What happens when the Lead/Target/Account limit is reached on 1CRM Startup or Startup+ Edition?

When you try to save Account number 301, or Contact/Lead/Target number 751 for example, you will get a message that the capacity limit has been reached, and the Save will not work.

To add more, you will have to upgrade your 1CRM. It is not recommended to delete contacts, as 1CRM is more powerful when it includes your past, as well as your present and future.
