I signed up last week as well and honestly I see a lot of potential in SAP. I do understand why companies that have been with them for awhile or larger operations are ready to see important functions operate flawlessly. And I agree, there are definitely some bugs. But, I can tell you whats made me feel comfidenent with my choice to go with SAP is email conversation I had with Jonathan yesterday morning at 2am, trying to make sure my problems are resolved that I've had setting things up. I appreciate knowing another business owner is working as hard as I am on their product. So far I've had pretty good support for all my problems.
Beyond that, the actual setting up of the system is definitely time consuming. But I look at it as an investment. Do the work now, to simply life once I'm busy. So far, I recommend the software.
