How to Customize Squarespace Checkout (Make Buying Feel Effortless)

Yes you can customize your Squarespace checkout to match your brand, streamline sales, and boost buyer confidence.

Think about it: your visitor just made it through your homepage, fell in love with your product, clicked “Add to Cart”… and now lands on a generic checkout page that feels like it belongs to someone else. Oof.

That’s where custom checkout styling swoops in-because that final step should feel as smooth and on-brand as the rest of your site.

Squarespace doesn’t give you full checkout control (unless you’re on Commerce Advanced), but with a little creativity, you can still guide the experience like a pro.

Here’s How to Customize Squarespace Checkout Effectively:

1. Adjust Style Settings

Go to Design → Site Styles. Change fonts, colors, and button styling-they’ll carry into your checkout and keep things cohesive.

2. Set Up Custom Thank You Page

Under Commerce → Checkout, create a branded thank-you page with video, upsells, or special messages.

3. Add Custom Checkout Fields

In Commerce → Checkout → Custom Forms, add fields like “How did you hear about us?” or special instructions.

4. Add Logo and Branding

In Commerce → Checkout → Branding, upload your logo and set custom background or accent colors.

5. Use Custom Code (Advanced Only)

If you’re on Squarespace Advanced, you can use CSS or JavaScript injections to tweak layout and styling beyond defaults.

Conclusion: Go for A Custom Checkout

Customizing Squarespace checkout is about removing friction, reinforcing trust, and giving your buyer one final nudge that says, “You’re in the right place.” Even with a few platform limits, you can still make the final click feel like part of your brand story not a detour.

So now, when someone buys from you, they don’t just check out they feel welcomed, confident, and even excited. And that’s exactly how every transaction should feel.
