If you need to adjust the amount on an opportunity (someone forgot to use a discount code, for example), you will notice you can't change it by editing the opportunity.
Follow the directions below to change the price from the "products" object.
Navigate to the opportunity.
Scroll down to the "Products (Standard Price Book)" object. Select "Edit.
There are two ways to change the amount. Change the amount listed in the "Sales Price" field, or add in a Discount percent (it will automatically calculate the discount when you hit save). If you add in a discount amount, please also add in a discount code if relevant. This helps other team members understand why they received a discount. You can also add in details in the "Line Description" field.
Click "Save." This updates their Chargent Order, so the payment link in the invoice will update with the new amount. If they have lost their invoice and need a new one, see Sending an Invoice.
