I paid a vendor and set up the payment through QB Online. The vendor never received the payment and yet the sync'd bank account shows a cleared transaction. Help.

I know how delays are painful, @smeany-blueplain.

I appreciate you for setting up a payment feature and reviewing the transaction status. I'm here to furnish you with some information about the payment processing time frame in QuickBooks Online. 

Depending on the payment type, it could take up to five banking days for your vendor to receive the payment. The standard payment timing for both ePayments and mailed checks are four banking days. Also, please note that payments over $5,000 will take more time to arrive.

If it's already beyond the lead time, I'd recommend contacting our Customer Care Team. They can further examine the main reason for the delay. Ensure to call them within business hours to ensure we can cater to your concern immediately.
