When processing orders, you might come across the error "System.ServiceModel.FaultException: System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: Invalid BillTo account Number for the user
at DayRossGroup" error. 

This error could relate to one of two issues:

1) A misconfiguration of the Billing Account of the Client you're trying to process the order for, which might be missing or have the wrong billing account number; if that's the case, follow the solution on this article

2) The Billing Account number you're using is correct, but if you're trying to bill a 3rd party, your account is not authorized to bill the 3rd party account; if that's the case, reach Sameday (Day&Ross) support
