The DepositFix form builder lets you style your forms to match the look and feel of your website. Or, if you've already set the style of the form inside HubSpot, you can tell DepositFix to match the style of the HubSpot form instead.
The moment you publish the form, you'll be able to preview it by using the shared link option. This will also allow you to run a test payment, check the details and then see which payment information gets sent over to HubSpot.
