  1. bookkeeping license in Illinois: do you need one?

    No license to do bookkeeping. You may not call yourself a CPA or perform audits/attestation without a CPA license, and preparing tax returns for a fee requires an IRS PTIN. In Illinois, the state board or agency that handles bookkeeping licensing is linked below — check it, and your city or county business-license office, before you advertise or take a job. If Illinois doesn't license bookkeeping work at the state level, a local business license (and often liability insurance) is still expected.

  5. What to charge for bookkeeping in Illinois

    Monthly retainer by transaction volume and complexity — $300–$600 for a small service business, $600–$1,500 for a busier company, cleanup/catch-up billed separately. Value-based and per-account pricing beat hourly. Check what the established bookkeeping businesses in your city actually charge before you set your rates — pricing to undercut them is the fastest way to work the first year at a loss.

  6. Getting your first bookkeeping customers in Illinois

    Referrals from CPAs (who don't want the monthly work), local business groups, and a niche-focused site. Monthly retainers make this a highly predictable business. Niching by industry (restaurants, contractors, agencies) lets you templatize and raise rates. Recurring and extremely sticky — clients rarely switch bookkeepers if the work is accurate and on time. CPA referrals (they want the tax work, not the monthly grind) are the best acquisition channel.

  7. The mistake most first-year bookkeeping owners make

    Pricing hourly and competing with overseas rates. Package a monthly deliverable (reconciled books + a statements package by the 15th) at a flat fee, niche by industry, and you're selling an outcome, not time.
