Accounting software: what twelve AI models recommend, and why, September 2026
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.

How a product gets on this list
The judge reads every answer
A product is on the record because a model named it in an answer and the judge labeled the naming: first choice, alternative, mention, caution or warning, each with the sentence it came from. 56 products were named for accounting software this edition.
10 labels and a first choice
A product is ranked once it carries 10 labels in a segment and at least one first choice there. Below that it is named but not ranked, and it says so on its page. The vendor table that folds spellings into products is versioned; this page was scored under vv2026-09.2.
6 points
The same categories are asked again with nothing changed to measure how much an answer moves on its own. A change in share smaller than the floor is not reported as a change. The repeat, model by model.
