The maximum number of contracts that can be defined in your account is set the product tier you purchase. 

If you need to manage more contracts then you can upgrade to the next tier of at any time. Defined framework lots count towards your contract total. As an administrator you can check how many contracts and framework lots are defined and your maximum total on your administrator page.

Don't worry. We have built in powerful audit logging. Every change made to a contract is captured and logged on the audit tab. You can review this log or run a printable audit report. And remember, does not allow a user to delete contracts, they can only be marked for deletion
