Are AI assistants now choosing accounting software for small businesses?

Not on their own, but they increasingly shape the shortlist, both for business owners and for the accountants who advise them. A small business owner who asks ChatGPT which accounting software fits a two-person landscaping company gets a short list of names, and so may the bookkeeper who sets that business up. For an accounting software company, that answer now sits in front of a subscription worth years of recurring revenue.

The short version

  1. The prize is large and sticky: Xero reported 4.92 million customers paying an average of NZ$55.44 a month in fiscal 2026, with average monthly churn of 1.14%, and Intuit’s QuickBooks Online Accounting revenue grew 22 percent in fiscal 2025.
  2. Accountants are a second gatekeeper: more than 80% of mid-market QuickBooks Online customers work with an external firm, Intuit said at its 2025 investor day, and accountants in Intuit’s survey of 700 professionals use AI daily at nearly double the rate of small businesses (46% against 28%).
  3. Switching events create waves of new buyers: about 780,000 UK sole traders and landlords must use compatible software for Making Tax Digital from April 2026, and a further 970,000 from April 2027.
  4. Accounting buyers often pick wrong: in Capterra’s 2026 survey of buyers in the accounting profession, 44% ended up with software that disappointed, and around a third (36%) of purchases were followed by finding a better match.
  5. AI answers about this category are not neutral or fixed: in our country study, ChatGPT put QuickBooks first in the US and Canada and Xero first in the UK and Australia, and in our pricing study only 61.9% of software plan prices that four assistants quoted were fully faithful to the vendor’s page.

Who picks the books software, and how long does a subscriber stay?

Owners of very small businesses buy most of it, often with an accountant or bookkeeper choosing or approving the product.

The market is wide. The US Small Business Administration’s Office of Advocacy (opens in a new tab) counts 36.2 million small businesses in the United States, and almost every one of them has to keep books. Most accounting software is sold to them as a monthly subscription, often after a free trial, which makes the first choice unusually valuable.

The two leading cloud platforms show what a customer is worth. Xero’s fiscal 2026 results report 4.92 million customers, average revenue per customer of NZ$55.44 a month (up 23%), and average monthly churn of 1.14%. Xero puts the total lifetime value of its customers at NZ$21.0 billion. At Intuit, QuickBooks Online Accounting revenue grew 22 percent in fiscal 2025, driven by “higher effective prices, customer growth, and mix shift”, inside a business solutions group with $11.1 billion of revenue.

The buyer is rarely only the owner. According to a report on Intuit’s 2025 investor day (opens in a new tab), more than 80% of mid-market QuickBooks Online customers already work with external firms. Accountants and bookkeepers recommend a platform, set clients up on it and often move whole client books from one product to another. That gives accounting software two journeys to win: the owner’s and the advisor’s.

Where do AI assistants show up in that buying journey?

At both ends: owners ask AI assistants for recommendations, and accountants use AI tools daily in their own work.

On the owner side, the evidence is early and comes from small samples. A Revenued survey (opens in a new tab) of nearly 300 small business owners found over 90% using at least one AI tool by September 2025, and nearly 70% of those AI users relied on ChatGPT or other OpenAI models. Revenued sells financial products to small businesses and is not a research firm, so read this as a direction, not a measurement. Across all software categories, G2’s August 2025 survey (opens in a new tab) of more than 1,000 buyers found 87% saying AI chatbots are changing the way they research.

On the advisor side, the signal is stronger. Intuit’s 2025 Accountant Technology Survey of 700 US accounting professionals found 46% using AI daily, nearly double the 28% rate among small businesses, and 64% planning to invest in or upgrade AI over the next year. The people who recommend accounting software are among the heaviest AI users in the small business world.

Google is part of this too. An owner who types a bookkeeping software query into Google will usually see an AI Overview, the AI summary at the top of the results: in our study of 800 US searches, B2B software and technology keywords triggered one on 96.0% of searches, the highest of the eight industries we tested.

The platforms themselves are moving into the assistants. Intuit signed a multi-year contract worth more than $100 million (opens in a new tab) with OpenAI so that QuickBooks and its other apps can work inside ChatGPT, and Xero says it built a connector into Claude.ai. The category leaders are treating AI assistants as a place where customers will meet their products. For the wider software picture, see our B2B SaaS article.

