We have a partner company that we have been working with for some time now. Product lines we don't carry we obtain from them and vice versa. The problem is that it's quite a hassle everytime we need to ask them for pricing on a product they carry. We need to call them, interrupt their work, and have them call us back or sit on the phone until they find the price.

I'd like to somehow share both our dabases so looking up each others pricing information would eliminate much of the hassle. Is this possible, and if so, what would be the best approach?
