How it works
How the InfiPlex Square integration works
Square already keeps in-person and Square Online sales in sync with each other — InfiPlex extends that same real-time accuracy out to every other channel you sell on. A sale rung up at the register instantly adjusts what's available on Amazon and Walmart; a marketplace sale adjusts what your countertop system shows is in stock. Orders from every channel land in one queue, and shipments route through your warehouse or a 3PL with tracking posted back automatically.
