    How much does custom software development cost in 2026?

    Why custom software quotes vary so much

    Two quotes for the "same" system can differ tenfold. That is because the cost depends less on the idea and more on a handful of factors that are easy to miss.

    • How many types of record and screens the system needs.
    • How many people use it and what each role is allowed to see.
    • Connections to other tools, such as accounting, payments or email.
    • Whether it needs to work offline, on phones, or in several languages.
    • Who pays for hosting, security, updates and fixes after launch.

    Our approach: fixed plans, everything included

    Instead of an open-ended quote, Ceejay offers four fixed plans. Each has a one-off setup fee to build your system and a monthly fee that covers hosting, backups, security, updates, support and ongoing changes.

    • Starter: £2,995 setup + £250 a month, for up to 25 users.
    • Business: £4,795 setup + £380 a month, for larger teams and more workflows.
    • AI: £7,295 setup + £950 a month, with AI features built into your system.
    • Enterprise: £14,995 setup + £1,750 a month, for complex, multi-team systems.
    • Prices are also available in EUR, USD, CAD, AUD and NZD on our pricing page.

    Plugins, licences and developer hours add up. This does not.

    How to budget for custom software

    Start with what the problem costs you now: hours spent re-typing, chasing and fixing mistakes, plus what you pay for the tools you would replace. If a system saves two staff a few hours a week each, that alone often covers the monthly fee. Then pick the smallest plan that covers your first version — you can grow into a bigger one later.

    Why our prices are lower than a traditional agency

    Ceejay Intelligence builds with modern tools that cut development time dramatically, and we focus on business systems we know well: records, workflows, portals, dashboards and reports. You still get a custom system built around your business, delivered finished and managed for you.
