+We recommend that you provide a login flow within your app iFrame so that you can choose your own authentication method. You can also provide an account registration flow in your iFrame to help merchants create a new tax provider account. Learn more about [designing the app UI](/docs/integrations/apps/guide/ui). An account login flow lets you capture basic authentication credentials from merchants.

+We also recommend that you [establish a connection](#establishing-a-connection) immediately after the merchant installs your app, and you authenticate the merchant's account credentials. Otherwise, your tax provider will not be displayed when merchants navigate to the **Settings > Setup > Tax** page in the control panel.

 * BigCommerce has shared the `provider_id` of the tax provider configuration with you through email after you [shared your tax provider details](#sharing-provider-details-with-bigcommerce).
 * You have [built a draft app](#building-the-app) that handles the OAuth flow during app installation.

 Before you can provide tax estimates, the merchant must choose which regions they want you to service. The control panel displays a list of countries and subdivisions that you support. 
 
 If you support document submission, the merchant can choose to select the **Submit Order Data** checkbox. This allows merchants to submit tax documents for supported transactions on their store.
