Once a check payment has been approved in MineralTree, your check is printed and mailed from a processing facility in North Carolina. Checks are sent via USPS First Class Mail and you can expect your vendor to receive your payment within 3-5 business days.
Checks are packaged in a windowed envelope, so the vendor will see clearly that this is a check payment. The envelope will have the check itself and a tear-off remittance stub with details about the bills being paid and any credits that were applied to them. Please find an image of an example check attached here.
