Bespoke software for the businesses big software companies won't touch

For owners and managing directors of growing UK businesses. You know exactly which problem is costing you time and money. Traditional software companies price for corporates, so you make do with spreadsheets and tools that never quite fit. AI has moved that line.

01 · Is this you?

You sit below the line where software companies step in.

If two or more of these sound familiar, you're exactly who bespoke software was never priced for, until now.

  • Your business has outgrown spreadsheets, but a big software project feels out of reach
  • Your team re-keys the same information into several systems every week
  • You pay per-seat licences for tools you only half use
  • You asked for a quote and never heard back, or got a number that made no sense for your size
  • You know AI could help, but not where to start
02 · The line

Why most SMEs have been priced out.

Traditional software companies bill by the day, and their overheads are built for corporate clients. A modest business system quickly runs to tens of thousands of pounds, so they focus on bigger projects. The chart shows where a typical SME budget sits against the cost of a traditional build.

03 · The market

What software actually costs to build.

UK day rates (£) Contractor £525 Agency £400£900 £150£1,000

Contractor: median and middle half (£428–£575), ITJobsWatch, 6 months to Oct 2026. Agency: Elastic Mint.

Senior vendor rates ($ an hour) Asia $31–41 Europe $64–76 $0$100

04 · A worked example

One project, three ways to build it.

An order and quoting tool that connects to existing accounts software, needing 60 engineer-days built the traditional way. Here's what it costs over three years, including upkeep.

Three-year cost of ownership (£) UK agency £54,900 AI-built, human-directed ~£16,500 Build Upkeep, 3 years (17.5% a year) Offshore: about $16,800 to build at senior Asian vendor rates, before your extra management time, rework and delay.

Agency at £600 a day (mid-point of Elastic Mint's £400–£900 range). Offshore at $280 a day (Accelerance, senior, Asia). AI-built cost reflects our typical pricing of around 30% of UK agency cost. Upkeep at the mid-point of Elastic Mint's 15–20%. Illustrative; your project will differ.

05 · Hidden costs

What never appears on the quote.

Management timeSomeone in your business writes specs, answers questions and tests every delivery.
ReworkMisread requirements get fixed at your expense, in time if not money.
DelayEvery week a system isn't live is another week of the old cost.
Data and contractsPersonal data leaving the UK needs UK GDPR safeguards; disputes may sit under overseas law.
Upkeep15 to 20% of build cost, every year, for as long as you run it.
06 · What AI changes

Directed by an experienced engineer, AI builds software better than humans working alone.

That's our view, from building with it every day. AI writes the code, the tests and the documentation together, follows the same standards on every line, and never gets tired or cuts corners at 5pm. The human sets the direction, the architecture and the rules, then reviews and signs off every release. Better software, in far fewer billable days: that's what finally puts it within reach of SMEs.

~30% of expected cost
  • The human sets the goal, the architecture and the rules
  • AI drafts the code, tests and documentation
  • A senior engineer reviews, hardens and signs off every release
  • You own the result, with a fixed price and a payment plan
07 · How to choose

Five questions to ask any software partner.

  • Do you want projects my size, at a fixed price?
  • Who reviews the code and signs off each release?
  • Where will my data live, and under which law is the contract?
  • What will upkeep cost each year?
  • Who owns the code when you're done?
