If I go to: Report/Sales/Sales Profit, there is a column with title "Cost". How can I add the cost to the job?
The cost can only be calculated if you have inventory.
1. Please go to Inventory page. Under "Cost" category, you may set the Cost and the Unit Price (Selling Price) of your Inventory.
2. Create your invoice and select this inventory to your invoice item. Save and generate your invoice.
3. Now the cost will be calculated to the Sales Profit Report.
