Architecture: lead source field should be on a lead or on contact?
I have a client who started using Pipedrive before Leads Inbox became available. We used the "lead source" field on the contact, as it was logical that every contact is actually a more or less cold lead, and then they'd call the contact and potentially create a new deal.
I saw in some projects that "lead source" was used on a Lead object (so ultimately on the deal). I can't fully decide which one is better. From one side it's about reporting, from another it's about filtering, from the third it's about convenience, etc.
Anybody has thought it through?
