How acquirers use personal credit
Most acquirers run a personal credit check on the principal owners of a small business, typically anyone with 25 per cent or more ownership, because the owner usually signs a personal guarantee. The acquirer is not lending you money, but it is exposed to you: if customers dispute payments after settlement and the business cannot cover them, the acquirer takes the loss. Personal credit is one proxy for whether an owner meets obligations.
It is, however, only one proxy. Underwriters put more weight on the business model, the product's refund and chargeback profile, processing history, the website and terms, and whether the business has enough cash to absorb disputes. A strong processing history with low chargebacks can outweigh a mediocre score. A clean score cannot rescue a business with a 3 per cent chargeback ratio.
