I would like some advice on options to use Zoho to solve a problem for us.  I am a new user.

I run a supply business in the construction industry.

We have clients and contacts and I appreciate the possible linkage between them.  In addition we have a third dimension in that we are dealing with multiple clients and subsequently contacts on the same Potential Construction project.

Ie we might be dealing with John at Company A, Mary at Company B and Paul at Company C who are all competing for work at a 50 story building called the Queen St Tower.

I want to link our dealing with these three people and their companies with the "queen St Tower" Project. (not Zoho project).

Has anyone any suggestions on how we can get Zoho to track this three way linkage?

Thanks for your help
