Good day, Sarfz.
I'm here to share some steps to help you be able to collect payments. Let's make sure to set up the GoCardless app and configure the settings by following the steps in this article: GoCardless Welcome Guide.
Once you have completed the setup, you'll then be able to import mandates by following the steps below:
- Go to the Gear > Lists > All Lists.
- Click Import mandates.
