How guidance is evaluated
Methodology
Guidance is written to explain the tool and common invoice concepts while marking the boundary between general information and decisions that require a contract, jurisdiction-specific source, or adviser.
Product facts first
Claims about storage, calculations, output, network behavior, and supported fields should match the tested release. A future feature is not described as available until its implementation and evidence exist.
Source and scope review
Legal, tax, privacy, accessibility, and platform statements require an appropriate source and a review date. General examples avoid claiming that one rule or tax percentage applies everywhere.
Future recommendations
If recommendations are introduced later, evaluation will consider relevance, documented features, costs, privacy behavior, and source quality. Compensation cannot silently determine ordering or erase a nearby disclosure.
