Custom software development in the UK in 2026 starts from around GBP 1,500 for a focused first version, around GBP 2,000 for a CRM or booking system, around GBP 5,000 for an ERP or advanced multi-module system, and around GBP 7,000 for a combined web app, mobile app and admin panel. These are honest starting points rather than fixed prices. Your final figure depends on features, integrations, user roles, design complexity and support, so a fixed written quote follows a free consultation.
If you have searched for a single number, you have probably found wild ranges and very little explanation. This guide gives you the real GBP figures we quote to UK businesses, explains what pushes a project up or down, and shows how a written fixed scope quote is prepared so you are never surprised by the invoice.
Why custom software is priced as a range
A custom build is priced by scope, not by a fixed menu. Two systems that both call themselves a CRM can differ by a factor of ten once you count the user roles, the reports, and the outside services each one has to connect to. A simple lead tracker for one team is a different animal from a sales platform that syncs with your accounting software, sends automated emails and serves fifty staff across three branches.
That is why any honest answer starts as a range and narrows once we understand what your business actually needs. The starting prices below are floors, not ceilings. Each number climbs as you add screens, roles and integrations.
Starting prices by project type
| Project type | Starting price | Typical timeline |
|---|---|---|
| Focused first version, one core workflow | from GBP 1,500 | 6 to 10 weeks |
| CRM or booking system | from GBP 2,000 | 6 to 10 weeks |
| ERP or advanced multi-module system | from GBP 5,000 | 3 to 5 months |
| Combined web app, mobile app and admin panel | from GBP 7,000 | 3 to 5 months |
A focused first version covers one workflow done well, for example a quoting tool, a job tracker or a customer portal. It is the fastest way to get working software in front of your team and the cheapest way to test an idea before you invest further.
A CRM or booking system adds customer records, scheduling, reminders and reporting. An ERP or advanced multi-module system ties together stock, finance, purchasing, human resources and reporting under one login, which is why it sits higher and takes longer. The top tier combines a web app, a mobile app and an admin panel, so you are effectively paying for three connected products that share one database.
What drives the cost up or down
Six factors move the number more than anything else.
Features. Every extra screen, rule and report adds build and testing time. A short, sharp feature list keeps the first version affordable.
Integrations. Connecting to accounting tools, payment providers, couriers or an existing database takes real work. One or two connections is routine. A dozen is a project in itself.
User roles. An app used by one type of person is simpler than one that must handle admins, managers, staff and customers, each with different permissions and views.
Design complexity. A clean, standard interface is quick to produce. Bespoke branding, animation and pixel level polish add hours to the build.
Data migration. Moving years of records out of spreadsheets or an old system, then cleaning and mapping that data, is often underestimated. It can be a small task or a large one depending on how tidy the source is.
Support. Ongoing maintenance, updates and hosting are a running cost. We include the first year of hosting on ownership projects and set out any later support in plain terms.
How to budget for it
Start with the outcome, not the feature list. Decide what result would justify the spend, for example fewer hours lost to manual admin, faster quotes, or the end of double entry between two systems. That target tells you how much the software is worth to your business.
Then split the work into a first version and a phase two. Many UK businesses spend near the lower end to launch a focused build, prove it earns its keep, and reinvest the savings into the next set of features. This staged approach spreads the cost and reduces risk, because you are funding phase two from results rather than hope.
Set aside a small contingency, usually ten to fifteen per cent, for the changes you will inevitably think of once real users start clicking around. Good software invites new ideas, and a little headroom keeps those improvements affordable.
Payment options that spread the cost
Not every business wants to pay one lump sum. We offer three models so the cost fits your cash flow. One time ownership transfers the source code and intellectual property to you on final payment, with the first year of hosting included. A monthly model turns the build into a predictable subscription that covers development and upkeep. Milestone based instalments split the total across agreed delivery points, so you pay as each part of the system is signed off. We confirm which model suits you in the written quote, before any code is written.
How fixed scope written quoting works
We do not hand you a vague estimate and adjust it later. After a free consultation, we write down exactly what will be built, which integrations are included, how many user roles exist and what the delivery milestones are. That document becomes your fixed price quote.
Because the scope is written and agreed, the price does not drift. If you decide to add something mid build, we price that change on its own so you always know the total before you approve it. You can review our approach to bespoke software development and see a wider breakdown of custom software development cost before you commit to anything.
Why a remote UK service changes the maths
Timeline Digital is based in Pakistan and serves UK businesses remotely. You are not paying for a central London office, and that is the main reason our starting prices sit below what a local agency typically charges for the same scope. You still get a written contract, clear milestones, regular demos and code that you own outright.
Working with a remote team also keeps timelines tight, because development continues while you sleep and demos land ready for your morning review. If you want to know more about how we operate, read about our work as a custom software development company in the UK.
