My expertise would be my accounting and analytical skills. Reviewing invoices and ensuring what we are billed for is exactly what we get at the best cost as possible. It's always important to ensure our operation runs smoothly and to ensure that I run reports to use the data to construct spreadsheets to show what our main offender is so that it can be corrected and eliminated. One of my achievements included finding a way to measure our productivity as a whole department as well as individually which helped our efficiency increase.
