## Questions the record answers

**Which ERP system do AI models name first most often?** Oracle NetSuite, in 39% of first choices for a mid-market B2B company in the October 2026 Edition, from 55 labels. The standing is contested: the models did not settle on one product.

**Does the answer change with the size of the company?** Small business: Odoo at 39%. Mid-market: Oracle NetSuite at 39%. Enterprise: SAP S/4HANA at 52%. Each standing is computed within its segment and never pooled.

**Which framing changes the answer?** The direct, paraphrase, budget and scale framings count toward share. The product named first differs by framing: direct Oracle NetSuite; paraphrase Oracle NetSuite; comparative SAP S/4HANA; budget-constrained Odoo. The table above has the counts.

**How stable is one answer?** Asked again with nothing changed, the models moved their own first choice 67% of the time across the repeat sample; Across the categories asked twice, a leader's share moved 3 points at the median and the index calls a change only above 10 points.

**Where do the answers come from?** Fourteen of the fourteen models return sources. Their 77 answers here cite 974 pages; the sites cited most are erpresearch.com, randgroup.com, erp-pilot.com. The category page lists them all.

**Can a vendor pay to be on this list?** No. A product is on the record because a model named it. A vendor can claim its page, propose corrections to the vendor table and be told when its standing moves; it cannot change a label, a share or a rank, and the publisher's conflicts are disclosed on the method page.
