Not every document needs the same depth of expert review. Ask these in order, stop at the first yes, and the budget follows the risk.
FDA, EU MDR and NMPA submissions · IFUs and labels · contracts · patents · financial disclosures · safety instructions
Brand campaigns · publishing · film and short drama · games · product launch content
Product and technical documentation · specifications · support content · marketing collateral
Internal reference · research · knowledge bases · high-volume e-commerce listings
Rule of thumb: if a regulator, court or auditor may read it, choose L3 — whatever the word count.
