A new initial visibility study by Taptwice Media, an AEO agency based in India, found substantial differences in how leading AI engines represent industrial quoting and configure-price-quote software vendors, with citation behavior varying dramatically even when given exactly the same questions. The study tested ChatGPT, Perplexity, Claude, Google Gemini and Bing Copilot using 20 non-branded questions about industrial quoting, AI-native quoting software, configure-price-quote platforms and engineer-to-order workflows. Across 100 total AI-generated answers, Tacton, Salesforce CPQ/Revenue Cloud and Oracle CPQ appeared among the most frequently named companies across all five engines, while Epicor CPQ, SAP CPQ and DealHub appeared among the leading names in four of the five. Citation volume differed sharply: ChatGPT produced 791 citation occurrences spanning 322 unique domains, Perplexity generated 598 citation occurrences across 251 domains, Bing Copilot produced 97 citation occurrences from 56 domains, Google Gemini produced 56 citations from 48 domains, and Claude produced no source citations across any of the 20 tested answers. Claude also declined to name vendors in four questions, while the other four systems named at least one company in nearly every tested query. Tacton was named in 10 of ChatGPT's 20 answers, nine Perplexity answers, eight Gemini answers and six answers each from Claude and Bing Copilot.
