Shelf prices, recalculated every day
A retail chain was competing against rivals who changed prices by hand, once a week, looking at three or four stores. Nobody in the sector knew what was happening that same day to the price of a product across the rest of the country. Neither did they.
What we built
First, what nobody had: the price of every product, every day, in every supermarket in the country, store by store. On that base, demand forecasting and dynamic pricing — models that learn how people react to each price change and anticipate how much will sell next week. That forecast is what then drives demand planning: how much to order, when, and which store to send it to. And on top, something for whoever does the shopping: a bot you send your list to, and it tells you which store it is best to buy it at, what to replace whatever is missing with, and without sending you further than you are willing to go.
Why it was a threshold
By the time the rest of the sector started watching prices in real time, the client already had two years of its own history: it knew how people had responded to every change, while the others were only starting to find out. The advantage was never the tool that collects the prices — anyone can buy that. It was the archive, and the archive isn't for sale.
