AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
An AI agent can check every pay period that each worker's pay, divided by the hours they actually worked, meets the minimum wage rate for their age, and flag birthdays, apprenticeship anniversaries and April rate changes before payroll runs. It cannot decide whether someone is a worker, which hours count as working time in unclear cases, or how to put right an underpayment; those need a person and often advice.
The rates and who they apply to
The minimum wage depends on age and, for apprentices, on the stage of the apprenticeship. From 1 April 2026 the rates are:
| Worker | Hourly rate from April 2026 | April 2025 to March 2026 |
|---|---|---|
| 21 and over (National Living Wage) | £12.71 | £12.21 |
| 18 to 20 | £10.85 | £10.00 |
| Under 18 | £8.00 | £7.55 |
| Apprentice | £8.00 | £7.55 |
Workers must be above school leaving age to be entitled to the National Minimum Wage, and the National Living Wage applies from 21. The apprentice rate applies to apprentices under 19, and to those aged 19 or over in the first year of their apprenticeship; after that first year, an apprentice aged 19 or over is due the rate for their age. Rates are set each year, so the table needs updating every April.
Why compliant employers still underpay
Few small employers set out to pay below the minimum. Underpayments usually come from detail. The headline hourly rate is fine, but something else pulls the effective rate down.
- A worker's birthday moves them into a higher band and nobody changes the rate.
- An apprentice passes the first anniversary of their apprenticeship and is still on the apprentice rate.
- A salaried worker's hours creep up, so salary divided by hours falls below the rate.
- Time that counts as work, such as required training, opening up or cashing up, is not paid.
- Deductions or payments for things the worker needs for the job, such as a uniform, reduce pay for minimum wage purposes.
- The April increase is applied late, or only to some staff.
GOV.UK publishes guidance on how the minimum wage applies to different types of work and a calculator for checking pay. When the rules are unclear for a particular job, such as sleep-in shifts or travel between appointments, that guidance or an adviser is the place to go, not an agent's best guess.
What an agent can check each pay period
- Hold each worker's date of birth, start date, apprenticeship start date and pay basis.
- Before payroll, take the hours from rotas, timesheets or clocking records, including recorded time for training and closing duties.
- Divide pay that counts for minimum wage purposes by those hours and compare with the right rate for the worker's age on the pay period's dates.
- Flag any worker below the rate, or within a margin you set, with the working shown.
- Diary each birthday, apprenticeship anniversary and 1 April in advance, with the new rate.
- Keep the check and the records it used, so you can show how pay was worked out.
Each of these is a calculation on records you already hold. The agent's value is doing it every period, for every worker, rather than once a year when someone remembers.
A worked example: a salaried supervisor in a café
This is an illustrative example using April 2026 rates. A café in Leicester pays a 24-year-old supervisor £24,000 a year for a contracted 37.5 hours a week. On paper that is about £12.31 an hour (£24,000 ÷ 52 ÷ 37.5), which was above the old £12.21 rate but is below the new £12.71.
The agent runs its check before the April payroll and flags it with the working. It also notices that rotas show the supervisor regularly staying 30 minutes after closing to cash up, which takes recorded hours to 40 a week and the effective rate to about £11.54. The owner decides to raise the salary and to add closing time to the paid rota. The agent records the decision and checks again each month.
What stays with a person
- Deciding whether someone is an employee, a worker or self-employed.
- Judging whether unclear time, such as on-call periods, counts as working time.
- Working out and paying arrears if an underpayment is found, and how to explain it to the worker.
- Setting pay above the minimum, and handling any change to contracts.
- Any contact from HMRC about minimum wage enforcement.
Records matter here. Employers must keep records that show they paid at least the minimum wage, and HMRC can require arrears and penalties where workers were underpaid. An agent that keeps each period's check alongside the hours it used makes those records easier to produce, but it does not replace getting the rules right.
Where Pryme fits
The Pryme Compliance agent keeps obligations such as each April rate change and each worker's birthday on one register with its own date, and refuses to answer where its policy set is silent. Pryme payroll runs from the business account, with the Finance agent preparing each run for a person to approve.

Questions people ask
What is the minimum wage for a 20-year-old from April 2026?
£10.85 an hour. The National Living Wage of £12.71 applies from age 21.
When does an apprentice move off the apprentice rate?
An apprentice aged 19 or over moves to the rate for their age after the first year of the apprenticeship. Apprentices under 19 stay on the apprentice rate.
Can a salaried worker be paid below the minimum wage?
No. Divide pay by the hours actually worked; if the result is below the rate for their age, they are underpaid even if the salary looks reasonable.
Can an AI agent decide what counts as working time?
It can apply rules you set, but unclear cases such as on-call time need a person, using GOV.UK guidance or advice.
