Invoicing Best Practices

Regardless of the invoice option you select, ensure your invoices get processed by including the following:

  • Invoice number must be unique, minimum of 4 digits in length, and not contain any special characters such as: / - _ # %, etc. If an adjustment is made to an existing invoice, the new invoice must contain a different invoice number.
  • Invoice Date
  • Bill to Name
  • Bill to Address
  • Payment terms – as defined in our purchase order
  • PO Number is required, must be 8 alpha-numeric characters, and start with “9”.
  • Item: Purchase order line item number, description of goods/services, catalog/part number, unit price, quantity, and extended price should be an ­exact match to the purchase order
  • Tax, Freight, and additional charges must be listed separately.
  • Invoice total

In order to facilitate smooth processing of electronic invoices, please adhere to these guidelines. Failure to comply can delay payment.

  • Invoice number, invoice date, and purchase order number are required data elements for every invoice. Without this information, invoices cannot be processed and will be returned to the supplier.
  • Signs of all dollar amounts must be the same. For example, all line items must be (+) or (-).
  • If the PO line item number is not an exact match, there will be a delay in processing.
  • Freight should not be listed as a line item. It should be itemized with the additional charges.
