Abstract: An expense solutions architecture is provided, in which an improved approach is described for implementing an expense solution. Mobile devices are integrated into an expense solutions architecture so that expense-related data can be captured, created, entered, and/or edited on the mobile device. This permits the user to generate expense line entries more in alignment with the location/way that many expense are actually generated, e.g., while the user is away from the office computer.
