I am looking for software that can invoice in multiple currencies (in
one invoice), and has inventory management capability (stock control),
preferably for 2 locations (multiple locations).

It should be low in cost (some free or shareware packages are
available too - would prefer obviously a demo before purchasing), and
ideally 2 people should be able to access the program from 2 different
locations over the internet i.e. I would like an employee to be able
to update it from another site, connected over the net, however this
may possibly have little to do with the program and is just a question
of how to give access to the program to someone else via the net. I
would like however to limit an employees access to certain data i.e.
that they can enter new inventory but not necessarily see the purchase
cost or source of items.

If a program has all of the above but without multiple currencies, I
would still consider it. But multiple currencies is much preferred.

This software is for a home-based business, generating few invoices
weekly, but stocking approximately 60 different products.
