The information on your invoice comes directly from your vendor/merchant (example: Texas Instruments). Apruve is a software company and does not store any tax information, nor do we have any control over the amounts depicted on the invoice. If tax was added to an invoice, it would have happened at the time of checkout for 4 reasons:
The merchant does not have a tax-exempt certificate on file.
The tax-exempt certificate on file has expired.
The tax exemption is only valid in certain states and the order was not shipped in the tax-exempt state.
There is an issue with the merchant’s system (for example, the company name does not match the certificate)
In all four instances, you will need to reach out directly to the merchant in order to resolve this issue.
It is important to make sure that your order does not have tax at the time of checkout, as the amount shown at checkout will be due according to the terms of sale with your merchant and subject to the terms of our service agreement.
As we can't update the invoice, we would advise making your payment and disputing it with your merchant. Some merchants may issue a return on the invoice (should they choose to do so) and your funds will be refunded.
