When the credit limit is reached partial or credit sales can’t be done for those customers.
To set the credit limit Go to Contacts > Customers > Action > Edit > More Information > Credit Limit.

NOTE: Do not set the credit limit as 0 for having no credit limit.
Credit Limit = 0 (the credit for the customer is 0)
