Cm3 & Avetta vs EHS Atlas — What Is the Difference?

Cm3 and Avetta are prequalification platforms — they are where the principal contractor checks your status. EHS Atlas is your management system — it is where you keep your documents current, generate your SWMS, track your training, and export your evidence pack for any prequalification platform. They serve different purposes. Use both.
