How is a full finance function affordable for a firm of this size?

A full time finance director plus a small team usually starts north of £150k a year, which is why most firms turning over £500k to £5m do not have one. AI Finance Partners uses modern tools to take the mechanical work off the desk, so qualified accountants can give the firm proper attention at a fraction of that cost. Our accountants sign every output.

What is the difference between a bookkeeper, an accountant and a management accountant?

A bookkeeper records what happened, which is control. An accountant files what happened, which is statutory. A management accountant decides what happens next, which is enablement. The first two are essential and both look backwards by design. The middle is where decisions are made and most firms have nobody there.

Who does AI Finance Partners work with?

Owner managed professional services firms turning over £500k to £5m across the South East of England. Law firms, accountancy and finance practices, consultancies and agencies, architects, surveyors and recruiters.

Do we have to move everything, or can we keep our existing accountant?

Both work. Many firms keep their existing accountant for Statutory and Control and engage AI Finance Partners on Enablement alone, which is the monthly management accounts, profitability and forecasting layer.

02 · This is the problem

The decision is now.
The data is not.

Your landlord raises the office rent. A senior fee earner asks what you can pay to keep them. A good client wants thirty more days to settle. You do not have the numbers in front of you to answer. So you guess, or you say no. By the time the bookkeeper sends the file next Tuesday, the decision has already been made.

The owner is also the finance department.

You built a firm to practise your profession, not to chase work in progress, run payroll, model the drawings and be the finance director, the credit controller and the analyst.

Month end takes weeks, not days. Cash is a bank balance rather than a lock up view. Two providers, both looking backwards.

03 · How we solve it

One firm. The whole finance function,
from the filing to the forecast.

What you have to, what you should, what you would like, and the specialist tax advice for when it matters. Take the lot as a complete finance function for your firm, or pick only the parts you are missing and keep your existing accountant for the rest. Both work.

You have to

Statutory

Anything filed with a regulator. Year end accounts and CT600, payroll filings, VAT, personal tax returns, confirmation statement. Prepared and signed off by our qualified accountants.

You should

Control

Hygiene that keeps the numbers true. Bookkeeping, supplier payment runs, receipt capture, payroll, and client account reconciliation where you hold client money. Data in, payments out, records straight.

You would like

Enablement

Turning the numbers into decisions. Monthly management accounts and KPIs, client and matter profitability, fee earner utilisation, lock up and work in progress, budget and rolling forecast. The layer where you should be getting most of the value.

When it matters

Tax advisory

Keeping more of what you make. Business and personal tax planning, profit extraction, remuneration and dividend strategy, capital allowances and R&D. Delivered by our qualified tax advisers.

And underneath all of it, data ready when the decision is. Not when the file lands next Tuesday. See the three stage engagement in detail.
