Schlumberger requires an original invoice (also referred to as a tax invoice). In some countries, invoices sent as PDF files via e-mail are considered original invoices. Schlumberger does not allow payment based on either pro forma invoices or statements. Invoices must meet Schlumberger requirements for payment.

Supplier for field location
If you are a Supplier for field locations (invoice based on SWPS order), please refer to the Supplier Information Kit.

Supplier for Engineering, Manufacturing and Sustaining Centers (EMS)
If you are a Supplier for the Engineering, Manufacturing and Sustaining Centers, only invoices based on MFGPro purchase orders are accepted. These invoices should contain

  • MFGPro purchase order number (8 digits, alphanumeric)
  • full name of the Schlumberger employee ordering the goods or services
  • name and address of the Schlumberger business unit delivery point
  • Schlumberger cost center number (5-10 numerals)
  • reference or description of the invoiced item or service as stated on the purchase order
  • invoiced price, which must equal purchase order price.

International custom regulations require that duty be paid on the true net value of imported goods. Therefore, charges such as packing, freight, and handling must be itemized separately on all invoices submitted for payment.

Invoices for all purchases requiring purchase orders must be accompanied by a copy of the purchase order and confirmed goods receipt. The invoice price must match both the purchase order price and the confirmed goods receipt. Discrepancies will delay payment until the documentation is reconciled.

When the shipping address differs from the invoicing address on the purchase order, providing proof of delivery with the invoice is recommended.
