Register a Plumsail Account

Plumsail Forms product uses our service called Plumsail Account. Using Plumsail Account you can manage your susbcriptions — for both Modern SharePoint and Public Web Forms, and it also stores all your Public Web Forms.

You can register by filling out Plumsail Account registration form.

Sign in to an existing account

You can log in by going to the Plumsail Account login page and entering your login and password. Make sure you’ve registered first.

Bind your SharePoint tenant to your Account

In order to bind your SharePoint tenant to Plumsail account, you need to be logged in to Office 365.


This is only necessary for installation and we are not storing or using your credentials in any way, only to get permission for the installation.

Once you sign in to Plumsail Account, you’ll need to go to Forms section.

Plumsail Account

Select Subscriptions tab and click Add tenant to add your SharePoint domain.

Forms Licenses


SharePoint forms require custom scripts to be enabled to function properly. We recommend to grant permissions to the app, so it can enable scripting capabilities for you — you’ll need a tenant administrator account for that. Alternatively, you can enable scripting capabilities manually.

Once you’ve added SharePoint domain to your Plumsail Account, you need to install app package to your tenant.

Domain Added

Install app package to your tenant

Next, you need to add the Plumsail Forms app from Microsoft AppSource to the App catalog and enable it for all sites within your organization:

Download package

Once the application is added and distributed to all sites and the SharePoint domain is added to the Subscription section of your Plumsail account, you can use Designer to create modern forms for any list or library in your domain.

There are no downsides to distributing the app to all sites — it simply gives you an ability to replace any form, but it won’t replace any forms that you haven’t edited and saved yourself. If you change your mind about a particular form, you can always reset it to default as well.

Download designer and start designing forms for SharePoint

Once you’ve added your SharePoint domain to your Plumsail Account and distributed app across your sites using App Catalog, it is time to download the designer and start using it. You can download the designer app the installer from the Home tab of your Plumsail Account.
