Thank you for taking the time to respond.

However, what you are describing is partial or split invoicing as it bears no context of time. Progress invoicing requires the minimum details of previous and current. I can accept that the feature requested is currently unavailable, but I feel strongly that it is misleadingly misnamed.

The estimate summary feature is similarly underwhelming, since it is not applied at the line item level of detail.

Overall, I’ve found QBO to be a potent replacement to the Desktop version, but in this respect, it still needs work. I have previously filed feedback requests saying the same. With luck, additional QBO users will add their voices and votes towards implementation. As it stands currently, it is such a showstopper, that I am evaluating alternatives.
