Approve. A drop-in sheet where users say yes once — how much, at which stores. You get a token that can't spend a cent more. Approve →
Checkout. Paste a product link, get the real total, place the order — the same three calls at every store. When a step needs the user, Harbor tells you exactly what to ask. Checkout →
Orders. Every order in one place, with webhooks for shipping, delivery and returns. Orders →
Major retailers. Target, Best Buy and The Home Depot orders land on the user's own account — Harbor prepares them on the user's device, and the final tap is theirs. How it works →
Target, Best Buy, The Home Depot — orders prepared on the user's device, with their saved address and card.

everyone elseWooCommerce, Magento and custom stacks. Coming soon.
Users set a per-order limit and a confirm-above amount once. Harbor checks both against the real total before any order is placed.
At major retailers the order is prepared on the user's own device, and the final tap is always theirs.
Harbor never sees a store password or a card number. Payment stays with the store and the user's wallet.
