- Size
- Seven bands. Your worker count and your revenue are banded separately, and you sit in whichever gives the smaller of the two — B Lab’s own rule, and the one most often got wrong.
- Sector
- Five sectors, split by operational footprint: agriculture, manufacturing, wholesale and retail, and services with either a minor or a significant footprint.
- Phase
- Year 0 to certify, Year 3 and Year 5 to recertify. Phases are cumulative, so an organisation at Year 5 still owes everything from Year 0.
- Risk flags
- Some sub-requirements are triggered by risk rather than size — a high-risk sector, or operating in a high-risk geography. Those come from B Lab’s risk-profiling step.
