1. Setting up your Squarespace website

The first step to creating your own client portal is to build a basic website on Squarespace. You don't need any technical skills. Think of it as piecing together LEGO blocks, but instead of plastic pieces, you're using pre-designed templates.

Squarespace offers a ton of different website templates for different industries and website types. In the case of this article, we’ll pretend like we run a marketing agency (because I actually do) and go with the Agaro website template.

2. Creating a ‘Sign up’ and ‘Log in’ button on your site

To start, let's talk about adding the essential sign up and sign in buttons to your website. It may appear to be a minor detail, yet these two components are essential for setting up an efficient customer entryway.

To do this, you'll need to first navigate to your Squarespace site editor, where you can make changes or insert new items.

Here are essential steps to add the buttons:

Click on the “EDIT” button in the top left corner of your site editor.
From there, add a ‘Sign up’ button link to your navigation bar.
Implement necessary link features to seamlessly integrate with your client portal.

3. Choosing a no-code client portal builder

With the surge of no-code solutions, creating a client portal has never been easier. Even without coding knowledge, platforms like Assembly offer an intuitive way to set up and manage your own client portal.

With Assembly, this means providing clients with access to services such as messaging, payments, file-sharing, and more within their personalized white-label portals.

4. Customizing your client portal experience

With Assembly, you have the power to change a bunch of things like how your sidebar looks, colors, logos, and analytics codes, even the name that shows up for your brand.

For this guide, we’ll stick to just customizing our website name, aka our "domain." To give your client portal an on-brand name for your Squarespace site, head over to your admin area and find “Settings” at the bottom left.

5. Connecting your client portal to Squarespace

Finally, this is the part where we make our Squarespace client portal come to life.

After setting your buttons, you will link them directly to your Assembly portal, ensuring users can navigate and sign up easily through your Squarespace site.
