Custom Software Development UK

· UK-based · No Offshore

Frustrated with spending a fortune on different software packages, and feel like you're taking a step back?

You've got a CRM, a stock system, an accounts package, three spreadsheets and a Zapier account nobody dares touch. Every one of them cost money. Every one of them promised to save you time. And somehow your team is busier than ever.

Rob Sherwood, co-founder of Dev Partners
The short version: we replace the patchwork with one system built around how your business actually works. You own it outright, there are no licence fees, and you deal directly with me and Jason, the people who write the code. UK-based. No offshore.

When off-the-shelf stops being good enough

Most businesses start with off-the-shelf tools because they're quick to set up and cheap to run. Fair enough. We'd do the same. But every package you add is another login, another monthly bill and another place for your data to go and hide.

A couple of years later you're paying more for software than you ever have, and the business runs slower than it did when it all lived on one spreadsheet. That isn't progress. It's a step backwards with a bigger invoice.

💸

Five subscriptions, none of them joined up

Every package does its own little bit and none of them talk to each other. You pay for all of them, every month, and the licence fees only ever go one way.

🔀

Somebody's job is copying and pasting

Orders in one place, stock in another, invoices in a third. Someone exports a CSV every morning to make them agree. That's a person doing a computer's job.

📊

The spreadsheet that runs the business

One person built it. One person understands it. And that person is off on holiday next week. Good luck.

🔧

Workarounds that became "the process"

The temporary fix from two years ago is now in the training notes for every new starter. Nobody remembers why it works. Everyone's scared to change it.

🧾

Paying for 400 features, using 20

Enterprise software priced on everything it can do, most of which you'll never touch. And the one feature you actually need? That's on the next tier up.

👻

The old system nobody dares touch

Running since 2003, written in something nobody on the team knows, doing a job nobody fully understands. It works fine. Right up until the day it doesn't.

If you nodded at two or more of those, keep reading. There is a better way, and it isn't another subscription.

Stop bolting on software. Get custom software built around how you actually work.

Here's the bit the software salesmen won't tell you. You don't need another package. You need fewer of them, and the one you keep should fit your business, not the other way round.

That's what we do. We build custom software that replaces the patchwork: one place for your orders, stock, customers and reporting, working the way your business already works. Not the way a product manager in California guessed it might. If you're still weighing it up, our guide to bespoke software vs off-the-shelf is honest about when buying is the better call.

How we get you there (without a two-year project)

1
We find the one process that hurts most. Not a 60-page requirements document. A proper look at where your time and money are actually going.
2
We fix that first. You see it working, and paying for itself, before you commit to anything bigger.
3
Then we build from there, at your pace. Most of our clients have stayed with us for years, because the software grows with the business.
Rob Sherwood, co-founder of Dev Partners
“

Most of the businesses we work with aren't chasing the latest tech. They've got a system that was the right call ten years ago and now quietly costs them time every week. We start with the one process that hurts most, prove it pays for itself, and build from there. And you're talking to the people who'll actually write the code (me and Jason), not a sales team.

Rob Sherwood
Co-founder, Dev Partners

Tell us what's driving you mad. We'll tell you how to fix it.

Rob Sherwood Jason Wheeler You'll speak to Rob or Jason.
The people who write the code. Not a salesperson.

No sales pitch. No 40-page proposal.

Just a straight conversation about what's going wrong, and an honest answer about whether custom software is the right fix. Sometimes it isn't. If so, we'll tell you, and point you somewhere better.

What happens next

  1. You tell us the problem. A couple of lines is fine. No spec needed.
  2. One of us replies within a working day, usually to set up a short call.
  3. You get a straight answer: what we'd build, roughly what it'd take, or whether you're better off leaving it alone.

“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.”

Bespoke Software Development

Custom applications built around your exact requirements

When a process in your business does not fit any off-the-shelf tool, we build it. Business process software, operational platforms, back-office systems, and data management applications built from scratch around how your business actually works. You own the code, there are no licence fees, and the software does exactly what you need it to do.

Custom CRM Solutions

Built on CoreCRM, our own platform since 2011

Salesforce is a part-time job. HubSpot charges for breathing. We build custom CRM systems on CoreCRM, our own platform that has been running our business since 2011. The foundation is proven and battle-tested. You pay for the customisation to your specific workflows, not for us to rebuild solved problems from scratch.

