Start with bunker purchase from spots like chumash or route 68, then set staff to manufacturing. Supplies need regular attention through theft missions or direct purchase at 75k which converts to product while you do other things.

Basic process is simple, keep supplies stocked wait for manufacturing then sell when ready. Getting equipment and staff upgrades really makes a difference with production speed and value, pushing profits from 39k to 78k per hour. Full bunker sales hit around 700k to 1.1m depending on lobby bonus.

Maybe interesting: supplies last about 2.5 hours with upgrades so plan supply runs accordingly. Running other businesses while waiting maximizes time efficiency. Watch for raid triggers if product builds up too high, keeping security upgrade helps with that.

Good to know: selling in populated lobbies risks attacks but gives bonus cash. Solo public sessions trade safety for lower profits worth considering depending on your style.

Product manufacturing keeps going as long as youre online doing whatever else catches your interest, makes it perfect for combining with import export or nightclub stuff.
