Made an investment in IPads for myself, the owner, and bookkeeper and operations manager. Have 2 maintenance crews + 1 part time, as needed, project crew. I presently use Quickbooks. Would like to be able to send and receive work orders to and from the field; manage chemical applications, estimates and landscape design. What are you using and are you happy? Is there a clear leader/best in class? Have seen everything from relatively cheap software of $200 to $4,000.00 Any real-world experiences would really be appreciated.
