An e-commerce company is considering a technology upgrade that would significantly streamline its order fulfillment process. It has an existing order fulfillment process that is mostly manual; while it works, it is inefficient. Purchasing the technology upgrade would require an up- front investment of $575,000. It would have an annual operating and maintenance cost of $19,500, but would result in labor savings of $105,000 per year. The company is considering an 8 year investment horizon; at the end of this horizon, the technology upgrade will have a $18,000 salvage value. Assume that the company's MARR is 12% and compute the present worth of the technology upgrade. [Enter your answer with no dollar sign or comma.]
