DECISION ENGINE

Examples of the present disclosure describe systems and methods related to a decision engine. In an example, proposals, work orders, invoices, and assets may be managed by the decision engine, such that recommendations may be generated and automatic actions may be performed on behalf of a subscriber. For example, a model may be trained based on historical data, which may be used to generate recommendations as to whether proposal should be approved or rejected. In examples, the proposal may be presented along with additional information, such as asset information or information relating to similar proposals, thereby enabling improved decision making. In other examples, invoice approval rules may be generated based on the historical information applied to invoices as they are received from contractors, which reduces the amount of manual effort involved in approving and rejecting invoices.
