Head to head

Thomson Reuters ONESOURCE Tax Provision vs Bloomberg Tax Provision Thomson Reuters ONESOURCE Tax Provision vs Longview Tax Thomson Reuters ONESOURCE Tax Provision vs Avalara

Head-to-head pages are published for mid-market buyers, so these open on mid-market figures, not enterprise.

All ten head-to-head pages: the top five products, each against each

Thomson Reuters ONESOURCE Tax Provision vs Vertex Bloomberg Tax Provision vs Longview Tax Bloomberg Tax Provision vs Avalara Bloomberg Tax Provision vs Vertex Longview Tax vs Avalara Longview Tax vs Vertex Avalara vs Vertex

One product takes 64% of first choices here, so the chart would put eight markers in one corner and one at the far edge. The two measurements it plots are columns in the standing above: share, and the negative label rate. Zero products carry a negative rate above 25% in this category.

What they warned about

Four of twelve models held their first choice under the paraphrase. GPT-5.4 mini, Gemini 3.5 Flash, Perplexity Sonar, Mistral Small, Llama 4 Maverick, Kimi K2, GLM 4.7 FlashX and MiniMax M2.5 changed. A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.

“Pricing is often opaque or quote-based, and it lacks the per-user flexibility of Tagetik for very large, distributed teams.” GLM 4.7 FlashX, budget prompt

What they cite

Twelve of the twelve models returned a source list in this edition: four return the pages they cited and eight the search results they consulted.

Sites the answers cite

68 of 72 answers in this category came back with a source list, from 12 of 12 models: citations where the model returns them, or the search results it consulted. 1094 links across 213 sites, every framing counted. Ranked by the number of answers carrying the site or page.

Search against answers

Each company's standing in the answers beside its site's footprint in Google search, one row a site: the products the models named on it with their shares, and the share they add up to; monthly searches on Google, and DataForSEO's estimate of AI search demand (modeled from search signals, directional, not a count of queries to any assistant), for the most-searched of the company's and its products' names (the name is in each row's hover text); estimated monthly organic visits to the site; and its best position in Google's top ten for “best corporate tax provision software”, “corporate tax provision software”, “tax provision tools”. US estimates from DataForSEO and Google's Ads Transparency Center. A small company's site, or a mid-sized company's site for its flagship, is marked company; a product on a large parent's site (Google, Microsoft) has no site figures. A column with no figures for this category is left out, and an empty cell means none were seen, not none exist. Two measurements side by side: neither is read as the cause of the other.

How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
