Describe how upselling is monitored via the Poppy Menu system.

The Poppy Menu system effectively monitors upselling by tracking commonly purchased complementary items. This approach enables businesses to identify patterns in customer purchases and highlights which items are often bought together. When staff are aware of these combinations, they can strategically present additional items to customers during their purchase process. This method is a practical and direct way to enhance the customer experience while increasing sales, as it focuses on the natural buying tendencies of customers. By utilizing this tracking system, businesses can tailor their upselling techniques to align with established buying behaviors, which fosters a more effective sales strategy.
