Salesman Commission

Commission can be calculated on invoices for sales people using the following methods:

• By invoice total less shipping and taxes - The commission rate set for each sales person is used (Income -> Sales Personnel)
• By inventory item - Set a commission rate for your inventory items in the Item Edit screen (Inventory -> Items)

Otherwise, salesperson commission is manually calculated. They can be set up as a sales person (Income -> Sales Personnel). 

By going to Reports -> Billing -> Summary of Invoices and choosing Sales Person from the Order By drop-down you can see a list showing a total of sales and profit for the sales person and manually calculate the commission.
