Movement

This is the first edition on this tier, so no move can be computed for BILL yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated BILL across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“BILL is widely adopted by nearly half a million businesses, with users citing improved visibility, faster reconciliation, and reduced manual work” Claude Haiku 4.5 · Business bill pay · paraphrase prompt · first choice

“For most mid-market B2B companies, BILL is the top choice due to its scalability, broad payment options, and strong AP automation features.” Mistral Small · Business bill pay · direct prompt · first choice

“BILL AP/AR and AvidXchange are the top recommendations due to their strong user ratings, scalability, and comprehensive feature sets.” Mistral Small · Accounts payable automat · paraphrase prompt · first choice

“BILL is the heavyweight market leader... It offers the most robust internal controls, audit trails, and customizable approval workflows.” Gemini 3.5 Flash · Business bill pay · comparative prompt · first choice

And against it

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.

“BBB rating 1.09/5 (108+ reviews), 188 complaints in 3 years. Common issues: payment delays/holds, poor customer support, unauthorized charges” Grok 4.1 Fast · Business bill pay · negative prompt · hard negative

“Users frequently report sync issues between the platform and their primary accounting software... defeats the purpose of automation.” Qwen 3.7 Flash · Accounts receivable auto · negative prompt · hard negative

“Verdict: Avoid if you have complex approval workflows, rely on tight cash flow, or have a low tolerance for support friction.” DeepSeek V4 Flash · Accounts payable automat · negative prompt · hard negative

“Platforms to Approach with High Caution or Avoid ... Bill.com: ... the unexpected holding of funds or delays in payouts” Qwen 3.7 Flash · B2B payment acceptance · negative prompt · hard negative

What carried it into the answer

The sites and pages cited by the answers that named BILL. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 544 of the 650 answers that named BILL and are not a share of its labels.

Claim this page

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 BILL'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 BILL, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at bill.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
