I'll help you set up an activate the feature to let customers pay the invoices online, wbceston-hotmail.

You also have two options you can choose from. First is by accepting card payments through PayPal and the second one is by Direct Debit with Go Cardless. Here's how:

1. Open an invoice or click the the + New button, then select Invoice. 
2. Go to the Payment options section, just beside Customer email.
3. Select between Accept Card Payments or Set up Direct Debit. 
4. Follow the onscreen instructions to fully activate the product and enter your banking details.
