I guess there is no one monitoring this forum to help us with answers.
As far as I can tell, these two programs are very limited in what they can do at this time. The interesting feature is that they are available online to other locations of your company or if you are out of town. But other than that, Inventoria just lists inventory and Express Accounts just lists invoices. You have to enter your items in Express Accounts separately I guess.
They advertise the software as having allot of features. I don't see it yet. Programs seem limited. I can't seem to find a decent inventory and invoicing program. Don't like Quickbooks that much and Filemaker is limited. You would think someone could put out a logical and effective program that covers the different business options for invoicing and inventory. If you know of one you really like, please let me know.
