Payment Process


Our AP Process starts when our vendors send invoices to our AP Email inbox and contain authorized Purchase Order numbers. Once received, we process into our accounting system and send through our approval process that may include our senior accountant, general manager, project managers and other T Diamond Bar approvers. Once an invoice has been fully approved, it enters the payment queue and is processed for payment based upon our terms of payment. Remittance of payment occurs via AvidXchange, a third party remittance processor that utilizes ACH, Virtual Credit Card and physical check options as determined by each vendor. Timing of receiving remittance is determined by method chosen by each vendor.
