How accountants find new small-business clients

Why a business's first year is the best time to win it, where new businesses show up, and a first-year checklist owners will thank you for.

Published October 9, 2026

An established business rarely switches accountants. A new one hasn't picked one yet, and in its first year it faces decisions it can't easily undo: how it's taxed, how its books are set up, whether it's collecting sales tax. Reach the owner then, with something useful, and you're the accountant from day one.

What a new business has to sort out in year one

  • How it's taxed: an LLC is taxed as a sole proprietorship or partnership by default; electing S corporation treatment has deadlines, and missing them can cost a year.
  • An EIN and a business bank account: the basics that keep personal and business money apart.
  • Bookkeeping: a chart of accounts, receipts and a system before the shoebox fills up.
  • Sales tax: businesses selling taxable goods or services usually need a state sales tax permit before their first sale.
  • Estimated taxes: owners who don't have tax withheld generally pay quarterly estimates (mid-April, mid-June, mid-September and mid-January for individuals).
  • Payroll: the first hire brings withholding, unemployment registration and new-hire reporting.

Where new businesses show up

  • State business filings: every new corporation and LLC is registered with the state, with a filing date.
  • Licences: new contractor, food, liquor and salon licences point at businesses that are about to trade.
  • New clinics: health practices get a dated National Provider Identifier.
  • New carriers: trucking companies get a dated USDOT number.

In our database, the trades most likely to need help fast are the ones with the most moving parts: 1,232,659 clinics and health practices, 1,079,420 salons and personal-care businesses, 874,737 contractors and 857,008 restaurants and food businesses, many of them cash- and staff-heavy.

A first email that gets a reply

  • Offer the checklist, not the engagement: "Here are the five things most new LLCs miss in their first year" is worth reading even if they don't hire you.
  • Mention the deadline that matters to them: an S corporation election or the next estimated-tax date is concrete.
  • Specialise: "I work with new restaurants in Milwaukee" beats "full-service accounting".
  • Partner up: payroll providers, business bankers and insurance agents meet new owners too; trade referrals.

When to reach out

The weeks after a filing or licence, and again in the run-up to tax season (January to April), when new owners realise their first return is coming.
