AI for accountants, surveyors and other professional services firms: win back non-billable time
By the Long Lever team · 6 min read · Last checked 7 November 2026
The short answer
In small professional services firms, AI saves the most time on non-billable work: pricing and writing proposals, onboarding new clients, chasing missing information, producing first drafts of routine letters and reports, and tidying up time records. Professional judgement, advice and sign-off stay with qualified people, and client data stays in business accounts covered by your policies.
Where does the non-billable time go?
Ask any partner where the week went and the answer is rarely the client work itself. It is pricing new work, writing proposals, onboarding clients, chasing them for records, writing up routine letters and catching up on timesheets.
That work follows patterns your firm already knows. That makes it a good fit for AI, with your people checking and signing off.
Where does AI pay back first?
| Where | What AI does | Who stays in charge |
|---|---|---|
| Proposals and fee quotes | Prices the work from your own past hours and drafts the proposal in your style | A partner reviews and sends it |
| Client onboarding | Builds the checklist, requests documents and tracks what has arrived | Your usual anti-money laundering and identity checks still apply |
| Chasing information | Drafts polite reminders for missing records and tracks replies | The client manager |
| First drafts | Drafts routine letters, file notes and report sections from your templates and notes | A qualified person edits and signs off |
| Time recording | Suggests time entries from calendars and emails for each person to confirm | Each fee earner |
From idea to a working process
“Every proposal starts from a blank page and a guess at the fee. I want to pick the services, see a fee based on what similar jobs really took, and get a first draft to edit.”
Practice manager, Long Lever Advisory (a fictitious example)
Fees are set from memory, so similar clients pay very different amounts, and the firm only finds out a job was underpriced when the time is written off.
Other processes professional services firms ask us to streamline
Not everything needs a screen. Some are automations that run in the background, some are AI agents that read and draft, and some are a simple screen for the team.

How do you protect client data and professional standards?
- Use business AI accounts that don’t train on your data, and set out what can and can’t be used in an AI policy.
- Keep advice and sign-off with qualified people. AI drafts; your professionals decide and stay accountable under your professional body’s rules.
- Check every fact and figure before anything goes to a client.
- Tell clients how you use AI where it matters to them, in your engagement letter or privacy notice.
How should a firm start?
- Pick one non-billable task that eats time every week, such as proposals or chasing records.
- Measure it now: hours per week and how long clients wait.
- Run a short trial of about four weeks, with every output checked.
- Measure again, then keep, change or stop it.

Questions people also ask
How can AI help a small accountancy or professional services firm?+
Mostly with non-billable work: pricing and drafting proposals, onboarding clients, chasing information, first drafts of routine letters and reports, and suggesting time entries.
Is it safe to use AI with client data?+
It can be, with business AI accounts that don’t train on your data, clear rules in an AI policy, and a qualified person checking every output. Avoid free personal tools for client information.
Can AI write proposals and fee quotes?+
It can price work from your own past hours and draft the proposal in your style. A partner should review and send it.
Will AI replace qualified staff?+
No. It takes routine drafting and admin off them. Advice, judgement and sign-off stay with qualified people.
Where should a professional services firm start with AI?+
Pick one non-billable task that takes time every week, measure it, run a short trial with every output checked, then measure again.
