Ask where the products are made and how they are shipped.
About the order
Ask how the quote was built, what is included and excluded and what assumptions were made. Ask how errors are handled and who corrects them.
Ask for a delivery plan that matches your schedule.
About the support

Good suppliers answer plainly and in writing.
About the paperwork
