01Is it right for you?

A good fit if you like numbers, order and steady clients

Most small business owners would rather do anything than their books. As a bookkeeper you keep their records tidy every month, from home and on your own hours, and good clients stay with you for years.

You'll like it if

You enjoy detail and getting numbers to match
You like quiet, focused work at a desk
You want clients who pay you every month
You can keep private information private

Think twice if

You find spreadsheets and software a chore
You'd rather be out and about all day
Deadlines at month and year end stress you out
You want to give tax advice without a license

10Questions

Common questions

Do I need a license to be a bookkeeper in Maine?

In the US, there's usually no license for bookkeeping itself. You need a PTIN from the IRS only if you prepare tax returns for pay, and only licensed accountants can call themselves CPAs. Other countries have their own rules, shown above.

Do I need to be an accountant?

No. Bookkeepers record and organize the numbers; accountants and tax preparers use them for taxes and advice. You need to understand the basics and the software well, and know when to send a client to an accountant.

Can I start part-time?

Yes. Most monthly work can be done any time before a client's deadline, so many bookkeepers start with a few clients in the evenings or on weekends.

Should I charge by the hour or by the month?

Many bookkeepers use monthly packages for regular work, so clients know their costs, and charge by the hour for catch-up or one-off projects.

What software should I learn?

Learn what small businesses near you use most, often QuickBooks Online or Xero, and get comfortable with bank feeds, bills and reports.
