Sales/Invoicing
Use the Sales/Invoicing window to enter invoices for customers. All entries made here are posted to General Ledger, customer
records, and possibly job and inventory item records. You have the choice of applying transactions to Jobs through the distribution
list box.
You can also use this window to print an invoice for a customer and set up recurring invoices for customers. Sales/Invoicing allows
you to enter as many as 500 line items per invoice.
