CraftMemo.com

This isn't necessarily as well suited for a stationery biz, but for all of you crafty chicas, CraftMemo.com is a pretty nifty idea.

From their site:
CraftMemo Helps You:
* Organize & keep track of all your craft goodies, projects & suppliers.
* Generate detailed lists of your inventory, out of stock items, what you need for a project and where to purchase them from.
* Plan what supplies you need & calculate the cost for your upcoming projects.

This seems particularly well suited for those with jewelry lines, but I can see many biz owners really benefitting from this.

And, yep...it's free.
