MoonClerk has three ways to build a payment form. Modern puts every section on one page with a live checkout preview (this is the default for new accounts). Step by step walks you through the same six sections one at a time — Basics, Amount, Payment methods, Add-ons, Confirmation, and Organization — telling you which two are required before a form can take payments. Classic is the original single-page editor. Modern and Step by step can each do everything the other can; the difference is pacing, not capability. You can switch between them at any time.

The Modern builder — the whole form on one page:

And the same form built Step by step:

1) Click on the Account drop down menu and choose Settings.

2) Find the "Form builder" card near the top of the page. It shows which builder you're using; click one of the buttons on the right to switch to another.

3) Whichever builder you pick is what opens the next time you create or edit a payment form. Your forms themselves are unaffected — switching builders never changes a form's settings; it is a choice about how MoonClerk looks to you.
