Time recording software for accountants
For UK practices that bill for their time, or need to know whether their fixed fees are paying for it.
Why accounting practices record time
Most practices have moved to fixed fees for compliance work, and clients like the certainty. But a fixed fee does not remove the need for a time record. It changes what the record is for. You are no longer billing from it; you are checking whether the fee covers the work.
Without that record, a client paying £150 a month for bookkeeping and a VAT return looks as healthy as any other. With it, you can see that the same client sends a shoebox of receipts every quarter and takes eleven hours a month. That is the evidence you need to reprice at renewal, and the reason most practices that stop recording time end up undercharging.
For advisory, ad hoc and hourly work, the record is still the bill. Unrecorded phone calls and quick queries are where the fees leak away.
What to look for
- Six-minute units. The usual professional services convention. The software should round for you.
- Rates per person, client and activity. A partner's hour on tax planning is not worth the same as a junior's hour on data entry.
- Fixed fees alongside hourly work. Time against a fixed fee must still be recorded, so recovery can be reported.
- Unbilled time and write-offs. You need to see what is waiting to be billed and approve anything being written off.
- A route to the invoice. Recorded time should become a draft invoice in your accounts package without anyone retyping figures.
- Client onboarding. For limited company clients, the details are already on the Companies House register. Typing them in again is wasted time.
How Posttime handles it
Posttime runs in the browser, so there is nothing to install. Time goes in with a start/stop timer or typed straight in, rounded to your units, with the right rate applied. Everyone can see their running total against a seven-hour chargeable day.
Fixed-fee and non-billable work sit beside chargeable time, so the reports show where every hour went by person, client and activity. When you bill, unbilled time becomes a draft invoice and posts to QuickBooks Online in one click. On the Team plan, write-offs go through approvals.
New limited company clients are added with a Companies House search that fills in the record from the register. The Firm plan adds AutoBank, which imports the bank feed, matches payments to invoices and produces a profit and loss and balance sheet. There is also quarterly readiness for Making Tax Digital for Income Tax.
Where Posttime is not the right fit
- It does not prepare accounts or tax returns. Keep your accounts production and tax software; Posttime handles time, billing and the client record.
- QuickBooks Online is the only direct accounts connection. If you invoice from Xero or Sage, you would export to a spreadsheet instead.
- It is browser-based only, with no desktop install. It works on phones and tablets through the browser.

Questions accountants ask
What is the best time recording software for a small practice?
Look for six-minute units, per-client and per-activity rates, recovery reporting against fixed fees, and a way to turn unbilled time into an invoice without retyping. Posttime is built for UK practices on those lines, from £9 per user per month with no VAT added. If you only need a basic timer, a free tool such as Clockify may be enough.
Why record time if we charge fixed fees?
On a fixed fee the time spent is the whole cost of the job. The record shows which engagements overrun, so you can reprice at renewal with evidence.
Does it work with QuickBooks and Xero?
Draft invoices post directly to QuickBooks Online. There is no direct Xero connection; Xero users export to a spreadsheet.
Is it a full practice management system?
No. Posttime covers time, billing, client records, bank reconciliation and firm admin. It does not prepare accounts or tax returns.
How much does it cost?
Solo £9, Team £15 and Firm £19 per user per month, with a 14-day free trial and no card required. No VAT is added. See full pricing.
