This handy program allows you to both prepare estimates and work orders, and print invoices from a single screen. Estimates and work orders are stored for future use so they can easily be retrieved and reviewed. These can then either be printed as an invoice or updated. The application automatically calculate inventory and service pricing, as well as the final total of the invoice. This saves time from having to manually calculate the invoice and prevents calculation errors. The inventory is automatically adjusted to reflect the parts used for each invoice. A special "link" function assists in the preparation of the invoice and work orders further reducing the processing time.
