Store Upgrades Guide

Store upgrades define your income ceiling in My Squishy Box Store. Every coin spent on expansion, shelves, or staff should return measurable customer throughput or per-sale revenue increases. This overview ranks upgrade categories by return on investment across game phases.

Upgrade Categories

Shelf upgrades increase capacity per rack and reduce restock frequency. Staff upgrades automate restocking and checkout. Floor expansion adds new rack slots. Decorations improve aesthetics but minimal early ROI.

Deep dives: shelf upgrades and staff upgrades.

Phase-Based Priority List

Early: shelf capacity, then box quality. Mid: staff hires, then expansion. Late: premium decoration and max expansion for Collection Book display space.

Use the profit calculator before any purchase above 1,000 Cash.
