Change billing details and VAT number
Keep the name, address and tax ID on your receipts and tax invoices up to date in Polar's billing portal, and set your billing email.
Pro or Max plan Updated 29 October 2026
Polar, the merchant of record for Mailyoto plans, holds your billing details. The name, address and tax ID on your receipts and tax invoices are the ones Polar has.
Before you start
- A Pro or Max subscription.
- Your company’s VAT number or other tax ID, if you want it on your tax invoices.
Where each detail comes from#
| Detail | Where you set it |
|---|---|
| Billing name and address | Polar’s checkout when you subscribe, then Polar’s billing portal |
| VAT number or other tax ID | Polar’s checkout or billing portal. Polar checks it |
| Sales tax or VAT rate | Polar works it out from your country |
| Billing email | Billing email on the Profile card in Account |
-
Open Polar’s billing portal#
Open Billing in the sidebar. On the Payment method card, select Open billing portal.
-
Change the details there#
Update your billing name, address or tax ID in the portal and save them.
Polar uses the new details for the payments that follow.
-
Set the billing email#
Back in Mailyoto, open Account. On the Profile card, type the address into Billing email, then select Save profile.
It defaults to your account email.
The Profile card’s other fields#
The Profile card also has Name or company, Address, Country and Tax ID. Polar’s checkout doesn’t receive them, and your receipts don’t print them. Change billing details in Polar’s portal instead.
Receipts already made#
Mailyoto makes each receipt the first time you download it, and keeps that copy. A receipt you have already downloaded keeps the details it was made with. New details show on later payments.
Polar refuses your VAT number
Polar checks each tax ID before it accepts it. Check the number and its country prefix, then enter it again in the portal.
