For Walley B2B Invoice payments Dintero Checkout Express will use Walleys own business registry to fetch shipping and billing information about the customers company. It is important that the session is created without a complete company address, as the checkout then skips the company lookup . The `session.order.shipping_address.country` and `session.order.shipping_address.organization_number` can be set to prefill those values in the company lookup form. See the [Dintero Checkout Express documentation](/docs/checkout/express) for more information on how to implement this. ### Liability Unlike card-based payments, Walley B2B invoice payments do not reserve or guarantee funds at the time of authorization. A captured transaction means Walley has issued an invoice to the customer's company, but the customer still needs to pay it via their bank. Funds are not guaranteed to arrive in the merchant's account until Walley has collected payment and settled it. If the customer does not pay, the merchant's receipt of funds depends on Walley's collection process and the specific contract terms.
