Quick purchase order (PO) validation and invoice submission checklist

Do you have purchase order number?

Deliver goods and services and submit your invoice

Yes

Please reach out to GSK contact for purchase order number

No

Orders cannot be accepted without a purchase order (PO) number.
If the purchase order is exempt, include the GSK contact details when submitting the invoices.

Detailed invoicing requirements to ensure compliance and timely payment

Please include the following items within your invoices to ensure compliance and ensure on-time payments

  • Your name, address, and tax identification number
  • Provide GSK's single purchase order number (not multiple) unless the transaction is exempt
  • Add GSK's full legal and full address to the invoice
  • Use a clear and unique invoice number, and include the invoice date
  • Clearly itemise the goods or services you provided
  • Ensure invoice line items include a quantity, unit of measure, unit price, and match the details in GSK's purchase order
  • For invoices with a purchase order, make sure the unit of measure matches the purchase order line item's unit of measure
  • Clearly identify applicable taxes (VAT/SST/GST), freight/shipping, or other charges
  • Include both the net and gross amounts for the invoice
  • Submit your invoice to the country where the purchase order originated, even if that's different from where the invoice is to be paid
  • Make sure the invoice is billed to the correct GSK entity that made the purchase. You'll find this information in the footer section of the purchase order
  • Submit your invoice promptly—don't future-date it
  • Include your banking details for payment remittance directly on the invoice
  • If you're using a credit note, reference the original invoice number and, if applicable, the purchase order number
