About this app

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.

■ Main Functions

【Fast Checkout】
• Add items to cart instantly with a single click, supporting quantity adjustments and on-site price negotiation.
• Built-in discount rule engine: apply discounts for purchases over a certain amount and bundled offers with one click.
• Customize payment methods (cash/mobile payment/credit card), with individual fee settings.
• Automatically calculates change upon entering the actual amount received.

【Offline Checkout Support】
• Checkout continues even if the exhibition network is down; data is saved locally first.
• Automatically syncs back to the cloud after network recovery, ensuring no missed or duplicate orders.

【Real-time Inventory Tracking】
• Deducts inventory from each transaction instantly; automatic low inventory alerts.
• Separate management of warehouse and exhibition inventory; one-click stocking and allocation.
• Supports product image, batch import, and category management.

【Sales Data Analysis】
• Real-time revenue statistics for the day/exhibition sessions, automatically updated every 30 seconds.
• Total revenue, fees, and net income are clearly displayed.

• Bestselling product rankings – instantly know which items need restocking after closing time.

【Exhibition (Event) Management】
• Sales data is segmented by "exhibition," allowing for separate settlements across multiple events.
• Invite partners to join via sharing codes; members can jointly manage products and orders.
• Post-exhibition settlement reports calculate each member's revenue.

【Multi-language Interface】
• Traditional Chinese, Simplified Chinese, English, Japanese

■ Who is it suitable for?

• Anime/Doujinshi convention/doujinshi vendors
• Handmade markets, weekend markets, pop-up shops
• Small businesses needing a lightweight POS but not wanting to rent a cash register

■ About Accounts and Data

• Account registration is required; data is transmitted encrypted via HTTPS.

• Account deletion within the app is supported: https://cospos.111.net.tw/legal/account-deletion

• This app contains in-app ads (Google AdMob).
