with one place to work. In build.
All three are the same job in different clothes: a business with a process that no product fitted, running on spreadsheets and memory, turned into a system their team actually uses.
Why work with an independent rather than an agency
London has no shortage of software agencies, and for some projects one is the right answer. For a business that needs an internal system built well, working with the person who does the work has some real advantages.
- You talk to the person building it. Nothing is lost between the meeting and the code, because it is the same person in both.
- Fixed price, not day rates. An agency's day rate rewards a project taking longer. A fixed price does not.
- No junior handover. The person who sold you the project is not passing it to whoever is free.
- I have run an operation, not just built for one. Fifteen years building software and six years running a logistics company, so I know how these systems fail in real use rather than only in theory.
The honest counterweight: an agency has more people, so it absorbs holidays, illness and sudden scale better than one person does. If your project genuinely needs a team of six, I will tell you that rather than take it on.
How a project runs
- Free workflow audit. A 30-minute call to find where the time actually goes and whether building anything is justified.
- Map the process. We go through how the work really flows, including the workarounds, because those are the requirements.
- Fixed quote. One price for the project, with the scope written down, before anything is built.
- Build in visible pieces. You see and use working parts as they land, so course corrections are cheap.
- Connect and hand over. It joins to your existing tools, your team is shown how it works, and you own the code and accounts.
Who I work with in London
Professional firms and growing businesses: legal, accountancy, property and estate agents, logistics and delivery, and other service businesses. Being in London makes it easy to sit down together while mapping the process, which is the stage where being in the same room genuinely helps. The build itself happens remotely, so I also work with businesses across the UK.
Find out what is worth building
Book a free 30-minute workflow audit. Tell me where your team loses time and I will tell you honestly what is worth building, what an existing product would do better, and roughly what each would take.

When is custom software worth it over off-the-shelf?
Custom software is worth it when the way you work is the thing that makes you good, and the available products would force you to change it. It is also worth it when your team has quietly built a system out of spreadsheets and workarounds, because that is a custom system already, just an unreliable one. If a product on the market does the job, buy the product. I will tell you when that is the case.
How much does custom software development cost in London?
London agencies commonly work on day rates that make even a modest internal tool a serious commitment. I work differently: a fixed price for the project, quoted after the free workflow audit once I have seen what is actually involved. You know the full cost before anything starts, and the risk of it taking longer than expected sits with me rather than you.
How long does a custom software project take?
A focused internal tool can be working in weeks. A full operations system for a whole team takes longer. Either way you see working pieces early and use them as they land, rather than waiting months for one big reveal that turns out to be wrong in three places.
Do we have to replace the software we already use?
No. I build around what you have. Your spreadsheets, email, calendars, accounting software and existing tools stay where they are, and the new system connects them and fills the gaps between them. Replacing everything at once is how projects fail.
What happens after the software is built?
You own it. I hand over the code and the accounts it runs on, so you are never locked in to me. If you want me to keep maintaining and extending it, I am happy to, but that should be your choice rather than something the arrangement forces on you.
