How many achievements are there?
Official Confirmed: the current Steam listing shows 108 Steam achievements for Pizza House Simulator.
That is a large enough set that a complete checklist is useful, but this launch version deliberately does not invent hidden conditions from names or icons. Exact unlock requirements should only be added when they are visible in Steam, the game, official notes or reproducible full-release testing.
Practical achievement strategy
Play through progression systems rather than chasing unknown hidden goals immediately: complete quests, use co-op if an achievement clearly references multiplayer, expand staff/automation, and interact with economy systems as they unlock. Keep a separate save backup only through normal platform/game mechanisms; do not edit save data just to force achievements.

The current Steam listing shows 108 achievements.
Does this guide list every hidden requirement?
Not yet. Requirements are only added after they are verified; names and icons are not enough evidence to invent conditions.
