Rankings are measured from sampled AI answers — never editorial, never paid. Orbator builds AI-visibility tooling; when Orbator itself appears in any category, it is measured by the same rules as everyone else.

Across 28 sampled AI answers from 4 engines, QuickBooks is recommended most often — appearing in 75% of recommendations, followed by Zoho (67.9%) and FreshBooks (67.9%).
This is a measurement of share of voice across 4 AI engines — not an editorial pick. See the full ranking below.
Orbator asked Gemini, ChatGPT, Claude and Perplexity buyer questions about invoicing software and sampled 28 answers between Aug 21, 2026 and Sep 18, 2026. Recommendation share counts the answers that recommended or listed a product, so a passing mention or a warning adds nothing to it. A category publishes once it holds at least 20 independently sampled answers in the window. Read the full methodology or download this ranking as CSV.
Buyer prompts in this window split across five intents, and the leaders differ by intent. QuickBooks led the problem_solving prompts about sending professional invoices and chasing late payers, recommended in 87.5% of 8 runs. FreshBooks and QuickBooks tied on the best_in_category prompts at 87.5% of 8 runs each. Zoho led the alternatives prompts at 100% of 4 runs, alongside Wave at 100%, and led the multi-currency recommendation prompt at 100% of 4 runs. The comparison prompt on standalone invoicing versus full accounting had no single leader, with QuickBooks, Wave and Zoho each at 50% of 4 runs.
Published prices sit close together. QuickBooks lists Simple Start at $19 a month, FreshBooks lists Premium at $7 a month, $70 a year, and Xero lists Established at $9 a month, all last verified 2026-09-05.

Reading the numbers: Share is a point estimate on 28 sampled answers, so each row also shows its 95% CI — the Wilson score interval around that share. When two products' intervals overlap, the gap between them isn't statistically meaningful at this sample size. First pick is the share of a product's recommending answers where it was named first, which separates “always mentioned” from “usually the top recommendation”. Full methodology.

QuickBooks ranks first, recommended in 75% of the 28 sampled answers in the 4-week window to 2026-09-05. Its mention breakdown splits 10 recommended against 11 listed, with 2 context mentions and 1 warned against. Engine spread runs from 100% of Claude's 7 answers down to 42.9% of ChatGPT's 7 answers. Pricing lists Simple Start at $19 a month, last verified 2026-09-05.
Zoho ranks second at 67.9% of 28 sampled answers in the same window, with 13 recommended against 6 listed and 1 context mention. It was recommended in 85.7% of Claude's 7 answers and 57.1% of both Gemini's 7 and ChatGPT's 7.
FreshBooks ranks third, also at 67.9% of 28 sampled answers, split 8 recommended against 11 listed, with 2 context and 1 warned against. It reached 100% of Claude's 7 answers and 28.6% of ChatGPT's 7.
Wave ranks fourth at 57.1% of 28 sampled answers, split evenly at 8 recommended and 8 listed. Claude recommended it in 85.7% of 7 answers, Gemini and Perplexity in 42.9% of 7 each.
Xero ranks fifth at 53.6% of 28 sampled answers, with 7 recommended against 8 listed, 2 context and 1 warned against. Claude recommended it in 100% of 7 answers, ChatGPT in 0% of 7. Established lists at $9 a month, last verified 2026-09-05.
Three of the four engines shared a leader among the top five. Claude, across 7 answers, recommended QuickBooks most. Gemini, across 7 answers, did the same. Perplexity, across 7 answers, also led with QuickBooks. ChatGPT, across 7 answers, led with Zoho instead.
The widest gap belongs to Xero. ChatGPT recommended it in 0% of its 7 answers. Claude recommended it in 100% of its 7 answers. That is a spread of 100 points between the two engines on a single product in the top five.
QuickBooks itself is not uniform either, ranging from 100% of Claude's 7 answers to 42.9% of ChatGPT's 7. A shortlist built from one engine will look different from a shortlist built from another.
This is the first measured window on record for invoicing software. It covers 2026-08-08 to 2026-09-05, 28 days, with 28 sampled answers across Claude, Gemini, ChatGPT and Perplexity at 7 runs each. There is no prior window to compare against, so no product entered or left the top ten, and no share change can be reported yet.
The current standings: QuickBooks leads at 75% of 28 sampled answers, followed by Zoho and FreshBooks, both recommended in 67.9% of those 28. Wave sits at 57.1% and Xero at 53.6% of the same 28. Confidence intervals are wide at this sample size, with QuickBooks spanning 56.6 to 87.3 and Xero spanning 35.8 to 70.5. The next window will show whether that order holds.
