Systems and methods are provided to generate tools to evaluate the probability of an account being actually used by a business rather than an individual. In one aspect, a computing apparatus includes: a data warehouse configured to store transaction data of accounts issued by a plurality of issuers; and at least one processor configured to calculate values of a first plurality of variables for each of the accounts using the transaction data of the accounts issued by the plurality of issuers. The accounts include business accounts and non-business accounts. The at least one processor is further configured to identify a second plurality of variables from the first plurality of variables for a classification model to distinguish, using the values and logistic regression, the business accounts from the non-business accounts.
