We are currently selling apartments in a project called "Cartagena Laguna Club". We use Zoho CRM for contacts management. When a contact wants to buy an apartment, we move the contact to lead, then integrate with invoice so we can build a payment plan and keep track in the future for the payments. I'm in charge of managing Zoho Invoice. When I integrate the lead info, there is some information that we are missing that I manually enter, one of those fields is the "Apartment" the lead wants to buy, that's why I created the custom field "Apartment", then, when I'm creating the invoices for the lead, corresponding to each payment he/she will have to make, I created another field "Apartment" so we can see in the invoice for which apartment the lead is paying for. What I want is that if I already know which apartment the lead is buying because I specify that in the contact info, I don't want to type it for every invoice I'm creating. There are like two more fields that repeat themselves in the invoice that i already specify in the lead info.

I'm attaching a pic of an example of the invoice and the contact info (is in spanish by the way)

In the left when you see "Cliente" is the lead info but i'm not showing there the "Apartment" as you suggested before, I'm doing it in the "Apartment" label of the invoice in the right. In this case "Apartment", "Parking Lot" and "Deposit" is information I have to specify when I'm creating the lead or updating when I integrate with CRM, but If I decide to use your suggestion it would put that info in the left in "Cliente" and we don't want that, that's why we create the same custom labels in the invoice, but I want that those three labels just link themselves with the client info so I don't have to type them again when creating the invoice.

Thanks for your help. Really appreciate it.
