Hi,
It can take several business days for your eCheck transfer to complete and the recipient can use the funds from your payment. Here are estimates based on which country your bank account is from.
U.S. - up to 4 business days
Canada - up to 8 business days
UK - up to 9 working days
Australia - 7-8 working days
Your eCheck payment does not appear in your recipient's balance until the transfer is complete.
