To connect your FERMÀT funnels to a custom domain, you’ll need access to your DNS provider and the ability to configure a CNAME record.
Depending on when you onboarded with FERMÀT, a custom subdomain may have already been created for you as part of onboarding.
What's in this guide:
Choose Your Subdomain
Your FERMÀT funnels will live on a subdomain of your existing brand domain.
For example:
store.fermatcommerce.com(where we host all our own swag)
Make sure the subdomain you choose is not already being used elsewhere on your website or for other services.
Log into FERMÀT
Navigate to Settings → Domains
Choose a subdomain where your FERMÀT Shops will be hosted (this is where all your funnels will live)
You can pick from popular formats like:
shop.yourbrand.com
try.yourbrand.com
get.yourbrand.com
or enter your own custom subdomain.
Important: Once you choose a subdomain, it cannot be changed later.
Configure your DNS
To complete this step, you’ll need access to your DNS provider, typically the same platform where your domain was purchased (e.g., GoDaddy, Cloudflare, Shopify).
If you don’t have access, connect with someone on your team who does.
You’ll be adding a CNAME record that points your new subdomain to FERMÀT.
Add a CNAME record with the following details:
Type:CNAMEName:your subdomain (e.g., shop, try, get)Value:cname.fermat.shop
Reminder: The Name should exactly match the subdomain you selected in the previous step.
Step-by-Step Setup

Click Add record

Add a CNAME Record to Your Domain Registrar
The process for adding a new DNS record can vary depending on where your domain is hosted. To make it easier, we’ve included documentation links for the most common providers below.
Simply log in to your registrar and follow their instructions to add a new CNAME record and connect your subdomain.
Cloudfare Set Up
Log in to your Cloudflare account
Navigate to the DNS tab
Click Add record
Use the following configuration:
Type:CNAMEName:shop (or whatever subdomain you selected, like try, get, etc.)Value:cname.fermat.shop
Set Proxy status to DNS only
Click Save
Once you save the subdomain should connect within 10 minutes but can take up to 24 hours. If your subdomain is still not connected after 24 hours please contact [email protected] for additional assistance.
