It has been so easy to use and understand with no glitches or other problems. The app itself is very informative and easy to navigate through. No complaints! Everything I need to know about my packages is right there within each one. You can't have too many of them! My clients, clients' clients, and customers are always asking questions about their deliveries and how I do it. They love having everything available in one spot. It's very easy to use with clear instructions. I like how you can select which day your packages are delivered or picked up from time of order. The customer service has been great so far! There isn't much to dislike about this program at all. If you're looking for an app that will help organize deliveries/pickups it does exactly what we needed.
