Finance AI Recommendation Index, September 2026 Edition. Page: https://finance-ai-index.com/accounting/accounting-software/guide/

Twelve AI models were asked for accounting software six ways each, on behalf of a small, a mid-market and an enterprise B2B company: 216 answers, in which a judge labeled 56 products. Five of them carry at least 10 labels and a first choice, and are ranked. This guide walks the top five in the order the mid-market standing puts them, with what the models said for and against each, in their words. Sage Intacct leads at 40% of first choices, and the standing is contested.

## Questions the record answers

**Which accounting software do AI models name first most often?** Sage Intacct, in 40% of first choices for a mid-market B2B company in the September 2026 Edition, from 36 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: QuickBooks Online at 51%. Mid-market: Sage Intacct at 40%. Enterprise: Oracle NetSuite at 35%. 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 Sage Intacct; paraphrase Sage Intacct; comparative QuickBooks Online; budget-constrained Wave; scale-constrained Oracle NetSuite; negative Xero. The table above has the counts.

**How stable is one answer?** Asked again with nothing changed, the models moved their own first choice 68% 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 6 points.

**Where do the answers come from?** Twelve of the twelve models return sources. Their 62 answers here cite 666 pages; the sites cited most are learn.g2.com, thecfoclub.com, ramp.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.
