Shixian

What it is

Shixian is a full-stack restaurant management SaaS for small-to-mid restaurants. From kitchen recipes to customer table-QR ordering to end-of-day reconciliation — one system, four ends, fully unified:

End	For whom	What
Admin Dashboard	Owner / Manager	Menu / Inventory / Recipes / Reports / Settings
POS	Wait Staff / Cashier	Tables / Orders / Add Items / Checkout / Print
Customer H5	Diners	Scan-table-QR ordering / Self-checkout
Delivery Receiver	Owner	Meituan / Eleme orders + kitchen sync

What’s working

• Full menu / inventory / recipe pipeline: serving a dish auto-deducts inventory by recipe
• Multi-end order state machines: dine-in & delivery each with full lifecycle (cancellations, post-paid additions, refunds with rollback)
• Printer management: kitchen / cashier / label printers grouped and routed
• Payment aggregator stub: WeChat / Alipay interfaces ready (awaiting merchant credentials)
• Excel bulk import/export: inventory, orders, recipes
• Stocktake / waste / unit conversion: full restaurant accounting compliance
• Dual-company split-billing: a single restaurant can run two legal entities side-by-side (mixed dining + canteen scenarios)

Status

Deployed to a real restaurant in production (36 DB migrations, 4 apps, 20+ modules). Not a demo — people use this every day to run their business.

Shixian does not

• “AI menu recommendation” / “smart pricing” predictions — the owner decides
• Upload or share restaurant business data
• Force a subscription — buy-once available
