Tax exempt instruction

Depending on the order, sales tax may be calculated and charged. Any sales tax charged will be indicated once your billing and/or shipping address have been entered during checkout.

Tax-exempt entities can request a refund of the tax paid on an order. We will need a copy of your tax-exempt certificate and the billing or shipping address on the order must match the address on the certificate. Please include your order number or a copy of your receipt or invoice. You can email a copy of your certificate, with order number or invoice to

This email address is monitored 7days/week and a 24 hour response time should be expected. Once the proof of tax exemption has been received, our Customer Service team at Digital River (Authorized Reseller acting as Merchant of Record on behalf of VXi/BlueParrott®) will ensure that the correct amount is returned back to you.
