Spreadsheets are free and easy to use, but are they the right tool for managing leave and tracking time off? While they work for some small businesses, over time spreadsheets can become a roadblock for teams trying to grow or handle more complex working patterns.

If you’re not sure whether to switch to HR software or not, this is the guide for you. We’ll explore the main reasons why businesses outgrow spreadsheets, what changes when you switch to HR software, and the costs of sticking with spreadsheets vs. investing in software. There’s also a simple assessment tool to help you figure out the best next steps for your business.

Why most businesses start with a spreadsheet (and why it makes sense)

Most small businesses start with a simple spreadsheet for all things HR — including leave tracking and holiday management. Spreadsheet tools like Excel or Sheets are free, familiar, and simple to use. It’s easy to open up a new spreadsheet, add data, set up a simple formula, and begin tracking leave. 

You can create a new spreadsheet in minutes and quickly share it with anyone that needs access. The sheet stores all the data you need to remember, so it can live in one place instead of across email threads. Your spreadsheet becomes an early HR system of record before you’re ready to invest in software.

Five signs you’ve outgrown spreadsheets for leave tracking

Spreadsheets work well at first, when your team is small and there’s nothing complex to keep track of. As your business grows and HR starts taking up more of your time, you start to wonder if there’s a better way to track leave. 

Most small businesses find they outgrow spreadsheets when they reach one (or more) of these stages:

  • Your team size has grown to 10+ people: Every fresh hire is a new line in your spreadsheet, and it becomes difficult to track annual leave allowances, holiday clashes, and shift patterns as your headcount increases.
  • Errors pose a real risk: Spreadsheets are open to user error, and entering the wrong dates, hours worked, or time-off taken can create serious problems for payroll preparation and compliance tracking.
  • The manual admin is overwhelming: Managers spend too long updating spreadsheets, troubleshooting formulas, and manually checking leave balances, instead of making progress towards more important goals.
  • You need to track more complex working patterns: A simple formula works for tracking standard full-time hours workers who are entitled to 5.6 weeks of holiday, but once you introduce part-time, term-time working, flexible working, and other complexities, the system becomes increasingly difficult for most spreadsheet users to manage.
  • You’re worried about compliance: Manually recording information in spreadsheets can open you up to HR compliance risks which can outweigh the benefits of sticking with a familiar system.

Spreadsheets aren’t a bad starting point, but they tend to break as you grow. It’s hard to scale systems when they live on paper, in emails, or in spreadsheets.

Should you switch to HR software for leave tracking?

The right time to switch to HR software is different for every small business. For some, it’s when they realise that it’s taking too much time to update spreadsheets every month. For others, it’s because they want to introduce more systems, processes, and policies, and it’s easier to do that with HR software in place.

If you’re not sure what’s right for you, use this simple assessment tool to guide you on what to do next:

What changes when you switch to HR software

Saying goodbye to manual HR admin and moving to a system that handles leave management for you removes a huge burden from founders and managers: their time is once again free to work on tasks that move the business forward.

Compare life before and after HR software:


Before
(with spreadsheets)

After
(with HR software)

Submitting a holiday request

Employee sends an email to their manager

Employee submits request directly

Approving holiday requests

Manager checks calendar, looks for clashes, emails back to say yes or no

Manager is alerted to any clashes automatically, then can approve or deny in one click

Calculating time-off allowances

Create (and rely on) a formula to be correct in every situation

HR software automatically calculates based on employee type, working hours, and any relevant information

Calculating leave balances

Create a formula that updates when information is changed manually

HR software automatically calculates balances according to real-time data

Checking who’s working and who isn’t

Manager checks a shared calendar or spreadsheet, which may not always be up to date and accurate

Manager checks the shared calendar in the HR system, which is updated in real time

“Before Charlie, [time-off management] was something people had to think about and taking holidays almost became another job on the to-do list. It’s now so seamless we don’t even have to think about it.”

Is it worth paying for HR software?

There are many affordable options for smaller teams in the UK, with HR software pricing at around £4 per employee per month, or from £20 per month for flat-rate plans. Small business HR software is designed to be budget-friendly, but whether it’s worth the cost or not depends on your goals and requirements. 

HR software with a leave management system comes with an added cost (compared to using spreadsheets), but for most businesses the added features, ability to automate parts of the process, and reduction in errors make it a useful investment.

Free, or included with a Microsoft or Google subscription

Both all-in-one HR software and standalone time tracking tools are valid options for small businesses. The main difference between the two is the range of features included, and what you can use the software for beyond time-off management.

Spreadsheets are free but they come with hidden costs, like: 

  • Human error: It’s easy to enter the wrong figure, accidentally break a formula, or make an incorrect calculation. These errors can lead to real problems further down the line — especially if they affect payroll calculations.
  • Admin time: Managers spend hours every week updating spreadsheets or answering questions about leave balances or holiday requests. This admin cost adds up significantly the longer you stick with spreadsheets.
  • Technical expertise: Anything other than a basic spreadsheet requires technical knowledge to create, adapt, maintain, and fix formulas and settings. This can lead to you relying on one person to keep it running, or paying an external consultant to do the work for you.
  • Compliance concerns: Spreadsheets lack the audit log, access controls, and automatic data retention periods that come with using dedicated HR software. Non-compliance with regulations can lead to trust issues, data protection or security risks, or potential fines.

HR software can reduce the likelihood of running into these admin and risk-related issues. Every business is different, so consider whether the benefits of leaving spreadsheets outweigh the financial costs.

Our verdict

If you’re happy with your current setup, stick with spreadsheets.If you only want to streamline holiday and leave tracking, consider a standalone time tracking tool like Timetastic.If you want to organise time-off management alongside other aspects of HR, consider an all-in-one HR system like Charlie.

Frequently asked questions

How do I stop double-booking staff on holiday?

The best way to stop accidental holiday clashes and double-booking is to use a staff holiday planner or leave management tool that automatically alerts you to issues before they’re approved.

How much admin time should tracking leave take for a small team?

Leave tracking for a small team shouldn’t be overwhelming for managers. With manual systems it can take several hours per week or month, depending on the size of the team and the processes you use. If you automate time tracking or use dedicated software, managers can get the information they need in moments.

When should a small business switch from spreadsheets to leave management software?

Small businesses should switch to leave management software when using spreadsheets becomes overwhelming, too time-consuming, or too much of a compliance risk. For some businesses, this happens quickly, while others are happy to use spreadsheets until their team size grows beyond 10+ people. 

How much does leave management software cost for a small business?

Leave management software for small businesses can cost as little as £1.20 per employee per month if you choose a simple, standalone time tracking tool. For all-in-one HR software that includes time-off management and other core HR features, expect to pay around £5 per employee per month — or from £21 per month for a small team with Charlie HR.
