Expect questions about your methods for approving and paying invoices. The hiring manager might ask, "Do you have experience creating, approving and paying invoices?" Or, "How do you handle conflicts with invoices?" A potential employer wants assurance that you are comfortable with the invoicing process and have ways to verify the authenticity and accuracy of each invoice. Detail the steps you take before approving an invoice, such as verifying vendor account numbers, double checking amounts owed and making sure funds are available to cover the expenses. If asked how you deal with incorrect invoices, provide an answer or a work-related example that demonstrates your ability to quickly and efficiently resolve conflicts.
