What is the difference between hours and billable hours on a work order?
On a work order, the Employee hours block has two columns with hours:
- Hours: how long your employee actually worked. Robaws uses these hours for the cost price in your post-calculation.
- Billable hours: how many hours you charge to your customer. These hours appear on the invoice and determine the sales price of the line.
By default both are the same. That way you can, for example, register an hour of travel time as a cost but not charge it, or charge a minimum of one hour for a short intervention.
How Robaws fills in the billable hours
If you fill in the Hours, or the start time, the end time and the pause, Robaws automatically fills in the Billable hours with the same number. Robaws also fills them in itself for work orders from Wappy, from a planning item or from an import.
Do you want to charge a different number? Then adjust the billable hours on that line. The hours worked then remain unchanged.
Rounding automatically
Do you always want to round the billable hours, for example per quarter of an hour or per hour? Then fill in Rounding minutes for employee hours via Settings > Work orders > Settings. Robaws then always rounds the billable hours up to that number of minutes.
Rounding minutes | Worked | Billable hours |
|---|---|---|
15 | 7 h 6 min | 7.25 h |
15 | 7 h 15 min | 7.25 h |
60 | 3 h 20 min | 4 h |
Robaws never rounds the worked Hours. So your cost price remains based on the actual hours. If you leave the field at 0, Robaws does not round.
Material hours
In the Material hours block, the Billable quantity works in the same way: Robaws takes over the quantity and you can adjust it per line. There Robaws does not round.
