What is a Service Invoice?

A service invoice is a document delivered to a client from a contractor or business after providing labor in the form of consulting, advising, or providing actual labor. The invoice is to be served on the client as a demand for payment. The date when the total balance is due is commonly 15, 30, or 60 days for most businesses. If the client goes beyond the due date, late charges and/or interest may be applied per the service agreement. After payment is made, the invoice should be marked as paid and act as a receipt.

IRS Requirements

Due to IRS Requirements, an invoice must be kept on record for three (3) years from the tax year date or two (2) years from which the tax was paid, whichever is longer.

A service invoice can be used for any type of labor that is paid on an hourly basis or on a per-job basis. The most common types of services, where the laborer is acting as an independent contractor, are as follows:

  • Accounting/Bookkeeping
  • Cleaning
  • Consulting
  • Delivery
  • Financial
  • HVAC
  • Legal
  • Medical
  • Professional
  • Real Estate
  • Retail
  • Technology

How are Independent Contractors Paid?

There are three (3) ways to pay an independent contractor, per project, per gig, and per hour ($/hr).

1. Per Project

When a contractor is paid on a per-project basis, payment is made at the completion of the work. This is often due to other factors such as equipment, employees, and other costs.

  • For Example – This is common for construction projects, as the contractor will need to include costs of building materials, products, and internal labor costs.

2. Per Gig

In other situations, the independent contractor is paid on a per-task basis. This is common for jobs when it’s difficult to track the laborer’s efforts and base the pay on performance.

  • For Example – A writer that gets paid on a per article basis, or a graphic designer that’s paid on a per-image basis.

3. Per Hour ($/hr)

Being paid on a per hour basis due to their efforts. This is especially common when the employer is providing the equipment, space, and tools necessary for the individual to complete the job.

  • For Example – A person that hires a bookkeeper to go over the finances of the company.

Employee vs. Independent Contractor

The main difference between an employee and an independent contractor is that an employee gets certain guarantees, such as unemployment, medical insurance (in some cases), and time-off, whereas an independent contractor is “their own boss” and must withhold their own taxes from income. An employee:

  • Works pre-set hours on a mandated schedule.
  • May only be paid per hour ($/hr) or salary.
  • Receives paid benefits from the employer.
  • Not responsible for withholding income taxes.

An independent contractor:

  • Works on their own schedule.
  • May be paid per hour or per project/gig.
  • No Benefits from the employer.
  • Responsible for withholding income taxes.
