How much does bespoke software cost for a UK small business?
Published UK guides put a typical small-business bespoke build at £5,000 to £50,000, from about £2,000 for a simple internal tool to £8,000 to £37,500 for a CRM, and suppliers disagree widely. Budget a further 15 to 20% of the build cost each year to run it. A written fixed quote is the only price that counts.
Nobody can price bespoke software without knowing the work, so any single number on the internet is a guess. What you can do is see what UK suppliers publish, understand why their figures differ several times over, add the running costs most quotes leave out, and check whether an off-the-shelf tool would do the job for less. This guide does those four things for trades and service businesses weighing up a CRM, a quoting tool, a booking system or a job app.
A disclosure before you read on: Scalepoint builds bespoke software for trades and service businesses. We do not publish a price list for it. Each build is quoted as a fixed one-off build fee before work starts, then ongoing management from go-live. Every range below is another supplier's published figure, not ours, and we mark which is which.
What UK suppliers publish
We read five UK cost guides published between January and September 2026. They are written by suppliers, so each reflects how that supplier works, and they are not like-for-like. The useful result is the spread.
| Publisher | Simple tool or small build | CRM or mid-size system | What it says it covers |
|---|---|---|---|
| Original Objective | £2,000 to £15,000 (simple internal tool); £5,000 to £25,000 (customer portal) | £15,000 to £37,500 (CRM with custom workflows and reporting) | Timelines of 8 to 20 weeks; AI-assisted development said to cut costs 20 to 40% |
| Elastic Mint | £5,000 to £50,000 for most SME builds | Inside the same range | Day rates of £400 to £900; budget 15 to 20% of the build a year afterwards |
| DataVolve | £1,500 to £5,000 (internal tool that replaces a spreadsheet) | £8,000 to £24,000 (custom CRM with automation and reporting) | A small senior team; London onshore agencies often quote two to four times more |
| Make IT Simple | £15,000 to £50,000 (small or simple) | £50,000 to £150,000 (mid-range) | Maintenance 15 to 20% of the build a year |
| 16i | £25,000 to £50,000 (small but genuinely bespoke product) | £50,000 to £150,000 (established custom platform) | Working ranges, not fixed market rates |
The same kind of job is priced from £1,500 to £50,000 depending on who you ask, and the cheapest published CRM figure (£8,000) sits below the lowest figure another supplier gives for any system at all (£15,000). That is not one of them being wrong. They are quoting different things, built by different teams, at different day rates.
Why quotes for the same software differ so much
Almost every quote is a day rate multiplied by a number of days. Scope sets the days and the team sets the rate. DataVolve's 2026 rate table shows how far apart the rates start:
| Who builds it | Typical day rate |
|---|---|
| London agency or consultancy | £800 to £1,500+ |
| Regional UK agency | £500 to £900 |
| UK freelance contractor | £400 to £700 |
Elastic Mint lists the five things that add days, and they are the questions to answer before you ask anyone for a price:
- User roles. One kind of user is cheap. Each extra role (admin, manager, customer, approver) adds screens, permissions and testing.
- Integrations. Every system you connect (accounts software, payments, maps, single sign-on) is a small project of its own.
- Data complexity. Simple records are quick. Relationships between records, reporting and data that must stay accurate cost more.
- Migration. Replacing a system people rely on means moving live data without stopping the business.
- Platforms. A web app is one build. Adding iOS and Android adds more to build and test.
The cost after launch
The build price is not the whole bill. Elastic Mint and Make IT Simple both put yearly running costs (hosting, maintenance, updates and third-party fees) at 15 to 20% of the build cost. On a £10,000 build that is £1,500 to £2,000 a year. Ask any supplier what the ongoing fee covers, who fixes a fault, and what it costs to add a feature in year two. Check VAT too: DataVolve notes that many UK quotes are ex VAT, and the standard rate is 20% (GOV.UK). If you are VAT-registered you can usually reclaim it, but the cash leaves your account first.
