A labor and materials invoice contains fields for recording both the hours and parts or products that were used during a job. The invoice is common for professions that involve construction, repairs, and installations.
When to Use the Invoice
Whether or not a company or freelancer should use a labor + material invoice is mainly dependent on if the client is expecting the material cost to be included in the labor charge. For example, hairdressers don’t charge clients for the cost of shampoo or conditioner—they only charge for the time dedicated to cutting hair.
Another means of determining if a material should be separated from labor is if the client will ultimately use it at a later date or it will continue to provide use/value for an extended length of time. For example, mechanics almost always (with the exception of routine service) charge parts separately to the labor dedicated to installing them.
As an overview, materials and labor should be separated individually if the following applies:
- The materials/products are expensive
- The product will be used for a considerable length of time
- The objects required to be purchased by the seller/provider are not routine (not factored into the labor cost)
