Workforce management ROI is the value a system gives back each year, minus its cost, divided by its cost.
For an event agency, most of that value is admin time. At 2026/27 employment costs, every 10 hours a week of booking admin costs about £9,800 a year. It is also the first number your MD will ask about when you propose workforce management built for agencies.
The case needs two numbers first:
- What an admin hour really costs, and
- How many hours your team spends.
Everything else follows from those two, including payback and the one-page summary for your MD. Most agencies reach this question at the point where spreadsheets stop scaling, when admin grows faster than the business.
How to Calculate Workforce Management ROI
To calculate workforce management ROI, take the value a system recovers each year and subtract its annual cost. Divide the result by the annual cost and multiply by 100.
Three formulas cover the whole calculation.
- ROI (%) = (annual value recovered − annual cost) ÷ annual cost × 100
- First-year ROI (%) = (annual value − annual cost − one-off setup) ÷ (annual cost + setup) × 100
- Payback (months) = one-off setup cost ÷ (annual net benefit ÷ 12)
The cost side comes straight from a supplier’s quote. The value side takes more work, because it rests on hours nobody has counted yet.
Most of the value line is admin time, at about £18.90 an hour in 2026/27.
Step 1: Measure Four Weeks of Real Admin Time
Ask everyone who touches bookings to log their admin time for four normal weeks. Split it by task, from availability chasing to client reports. Four weeks smooths out one quiet week or one busy peak. The worksheet further down uses the same task lines.
Step 2: Price Each Hour at Its True Cost
Salary alone understates what an admin hour costs. Add employer National Insurance and the employer pension contribution to the median pay for the role. For an events coordinator in 2026/27, that comes to about £18.90 an hour. The table below shows every figure and its source.
Step 3: Estimate What a System Removes
No system removes every hour, so test a range. WiseUp Team Building reported around 80% less staffing admin after moving to Liveforce. Run your numbers at 40% and 60% as well. The calculator shows all three results side by side. That range gives a fair view of the workforce management software return on investment.
Step 4: Add the Full Cost, Then Compare
Take the annual software cost from your quote. Add the one-off setup, which is mostly your own team’s time on migration and training. Then run the same workforce management ROI formulas.
A case that stays positive at 40% will survive a sceptical MD.
The Real Cost of Manual Workforce Management in 2026/27
An hour of booking admin costs an agency about £18.90 in 2026/27, once employer on-costs are added. Every workforce management ROI calculation starts with that price.
Median pay comes first.
- Events managers and organisers earn a median £16.42 an hour, or £32,163 a year (ONS, 2025).
- Employers then pay 15% National Insurance on earnings above £5,000 a year (HMRC, 2026).
- The minimum employer pension is 3% of qualifying earnings between £6,240 and £50,270 (The Pensions Regulator, 2026).
- Those on-costs add about 15% to the salary.
- The £18.90 is a conservative number. It leaves out holiday cover, office costs and management time, so the true cost of an admin hour is higher.
Crew time has a real cost too.
- The National Living Wage is £12.71 an hour for workers aged 21 and over from 1 April 2026 (gov.uk, 2026).
- Crew on irregular hours also accrue holiday at 12.07% of the hours they work.
- The guide to zero-hours holiday pay and the 12.07% rule shows that calculation step by step.
- Together, they put one crew hour at £14.24 before any employer National Insurance.
At these rates, an hour of booking admin costs more than an hour of crew time on the floor.
The table sets out each figure and its source.

Where the Admin Hours Go in an Event Staffing Agency
Booking admin in an event agency splits into seven lines of work. Five sit around the booking itself: availability and confirmations, shift allocation, late changes and cover, briefings, and compliance documents. Two come after the event: collecting timesheets and client reports with invoice checks.
Two money leaks sit outside admin time. Pay runs need fixing when hours arrive late or wrong. Crew timesheets also carry minutes nobody can confirm, such as a late finish written from memory.
Add your own hours to the worksheet below, or press “Use the 10-hour example” to see how it works. It opens blank, so every figure is yours.

Hourly admin costs: median full-time hourly pay excluding overtime from the ONS Annual Survey of Hours and Earnings 2025 (provisional, Table 14): events managers and organisers £16.42, administrative occupations £16.00, office managers £20.05. Each is loaded with 15% employer National Insurance above £5,000 a year and a 3% employer pension on qualifying earnings of £6,240 to £50,270 (2026/27). Crew cost: £12.71 National Living Wage from 1 April 2026 plus 12.07% holiday accrual. This is an estimate for planning, not financial advice. Your own payroll data is always more accurate.
