Back in 2020, managing items was difficult for SumUp merchants. We had 3 individual and disconnected item catalogs for POS Lite, Online Store and Invoices. First, users had to enable "Items" in the mobile settings, then they had to manage them in Checkout. To make things worse, we lacked common features like Inventory, Discounts, and Tax Management. Our experience to set items up took 2x or 3x longer compared to competitor solutions.
