An online holiday booking system that does one job brilliantly
Most HR tools bolt leave onto a dozen features you will never use. Book Time Off is a dedicated staff holiday booking system: request, approve and track annual leave in one place, so nothing slips through email and no two people are accidentally off at once.
Book leave in seconds
Staff pick their dates and submit. Days remaining update automatically, including custom pro-rata allowances for part-time and irregular-hours workers.
Approve in a click
Managers get the request, see who else is off that week, and approve or decline, including one-click approve or decline straight from the email.
See who's off at a glance
Calendar and team views show every booked day with today highlighted, so you can plan cover before you commit and set a maximum-absent limit per team.
Bank holidays and part-timers handled
UK bank holidays load automatically from the GOV.UK feed and are never deducted, and you can pro-rate allowances for any working pattern.
Set allowances, load UK bank holidays automatically, approve a request and see the whole team's leave in one place. 30 days free, no card required.
Why UK small businesses choose Book Time Off over a spreadsheet
Spreadsheets don't stop clashes, don't count down allowances, and get out of date the moment someone forgets to fill them in. A proper employee holiday booking system keeps one source of truth that everyone trusts.
| What you get | Book Time Off | Spreadsheet |
|---|---|---|
| Automatic days used and days remaining | Yes | No |
| Clash and capacity control (who's off when) | Yes | No |
| One-click manager approval | Yes | No |
| Part-time allowances and UK bank holidays | Yes | Manual |
| Works on mobile | Yes | Barely |
| Cost for a 10-person team | £10 / month | Free but risky |

A staff holiday booking system is an online tool that replaces spreadsheets and email chains for annual leave. Employees request time off, a manager approves it in a click, and everyone can see who is off, with days used and days remaining tracked automatically.

Book Time Off is free for 30 days with no card required, then £1 per user per month. It is a paid product, not a free tier. For a small UK team that flat £1 often works out cheaper than a free tool once you hit its user caps or feature limits.
