(1) An electronic image of receipt or other IRS-compliant documentation is also acceptable
(2) This address accepts & signs certified deliveries from contract carriers
(3) When mailing payment is the only option, ase/edi prefer contract carrier delivery versus US postal service. There have been numerous delivery issues associated with regular mail delivery to this ZIP code. This method has proven unreliable, so ase agrees to pay for delivery of invoice payments which can only be made via physical check delivery.
(4) "Engineering Design Innovations, LLC" is also acceptable. Do NOT make check payable to "ASE" nor "Nick Merchant"
