The verdict in three sentences
For a London certification body scheduling 35 to 70 auditors who travel across the UK, custom audit and certificate management software sits at a 2026 market ballpark of £50,000 to £170,000, excluding VAT. The line that swings the quote most is auditor scheduling with competence and impartiality checks, because that is what your UKAS assessor will look at first. Insist on an itemised quote with days of effort per line and recurring costs shown separately, typically 15 to 20 % of the build cost per year.
The itemised quote, line by line
The structure below reflects a typical 2026 quote from a UK development studio, assuming day rates in the £600 to £950 range (2026 market ballpark) and a body certifying management systems such as ISO 9001 and ISO 27001.
| Line item | Days of effort | 2026 market ballpark (GBP, ex VAT) |
|---|---|---|
| Discovery workshops with the technical manager and schedulers | 6 to 12 days | 4,000 to 10,000 |
| Client, site, scope and certification cycle records | 10 to 20 days | 7,000 to 17,000 |
| Auditor scheduling: competence codes, impartiality, travel time across the UK | 20 to 55 days | 14,000 to 48,000 |
| Audit planning, report templates, technical review and certification decision | 12 to 28 days | 9,000 to 24,000 |
| Nonconformity and corrective action tracking | 10 to 30 days | 8,000 to 25,000 |
| Certificate issue, suspension, withdrawal and online verification register | 8 to 18 days | 5,000 to 15,000 |
| Client portal and migration from spreadsheets | 8 to 25 days | 6,000 to 20,000 |
| Testing, penetration test, go-live | 6 to 15 days | 4,000 to 11,000 |
Indicative total: £57,000 to £170,000. A scheduling-first build lands near the bottom; a full platform with client portal, public register and accounting integration lands near the top.
What UKAS expectations add to the scope
Accreditation against ISO/IEC 17021-1 means you must evidence auditor competence, impartiality and the basis of every certification decision. In software terms, that means an audit trail on every scheduling and decision step, competence records linked to technical areas, and reports that cannot be silently edited after sign-off. Budget for these from day one: retrofitting an audit trail costs more than building it in.
Recurring costs over three years
| Recurring item | Basis | 2026 market ballpark (GBP per year) |
|---|---|---|
| Maintenance and minor enhancements | 15 to 20 % of build | 8,500 to 34,000 |
| UK hosting, backups, monitoring | document volume | 2,000 to 8,000 |
| E-signature for reports and certificates | volume of envelopes | 1,200 to 5,000 |
| Annual penetration test and Cyber Essentials Plus support | scope | 2,500 to 8,000 |
| User support for schedulers and auditors | annual retainer | 1,800 to 7,000 |
A £100,000 build therefore costs roughly £165,000 to £245,000 over three years. Compare that figure with the salary cost of manual scheduling, not with the build price alone.
A nearshore option: Kolonell's prices
Kolonell's prices for custom applications are public: medium application 6,100 to 10,670 EUR (4,000,000 to 7,000,000 FCFA) and complex application 10,670 to 22,870 EUR and more (7,000,000 to 15,000,000 FCFA and more). Audit scheduling with nonconformities and certificates falls in the complex category. Monthly maintenance runs from 53 EUR (35,000 FCFA) for Basic to 183 EUR (120,000 FCFA) for Premium. Put it side by side with London quotes on an identical scope document.

Illustrative example: Priya, operations director of a London certification body, manages 650 clients and 1,000 audits a year with 50 auditors. Three schedulers spend about half their week juggling spreadsheets, train times and auditor availability, which is 1.5 FTE at £42,000 loaded cost, or £63,000 a year.
With a £115,000 build and £22,000 a year in recurring costs, and if automated scheduling frees 65 % of that time (about £41,000), the net annual saving is around £19,000. Payback on scheduling alone is about six years, but the real gain is capacity: absorbing 250 extra audits without hiring a fourth scheduler brings payback under three years.
FAQ
How much does audit management software cost a UK certification body in 2026?
The 2026 market ballpark for a custom build is £50,000 to £170,000 ex VAT. Scheduling complexity and integrations drive most of the spread.
Can the nonconformity module be built on its own?
Yes, usually for £8,000 to £25,000. It must share the client and audit records, otherwise your team will key the same data twice.
Do we need an online certificate verification register?
It costs around £5,000 to £15,000 including suspension and withdrawal logic. It cuts verification calls and reassures your clients' customers.
How long does delivery take?
Plan 4 to 8 months for 80 to 200 days of effort. Shipping scheduling first gives your team relief from month three or four.
What should we budget for maintenance?
On the UK market, 15 to 20 % of the build per year. Kolonell's maintenance plans run from 53 EUR to 183 EUR per month depending on the tier.
