I just learned the hard way that iBiz is no longer supported and does not run on Sierra. I downloaded a trial of Studiometry and I think it will work great for me.
Unfortunately, I do not have time to properly transition and I have mounting invoices. I may have to come here with some very basic questions until I get this digested. I have created a project and I'm ready to go with my first invoice, but I can't figure out how to reset the invoice number. I'm literally waiting to get an answer so I can get this invoice out tonight. Thanks!
