Fourteen AI models were asked for ERP system six ways each, on behalf of a small, a mid-market and an enterprise B2B company: 252 answers, in which a judge labeled 58 products. Seven of them carry at least 10 labels and a first choice, and are ranked. This guide walks the top seven in the order the mid-market standing puts them, with what the models said for and against each, in their words. Oracle NetSuite leads at 41% of first choices, a clear leader.

## Questions the record answers

**Which ERP system do AI models name first most often?** Oracle NetSuite, in 41% of first choices for a mid-market B2B company in the November 2026 Edition, from 62 labels. The index calls that a clear leader.

**Does the answer change with the size of the company?** Small business: Odoo at 31%. Mid-market: Oracle NetSuite at 41%. Enterprise: SAP S/4HANA at 48%. 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; scale-constrained Oracle NetSuite. The table above has the counts.

**How stable is one answer?** The repeat measurement is published with the next edition.

**Where do the answers come from?** Fourteen of the fourteen models return sources. Their 69 answers here cite 684 pages; the sites cited most are erpresearch.com, capterra.com, netsuite.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.
