This may get confusing...We signed a lump sum contract with a customer for a project on Indian tribal land. (Kaw Nation of Ponca City Oklahoma) We shipped all material and it was signed for by our customer. The tribe is now requesting that we label invoices to them and not our customer. I understand being on tribal land we have no mechanic lien rights anyway but are there any legal ramifications in changing the bill to name and address from our customer to the Tribal information? They are not a customer of ours but I have sent a credit application to have some sort of information on them. If you need to call feel free 817-585-6024 Wendy Hilton
