Switching to Rundoo

Switch from J3 POS

J3 POS is a traditional point-of-sale system, and building-material and supply stores increasingly want more than a register at the counter. Rundoo is the AI-first POS and ERP built specifically for supply, hardware, and lumber stores, with deep inventory, house charge accounts, and integrated payments in one place that you can reach from any browser.
