Solution 1Recommended

Contact the Invoice Issuer for a Replacement

Reach out directly to the organization that processed your payment to confirm your VAT number and request a new tax invoice.

If your VAT number or tax invoice number was not captured during the initial checkout process, the billing system may have generated a standard receipt instead of a full tax invoice. The issuing organization has the necessary records to generate a corrected document.

1
Identify the payment processor

Check your purchase confirmation email or bank statement to find the exact name of the company or payment gateway that processed your order.

2
Prepare your transaction details

Note down your order number, the exact date of purchase, and the email address associated with your account.

3
Contact customer support

Reach out to the organization's billing or support team, provide your transaction details, and explicitly request a replacement tax invoice that includes your VAT number.

Frequently Asked Questions

What is a VAT number?

A Value Added Tax (VAT) number is a unique identifier assigned to businesses for tax purposes. It is often legally required to be displayed on official tax invoices for business-to-business transactions.

Why is my VAT number missing from my purchase receipt?

A VAT number typically only appears on an invoice if you entered your company details and VAT ID during the checkout process. If left blank, standard billing receipts are issued without this information.

Can I add my VAT number after the purchase is complete?

In many cases, yes. You will need to contact the vendor or payment processor's support team with your order details and request them to reissue the invoice with your VAT number included.

Where can I find my WPS Office purchase invoices?

If you purchased a WPS Office subscription, you can usually find your invoice by checking your registered email for the payment confirmation, or by logging into the WPS Subscription management page to download your billing records.
