A system and method for evaluating financial transactions, which may involve credit requests, is provided. Credit requests are categorized into three tiers: the third-tier is for requests capable of being processed by computers, the second-tier is for requests that meet predefined criteria and cannot be categorized as third-tier requests, and the first-tier is for requests that cannot be categorized as second-tier or third-tier requests. The first-tier requests are manually reviewed by a credit executive. The second-tier requests are delegated to more junior credit personnel via an inventive pre-approval procedure. The third-tier requests are processed, at least in part, by computers. Additionally, requests that exceed a credit line, or limit, may be approved by reallocating credit from other credit lines.
