SD Mayer’s Online Payment Portal System

Invoices will be sent to clients via email as usual but the emails will look slightly different and the payment link goes to our partner, Aiwyn (Anduin). With our secure portal, you can make a payment with, or without registering for a payment portal account. Learn more about how to register for an account or how to pay without an account.

Here are answers to some frequently asked questions

How do I know if I can pay my invoice online?

All invoices – electronic or paper – can be paid online. However, only electric invoices delivered on or after Sept. 1, 2022, can be viewed in PDF form in the portal.

What payment methods are accepted?

You can use a bank transfer or a credit card to pay your invoice. Please note that we do not take debit cards.

Does it cost anything extra to pay via the portal?

If you pay via a bank transfer, there is no fee. Payments made with a credit card will incur a 3% processing fee.

Do I have to set up an account?

Not necessarily. However, having an account gives you more convenience options, like recurring payments and stored payment methods. So we definitely recommend you set one up. Visit the Aiwyn support page for full instructions on setting up your account.

I’m having trouble using the portal. Where can I get help?

You can watch our instructional video or contact us using the form at the bottom of this page. We’re happy to help however we can!

Let’s Set Up Your Account

While you don’t need an account to make an individual portal payment, having one gives you a lot more options.

In addition to allowing for automated recurring payments and bank transfers, an account lets you view previous payments, save and use payment methods, and link multiple accounts to one user.
