Hi
Generally, CCS will use the outstanding balance that is listed on your CBS report to compute the outstanding amount and usually that is one to two months outdated. Do note that CCS does not want customers to "abuse" as DMP offers much lower interest than the prevailing market interest rate that Banks charge. As such, if your income - reasonable level of expenditure > Current minimum amount due to Banks, they may not accept the case as you will be able to pay off with certain level of discipline.
If your case is accepted, during the briefing session, they will make you go through the outstanding figures and to make changes, if difference in the current outstanding amount is <> $1k of the stated amount.
All the best!
