Xero Integration - Do I select the Access PaySuite Payment Service for individual invoices?

When configuring your Xero Middleware settings, you're required to add Access PaySuite as a Payment Service as part of the set up.
​
You won't need to select this with each individual invoice you raise, including reoccurring invoices, unless you would like to include the Custom Payment URL as part of the invoice.
​
The Custom Payment URL is what links your customer to the online sign-up page in the Middleware, which on completion automatically sets up the Direct Debit within Access PaySuite DDCMS and auto-link the contract in the
Middleware.
