The drywall repair invoice is an invoice used by an independent drywall contractor or a drywall company to bill a customer for services completed. Depending on the size of the job, drywall services can range from a few hundred to thousands of dollars. A drywall invoice will include a break down of labor (the number of crew members and their hourly wage) and a list of all materials used (mud, gyprock, tape, bead, etc.). All the costs are tallied up and a grand total is written at the bottom of the invoice along with any applicable taxes. Payment is due on or before the payment due date marked on the invoice.
