Each tool is rated /10 across five criteria. The final rating is the weighted mean, with ROI and accuracy weighted higher for finance workflows. Scores are refreshed on every review cycle and are independent of any affiliate relationship.
Every tool is tested on a real book of business with live bank feeds, sample invoices, and a small vendor list. We reconcile a month of transactions end-to-end before scoring.
