Lockbox Remittance Processing

Our Lockbox Remittance Processing service is designed to accelerate the receipt and deposit of check and credit card payments sent through the mail. This cash flow improvement solution collects customer payments at a centralized post office box rather than your business address, which reduces fraud risks and postal delays associated with mail delivery and in-house processing.

Payment processing is done by First Interstate Bank, helping ensure your payments are quickly received and directly deposited into your business bank account. Speak with one of our experienced business bankers for more information and how to sign up.
