Sourcing, indexes, corrections and disclosure.
Prices and figures are taken from public price lists, official documentation, filings or named datasets, and are linked at the bottom of each article with the date we checked them. We do not print numbers we cannot source.
Recurring indexes state their composition, collection method and recalculation schedule. Historical values are never edited retroactively; corrections are appended.
Where a real range exists (for example, app stacks that vary by store), we publish the range and the assumptions, not a single invented number.
Errors are corrected in the article with a dated note. Request a correction at desk@commercequarterly.com.
Articles on this site are drafted with AI language models, working only from the sources, indexes and data described above. Every article carries a short "AI-drafted from sourced data" note next to its byline for exactly this reason.
Some of our coverage links to UTD's own Shopify themes, alongside independent products and services we cover the same way. Some links may earn the publication a commission. Neither UTD's ownership of this site nor any commission ever decides what we cover or how products rank; rankings follow the published numbers.
