Payt does not send separate messages to customers to confirm receipt of their payment. This also applies to payments via direct debit and to individual instalments of a payment plan.
How can my customer view the payment status anyway?
Your customer can always view the current payment status of an invoice themselves via the online invoice portal checkinvoices.com.
How can I still send my customer a message confirming payment?
There are two ways to let your customers know a payment has been received, if they ask:
Automatically from your accounting package: if this functionality is available there, you could send an automatic message as soon as an invoice has been matched.
Manually from Payt: send a message to your customer confirming that the payment has been received.