Why the Cost Grows Faster Than the Business
Admin grows with crew, events and clients. Each new client brings its own rates, roles, briefings and paperwork, so the booking desk handles more lines per event. That is also why workforce management ROI tends to rise as an agency grows.
CASE STUDY EXAMPLE:
Active Training World shows the pattern. The organiser runs around 80 triathlon and running events each year. For years, the details of each event lived in spreadsheets, rebuilt event by event. The same kinds of marshals and the same shape of shifts were typed in again from the top. Each hour of that re-keying costs £18.90, at the first event or the eightieth.
Growth adds admin long before it adds the budget for another coordinator.
Workforce Management ROI Worked Example: 10 Hours a Week
Ten hours a week of booking admin costs an agency £9,828 a year at 2026/27 rates. At the reduction WiseUp Team Building reported, about £7,862 of that comes back each year.
Ten hours is a unit for the maths. It says nothing about a typical agency. Each agency should scale it to the hours its own team logs.
- Median pay, event managers and organisers: £16.42 an hour, £32,163 a year (ONS, 2025)
- Employer National Insurance: 15% × (£32,163 − £5,000) = £4,074.45
- Employer pension: 3% × (£32,163 − £6,240) = £777.69
- Loaded annual cost: £32,163 + £4,074.45 + £777.69 = £37,015.14
- Loaded hourly cost: £16.42 × 1.1509 = £18.90
- Ten hours a week for a year: 10 × 52 × £18.90 = £9,828
- At around 80% of admin removed: £9,828 × 0.8 = £7,862
The 80% is WiseUp Team Building’s reported result after its move to Liveforce. It is one customer’s outcome, so it belongs at the top of the range. Every workforce management ROI case for an event agency runs on this same arithmetic.
Double the hours and both figures double: 20 hours a week costs £19,656 a year.
The crew side works the same way. One crew hour at the Living Wage, with 12.07% holiday, costs £14.24. Fifteen unverified minutes on a shift therefore cost £3.56. Across 1,000 such shifts a month, that is £3,560 a month, or £42,720 a year. The 1,000 shifts is also a unit, so each agency should use its own shift count. Timesheets recorded against each shift give every one of those minutes a record.

Starts with the worked example: 10 hours a week at £18.90 an hour. Send your worksheet total or type your own figure.
WiseUp Team Building reported around 80% less staffing admin after moving to Liveforce. Test lower figures too.
Setup cost is mostly your own team's time: data migration and training hours multiplied by their hourly cost (£18.90 for an events coordinator).
The default £9,828 is 10 hours a week of booking admin at £18.90 an hour: the median full-time hourly pay of events managers and organisers (£16.42, ONS Annual Survey of Hours and Earnings 2025, provisional) plus 15% employer National Insurance and a 3% employer pension (2026/27). The 80% reference comes from WiseUp Team Building's published case study. Every agency is different, so treat the result as a planning estimate, not financial advice.
Hard ROI vs Soft ROI: Pay, Compliance and Capacity
Hard ROI is the part of workforce management ROI that an agency can count in cash. That means admin hours, pay-run fixes and unverified crew time.
Soft ROI is real value that is harder to bank, such as capacity, retention and lower compliance exposure.
Capacity is often the largest soft return for a growing agency. Taking on more events without another coordinator avoids a real cost. One more events coordinator at the median costs about £37,015 a year once National Insurance and pension are added.
Capacity is the one soft return an MD can still put a number on.
Compliance exposure belongs in the case as a risk line, kept out of the savings total. HMRC can charge a penalty of up to 200% of minimum wage arrears, capped at £20,000 per worker (gov.uk, 2026). In 2024/25, HMRC found £5.8 million of arrears owed to more than 25,000 workers. It issued 750 penalties worth £4.2 million in the same year (Department for Business and Trade, 2025).
Illegal working carries civil penalties of up to £45,000 per worker, or £60,000 for a repeat breach (Home Office, 2024). The agency carries out its own right to work checks, and organised records make those checks easier to evidence.
Retention and client confidence complete the soft side. Fewer double bookings and late briefings help an agency keep good crew and repeat clients. They sit alongside the wider benefits of workforce management software, and they are hard to price. Put soft ROI in the business case, but let the hard number carry the decision.
What Payback Period Should an Event Agency Expect?
Payback depends on the agency’s own hours and quote, so it has to be calculated. The payback period is the one-off setup cost divided by the monthly net benefit.
Monthly net benefit is the annual value recovered, minus the annual software cost, divided by 12. Payback is usually the part of workforce management ROI an MD asks about first.
