Just keep making Sales Orders when you do the jobs and edit them at will. At the end of the month, make one delivery of all the "pending orders" and invoice the delivery.
we have any physical products but only services. By the 30th, we make direct invoice based on one o two services items, that we send to customers. But, our problem, that we can not edit direct invoice when created to add fogotten item o edit existant one,
that's really frustrating because FA seems more suitable to businesses selling products and not services) ??.
Any idea to help ?
Thank you
