## What is Sokubai?

Sokubai is a booth POS, cashier, and inventory app for doujin events, comic markets, artist alley, conventions, and craft fairs.

Tap a product card to add it to the cart, calculate change instantly, and keep your inventory in sync — everything works offline so it stays reliable even on crowded venue Wi-Fi.

■ Key Features

【Tap-to-Sell】
- Pre-register products with name, price, and image
- Tap a product card to add it to the running total
- See cart line items at a glance

【Instant Change Calculation】
- Quick cash-received presets (exact / next $5 / next $10 / next bill) — no payment processing, just fast cash-tendered input
- Large change display so any volunteer cashier can handle the line

【Inventory Tracking】
- Set the number you brought; remaining stock auto-decrements
- Sold-out items are automatically grayed out

【Sales History & CSV Export】
- Per-transaction history with timestamps
- Export as CSV for accounting or post-event analysis

【18+ Age Verification (Optional)】
- Adult-content products show a seller-side confirmation checkbox

【Fully Offline】
- All features work without an internet connection
- Local data persistence keeps your event safe even if Wi-Fi drops

【Multi-Day Event Support】
- Presets for "Today only / Sat-Sun / 3-day" events

■ Built For

- Comic Market (Comiket), COMITIA, Game Market, and other doujin events
- Artist Alley sellers at conventions
- Flea markets, craft fairs, school festivals, hand-made events
- Food trucks and small pop-up stands

■ Designed Around Real Pain Points

Sokubai is built to address common complaints with existing register apps: hidden running totals, slow bill-combination entry, and the lack of direct amount input.

Available on iPhone and iPad. Item data sharing between devices (cashier + helper) is planned for a future update.

We welcome feedback through App Store reviews or support email.
