Do you need a bookkeeper or a CPA for your startup?

You need both jobs done: monthly books, which software or an AI bookkeeper can cover while you are small, and a CPA to sign the tax return. Pilot starts at $99 a month, Zeni at $549, and a C-corporation return at $2,450 to $2,499 a year.

One C corp's books on Accountable Pro and its return cost $3,940 a year

Starting list prices for one Delaware C corporation, checked Sep 30, 2026, with every bookkeeping price billed annually and the same $2,450 CPA return (Pilot's starting C-corporation price) in each total. Pro is the plan that writes and closes the month; Free costs $0. Volume, entities and added services raise each total.

The short version

  • A bookkeeper records and reconciles transactions every month, while a CPA advises on tax and prepares and signs the return.
  • Pilot's Essentials plan is $99 a month for AI bookkeeping only, with tax and CFO help sold separately; Core, from $299 a month billed annually, adds a dedicated bookkeeper.
  • Zeni's AI bookkeeping with a finance team starts at $549 a month, or $494 a month billed annually.
  • Startup tax returns start at about $1,000 a year for a single-member LLC and $2,450 to $2,499 a year for a C corporation, before extra state filings.
  • Until you have payroll, investors, contractors or several entities, accounting software plus a CPA at year end is usually enough.

A bookkeeper keeps the record; a CPA signs 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.

Accountable keeps the record, and your CPA gets a free seat to sign the return

Accountant seats are free on every plan, so the CPA works from the books instead of a spreadsheet. Accountable Free covers one company and its first 100 transactions a month; Pro is $149 a month for 2. The CPA's own fee for the return is separate.

Bookkeeping starts at $99 a month, returns at about $1,000

Three ways to cover a seed-stage C corporation's year

For two founders, no employees and one Delaware C corporation, software plus a CPA is Accountable Pro at $1,490 a year plus a return from $2,450, or $3,940. Pilot Core is $299 a month × 12 plus a return from $2,450, or $6,038. Zeni Starter is $494 a month × 12 plus the same $2,450 return, or $8,378 (Zeni's own return starts at $2,499). Each is a starting price, and 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.

Software and a year-end CPA suit one simple company

  • 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

  1. Step 1: Who does the work, a person or software, and who reviews it?

  2. Step 2: Is the price per month fixed, and what raises it: transactions, entities, payroll or speed?

  3. Step 3: Do you keep access to your books and can you export everything if you leave?

  4. Step 4: When do I get each month's reports, and what happens if the books do not reconcile?

  5. Step 5: Who signs the tax return, and what is the fee for extensions, state filings and amendments?

  6. Step 6: What are the credentials of the preparer? The IRS has a directory of preparers with credentials for checking.
