If you're still tracking staff holidays in a spreadsheet, you're not alone — but you are taking unnecessary risks. Spreadsheets were never designed to manage leave. They break, they conflict, they give you zero visibility, and they create compliance headaches. In 2026, there's no reason not to use a proper staff holiday tracker. This guide explains what you're missing, what to look for, and how to make the switch.
Spreadsheets are brilliant for many things. Managing staff holidays is not one of them. Here's what goes wrong:
A single deleted formula, a mistyped date, or a copy-paste error can throw off an entire team's leave balances. And the worst part? You often don't discover the mistake until someone complains that their balance is wrong — weeks or months later. There's no undo button on a shared spreadsheet that five people have been editing.
With a spreadsheet, there's no formal approval process. Employees might email their manager, who replies "fine", and then someone manually updates the sheet. What happens when the email gets lost? Or when the sheet doesn't get updated? You end up with approved leave that isn't recorded, or recorded leave that was never properly approved.
Managers can't see at a glance who's off next week. Employees can't check their remaining balance without asking HR. There's no calendar view showing team availability. Everything requires opening the spreadsheet, finding the right tab, and interpreting the data — assuming it's up to date.
Who approved that request? When was the balance changed? Did the employee actually submit a request, or did someone just edit the sheet? Spreadsheets don't track changes in a meaningful way. If you ever face an absence managementdispute or a tribunal, you need a clear audit trail — and a spreadsheet won't hold up.
Even with Google Sheets or SharePoint, concurrent editing causes problems. Two managers approve leave at the same time, and one overwrites the other. Someone downloads a copy, makes changes offline, and uploads it — overwriting everyone else's updates. Version control and spreadsheets don't mix.
Beyond the obvious problems with spreadsheets, here's what you're actively losing by not using a proper system:
Without a team calendar, you can't see who else is off on the same dates. Two key team members book the same week, and nobody notices until it's too late. A proper tracker shows clashes at the point of request, so managers can make informed decisions.
During peak holiday periods like summer and Christmas, unmanaged bookings lead to days where half the team is off. A holiday tracker lets you set minimum staffing levels and block dates when needed.
UK employers are legally required to ensure employees take their statutory annual leave entitlement of 5.6 weeks (28 days for full-time). If you're not tracking balances accurately, employees might forfeit leave they're entitled to — which puts you at legal risk. A proper tracker automatically calculates balances, including pro-rata adjustments for part-time workers.
Adding up days, checking the calendar, cross-referencing bank holidays, calculating pro-rata entitlements — all of this is manual work that a holiday tracker does instantly. For a 20-person business, manual leave admin can easily consume 2–3 hours per week. Over a year, that's 100–150 hours of work that should be automated.
Not all holiday trackers are created equal. Here are the features that matter for a UK business:
A shared calendar that shows who's off on any given day. Managers can see the whole team at a glance, spot clashes before they happen, and plan workload around absences. This single feature eliminates more problems than any other.
Employees submit requests through the system. Managers get a notification and can approve or decline with one click. No emails, no chasing, no manual spreadsheet updates. The balance updates automatically.
The system tracks allowance, used, pending, and remaining leave — in real time. No formulas to break, no manual counting. Employees can check their balance at any time without asking HR.
UK bank holidaysshould be pre-loaded and automatically excluded from leave calculations. The system should handle England & Wales, Scotland, and Northern Ireland separately, since the bank holiday calendars differ.
Part-time workersare entitled to pro-rata leave. A good tracker calculates this automatically based on working patterns, including bank holiday adjustments for employees who don't work on the typical bank holiday day (Monday). Getting this wrong is one of the most common payroll and compliance errors.
The Bradford Factormeasures the impact of short, frequent absences. Calculating it manually is tedious and error-prone. A good tracker calculates it automatically and can trigger alerts when an employee crosses a threshold — so you can have early conversations rather than reactive disciplinary meetings.
For sickness absences of more than 7 days, employees need a fit note from their GP. A proper tracker lets you log fit notes against absence records and generate return-to-work interview forms automatically. This keeps your compliance records complete and audit-ready.
LeaveManageris built specifically for this problem. Here's how the leave flow works:
The entire flow takes less than 60 seconds. No emails, no spreadsheets, no manual calculations.
There are free holiday trackers available, and they work fine for very small teams (2–5 people). But once you grow past 10 employees, free tools start to fall short:
The cost of a proper holiday tracker is negligible compared to the cost of getting leave management wrong. One payroll error caused by incorrect leave data costs more than a year's subscription to LeaveManager.
"But spreadsheets are free!" Are they, though? Let's add up the real cost:
| Cost factor | Spreadsheet | LeaveManager |
|---|---|---|
| Software cost | £0 | £8/user/month |
| Admin time (20 staff) | 2–3 hrs/week (£50–75) | 10 mins/week (£0) |
| Error correction | 1–2 hrs/month | None |
| Compliance risk | High (no audit trail) | Low (full audit trail) |
| Employee satisfaction | Low (manual process) | High (self-service) |
| Real monthly cost (20 staff) | £200–300 in hidden time | £160 total |
A spreadsheet isn't free when you account for the time, errors, and risk it creates. For most businesses, a dedicated tracker costs less than the spreadsheet it replaces.
Switching from a spreadsheet to LeaveManager is straightforward:
Yes, if you have 5 or more employees. Below 5, a spreadsheet can work — but even then, the time savings and error prevention of a proper tracker often justify the cost. At 10+ employees, a spreadsheet is a liability.
Templates help, but they don't solve the core problems: no approval workflow, no notifications, no audit trail, no employee self-service. You're still relying on people to manually update a shared document correctly. Templates are a better spreadsheet, but they're still a spreadsheet.
With LeaveManager, yes. You can create unlimited leave types: annual leave, sick leave, TOIL, compassionate leave, study leave, and any custom types your business needs. Each type has its own allowance, accrual rules, and approval settings.
Yes. LeaveManager calculates pro-rata leaveautomatically based on each employee's working pattern. It also handles bank holiday adjustments for part-time employees who don't work on Mondays, which is one of the trickiest calculations to get right manually.
LeaveManager is fully GDPR compliant. Employee data is encrypted at rest and in transit, access is role-based (employees only see their own data), and you can export or delete data at any time. We provide a Data Processing Agreement (DPA) on request.
£8 per user per month. All features included — no tiers, no add-ons. For a 20-person team, that's £160/month. See pricing for full details.
