Remember that business credit has rules too
Regulation B, which implements the Equal Credit Opportunity Act, applies to business credit as well as consumer credit. Regulation B § 1002.9 sets notification rules, and paragraph (a)(3) covers business credit applicants. For a business with gross revenues above $1 million in its preceding fiscal year, and for extensions of trade credit, it requires the creditor to notify the applicant within a reasonable time, orally or in writing, of the action taken. Businesses with revenues of $1 million or less follow different provisions. The official interpretation notes that a creditor may rely on the applicant's statement about revenue size.
I mention this not to interpret it for you but because it shapes the workflow. The system needs to record when an application became complete, what action was taken and when, and how the applicant was notified. Your counsel should define those requirements before anything is automated.
