Untaken leave accrues. Taken leave can go unrecorded. Balances may inflate quietly for years — until leave that was already used is paid out. Muster detects leave from signals in calendars, Slack, Teams and email and checks it against your leave system, so your liability can better reflect reality.
Luxury Escapes found around 15% of its leave was going unbooked. Applied to four weeks of annual leave, that is 3 unrecorded days per employee each year. We’ve fixed that benchmark and let you change the workforce assumptions around it.
Benchmark: 15% of 20 leave days unbooked = 3 days per employee, per year

Check your numbersAnnual leave liability is the dollar value of leave your employees have accrued but not yet taken. Every pay cycle, untaken leave keeps building — and because it's paid out at the employee's current rate when they eventually leave or cash it out, it sits on your balance sheet as a real, growing cash obligation.
The problem isn't the accrual itself — it's the leave that gets taken but never recorded. A sick day here, a half-day school run there, a long weekend that quietly becomes a Tuesday. The HRIS never hears about it, so balances overstate what's actually owed. You end up paying out leave that was already used, sometimes years later.
Inflated leave balances aren't just an HR data issue — they can become a growing cash obligation that lands on finance every cycle.
When taken leave never reaches the HRIS, balances can overstate what's actually owed — creating a risk that the same leave is paid twice.
Accrued years ago, but settled at the employee's current salary. Every raise quietly inflates the liability.
Untracked leave can compound for years, increasing the provision that finance teams need to carry and defend.

Signals like calendar out-of-office events, Slack and Teams status, and email auto-replies. No forms, no app, no manager check-ins.
Muster weighs every signal before flagging a day, so sick days and long weekends don't slip through. You confirm before anything changes.
Every detected day off is compared with approved leave. Anything missing is flagged with its payroll impact before the pay run.
Leave that was taken gets deducted. Your liability stops inflating, and the number on the balance sheet is one you can actually defend.
Muster runs on signals your tools already produce, so there is nothing for managers or employees to fill in.
All features →Every detected day off is checked against your leave system, so you never cash out leave that was already used.
Back every leave provision with a day-by-day record of detected and approved leave, ready for finance and auditors.
No new system to adopt. Muster reads signals from the calendars, Slack, Teams and email your team already uses.
In 20 minutes, we'll show you the unrecorded leave hiding in your balances, the cash you're on the hook to pay out, and the monthly saving Muster delivers — using anonymised data from your own org.
