Which payment methods do you accept?
We accept all major credit cards, PayPal, Apple Pay, and Google Pay, and financing is available through Shop Pay in certain regions. See How to Buy a Z1 or Z2: Pricing, Lead Times, and Payment.
Can I change the card or payment method on my order?
Not once the order has been charged. For security, our payment processor does not allow a new payment method on a charged order. The only way to switch is to refund the order and charge it again, which adds processing fees. If you still want to switch, email info@zerno.co with your order number.
I did not get an order confirmation email
- Check your spam, junk, and promotions folders.
- Add zerno.co to your safe senders list so stage emails and tracking reach your inbox.
- Sign in to your Zerno account on zerno.co with the email you used at checkout. If your order shows there, it went through.
If you still cannot find it, email info@zerno.co with the name and email on the order and we will resend it.
I cannot sign in or checkout will not load
- Sign in with the same email you used when you ordered.
- Open zerno.co in a private or incognito window, or try a different browser.
- Clear your browser cache and cookies, then try again.
- Turn off ad blockers or VPNs for zerno.co while you check out.
Where do I check my order or change my shipping details?
In your Zerno account you can see your order status, update shipping details, and edit your order before it ships. See Editing Your Order Before It Ships and Where Is My Order? Build Stages, Stage Emails, and Dispatch Estimates.

We would love to hear it! Email info@zerno.co and we will share it with our engineering team.
