Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 146 of the 155 answers that named ADP TotalSource and are not a share of its labels.
587 of the 587 domain citations in answers naming ADP TotalSource came from somebody else's page.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.
An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

What ADP TotalSource's own pages state, read October 5, 2026: adp.com/logins/adp-totalsource.aspx, adp.com/resources/demos/totalsource-demo.aspx, adp.com/what-we-offer/products/totalsource-peo.aspx, adp.com/contact-us/customer-service/erc-support-for-adp-totalsource-clients.aspx, jobs.adp.com/en/jobs/279686/adp-totalsource-peo-cpa-channel-sales. A claimed page can correct any of them.
Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when ADP TotalSource's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as ADP TotalSource, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
A new claim receives the current edition's vendor brief for ADP TotalSource by email, built from the raw record of the edition. It shows:
ADP TotalSource is among the products AI models recommend first in PEO providers this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
Badges read on light and dark pages. Alt text carries the claim, the category, the edition and the index, so it stays a citation where the image does not load.
