Kippax is a Swiss motorcycle parts distributor for whom I have built a FileMaker 12 based stock and invoicing solution.
This solution works in 4 currencies, automatically reserves stock on provisional invoices and works from an orders screen allowing easy identification of stock which needs to be bought in.
Kippax is also an interesting in that we have a very productive working relationship but have never met in person proving that FileMaker development can be done effectively from anywhere.
