Flat great buy it

This app is great once you learn your way around it. I use it every day not for invoicing but to keep track of all my time and pay from work. It lets you do as many intries as u need on the same date up to mid night of course. Calculates overtime as well and its right on and it does perdium /mileage are w/e u would need to get reimburste with. The only down fall i see is i wish you could change it from regular time to MARINE TIME but other than that great app
