TL;DRA link on the invoice that lets the customer pay by card or bank through a connected processor.
A connected Stripe or Razorpay account puts a pay-now link on invoice emails. The processor's webhook marks the invoice paid the moment the charge succeeds, which stops Watchtower.
The processor is not the bank. Payouts arrive later, batched and net of fees, so bank reconciliation still matters even when every invoice was paid by link.
