Essentials: for a one-time fee of $69 and monthly fees of $69, you'll get the basics of a personal case advisor, personalized dispute options, and an online dispute manager for tracking everything you submit to the various bureaus, agencies, and so forth. You'll also get access to financial management tools to help you budget for savings and paying down your debts.
The Credit Pros have some indicators of a good reputation: an "A+" rating as an accredited business with the BBB, along with some positive customer comments. We also like that they offer a solid satisfaction/refund policy: you can cancel your service at any time, and you can get a full refund if they don't force the removal of any errors on your credit history within the first 90 days of your service.
Reducing your balances on credit cards and other revolving credit accounts is likely the better option to improve your credit utilization rate, and, subsequently, your credit scores. Consistently making on-time payments against your debt will also help you build a positive credit history, which can have additional benefits for your credit history and, by extension, your credit scores, too.
