CCTV for a 3-floor office: what you need and what it costs
For a 3-floor office, about 18 cameras usually cover entrances, corridors, cash or stock areas and the outside. 18 cameras at 4 MP, recording continuously for 30 days with H.265, need about 14.7 TB of storage (with 20% headroom), so an NVR with at least 32 channels.

Questions
Dome or bullet cameras?
Domes suit indoors and are harder to turn away. Bullets suit outdoors and long distances. Most sites use a mix.
How much does a 18-camera system cost?
It depends on resolution, brand, cabling distances and installation. Post your requirement and sellers will quote cameras, NVR, drives, cabling and installation together.
Do I need an internet connection?
Only to view cameras on your phone. Recording works without internet.
