When servicing a piano for a piano dealership (or large school district) who requests invoices be sent once a month, here is how we recommend structuring the invoice.

At the beginning of the month create a draft invoice and add pianos to it as you service them throughout the month. At the beginning of each item description simply input the date of service for that item (See image below). Then at the end of the billing cycle send them the invoice requesting payment.
