CosPos 同人展 POS 銷存系統

CosPos is a mobile POS system designed specifically for anime conventions, markets, and pop-up stalls.

No more laptops or paper notebooks—just your phone for checkout, inventory management, and reconciliation.

■ Built for Stall Owners
At conventions and markets, internet connections are often slow and unstable, and long queues form as soon as crowds arrive.

CosPos is designed to address these real-world scenarios: large, user-friendly buttons, checkout completion in three seconds, and the ability to continue selling offline.

• Automatically calculates change upon entering the actual amount received.

【Offline Checkout Support】
