Repeat leadsRepeat leads is a good instrument if you have regular customers. When such a customer comes back to make another purchase, Bitrix24 creates a new lead with a link to the customer's contact automatically. This lead will be marked as "repeat".
How to work with regular customers without creating repeat leads
Sometimes you need to save the communication history of a customer without creating a new lead.
Just convert the lead into a contact to do that. Then disable the repeat sales mode in CRM settings (CRM > Settings > Other > Other settings).
Now the communication history will be saved to the customers' contact forms.
