Tenant constantly trouble with rent

[Jason Y.]

This is for Charlotte Nc.  I have a tenant who has not been able to make full payment since Nov 2019.  Tenant always owes a balance.  Makes small payments here and there but always has an outstanding balance.  What are the steps to collect full payment and to get balance to zero, as tenant always promises they will pay off balance next week, next week etc.

Can we start eviction process?  I don’t have experience with NC real estate laws.  Or can you only do that when they do not pay rent at all?