What do owners and bookkeepers ask assistants about books software?

Fit-for-my-business questions, switching questions, compliance questions and price questions, usually with the business size or trade attached.

We wrote these prompts to mirror situations owners and accountants face, such as a new tax rule or a discontinued product; we did not observe them:

  • Fit: “What is the best accounting software for a cleaning business with five employees and job costing?”
  • Switching: “What should I move to now that I can’t buy a new QuickBooks Desktop Pro subscription?”
  • Compliance: “Which software is compatible with Making Tax Digital for a landlord with two properties?”
  • Integration: “Which accounting software connects best to Shopify and Stripe and handles sales tax?”
  • Outgrowing: “When should a $10 million distributor move off QuickBooks Online?”
  • Accountant-side: “Which platform makes it easiest to manage 60 bookkeeping clients?”

Several of these are driven by real events. Intuit stopped selling new subscriptions to QuickBooks Desktop Pro Plus, Premier Plus and Mac Plus in the US after September 30, 2024 (opens in a new tab), and encouraged accountants to move clients online. In the UK, HMRC (opens in a new tab) requires sole traders and landlords with qualifying income above £50,000 to keep digital records and use compatible software from April 2026, about 780,000 people, with 970,000 more from April 2027. Each event sends a wave of buyers looking for an answer at the same moment.

Geography changes the answer. In our country study, ChatGPT named both QuickBooks and Xero for small business accounting software in every country, but put QuickBooks first in every US and Canadian run and Xero first in every UK and Australian run. Across all 40 questions in that study, ChatGPT put the same brand first in all four countries for only 25.4% of questions. Location matters just as much for payroll software in AI answers, where tax rules differ by state and country.

How does an AI recommendation turn into subscription revenue?

Through a trial for owners, through the accountant for advised businesses, and increasingly inside the assistant itself.

The owner path. The owner asks, gets three or four names, opens one or two trials and subscribes to the product that imports their bank feed and invoices without friction. The value is the monthly fee multiplied by how long they stay. With Xero’s monthly churn of 1.14%, we infer that a typical new customer stays for years, so one recommendation can carry several years of revenue, plus payroll, payments and add-ons sold later.

The accountant path. The accountant asks an assistant about a niche need, such as construction job costing or multi-currency, compares options and then standardizes clients on one platform. One firm’s decision can move dozens of client subscriptions. Accountants in Capterra’s 2026 buying survey (opens in a new tab), based on 139 buyers in the accounting profession, named product identification as a challenge 33% of the time, so help in finding the right product has real value to them.

The in-assistant path. When a product works inside ChatGPT, discovery and use can happen in the same conversation. Intuit said its apps in ChatGPT would help it reach new audiences beyond its approximately 100 million customers (opens in a new tab), on a platform with 700 million-plus weekly users. How many paying QuickBooks customers this produces has not been published.

Why does an assistant put QuickBooks, Xero or a challenger first?

Platforms document how they search, not how they choose; studies point to geography, consistent facts and independent coverage.

Documented by the platforms. Before answering, AI Overviews and AI Mode may use what Google calls (opens in a new tab) a “query fan-out” technique, issuing several related searches across subtopics. A single question about the best software for a landlord can therefore pull in pages about tax rules, pricing and reviews at the same time. Google also says there are no extra requirements for appearing in these features beyond normal search eligibility.

Observed in studies. Our country study shows the user’s location changes which accounting brand comes first. Our four-assistant study found B2B software had the highest agreement between ChatGPT, Gemini, Perplexity and Claude of eight industries, with an overlap score of 0.543 on a 0-to-1 scale. We infer that once a category’s leaders are fixed in answers, challengers face a crowded shortlist.

Our inference about trust factors specific to accounting. A reasonable expectation is that assistants lean on the signals accountants themselves trust: listings in tax authority software directories, such as HMRC’s list of compatible products; partner and certification programs; integration directories; reviews from accountants and bookkeepers; and plain statements of which countries, tax rules and business sizes a product supports. No platform has confirmed that any of these accounting-specific signals affects which product it names.

What does a books platform lose when assistants leave it off the list?

A customer who signs up elsewhere is usually gone for years, because changing books is painful.

