I like that it allows for multiple users (if you have more than one) so they can all access each other's data without having their own copy of shiperp in addition to your main account! You cannot share work orders between different clients within this system - only be able to view them from another user if using same client as original owner/creator etc.
This is really important because we need different people working off the exact same information but not actually seeing what others are doing until after final approval has been given by our CEO or CFO which could take days sometimes weeks before getting approved internally. We also use Ship ERP at my previous job where i was responsible solely for managing invoices & payments made through paypal into our accounting software via bank transfer.