📦

Warehouse Management Systems

Custom WMS for your specific operation

Off-the-shelf WMS platforms are designed for generic operations. If your warehouse handles fashion with size and colour variants, or steel stockholding by dimension, or catering hire with returns and condition tracking, the generic tools create as many problems as they solve. We build WMS solutions around your actual operation: stock control, pick and pack, goods in, despatch, and reporting.

🔄

Workflow & Process Automation

Cut manual work and free your team

Most businesses have significant automation opportunity sitting in plain sight: data being manually copied between systems, reports compiled by hand, notifications sent manually, status updates requiring human intervention. We identify the highest-value automation opportunities and build the systems that eliminate them. Start with our free efficiency checklist if you are not sure where to begin.

APIs and integrations
🗄️

Database Health Audit

Find out what is slowing your systems down

A slow database affects every user of every system built on top of it, and the cause is almost always structural rather than hardware. We audit your database architecture, query performance, indexing strategy, and data integrity. The output is a clear, prioritised list of what is wrong and what fixing it would involve, not a vague report full of recommendations that require a separate engagement to understand.

Legacy & COBOL Modernisation

Get off the legacy system. Properly.

We are not recommending COBOL. But if you have a business-critical system written in it that has been running for 20 years and nobody knows what it does inside, you have a risk that will not go away on its own. We extract and document the business logic, and plan and execute a migration to modern infrastructure without losing what the original system was actually doing, including the things nobody remembers it was doing.

COBOL modernisation
🔗

API & System Integrations

Make your systems talk to each other

If two systems in your business need to share data and currently do not, we build the integration. Whether it is a standard REST API connection, a file-based data exchange, a webhook-driven workflow, or a bespoke bridge between a modern platform and a legacy system, we handle the full integration rather than setting up a Zapier workflow and hoping for the best.

Technologies we use
🚀

eCommerce Migration

Move platform without losing what you have built

Platform migrations fail when they are treated as a data transfer exercise. They succeed when they account for product data structure differences, SEO equity, custom functionality that needs rebuilding, and a go-live plan that keeps you trading throughout. We have migrated businesses from Magento, Visualsoft, WooCommerce, and several legacy custom platforms to Shopify, with all of the above handled properly.

eCommerce migrations

Not sure which service fits your problem?

Describe the problem, not the solution. Most clients come to us with a description of what is going wrong rather than what they need built, and that is exactly the right starting point. We will tell you what the right answer looks like.

Problems we have already solved

If your problem looks like one of these, we have probably solved something very close to it before.

Technologies we build with

We pick the right tool for the job. Every technology below is something we use daily in production, not something listed to look comprehensive.

Laravel Development

Complex applications and bespoke platforms

Laravel is our primary choice for complex bespoke applications. It has a mature ecosystem and the flexibility to handle anything from a REST API serving a mobile app to a full back-office system processing thousands of records a day. We have used it to build ERP-style systems, custom CRMs, data pipelines, and back-office platforms for some of the UK's best-known brands.

CodeIgniter Development

Lean, fast web applications

CodeIgniter is lightweight and gets out of the way. For projects where you need a web application up and running quickly without the overhead of a full framework, it is often the right call. We also maintain and extend a large number of existing CodeIgniter systems for clients who need reliable long-term support on business-critical applications.

WordPress Development

Custom plugins, themes and back-office integrations

We write custom WordPress plugins and themes rather than configuring what already exists. When a business needs WordPress connected to a CRM, ERP, or bespoke back-office system via API, that requires code. It is where most WordPress agencies stop and where we start. Particularly strong for publishers, membership organisations, and businesses with complex editorial workflows.

Shopify Development

Shopify Select Partners · Custom builds and ERP integrations

As a Shopify Select Partner, one of a small number certified at this level in the UK, our Shopify work goes well beyond theme configuration. Custom pricing logic, ERP connections, multi-warehouse inventory management, wholesale portals, and platform migrations from Magento, Visualsoft, and WooCommerce. Clients include AX Paris, Motel Rocks, and Chi Chi London.

CoreCRM Platform

Our own CRM platform, in production since 2011

CoreCRM is the CRM we built for ourselves because nothing else did what we needed without unnecessary complexity. It has been running Dev Partners' own business since 2011. We deploy it as the foundation for client CRM projects: the infrastructure is proven and already built, your budget goes on customising it to your specific workflows rather than rebuilding solved problems from scratch.

COBOL Modernisation

Legacy rescue, not legacy recommendation

To be clear: we are not recommending COBOL. Nobody is building new systems in it and neither are we. But a significant amount of business-critical infrastructure still runs on it, and the organisations running it face a real problem: ageing infrastructure, a shrinking pool of people who understand it, and the risk of migrating away from something that has worked for 30 years. We assess, document, and migrate properly.

