Extending Zoho CRM's database - additional table/entity

Extending Zoho CRM's database - additional table/entity

Hi there

I would like to add a new table to CRM, containing what are in effect like financial transactions.  Each transaction would be linked to two accounts in CRM, one being the Supplier account and one being the Customer Account. 

I then need to see:
  • under each Supplier:  the transactions representing things they have sold
  • under each Customer:  the transactions representing the things they have bought
Is this possible in CRM alone, and/or can it be done by combining multiple Zoho applications such as CRM and Creator please?

On one hand we need that database to be useful for managing the transactions (so could use Creator), but on the other hand we also need to give the users some basic CRM capabilities. 

Thanks!
