# What is Smart Labour?
> Understand what Smart Labour is and how it works in ServiceM8.
Smart Labour allows your job labour to automatically be set based on your check in and check out timer.
**To use Smart Labour:**
## Open a job on the ServiceM8 app
## Tap Start Job to check in to the job
## Tap Billing
## In the billing screen, tap Add Item/Service
## Tap Smart Labour
## Tap to select the appropriate labour rate from the list of labour items
**Note:** the items available to select in Smart Labour are automatically chosen from your Materials & Services database. Any materials with the word "Labour" or "Labor" in the name will be available to use with the Smart Labour feature.
## And if you wish to round your timer to the nearest 15 min / 30 min / 60 min, tap the rounding option.
## Tap Set Labour
## That's it! Your labour fee for the job is now increasing in-line with your job timer.
## To stop the labour increasing, tap the job checkout button to stop the timer and finalise your labour fee.