Trade quoting software: when off-the-shelf costs less
For straightforward line-item quotes, a ready-made tool is almost always cheaper than a build. Tradify publishes £34 (Lite), £37 (Pro) or £44 (Plus) per user per month, month to month with no contract (tradifyhq.com/uk/pricing, read 1 November 2026). VioTrade publishes £20 a month plus £10 a month per extra team member (viotrade.co.uk/pricing, read 1 November 2026). Here is the arithmetic for a three-person team against a bespoke build. The bespoke figures are illustrative: the build price is the bottom of DataVolve's custom CRM range, and the running cost is the 15% low end of the 15 to 20% above.
| Option | Year one | Five years |
|---|---|---|
| Tradify Pro, 3 users (£37 each a month) | £1,332 | £6,660 |
| VioTrade, 3 users (£20 plus £10 for each of two extra members) | £480 | £2,400 |
| Bespoke build at £8,000, plus 15% a year to run (£1,200) | £9,200 | £14,000 |
On software cost alone, bespoke loses for a team that prices from a standard price book. It wins when the software changes how fast or how accurately you quote. The test is simple: hours saved a week, times what an hour is worth to you, times about 48 working weeks. As an illustration only, five hours a week at £30 an hour is £7,200 a year. If that is realistic for your business, a build can pay back. If you cannot name the hours, buy the off-the-shelf tool.
When bespoke is worth it
- The real price lives in a spreadsheet: area times pitch, rooms times frequency, hours times crew, with a minimum and a margin on top. A line-item tool never sees the working.
- Two people give two different prices for the same job.
- Supplier prices change and your price lists are updated by hand in several places.
- Only the owner can price the hard jobs, so quotes wait for evenings and weekends.
- You pay for seats and features nobody uses to get the one you need, or you copy the same details between two or three tools every day.
If none of those fits, start with the off-the-shelf tool and revisit in a year. If two or more do, read bespoke quoting software, bespoke CRM or bespoke job management to see what a build for your kind of business involves.
How to read a bespoke software quote
- Is the price fixed, or a day rate with an estimate? Ask for a fixed price in writing for a defined scope.
- Does it include discovery, and is that priced separately? Discovery decides what gets built first.
- Which integrations are in scope, and which systems will it connect to on day one?
- Who owns the code, the data and the hosting account? You should be able to leave with all three.
- What does the ongoing fee cover, and what does a new feature cost in year two?
- Is the quote ex VAT, and what is the payment schedule?
Sources & method
Bespoke software cost ranges come from five UK supplier cost guides read on 1 November 2026: Original Objective (originalobjective.com/blog/bespoke-software-development-for-uk-businesses, 3 April 2026), Elastic Mint (elasticmint.com/blog/how-much-does-bespoke-software-cost-uk, 13 July 2026), DataVolve (datavolve.co/insights/custom-software-development-cost-uk, 24 September 2026), Make IT Simple (makeitsimple.co.uk/blog/how-much-does-custom-software-development-cost, 14 May 2026) and 16i (16i.co.uk/insights/custom-software-development-cost-2026, 26 January 2026). Each is a supplier's own view, not a survey, and we have not verified them. The Tradify and VioTrade prices come from tradifyhq.com/uk/pricing and viotrade.co.uk/pricing, read on 1 November 2026. The 20% VAT rate is the GOV.UK standard rate (gov.uk/vat-rates). The comparison table and the hours-saved example are Scalepoint's own illustrative arithmetic, not data. Scalepoint's bespoke software is quoted as a fixed one-off build fee before work starts, then ongoing management from go-live, as stated on scalepointdigital.co.uk/bespoke-software. Suppliers change their prices, so confirm current figures before you decide.
In summary
Published UK guides put a small-business bespoke build at £5,000 to £50,000, with a CRM from £8,000 to £37,500 depending on the supplier, plus 15 to 20% of the build a year to run it. Off-the-shelf tools like Tradify (£34 to £44 per user a month) and VioTrade (£20 a month) cost less on paper, so bespoke only pays when it saves real hours or prices work the standard tools cannot.
