A bookkeeper keeps the record and a CPA answers for the return
A bookkeeper records every transaction, categorizes it, reconciles each account to the bank and closes the month. That work is daily and mechanical, and it is the part software and AI handle well. A CPA is a licensed accountant who prepares your tax return, advises on tax choices such as entity type and deductions, and can represent you before the IRS.
The IRS says anyone who is paid to prepare a return must have a Preparer Tax Identification Number, and that certified public accountants, enrolled agents and attorneys all prepare returns with different levels of skill and representation rights. It also says to ask about fees upfront and never to sign a blank return. You need a CPA for the return whatever you pay for bookkeeping.

Three ways to cover one seed-stage C corporation for a year
Software and a CPA: Accountable Pro at $1,490 a year plus a C-corp return from $2,450 = $3,940 a year.
Bookkeeper with Pilot Core: $299 a month × 12 = $3,588 plus a return from $2,450 = $6,038 a year.
Finance team with Zeni Starter: $494 a month × 12 = $5,928 plus a return from $2,499 = $8,427 a year.
Each figure is a starting price. Volume, entities and added services raise the total.
The spread is the price of having a person on your books every month. Many founders pay for the person once outside investors, payroll or several entities arrive, and use software until then.
When software alone is enough, and when to add a person
- Software plus a CPA at year end is enough when you have one company, few or no employees, simple revenue and no outside investors asking for monthly reports.
- Add a bookkeeper when a month ends and you cannot explain the difference between your books and your bank, or when you stop having time to review the questions the software asks.
- Add a CPA earlier than year end when you form the company, choose a tax election, raise money, issue equity or hire your first employee.
- Add a fractional CFO when investors ask for forecasts, board reporting or a fundraising model.
A CPA is worth more when the books are clean. Hand over reconciled books and a tax package, and the hours you pay for go to advice instead of cleanup.
Six questions to ask before you hire either
Step 1: Who does the work, a person or software, and who reviews it?
Step 2: Is the price per month fixed, and what raises it: transactions, entities, payroll or speed?
Step 3: Do you keep access to your books and can you export everything if you leave?
Step 4: When do I get each month's reports, and what happens if the books do not reconcile?
Step 5: Who signs the tax return, and what is the fee for extensions, state filings and amendments?
Step 6: What are the credentials of the preparer? The IRS has a directory of preparers with credentials for checking.
