The PayPal's eCheque feature allows your customer to transfer money directly from his bank account to your PayPal account. eCheques differ from Instant Bank Transfers, as they are not instant payments.
With eCheque payments, you will typically receive the funds seven to nine working days after payment has been initiated by your customer.
Please note the PayPal interface updates regularly - this was correct on 2015-01-30
You can refuse to accept eCheques from your PayPal account. Log into your PayPal account the home screen select 'Seller Preferences' (on the left) then 'Block Payments' then click "Update" where you will see a tick box under "Block the following payments" to block "pay with eCheques". Save your changes.
Please note you might need to change your account type to a (free) Business account to disable this option.
Ensure payment has been received through your paypal account prior to marking the payment verified.
