Across six buyer questions about professional services automation software, three products tied for first: BigTime, ConnectWise PSA and Scoro were each named in 4 of the 6 answers that ChatGPT and Gemini produced. We ran the measurement on 2026-08-06, one live web search per question, and recorded every product named and every source domain cited. No single product was named in all six answers.
The names at the top
Below the leaders, three products landed in exactly half the answers: Autotask, Kantata and Projectworks were each named in 3 of the 6. After that the field splinters. Six products (Accelo, Certinia Professional Services Cloud, Rocketlane, Ruddr, SuperOps and Wrike) were named in 2 of the 6 answers, and six more were named in only 1. Eighteen distinct product labels surfaced across just six questions, which tells you neither assistant has a settled default for this category.
The shortlist changed with every question
This is the part worth reading twice. The shortlist was not one list, it was six different lists, and the wording of the question decided who appeared.
The bare query, "best professional services automation software," returned 8 names, and it was the only question that surfaced Productive, which was named in 1 of the 6 answers and nowhere else.
"Best free professional services automation software" returned a different set of 5: Kantata, Scoro, Accelo, BigTime and Projectworks. Three of those, Kantata, BigTime and Projectworks, never appeared in the plain "best" answer, so switching one word swapped in three names the generic question missed.
"Most affordable professional services automation software" tied for the longest list at 8 names, and it was the only question to surface Teamwork and the short label "Certinia," each named in 1 of the 6 answers. Ruddr, named in 2 of 6 overall, appeared here and in the small-teams question but never in the plain "best" answer.
"Best professional services automation software for small teams" gave the shortest answer of all, just 4 names: BigTime, ConnectWise PSA, Ruddr and SuperOps. SuperOps, named in 2 of 6 overall, only ever appeared in this question and in "what should I use."
"What professional services automation software should I use" acted like a catch-all and surfaced the most one-off names: of its 6 products, three (Assembly, Rev.io PSA and the short label "ConnectWise") appeared in that answer and in no other.
Six labels in total were each named in exactly one of the six answers, and each was locked to a single phrasing: Productive in "best," Assembly, Rev.io PSA and "ConnectWise" in "what should I use," and Teamwork and "Certinia" in "most affordable." If you tracked only the generic "best" query, you would never see five of them. The phrasing, not the product, decides who shows up.
Where the answers came from
Two domains fed every answer: gartner.com and reddit.com were each cited in all 6 of the 6 answers. A Reddit thread carried the same weight as Gartner here, which is the pattern we see over and over: community discussion is a primary source for these assistants, not a footnote. Quora added to that, cited in 2 of the 6.
The next tier mixed a directory, a roundup and a vendor blog: g2.com, assembly.com and thedigitalprojectmanager.com were each cited in 5 of the 6 answers. G2 was the only mainstream review directory to appear at all. Capterra did not show up in a single answer, and the one other directory-style source, softwarereviews.com, appeared in just 1 of the 6.
Here is the insight that matters if you sell in this category: several products were named partly because their own website was one of the sources. scoro.com was cited in 3 of the 6 answers and Scoro finished top-three at 4 of 6. bigtime.net was cited in 2 of the 6 and BigTime also finished top-three at 4 of 6. ruddr.com and superops.com were each cited in 3 of the 6 and fed the answers that named Ruddr and SuperOps at 2 of 6 each. Owning a page the assistant treats as a source is doing real work here.
There is a warning in the same data. assembly.com was one of the most-cited sources at 5 of 6, yet the product Assembly was named in only 1 of the 6 answers. Their content is feeding the assistants other vendors' shortlists more than its own product, which is the clearest sign that being cited and being named are two separate wins.
What this means if you sell PSA software
None of this ran on market share. Neither assistant weighed revenue or install base, it read a handful of pages and named whatever those pages named. The lever is the source list. To get named in this category you have to be present, by name, in these exact places: the Reddit and Quora threads buyers read (cited in 6 and 2 of the 6 answers), the roundup at thedigitalprojectmanager.com (5 of 6), the G2 listing (5 of 6), and, as Scoro and BigTime show, your own comparison and category pages, cited 3 and 2 times.
The test is narrow and you can run it by hand: take the exact question a buyer would type, open the pages the assistant cites for it, and check whether your product is named on them. In this data, being missing from the "what should I use" sources cost three separate mentions, because that one phrasing surfaced Assembly, Rev.io PSA and ConnectWise and nothing carried over from the generic query.
The full list, counted
Below is every product named in at least two of the six answers, plus the two brands the assistants wrote under two different labels. We kept ConnectWise PSA (4 of 6) and ConnectWise (1 of 6) as separate rows, and Certinia Professional Services Cloud (2 of 6) and Certinia (1 of 6) as separate rows, because that is how the answers read. We did not merge them into a bigger number the data does not show.
| Product | Named in | Share |
|---|---|---|
| BigTime | 4 of 6 | 67% |
| ConnectWise PSA | 4 of 6 | 67% |
| Scoro | 4 of 6 | 67% |
| Autotask | 3 of 6 | 50% |
| Kantata | 3 of 6 | 50% |
| Projectworks | 3 of 6 | 50% |
| Accelo | 2 of 6 | 33% |
| Certinia Professional Services Cloud | 2 of 6 | 33% |
| Rocketlane | 2 of 6 | 33% |
| Ruddr | 2 of 6 | 33% |
| SuperOps | 2 of 6 | 33% |
| Wrike | 2 of 6 | 33% |
| ConnectWise | 1 of 6 | 17% |
| Certinia | 1 of 6 | 17% |
Four more products were each named once and only in a single question: Assembly, Productive, Rev.io PSA and Teamwork.
Why Glotier is absent, and why that matters
One honest note to close. Glotier does not sell professional services automation software, so we are correctly absent from all six of these answers, and we would be surprised to see ourselves in them. We build the measurement itself: what we just did to this category is exactly what we run for a customer's own category, on their real buyer questions. The check is free, it takes about a minute, and there is no account to create.
