Setup for a service based business

I apologise if this has been asked before but a search of the forums didn't turn up what I was looking for.

I am looking at setting up Zoho CRM for a consultancy based business and so there are no products as such. This is fine as I can create a product which is time based. However, I do not seem to be able to get rid of the concept of having quantity in stock. I have a unlimited supply of time!

How can I bend Zoho to my will and get rid of the stock control?

Thanks

Neil
