Add Invoice

The AddInvoice requests performs a credit check of the customer, and if approved, adds the invoice. Otherwise an error message is returned.

Unless using the GetAddress/GetCompanyInformation method (only available in Sweden), this is the first step in creating an invoice.

This method will return the Invoice number (InvoiceNumber) which should be stored and used when handling the order/invoice later (e.g. CreditInvoice, PartCreditInvoice, AdjustInvoice, CancelInvoice etc).

The created invoice then needs to be activated through the ActivateInvoice or PartActivateInvoice (The invoice can also be auto activated directly in the AddInvoice request, if the package is sent directly when ordered).

The functionality Campaign Products, included in the AddInvoice request, allows you to customize and set up campaigns for your customers with special conditions of sale, e.g. campaigns with longer payment time, different invoice fees or specific transaction costs. To use this functionality, an agreement with Walley must be made.

This method is available in the following countries:
