To add a discount to an invoice:

1. Edit or create an invoice
2. Add a separate line item with a negative amount for the discount
3. The total reflects the reduced amount
4. Save the invoice

There is no separate discount field; a negative line item is how you apply a discount in MyCompanyDesk.

Tip: Clearly label the discount line (e.g. "Early payment discount -5%") so the customer understands the deduction.

Line-level discount

Each line item can also carry its own discount:

1. Add or edit a line item
2. Choose the discount type: percentage or fixed amount
3. Enter the discount value

A percentage discount cannot be higher than 100%. The discount value cannot be negative. If you want to give the line away entirely, set the percentage discount to 100%.
