In AI search for accounting firms in Singapore, one firm leads on both Google and AI. Across 20 buyer questions, Sleek has the highest composite score, 60.7 out of 100, and the most citations, and it is first in Google’s organic results for “accounting services singapore”. Accounting is one of two industries in this study where that happens. Below the top, the lists part ways, and the company registry, ACRA, has more listed citations across the four scored engines than any firm: 37, summed across host variants, against Sleek’s 23.

Three findings
Google’s first result is also AI’s highest scorer
Sleek is the first result for “accounting services singapore”. It also has the highest composite score (60.7) and the most raw citations, 23 across the four scored engines, including 10 on Perplexity and 10 on Google AI Overviews. Its lead over the next firm is 9 citations.
Two of AI’s top three are missing from Google’s first page
Excellence Singapore (46.4) and VIVOS (39.3) are second and third on the AI score. Neither appears in Google’s organic results for either head term. VIVOS is one of only 3 of 20 firms cited on all four scored engines. Google’s second result, BoardRoom, shares =4 in AI with two other firms on 32.1.
Six firms from Google’s first page go uncited
6 of 20 firms have no citations on any scored engine, and every one of them came into the panel through Google’s first page. Tan Chan ranks fourth for “accounting services singapore” and has no citations on the four scored engines. AI Overviews on Google keyword searches, a separate panel we report but do not score, cite it 8 times.
Who AI cites instead
Here, AI mostly cites firms. Across the 15 most-cited domains on each scored engine (267 citations), business websites take 160 (60%), government sources 59 (22%) and aggregators 13 (5%). That business share includes firms outside our 20. Three stand out:
- ACRA, the company registry, is ChatGPT’s single most-cited source (15 citations), second on Perplexity (11) and in the top 15 on all four scored engines. Many questions in the panel are about incorporation and company secretaries.
- Statrys, a Hong Kong-headquartered business-account provider with Singapore incorporation pages, is Perplexity’s single most-cited domain (12). It is also in the top 15 on ChatGPT (7), Gemini (4, level with Excellence Singapore at the top) and Copilot (5, level with ACRA). We left it out of the 20 because it is not a Singapore accounting or corporate secretarial firm.
- The Big Four each appear in ChatGPT’s top 15 (3 citations each). Three questions ask about the Big Four or the top accounting firm, and the Big Four are excluded from the ranking.
The B2B matching service FYAdvisers (7 on ChatGPT) is the most-cited aggregator.
Google vs AI in accounting
Google organic position 1
AI rank: 1
Highest AI score: 60.7 / 100
Google term: accounting services singapore. AI ranks apply only within this panel; tied scores share their rank.
View data: Google vs AI in accounting
| ”accounting services singapore”, Google top 3 | AI top 3, by composite score | |
|---|---|---|
| 1 | Sleek | Sleek |
| 2 | BoardRoom | Excellence Singapore |
| 3 | Xero (adviser directory) | VIVOS |
Only Sleek is in both top threes. Google’s third result is the accounting software Xero’s adviser directory, not a firm.
Technical readiness
Of the 20 firms:
- Fewer than 3 put a barrier in front of AI crawlers.
- 13 publish an llms.txt file.
- 20 have structured data (JSON-LD) on the homepage.
- 16 mark themselves up as a local business.
No firm’s robots.txt bars an AI crawler from its homepage. These limited homepage checks cannot explain why a particular firm was or was not cited.
The accounting and corporate secretarial playbook
Each move below is a test to run and track, not a result this study measured.
→ Explain the registry process in your own words. Most of the 20 questions are about incorporation, corporate secretaries or bookkeeping, and ACRA’s pages are cited on all four scored engines. A clear guide on your own site that stays consistent with ACRA’s current requirements and links to them is worth testing.
→ Set out what each service covers. Nine of the 20 questions ask what something costs, from a corporate secretary to bookkeeping, an audit or incorporation. A page describing what each service includes and how it is priced is a reasonable test. Keep it to service descriptions, not tax or financial advice.
→ Track each engine separately from page one. Every uncited firm in this panel ranks on Google’s first page, so a ranking report will not show the gap. The engines also differ: on Perplexity, the panel firms cited most are Sleek (10 citations), BoardRoom (6) and Osome (5), while Gemini spreads its citations, with no panel firm above 4.
How this was measured
We took every accounting, bookkeeping, audit, tax, incorporation and corporate secretarial question with a Singapore or buying modifier in Ahrefs Brand Radar’s Singapore database, 20 in all, and counted the citations to each firm’s website in the 80 stored answers from ChatGPT, Gemini, Perplexity and Google AI Overviews (AI Mode and Copilot recorded, not scored). The Big Four were excluded from the ranking. Measured, not modelled, in November 2026. This chapter reports citations only and is not financial advice. Full method: How we measured this.
