Modification of your quote or invoice is always possible, even when this has been automatically generated. You can invoice for a new service by adding ad-hoc lines and costs. For each new line, you can specify the type of service by adding a description and any meta-information such as language combination, task, unit price, quantity, pre-translation, sub-total, fees or discounts. There is no limit to the number of new lines that can be added and you can organize the order in which to display them.
