Invoice Policy

(Last Updated: 09.30.19)

Invoice Delivery

Invoices are emailed to clients. A shipping and handling charge will be added to each paper invoice for customers insisting on delivery via US mail.

Matching Test Results to Invoices

Lengthy sample descriptions seen on test result reports are cut to 30 characters on invoices. To match your invoice to your test results, locate the Order Number and/or Sample IDs on each. Sample IDs contain the date of testing. Example: Sample ID TLI-091619-947 was tested on September 16, 2019. We will make every effort to further identify samples, as needed.

Shelf Life Studies Invoices

Shelf Life Studies are billed on an ongoing basis, which means you may see several bills for the same Sample ID. In this case, you can further match testing by the Day in the description field on both test result reports and invoices.

Payments

Please inquire prior to paying off your entire Customer Account Balance to ensure the total has not changed from the date of this invoice. Negative balances indicate a credit on your account.

You may click the button on your email invoice to pay by credit card or bank transfer at your convenience. We also accept credit cards by phone or in person, cash, and checks.

If you would like to authorize Trelfa Labs, Inc. to run your credit card to pay for invoices, click the following link to fill out our Authorization Form. You can also download it from our Client Portal. Please email the completed form to rebecca@trelfalabs.com directly.

Receipts

  • Net 30: Receipts are not provided for most Net 30 payment transactions.
  • Pre-payments and Pre-Authorized Payments: You will be emailed a copy of your paid invoice as your receipt.
  • Detailed payment transaction receipts emailed upon request.

Account Inquiries
