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 finance agent can keep a fixed asset register by spotting purchases above your capitalisation threshold, recording each asset's cost, date and useful life, and posting depreciation every month. Deciding whether an item is an asset, what life it has and which tax allowances apply are judgements for a person and their accountant.
What a fixed asset register is for
A fixed asset is something the business buys to use over more than one year: laptops, vehicles, machinery, office fit-out, sometimes software. Rather than treating the whole cost as an expense in the month of purchase, accounts usually spread it over the years the asset is used, through depreciation. Standards such as IAS 16 set out this approach for property, plant and equipment.
The register is the list behind that figure on the balance sheet. For each asset it records what it is, when it was bought, what it cost, how long it is expected to last, how much has been depreciated and where it is. Small businesses often skip it, and the result is a balance sheet nobody can explain, laptops still on the books years after they were recycled, and missed questions at year end.
What the agent can take on
- Spotting candidates. Any purchase above your capitalisation threshold, and coded to equipment, vehicles or similar, is flagged as a possible asset.
- Creating the record. From the invoice, the agent records the supplier, description, cost excluding recoverable tax, date and, if you supply it, serial number and location.
- Applying your policy. It assigns the useful life and depreciation method set in your policy for that category.
- Monthly depreciation. At each close it posts the month's charge and reconciles the register to the balance sheet.
- Disposals. When an asset is sold or scrapped, it calculates the gain or loss and removes the asset, once a person confirms the disposal.
A simple policy the agent can follow
| Category | Example useful life | Method |
|---|---|---|
| Laptops and phones | 3 years | Straight line |
| Office furniture | 5 years | Straight line |
| Vehicles | 4 to 5 years | Straight line or reducing balance |
| Machinery | 5 to 10 years | Straight line |
| Leasehold improvements | Shorter of lease term or useful life | Straight line |
A capitalisation threshold, for example any single item over £500, keeps the register manageable. Items below it are expensed straight away. The agent applies the threshold consistently, which is more than most manual registers achieve.
Accounting depreciation is not tax relief
A common confusion is that depreciation in the accounts is the same as tax relief. In many countries it is not. In the UK, GOV.UK describes capital allowances as the tax relief that lets businesses deduct some or all of the value of equipment, machinery and business vehicles from profits, for example through the annual investment allowance of up to £1 million on certain plant and machinery. That relief is worked out separately from the depreciation in your accounts, and GOV.UK notes that sole traders and partnerships using cash basis can generally claim capital allowances only on business cars. In the US, the IRS sets out tax depreciation rules in Publication 946, which can differ from the depreciation in your management accounts. Canada and Nigeria have their own capital allowance systems.
An agent can keep the information both calculations need, such as cost, date, category and disposal proceeds, and present it to your accountant. Which allowances to claim and when is tax work for a qualified adviser, and choices made there can affect cash flow significantly.
A worked example
Example only. A design studio buys four laptops for £1,250 each in April, excluding VAT, and a £320 monitor. Its policy capitalises items over £500 and depreciates laptops over three years.
- The agent flags the laptop invoice as a candidate asset and expenses the monitor, which is below the threshold.
- It creates four register entries of £1,250, each with a serial number from the invoice.
- From April it posts depreciation of about £139 a month (£5,000 over 36 months).
- In September one laptop is stolen. The owner confirms the loss; the agent removes it, posts the remaining net book value as a loss and links the insurance claim.
At year end, the accountant receives the register with additions, disposals and depreciation reconciled, rather than a list of invoices to sort through.
Where it needs a person
- Whether a mixed invoice, such as a fit-out with furniture and labour, is one asset or several.
- Whether a repair is maintenance or an improvement that should be capitalised.
- Useful lives for unusual assets.
- Impairment, when an asset is worth much less than its book value.
- Every tax election and allowance claim.
A yearly physical check is also worth keeping. The agent can produce a list of every asset by location or holder and ask each person to confirm what they still have; anything not found is brought to the owner as a possible disposal or loss.
Good registers start with a good chart of accounts, with separate cost and depreciation accounts for each asset category.
Where Pryme fits
On a Pryme Business account, the Finance agent runs the books and the month-end close, posting recurring entries such as depreciation inside its mandate, with every figure traced to a journal and its source. Asset decisions and tax treatment come to you and your accountant. For how AI fits into finance more widely, see AI agents for business finance.
Questions people ask
What is a capitalisation threshold?
The minimum cost at which a purchase is treated as a fixed asset rather than an expense. It is a policy choice your accountant should agree.
Is depreciation tax deductible?
Often not directly. In the UK, tax relief usually comes through capital allowances instead, and the US has separate tax depreciation rules. Ask an adviser.
Can the agent track where assets are?
It can record a location or holder for each asset and remind you to confirm them, for example with a yearly check.
What happens when an asset is sold?
The agent removes it from the register, compares the proceeds with its net book value and posts the gain or loss, once a person confirms the sale.
