Is this debt buying or factoring?

CollBox does not buy or factor debt. CollBox uses true, third-party contingency collections.

CollBox is a service geared towards helping accountants and small business owners collect overdue invoices by advancing them to an intelligently-selected collection agency. Typically the agency is compensated with a percentage of the amount they actually collect, making the arrangement risk-free, and returning the majority of the amount collected to the business it is owed to.
