Never Run Out Again

Physical kanban cards signal low stock. Your buyer reviews requests and places the orders.

How Arda works, in three steps. The walkthrough plays and repeats automatically unless you prefer reduced motion. Pause it or use the timer bars below the captions to jump to any step. Step 1, scan any code: a phone held in one hand moves along a shop shelf and scans four items, each with a different kind of code. It reads the Arda Kanban card on a two-bin shelf of M8 hex bolts from McMaster-Carr, the Data Matrix on a bottle of tapping fluid from Grainger, the UPC on a box of nitrile gloves from Amazon, and the QR code on an M12 connector bag from Grainger. Each scan adds the item to the cart. Step 2, review: a tap on Cart sends all four scanned items to Arda's shopping cart, grouped by vendor. McMaster-Carr takes orders by email, Grainger by purchase order and Amazon online. Step 3, order: purchasing reviews each vendor’s items and chooses Order All. Arda writes the email to McMaster-Carr, fills in purchase order 4471 for Grainger with its payment and shipping terms, and fills the Amazon cart, ready to check out. Each vendor's group then shows Ordered and leaves the cart.

Before Arda, we held inventory levels at 25+ for most of our critical components. Now, we hold inventory levels at 5 and make 5x as many vehicles.
