Why invoices show paid before we actually get the money from the client by using GoCardless?

Thanks for joining us here on the Community mohamed6,

We'll automatically mark the invoice as paid on the invoice due date however it may take 3-5 days from this date for this payment to be processed and appear in your bank.
