my father owns a couple of retail stores in the bay area and both are being operated on pen and paper. basically we have around 40 different vendors we purchase from all over the country. each week we get multiple shipments.
right now the way my father manages inventory is he has a list from each vendor and tries to just order what he knows to be best sellers. there is no real control of the inventory and customers are getting upset that we keep running out of product.
without spending a whole lot of $ on a POS and inventory management system what would you guys recommend we do to handle inventory, purchasing, receiving and sales?
are there books or articles i can read?