COBOL modernisation

All of the above sits on a foundation of MySQL and MariaDB for relational data, AWS and Cloudflare for hosting and infrastructure, and React and JavaScript for frontend interfaces where needed. The full picture is on our technologies page.

Four steps from problem to working software

The same process whether you are building a small internal tool or a complex multi-system integration.

1

Systems Analysis

We audit what you have, how it is used, where it breaks down, and what good actually looks like. No proposals before we understand the problem. If the answer is not custom software, we say so at this stage.

2

Design

We design a solution around your workflows rather than around what is easiest to build. You see exactly what we are planning before development starts and sign off on it. No surprises mid-build.

3

Build

Development is iterative and visible. You see progress as it happens, test against real scenarios, and steer the project throughout. Every line of code is written by our UK-based team. No subcontracting.

4

Launch and Beyond

We handle rollout, train your team in plain English, and stay involved after go-live. Your business will change. Most of our clients have ongoing development retainers because their software changes with it.

Exploring Potential Software Partners?

If you're building a shortlist, we've put together an independent guide to the top custom software development companies in the UK - including how they compare on discovery process, UK team presence, integration capability, and long-term support.

We're on the list. We'll let the comparison speak for itself.

What makes us different

There are hundreds of software development companies in the UK. These are the reasons clients come to us and stay with us.

👥

You talk to the people building it

Rob and Jason, the founders of Dev Partners, are active on every project. When you call, you speak to a developer who knows your system. There is no account management layer between you and the code.

🇬🇧

UK-based, fully in-house

Every developer is UK-based and in-house. We have never outsourced development and we never will. This is not a marketing position. It is how we maintain quality and responsiveness.

🔑

You own everything

The code we write for you is yours. No licence agreements, no vendor lock-in, no requirement to keep paying us to access your own system. You own it outright from day one.

🗓️

Long-term partners, not project shops

Most of our clients have been with us for years. We are still here when things change, when the business grows, when the original system needs extending. That is the relationship most clients actually want.

🎯

We tell you if we are not the right fit

If your requirement is better served by a different solution or a different company, we say so. We would rather give you the honest answer than take your money and deliver something that does not fit.

⚡

Proper problem-solving, not template-filling

We do not build the same system over and over with different logos. Every project starts with understanding your specific problem. The solution comes from that, not from what we happened to build last time.

The kinds of businesses that commission bespoke software from us

We work with businesses across a wide range of sectors. The common thread is not industry. It is that they need software built around how they specifically operate.

Find out what you are actually running

If the original developer has gone, the documentation does not match the code, and nobody is confident enough to change anything, that is the normal starting point rather than an unusual one. Our Legacy Application Audit is a written report within five working days covering security, database structure, scalability and maintainability, and a straight verdict on whether to stabilise, upgrade or rebuild. Give us a call and we will talk it over first. We do not push rewrites you do not need.

What our clients say

19 clients. A few of their words.

“

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.

Custom software development: your questions answered

The things people ask us most, including the awkward ones worth asking any developer you're considering. Straight answers, no sales spin.

It's software built for one business: yours. Instead of buying a package designed for thousands of companies and bending your processes to fit it, you get a system built around how your team already works. You own the code, you don't pay licence fees, and it does the things you need rather than 400 things you don't.

It depends entirely on what you need, and anyone who gives you a number before they understand the problem is guessing. We scope it properly first, then give you a fixed price before any work starts. No licence fees, no surprise invoice at the end. The quickest way to get a real answer is to tell us the problem.

Not always. If an off-the-shelf package does 90% of what you need and your team is happy with it, keep it. Custom software earns its keep when you're paying for several tools that don't talk to each other, running the business on spreadsheets, or bending your processes to fit someone else's product. Our guide to bespoke software vs off-the-shelf goes into more detail.

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.

Got a software problem? Talk to Rob and Jason.

Describe what is going wrong. We will tell you what the right solution looks like.

Most conversations start with something like: "we have a process that is costing us a lot of time and we have outgrown the tools we started with." That is exactly the right starting point. We have heard most versions of that problem and solved most of them.

What a good first conversation covers:

  • The process that is causing the most friction right now
  • What systems are involved and how data currently flows between them
  • What you have already tried and why it did not solve it
  • Scale: how many users, how much data, how much transaction volume
  • What good looks like if the problem is solved
