Pricing Database

we need to build a database where by we can upload products sheets and pricing files from various buyers. When we get a supply request we can look interrogate the DB and populate the pricing for the supplier request. as different suppliers call the same product something slightly different (SKU / product description), we need the Dab and front end GUI to be able to apply some intelligence in the search function. Further APIs which can look at pricing offered on the web for similar products to validate market pricing is desirable
