Good reasons to use a proper form instead of a plain payment link:

• Customers can choose their own amount or how often they pay, which a fixed link can’t offer.
• A form can collect other things at the same time — marketing consent, Gift Aid declarations, delivery details — instead of just taking the payment and nothing else.
• With a link, the whole thing happens on GoCardless’s generic page, not yours — a form keeps customers on your own branded site, and only hands off to GoCardless for the bank details step itself.
• Forms connect to the other tools you already use, like Mailchimp, so a sign-up can trigger the rest of your workflow automatically.
• All your customer and payment data lives in one place on your site, rather than scattered across separate links.
