City of Longmont offers payment via Check, Virtual Credit Card, and ACH/EFT.
If you are interested in Virtual Credit Card or ACH/EFT payments, please contact our Accounts Payable department for more information. Check is the default method of payment when registering through our Vendor Self Service portal.
Vendors wishing to receive an ACH/EFT payment must be able to dually verify the bank account that will receive funds with our banking provider. Individuals and sole proprietors are generally not eligible for ACH/EFT payments for this reason.
