Tips on using Science Exchange for R&D services.

What are the standard payment terms?

The payment terms for each order are indicated on the PO, which is dependent upon the Requester’s affiliation. The net payment terms typically are 100% upon completion at either Net 30, Net 60, or Net 90.


  1. Requester submits Request for Quotation.
  2. Provider generates a Quote.
  3. Requester accepts the Quote.
  4. A Science Exchange PO is issued to the Provider once the order is approved and work can begin.
  5. Provider returns Deliverables to Requester and then marks the Order as completed on Science Exchange.
  6. Requester approves Deliverables by marking the order as completed on their end.
  7. Science Exchange issues payment to Provider per the terms indicated on the PO. You can download a copy of the PO from the Billing tab of your order page.
