After QBKS ate my Mac desktop you'd think I'd be angry but I'm taking it as a message. The fact is that QBCKS is the industry standard. I got my desktop issue behind me. Henry gave me Leopard for Christmas. The company bought itself 500GB Western Digital back up and a new 20" IMac is arriving Monday. I've researched the online edition of QBKS and it seems pretty good to me. Any other opinions? http://oe.quickbooks.com/product_info.cfm I like that I can do on the spot invoicing. We will use their merchant services. Plus it is all integrated and I don't have to coordinate third part software. Plus I can add users and grow with little additional cost. No huge software outlaw and I'm using a program I have a good grasp of which means no training costs. Way below my 500/mo budget on this matter. I believe security can be arranged to limit others access beyond invoicing. Also I can go PC or Mac depending on the Techs knowledge.
