Five jobs, starting with a reason on every category

A tool that says AI can mean anything from a suggested category to a finished month. Before you compare prices, compare the jobs.

Categorizing: choosing the account for each bank transaction. Every tool on the list does this; Accountable shows the reason and how sure it is on each row, and Kick has an expert review the result.
Matching to the bank: checking each account's balance against the statement. Puzzle Complete, Digits, Pilot, Accountable and Xero (Auto-reconcile is included on Growing) automate it; QuickBooks starts its reconciliation help on Plus.
Closing the month: locking the numbers once they match. Accountable prepares the close every night and hands you one batch to approve; Puzzle's AI Close drafts the work during the month; Pilot's AI closes books monthly.
Answering questions: asking what you spent on software last quarter. Digits, Accountable, Xero (JAX) and QuickBooks all answer in plain language; Accountable's answers cite the entries behind them.
Changing the books on request: telling an AI to recategorize every Figma charge. Accountable on Pro, Kick from Basic and Digits accept write requests from Claude or ChatGPT, and Puzzle's MCP writes only in an opt-in beta. Accountable logs each change under the agent's name and can undo it.

The first job, categorizing, in Accountable's demo books: the category, how sure the AI is and why, on every transaction.

Who does the work sets the price more than software

Who touches the books on each tool
Model	Tools	What you do	Typical price for 1 company
Software only	Accountable, Digits, Puzzle, Kick, QuickBooks, Xero	Answer the questions the AI cannot, approve the month, hand reports to your CPA	$0 to $149 a month
Software plus a reviewer	Kick (expert review), Puzzle Core with Expert Reviewed Bookkeeping at $171 a month for up to $10,000 of monthly expenses	Approve the reviewer's questions	$40 to $171 a month
Software plus a dedicated bookkeeper	Pilot Core, Zeni, QuickBooks Live	Answer your bookkeeper's questions; they keep the books	$494 to $719 a month on Zeni (billed annually); Pilot Essentials $99, Core by quote; QuickBooks Live is quoted by your monthly expenses

Zeni's Starter plan is $494 a month billed annually ($549 list) and its Growth plan is $719 ($799 list). Pilot Essentials is $99 a month for up to $100,000 of monthly expenses; Pilot doesn't publish Core's price. QuickBooks Live prices by your average monthly expenses and needs a QuickBooks Online subscription on top.

Worked example: what three companies cost over a year

For one founder with three companies, on list prices billed monthly in November 2026, with every extra company past 250 transactions a year: $2,040 a year on Digits Core, $2,124 on Xero Growing (3 × $59 a month), $2,376 on Accountable Pro ($1,980 a year, billed yearly), $2,400 on Kick Plus, $4,320 on Puzzle Complete (3 × $120) and $5,040 on QuickBooks Plus (3 × $140).

Xero Growing was $55 a company until September 30, 2026. Kick Plus is $100 a month for the first entity and $50 for each entity past 250 transactions a year, so it runs $1,200 to $2,400 a year. Digits Core is $100 + 2 × $35 = $170 a month once both extra companies pass 250 transactions a year. Puzzle's $4,320 assumes each company takes Complete.

The gap between Xero ($2,124) and QuickBooks Plus ($5,040) is $2,916 a year for the same three companies, and Digits Core is cheapest while the extra companies stay small. Price is not the whole answer, which is why the next section asks what you want the tool to do.

Choose in five questions

Step 1: How many companies do you run? Past two, per-company pricing (QuickBooks, Puzzle, Xero) adds up fastest; Digits, Kick and Accountable put several companies on one bill.
Step 2: Do you want a person or software? If you want a bookkeeper who is accountable for the books, compare Pilot, Zeni and QuickBooks Live. If you want software with a reviewer you answer to, compare Kick and Puzzle's expert-reviewed plan.
Step 3: Will an AI agent work in the books? If you use Claude or ChatGPT, check whether the connection can write, and whether you can see and undo what it changed.
Step 4: What does your CPA use? Ask before you buy. Every tool here exports a ledger, and moves between them are free at Accountable.
Step 5: What do you need beyond bookkeeping? Bill pay points to Digits or Zeni, tax filing to Pilot, payroll to Xero (from $36 a month plus $6 an employee, run by Gusto) or QuickBooks.

Questions founders ask

What is the best AI bookkeeping software for a startup?

For built-in bill pay and invoicing, Digits. For a founder who wants every AI change logged and undoable, statements across companies and a free plan, Accountable. For a person plus software, Pilot. For the lowest list price at three small companies, Digits Core or Kick Plus at $100 a month.

Is AI bookkeeping accurate enough to trust?

It is accurate enough when you can see why it chose each category and undo it. Puzzle claims up to 98% automated categorization and Digits publishes no rate, so ask any vendor how it shows its reasoning and how you undo a wrong answer.

Can AI replace a bookkeeper?

For categorizing, matching to the bank and preparing the close, yes. For tax filing, unusual transactions and judgment calls, name a CPA. Pilot and Zeni keep a person in the loop for that reason.

Is there free AI bookkeeping software?

Accountable Free covers one company and categorizes the first 100 transactions a month. Kick Free covers 250 transactions a year, and Mercury Books is free through 2026 and then $35 a month.

How much does AI bookkeeping software cost for three companies?

From $100 a month on Digits Core or Kick Plus, while the extra companies stay under 250 transactions a year, to $420 on QuickBooks Plus. Xero is $177 and Accountable is $198.

Every company on one bill, with the reason on every category

Accountable Pro covers 2 companies for $149 a month and each extra company is $49. Every transaction is categorized with its reason, every AI change can be undone, your bookkeeping stays up to date, and moving in from any tool on this list is free.
