If the company's credit repair specialists identify errors on your credit reports, they dispute those errors on your behalf. A credit repair company handles everything from drafting letters to managing correspondence with credit reporting agencies, creditors and debt collectors. You might need to supply documentation to support disputes. Some credit repair companies also offer credit counseling and debt management to help clients improve and maintain credit standing.
Scoring models consider how much you owe and across how many different accounts. If you have debt across a large number of accounts, it may be beneficial to pay off some of the accounts, if you can. Paying down your debt is the goal of many who've accrued debt in the past, but even after you pay the balance down to zero, consider keeping that account open. Keeping paid-off accounts open can be a plus in your overall credit mix since they're aged accounts in good (paid-off) standing. You may also consider debt consolidation.
