Manual purchasing is a drag, especially repetitive manual purchasing. Not only is it tedious, but it devours valuable time you could spend on other more pressing matters. Vendor managed inventory (VMI) programs can streamline the tedious purchasing process for small class-c parts like fasteners by automatically replenishing stock so you never have to place a new order anytime inventory runs low. This has the added benefit of saving time and money on purchasing orders that can be invested elsewhere in the business.
