The SD platform has the relevant sales and pricing data along with the proper feedback from each channel to create a functional repricing system based on sales rate, price, and cost. If this is not in the works or soon will be there is a need to have the system update the price fields from each channel automatically.
Companies that use 3rd part repricing engines do not always display the proper current "price" in SD. Amazon, eBay and Walmarts current price needs to be fed back into the SD platform not only on each sale but also into the products price fields.
It would be preferred to have a repricing engine in the SD platform. I can go into extensive detail as to its functionality based on current available data in SD with only a few minor tweeks to two data fields. From there is is a few new fields, a few formulas and a timer.