Every hour cut from setup brings payback closer, at £18.90 an hour.
Two things move the answer most. Setup size is one, and most setup is staff time. The other is how fast bookers drop the old spreadsheet.
Look for the savings in stages. Availability and allocation time should fall from the first event on the new system. Timesheet time should fall at the first pay run. Capacity shows in the next peak season, when the same desk handles more events. WiseUp Team Building eliminated double bookings after moving its scheduling into one system.
Hidden Costs That Shrink Workforce Management ROI
Hidden costs are one-off and running costs that sit outside the quote. Most of them are the agency’s own time. They reduce workforce management ROI at £18.90 an hour, like any other admin.
- Setup and data migration: moving crew records, rates, roles and client details takes time. Price those hours at £18.90.
- Training and adoption: the office team and the crew both need time to learn it. Liveforce offers free 1:1 training and an online academy through support and onboarding.
- Running two systems at once: for a few weeks, both the spreadsheet and the new system need updating. Plan the switch for a quieter period.
- Payroll and accounts exports: timesheet exports need mapping to the format the payroll process expects. Liveforce is not a payroll provider, so the agency still runs payroll.
The guide to migrating from spreadsheets to workforce management software sets out a phased plan that keeps each line small.
The longer the old spreadsheet stays in use, the bigger the setup cost gets.
Why Some Rollouts Never Show a Return
Some rollouts never show a workforce management ROI for four common reasons. Nobody measured a baseline, so nobody can prove a change. Bookers keep a shadow spreadsheet, so the old admin never stops.
WhatsApp stays the channel everyone uses for changes and cover. Only one part of the platform gets used, usually scheduling. Each of these is a management choice, which makes each one fixable.
How to Present the Workforce Management Business Case to Your MD
Present the workforce management business case on one page, built from numbers the MD recognises.
- The problem in one line: state the problem with the four-week baseline hours attached.
- The yearly cost of the current way: use the worksheet total, with the hourly cost shown next to it.
- The value, stated three ways: give the result at 40%, 60% and 80% removed, from the calculator’s sensitivity table.
- The full cost and the payback: show the yearly cost from your quote, the setup cost and payback in months.
- A pilot, then a decision: run one event or one client first, with a date to review the numbers.
Keep compliance exposure on the page as a separate risk line. Leave out any figure the MD cannot check.
Every number on the page should trace back to the worksheet or the quote.
Workforce Management Metrics to Track After Go-Live
Measure the same things at 30 and 90 days after go-live, against your baseline.
Track admin hours per week and the time it takes to fill a full shift. Track timesheet approval turnaround and pay-run corrections per run. Count double bookings, and check that late changes reached everyone affected. These workforce management metrics turn the pilot into evidence. They prove the workforce management ROI at the next budget meeting.

How Liveforce Turns These Cost Lines Into Recovered Time
The seven admin lines in the worksheet are usually seven separate jobs in separate tools. Each tool holds part of the picture, so the booking desk re-keys the rest.
Liveforce is a workforce management platform built for event-led businesses that manage large temporary or freelance teams across multiple projects, locations and clients.
Availability requests go to the right people at once, and replies land in one view. That replaces rounds of calls, texts and group chats. Scheduling runs several events on one board. A clash is flagged the moment someone is booked twice, before it becomes a double booking. Nobody has to cross-check spreadsheets by hand.
Each cost line in the worksheet maps to one part of the platform.
- Changes and briefings go to a role, a team or one person by email, push, SMS or in-app chat.
- Automated reminders cover confirmations and check-ins, so WhatsApp chains and phone rounds drop away.
- Timesheets are approved from scheduled hours or check-in and check-out times, with every edit in an audit trail.
- Approved hours export as payroll-ready reports in the agency’s own format. Liveforce does not run payroll, and the agency pays its staff.
- Compliance documents sit against each worker’s profile, where the agency can find and update them. The agency still carries out its own checks.
Paul Belsey, Business Development Manager at WiseUp Team Building, described the result. “We’ve reduced staffing admin by around 80%, eliminated double bookings, and improved overall organisation across the team.”
The platform is built for event staffing, promotional and experiential, hospitality and catering agencies, festival suppliers and venues. Crew see their shifts, briefings and updates in the Crew App.
The Business Case Starts With Your Own Numbers
A workforce management ROI figure persuades only when the hours behind it are real. Four weeks of logged admin, priced at £18.90 an hour, gives the case its base. The worksheet and calculator turn that base into a payback figure and a decision.
Figures are for the 2026/27 tax year and are general information, not financial, tax or legal advice.
