General Information

The City’s general payment terms are net 30 days. The Accounts Payable section is responsible for processing vendor invoices and other remittances in a timely manner. The City issues checks twice a month after approval by the City Council, with payments mailed out after approval.
To determine if an invoice has been processed for payment, it is recommended that vendors contact the accounts payable section. If needed, they will coordinate with the department which procured the goods and/or services. All invoices must be first approved by individual department directors before being sent to the City Council for approval.
Maintaining an accurate vendor data base is an essential function of the finance office to ensure proper payments. To register to be a vendor with the City of Bonney Lake a W-9 form must be filled out and filed with the Accounts Payable Department.
The invoice must indicate the purchase order number, the designated department and should be only for goods delivered or services rendered. Do not combine two or more orders on one invoice. The City will pay on partial shipments if invoiced.
All shipping costs are to be born by the vendor or prepaid and added to the invoice. If a purchase order initiated the shipment, shipping tickets should include the purchase order number.
All invoices should be sent to the City of Bonney Lake accounts payable section. Do not send an invoice directly to the department which placed the order as doing so may delay your payment.
