The various embodiments herein each include at least one of systems, methods, and software for discrete-event simulation for transaction service point device cash servicing, such as SSTDs. Such embodiments provide a unique, completely different analytic approach, and predicts a more detailed set of intractable insights for efficient servicing cash needs of SSTDs. One example embodiment in the form of a method includes receiving cash state data from an SSTD into an SSTD cash state simulator and applying a set of simulated input demand sequence data to the cash state data to obtain outputs over a simulated period. This method, while executing tracks a simulated cash state of the SSTD from which the SSTD cash state data was received over the simulated period to identify SSTD servicing needs. The method then stores the identified SSTD servicing needs in an SSTD management module.
