Does an unsigned attestation stop my tenants paying rent?
No. Rent collection, card payments and payouts all keep working. The monthly non-compliance fee is the only consequence.
From the guide Your Annual PCI Attestation.
What happens if it is not signed
Our payment processor charges a non-compliance fee for every 30-day period a form stays unsigned past its deadline, and that fee is passed on to your account. The current amount is shown on the attestation itself and on the fee schedule in your payment settings — it is $35.00 per 30 days at the time of writing.
Signing stops it immediately. Nothing is backdated, and no further fee applies once the form is on file.
Rent collection, card payments and payouts are not switched off by an unsigned attestation. Money keeps moving; the fee is the consequence.
