Frequently Asked Questions (FAQ)

If the status of my invoice in the Invoice Payment Status Inquiry screen is Payment in Process, how long does the payment process take?

County policy specifies that vendor invoices be paid within 30 days of receipt for standard vendors and within 15 days of receipt for certified small business vendors. In many instances invoices are paid sooner. If there are special payment terms by agreement, those terms are adhered to. If discount terms apply, it is our practice to pay according to those terms and obtain discounts. Vendor invoices received with missing or incorrect purchase order numbers may be returned to sender, and invoices not adhering to purchase order terms and specifications may be short paid. Invoices containing all applicable information are paid within the 15 or 30-day standard more than 97% of the time.
