Sources first
Legal and working-time statements link to official or primary sources. Industry figures appear only with their origin, time period, and a clear explanation of what they do and do not show.
Formulas stay visible
Every calculator exposes its inputs, calculation steps, rounding rule, and limits. Hidden assumptions and universal target percentages do not belong in the calculation.
Product claims are tested
We describe only product features and integrations that are available and verifiable. Square and SumUp are currently available; Lightspeed is not.
Corrections stay traceable
We check reported errors against the source or the product. Substantive changes receive a new review date and are recorded in the SEO intervention history.
