Rainex provides you with two types of dunning so that neither type of payment is left unchecked in case of non-payment from the customer on time.
So, to configure dunning, under Settings in the Configure tab, click on Dunning for payments
Please note that both types of dunning are enabled by default. You can always disable one or both of them. Change the settings as you see fit or leave the basic Rainex settings.
Auto-collection dunning
Set the number of days during which the debit attempts will continue.
Set the frequency of renewal attempts within the above period.
Select what happens to the subscription for an unsuccessful payment when the dunning period expires.
If the selected final action option allows, the subscription will automatically renew.
Non-auto-collection dunning
Set the period during which your customers will receive reminders to pay for your product.
Then set the frequency with which they will receive these reminders from you within the period set above.
Select from the drop-down list what happens to the subscription if the customer still fails to pay the invoice at the end of the dunning period.
Finally, decide if the subscription will automatically renew after the customer pays or if you would prefer to do it manually.
