# Put somebody on a percentage of each job

> If an engineer is paid a cut of every job, like 30%, set it once on their page and every job they do shows what's left after paying them. No timesheets needed.

Plenty of engineers aren't on a wage or a day rate. They get a cut of every job they do: 30% of a £1,000 gully change is £300, whatever it took.

Tell Mucka that once, and every job they do works out its own profit.

## Setting it up

Go to [**Settings → Team**](/settings?tab=team), open the person, and find **How they're paid on jobs** (on a phone, **Paid on jobs**).

- Choose **A share of each job**.
- Put in their percentage, like **30**.
- Choose whether it's **of the whole job** or **of what's left after materials**. Both are common, so pick the one you actually pay.
- Save.

To stop it, choose **Not set** and save. Somebody on a wage instead? Choose **A wage or salary**: [see how that's costed](/help/engineers/someone-on-a-wage). A person is on one or the other, never both.

You need to be able to manage the team **and** see job costs to set it. Engineers can't see anybody's percentage, their own included.

## What it does to a job

Open any job they're assigned to, and the money at the top now has their wages in it:

```
Invoiced        £1,000.00
Costs so far      £400.00
Dave on 30% of the job · 1 bought

£600.00 left on the invoice after costs and wages · 60%
```

That's £1,000 earned, £100 of materials and Dave's £300. Before the job's invoiced it works from the accepted quote and says so.

If your business is VAT registered, Mucka works from the invoice **before** VAT, because the VAT isn't yours. It takes the percentage of that too.

## Things worth knowing

**It goes on whoever the job is assigned to.** Reassign the job and the share follows the new engineer. If somebody else is helping on the job, their pay has to be known too (a share, a wage or hours), or the job won't show a margin.

**Logged hours win.** If somebody has logged hours against a job in Timesheets, those are the wages for that job, and the percentage isn't added on top.

**It never goes below zero.** On a share after materials, if the parts on a job cost more than it earned, their share is nothing, not a negative.

**It uses their percentage as it is today.** If you change somebody from 30% to 35%, their earlier jobs show 35% too, for now.

**Reports → Engineers uses it as well.** Each person's month shows the margin on their jobs once their share is set.

**A project's total doesn't include shares.** A site is usually invoiced as a whole, so there's no single job's earnings to take a cut of. Each day's own job still shows it.
