Two settings that decide how you treat customers whose access is running out, or whose payment just failed.
Where
Go to Mollie Payments, then the Options tab, and find Subscription and expiry.
The plugin explains what these do: they control the daily check that warns customers before their access expires and handles failed recurring charges.
Warning email days override (all packages)
How many days before expiry your customer gets warned.
Leave it empty. This is our advice, and it is the plugin’s default.
Empty means the plugin uses smart defaults, which scale with the length of the package. A yearly package gets more warning than a weekly one, which is exactly what you would decide by hand.
The defaults are: no warning for packages of three days or less, one day for packages up to a week, two days up to three weeks, five days up to two months, and seven days for anything longer.
Fill it in only if you have a real reason to want the same number for everything.
A per-package setting beats this one. If you set a number in the Mollie Settings block on an individual package, that package ignores whatever is here.
So the order is: package setting, then this global setting, then the smart defaults.
Grace period after failed recurring charge
How long a customer keeps their access after a direct debit fails, while Mollie retries.
The plugin puts it plainly: days to keep access active while Mollie retries a failed automatic charge. After this period, access ends.
The default is 3 days.
What actually happens during those days
The charge fails. Your customer keeps their access and may not even notice. Mollie retries automatically, which often works, because a salary lands or an account is topped up.
If a retry succeeds, everything continues as though nothing happened.
If nothing succeeds by the end of the grace period, access ends and the subscription is cancelled, so no further attempts are made.
Should you change it?
Three days suits most businesses. Long enough for a bank retry to land, short enough that you are not giving service away.
Longer if your customers are businesses with slow accounting departments, or if losing one hurts.
Shorter only with a good reason. Cutting someone off the moment a payment bounces loses you customers over temporary bank problems, and most failed payments are exactly that.
