Wise (Personal) accepts transfers from one Wise account to another, sent to your Wisetag. SellAuth has no connection to Wise and detects payments by reading the “Money received” emails Wise sends you. Once forwarding is set up, orders process automatically.
Wise’s Acceptable Use Policy says “You may not use your personal Wise account to receive business payments”, and Wise can limit or close accounts that break its rules. Read the policy before enabling this method, and keep a second payment method enabled so a restriction does not stop the shop taking payments.

​
The payment page

Buyers need their own Wise account. The payment page shows your Wisetag with a QR code and an Open in Wise button, the amount to send, and a reference to enter on the transfer. Wise cannot fill in the amount or reference from a link, so the buyer types them. Buyers see your account name in Wise when they send the payment.

​
Settings

Wisetag. Your Wisetag, with or without the @. Buyers send money to it, and the QR code on the payment page opens it. Wise e-mail. The e-mail address of your Wise account, where Wise sends your notifications. It must be the mailbox you forward from, since that is how forwarded mail is recognised. Buyers do not see it. Currency override. The invoice is billed in your shop’s currency by default. Choose another currency to convert the amount at checkout and ask buyers to send that one instead. Same-currency Wise transfers are free for most currencies, so a currency you already hold is usually the best choice. Additional information. Optional text shown on the payment page. Underpay percentage. A buyer sending from another currency can land slightly under the invoice, and exchange rates can move between the order and the payment. A payment within this percentage of the invoice total still completes the order. The default is 5%. Override references. SellAuth gives each buyer a reference to enter on the transfer so the payment can be matched to an invoice. You can replace the generated references with your own comma-separated list. If you supply fewer references than are needed, SellAuth combines them to produce more. Business plan only.

​
Set up email forwarding

Payments are not detected until this is done. The steps below are for Gmail, and other providers have the same features under different names.
1

Turn on Wise emails

In the Wise app, open Settings > Notifications > Notifications > Your transfers and balances and turn on email notifications. Keep your Wise language set to English, because SellAuth reads the English version of the email.
2

Add the forwarding address

In Gmail, open Settings > See all settings > Forwarding and POP/IMAP and click Add a forwarding address. Enter payments@sellauth.com.
3

Confirm the forwarding request

Gmail emails a confirmation to that address. SellAuth returns Gmail and Proton confirmations to you automatically. Check your spam folder if it does not appear, then click the link inside to confirm.
4

Create a filter

Back in Forwarding and POP/IMAP, create a filter. In the From field enter noreply@wise.com, and in the Subject field enter Money received. Click Create filter.
5

Forward matching mail

Tick Forward it to and choose payments@sellauth.com. Create the filter.
6

Fill in the method settings

Enter your Wisetag and the Wise e-mail you forward from, then save.
Include the subject in the filter, so only payment emails are forwarded and the rest of your Wise mail stays in your own inbox.
Forwarding has to be automatic. An email you forward by hand no longer looks like it came from Wise and is not matched.

​
Test it

Wise does not let you send money to yourself, so you need a second Wise account. Buy something cheap from your own shop and pay it from that account, entering the reference shown at checkout. The order should complete within a couple of minutes of the Wise email arriving. If it stays at Pending, the forwarded email is not arriving or could not be read.

​
Troubleshooting

Orders never process. Forwarding was never confirmed, the filter does not match, or Wise emails are turned off. Check that Gmail lists payments@sellauth.com as a confirmed forwarding address, that the filter uses noreply@wise.com and Money received, and that the Wise notification setting is on. The email address does not match. The Wise e-mail in the method settings must be the address Wise sends your notifications to. Some orders process, others do not. Check the amount and the reference on the payment. A payment whose reference is missing or does not match the order is not matched automatically, and has to be processed from the invoice page. Partial payments are added up, and the order completes once the total, after the underpay allowance, covers the invoice. A payment arrived a day or more after the order. References are matched for 25 hours after the order is created. A later payment has to be processed from the invoice page. Your Wise language is not English. Change it to English, and any new “Money received” emails can be read. Payments already emailed in another language have to be processed from the invoice page. Wise limited the account. This cannot be resolved from SellAuth. Enable another method, and see How to accept card payments.
