Why did an ACH Debit InstaLink fail after the client authorised it?

Authorisation does not mean the bank has collected the money. Insufficient funds in the payer’s bank account can cause an ACH Debit payment to fail after verification. In that case, a later notification says the payment failed and no money was collected.

Ask the client to check the failure with their bank and make sure the funding problem is resolved. Check the latest Skydo status before treating the invoice as unpaid or arranging a new attempt. If the payer sees a debit that conflicts with the failure notice, send both records to support@skydo.com for investigation. Do not rely on the first authorisation email as proof of payment.
