General Billing Principle
At Combo, your invoice is calculated each month based on two main criteria:
The maximum number of active establishments during the billing period.
The average number of active employees over the last 4 weeks.
Additional options may be added (e.g. time-clock, distribution of pay slips).
💡 Automatic billing starts from the 3rd month after you activate your account.
1. Number of Active Establishments
We take the maximum number of establishments active during the billing period.
🔎 If you have 2 establishments active from April 23 to May 15, then only 1 until May 23 → your May 23 invoice will count 2 establishments.
2. Average of Active Employees
An employee is counted as active if they have at least one shift or one scheduled absence in a given week.
Calculation:
Count the number of active employees each week.
Take the average over the 4 weeks prior to billing.
Round down to the nearest whole number.
🔎 Example over the past month:
Week 1: 17 → Week 2: 20 → Week 3: 13 → Week 4: 15
The average is 16.25, which is rounded down to 16 billed employees.
3. Subscribed Options
Some paid features (e.g. time-clock, pay slip delivery) are billed based on the same average of active employees, similar to the main subscription.
💡 To optimize your billing:
Close contracts of inactive employees
Remove scheduled shifts and absences
Archive unused establishments
