What it is

You run payroll for small employers such as restaurants, salons, contractors and offices. That means calculating pay, withholding and deductions, issuing pay stubs, and handling payroll tax filings, usually using professional payroll software.

Your first three steps

  1. Learn payroll basics through a course or the IRS employer resources, then pick payroll software that supports multiple clients
  2. Set up your business (sole proprietorship or LLC), get an EIN and price a simple package per employee
  3. Approach local bookkeepers, accountants and business owners and offer to take on one or two pilot clients
Who pays

Small business owners with a handful of employees who want payroll off their plate, plus startups that have just made their first hire.

How it makes money

A monthly base fee plus a per-employee fee per pay run. Extras like new-hire setup, year-end W-2 and 1099 filing, and catch-up cleanups can be billed separately.
