You place Ordentic orders on the website.
Add products to your cart, then open it at https://ordentic.com/en/cart. Select a shipping address there, then continue to checkout. At checkout you confirm shipping and billing addresses, optionally add an order reference or store credit, choose a payment method, and pay. After you pay, you land on an order success page, and you can open your orders at https://ordentic.com/en/user/orders.
Some integrations can add items to your cart. You still check out on the website. There is no separate buyer path to place an order by API, email, or import.
You can order from several suppliers in one checkout and pay Ordentic once. In the cart, price optimization helps you find a strong combination of suppliers, for example cheapest or fewest deliveries. After you pay, you get one order with a section per supplier. Each supplier ships their own part.
