How can I adjust my invoice total to include shipping charges and miscellaneous adjustments?
Any miscellaneous amount you may want to associate to your quotes or invoices, can be added as ‘Adjustments’. The amount entered as adjustment is added to the invoice total. The ‘Adjustments’ field is displayed right at the bottom of the quote/invoice creation page and can be configured by following these steps,
Go to Settings – More Settings. This takes you to Preferences.
Scroll down to the section titled Select any additional charges you’d like to add and check the boxes Adjustments and/or on Shipping charges to include these on your quotes and invoices.
