An instruction file execution device which includes a receiver, a comparison section and a job execution section. The receiver receives an instruction file and a usable money amount, which instruction file describes a job flow which defines linking of a number of jobs. The comparison section compares an execution charge of a job being handled of the jobs of the instruction file received by the receiver with the usable money amount received by the receiver. If the comparison section determines that the usable money amount is greater than or equal to the execution charge, the job execution section executes the job being handled.
