What it is

A home-based service where you handle repeat back-office work for a few business clients: data entry, scheduling, email sorting, invoice chasing and basic record keeping.

Your first three steps

  1. Pick two or three task types and a client group you understand, then set hourly and retainer prices after checking what similar providers charge
  2. Draft a simple service agreement covering scope, hours, payment terms and confidentiality, and have a local attorney or a trusted template source review it
  3. Contact five local small businesses and offer a paid one-month trial to show your work and collect a testimonial
Who pays

Small business owners, contractors, clinics, real estate offices and e-commerce sellers who are too busy for admin but not ready to hire an employee.

How it makes money

Monthly retainer for a set number of hours or a fixed task list, or an hourly rate for ad hoc work.

Skills that help
  • Accurate and organized
  • Comfortable with spreadsheets and common office software
  • Clear written communication
  • Reliable with deadlines
Watch out for
  • Check whether your city or county requires a business license or home occupation permit, and any HOA or lease rules
  • Consider general liability and professional liability (errors and omissions) insurance
  • Handling client data carries risk: use secure passwords and storage, and check any privacy rules that apply to your clients' industry
  • Contractor status: confirm with the IRS guidelines or an accountant that clients treat you as an independent business
  • Relying on one or two clients is risky, so spread your work