The economics above make the cost clear: a subscription that lasts years, sold to a business that rarely switches without a trigger. When the triggers come, such as a discontinued desktop product or a new tax rule, buyers decide quickly. If the assistant’s shortlist leaves you out at that moment, you miss the switching window, not just one sale.

Buyers also struggle to find the right fit without help. In Capterra’s survey of accounting-profession buyers, 44% ended up choosing software that disappointed them, and around a third (36%) of purchases were followed by finding a better match later. We infer that a product that answers fit questions clearly has a chance to be the better match before the purchase, not after it.

Errors cost money too. In our pricing study, 61.9% of the plan prices four assistants gave for 45 software products were fully faithful to the official pricing page; 7.6% differed, usually because an older figure was still published somewhere. For a category that competes on monthly price, an outdated plan price in an AI answer can lose the comparison.

How does GEO work for accounting software?

Generative engine optimization (GEO) gives assistants accurate, checkable facts about your plans, markets and integrations. No accounting vendor can be promised a recommendation.

For an accounting software company it usually means:

  1. One clear story everywhere. State the business sizes, trades, countries, tax rules and integrations you support in the same words on your site, app marketplaces, review profiles and partner directories.
  2. Country pages that stand on their own. Since answers change by country, publish separate, current pages for each market’s compliance needs, such as Making Tax Digital in the UK or sales tax in the US.
  3. Advisor-facing proof. Accountants and bookkeepers write reviews, answer forum questions and publish comparisons. Their independent coverage is the third-party evidence assistants can cite.
  4. Migration and comparison content. Publish fair guides for buyers leaving desktop software or outgrowing a starter tool, including where your product is not the right fit.
  5. One current pricing page. Retire old plan pages and figures so assistants find one price per plan. When an assistant still quotes a retired plan, fixing wrong brand information in AI answers shows how to find the page it came from.
  6. Measurement by market. Track a fixed set of owner and accountant questions in each country you sell in, across ChatGPT, Gemini, Perplexity, Copilot and Google, and compare it with trial signups. Expect answers to vary run to run; see why AI answers about your brand change.

What don’t we know yet about AI answers and accounting software sales?

How many books subscriptions begin with an AI answer; no published study has counted them.

  • The owner surveys are small or come from companies with a stake in AI, and the accountant data comes from Intuit, the market leader.
  • No accounting software vendor has published AI referral or trial data, so we cannot quote conversion rates for this category.
  • Our country finding comes from one day of five runs per country on ChatGPT and Gemini; answers may differ on other days or assistants.
  • Whether being named by an AI assistant matters more than an accountant’s recommendation is unknown. Most likely they work together, but that is our inference.
  • AI visits often leave no clear trace in analytics; see why analytics miss AI visibility.

How can an accounting software company see whether AI answers win it subscribers and accountant partners?

Check, market by market, what the main assistants say about you for your best customers’ questions.

Run the fit, switching, compliance and price questions your owners and accountants actually ask, note who is named first and whether your plans and prices are right, then compare the gaps with trial and partner signup data. For an outside reading of those answers, weighted toward subscriptions and accountant adoption, ask us for an accounting software visibility review. The generative engine optimization service page describes how we turn that review into country-by-country fixes for plan facts, comparison pages and accountant-facing coverage.

Frequently asked questions

Does ChatGPT recommend QuickBooks or Xero?

Both, and the order depends on where the user is. In our country study, ChatGPT named both everywhere but led with QuickBooks in the US and Canada and with Xero in the UK and Australia. That was one study day, so treat it as a snapshot.

Do accountants still influence which accounting software small businesses buy?

Yes. Intuit said more than 80% of its mid-market QuickBooks Online customers work with external firms. Accountants also use AI more than their clients, so they may meet AI answers about your product before the owner does.

Can a smaller accounting software company get named against QuickBooks and Xero?

It can for specific needs, such as a trade, a country or an integration, more easily than for “best accounting software” in general. Our article on how small brands get recommended by AI summarizes the research.

Are AI assistants accurate about accounting software prices?

Often, but not always. In our test of 45 software products, 61.9% of quoted plan prices were fully faithful to the vendor’s page, so buyers should confirm on the pricing page and vendors should keep only one current price per plan online.
