Small business storage
E-commerce sellers might need 35–50 sq ft for inventory; tradespeople storing tools and equipment might only need 10–25 sq ft.

Maximising your storage space
- Use uniform box sizes — they stack better and save space
- Disassemble furniture — beds and tables take up less room flat-packed
- Store vertically — stack boxes high, heavy items at the bottom
- Create aisles — leave pathways to access items easily
- Label everything — you'll thank yourself later
