You can add a GoCardless button to your website, so that customers can click and authorise a new Direct Debit to you.
1. Log into your GoCardless dashboard
2. Go to the Customers tab
3. Click the Add Customers button in the top right of the page
4. Choose the Link option
5. Copy the link to paste into your website
Alternatively, you could add a plan link or paylink to your website instead. These links will also direct customers to complete an online authorisation but once done, the respective subscription or payment linked to it will be automatically setup.
Here you'll find images for buttons you could add to your site, simply right click to save one of the images below:
