You can try to negotiate a pay-for-delete with the collectors in exchange for you paying off the debt. If you do this, make sure you get it in writing before making payment. Otherwise they might decide they don't need to hold up their end of the bargain, claiming they never agreed to delete anything.
If they won't do a PFD, you need to make sure you get it in writing that paying the discounted amount will satisfy the debt. If they send you something stating that, the balance should be reported as $0 and it can stay on the report for the remainder of the reporting period.
