Why did I receive an invoice? I returned the equipment.
If the equipment is not returned by the end of the billing period, the customer will be billed for the next billing period. But if the equipment is returned during the next billing period, a credit memo will be generated based on the return date and prorated by the return date. Credit will be applied to the final invoice, and the net balance will be due.

For example, if the equipment was rented for a 1-month period on the 1st of July and arrives back to ATEC on the 3rd of August, the customer will be billed for 2 full months but will receive those remaining 28 days credited back to their account. This is also applicable to bi-weekly rates.

However, when renting equipment, the customer receives it for the entire period requested. We recommend keeping the equipment until close to the end of the billing period to confirm whether additional tests are required or if results need to be confirmed.
Can I pay my invoices online or call in to make a payment?
We cannot accept over the phone payments. Instead, make credit card payments by logging in to your atecorp.com account or pay as a guest.
Can my invoices be sent electronically?
Yes, please send an email address to billing@atecorp.com or call (800) 404-2832 to provide an email address.
When can I expect to receive my security deposit refunded?
Upon receiving the equipment, ATEC’s lab will inspect it and notify accounting to process the refund.
What are your payment terms?
Prepay via MasterCard, Visa, American Express, Discover, or a wire transfer. Net 30 terms may be granted upon credit approval, but require an ATEC credit application to be completed and submitted for approval. Submit an online credit application here.
Do I pay for shipping charges?
Yes. If you do not have an account established with the various shipping companies, ATEC will pre-pay the charges and add the amount to your invoice. However, please also let ATEC know your desired shipping speed.
Do I need an RMA to return rental equipment?
No, not to return rental equipment. An RMA is only required if you are returning equipment for service.
How do I return rental equipment?
All rental returns must be returned PREPAID by customer to:
Advanced Test Equipment
Attn: Receiving Department
10401 Roselle Street
San Diego, CA 92121

Learn how to receive and return your rental.
Do I have to pay sales tax?
Yes, unless the equipment is used for resale and a valid resale certificate is provided or a tax exempt form is submitted to ATEC.
Who can I speak with regarding an invoice I received?
Contact our billing specialist at (800) 404-2832 (select Option 4, then Option 3) or email billing@atecorp.com
What if I cancel my rental order?
A restocking fee applies when a customer enters into a rental agreement with ATEC and subsequently cancels the order. At minimum, a fee will be assessed for $150 or 25% of the rental rate, whichever is greater. ATEC will enforce a restocking fee when ATEC shares no fault in the cancellation.
