Where are "Customers" in Zoho?

I can't find where Potentials go in Zoho after the stage is changed to "Closed-Won." Do they become Customers? In our business, after a Potential job is won (quote is accepted), we consider them customers and during this stage, we have tasks related to fulfilling the order that we would like to continue to track in Zoho. Does Zoho define this stage differently? I noticed on the Activities Page that there is a column for tasks related to Customers, but I can't figure out how Customers are created in Zoho.
