A Direct Debit did not go through. Banks bounce collections for ordinary reasons, and it is usually sorted in a week.
This is a member paying your club. Your club's own plan with us is a different thing, and it fails separately.
What the member sees
They are told, by email, that their Direct Debit did not go through. It names the club and the amount.
They are not chased and they are not locked out of anything.
What you see
Their subscription goes to failed, and their name shows it on the register.
Payment failed is one of the filters on your members, so you can see everybody in that state at once rather than reading down the list.
They still count as owing. The figures treat a failed collection as money not in, which is what it is.
What to do
Nothing, for a day or two. Most of these are a bank holding a payment for a reason the member already knows about.
After that, have a word. The two common causes are no money in the account on the day, and a Direct Debit the member cancelled at their bank without telling anyone.
If the Direct Debit itself has gone, their renewal link offers them a fresh one. Send it and they set it up again in a minute. See Renewals.
If they would rather pay another way, take the money and record it. Recording cash and bank transfers is that job.
A payment that was taken and then reversed
This is different, and rarer. The money left their account, then came back out of the club's.
The subscription stops counting as paid, because it is not. Treat it as an unpaid one and start again.
