Is your revenue being shaved off by other companies’ “referral fees”?

💸

Paying referral fees
to listing sites, forever

→ Bring in new guests via your own Google, LINE and QR. Zero referral fees.

🔁

Guests come once
and never return

→ Prepaid passes, e-gift cards and win-back systematize repeat visits.

📊

No idea which dishes
actually make money

→ The AI menu advisor auto-classifies “star / cut” by cost × sales.

😩

Short-staffed,
the floor can’t keep up

→ Guest self-ordering + online reservations + waitlist run with fewer hands.

Not a pile of features.
They connect — and grow sales on their own.

Rivals are “order-only” or “reservation-only” dots. This OS runs on one shared dataset, so the features link up automatically and lift check size and table turnover together — a multiplier you can’t get by stitching separate apps.

📅→🧑‍🍳
Reservations → Shift planning

A 40-person party booking automatically raises the required headcount for that day and, matched with staff availability, drafts the shift

No more “fully booked but short-staffed”

⏱️→🍺
All-you-can-eat timer → Add-on orders

The order screen knows the elapsed course time: “one more?” before last order, “ready for a finisher?” near the end — auto-prompted (great for yakiniku)

Catch the moment guests order most — check size ↑

🧾→📊
Order history → Cost & profit

What sells flows straight into purchasing, food-cost %, and the profit dashboard; the AI advisor even flags “hero vs. drop”

See what actually makes money — with zero manual work

🛒→🔁
Order history → Cross-sell & return

Auto-suggests “ordered together” items — a drinks-only cart gets a snack; lapsed guests get win-back outreach

Grow this visit and the next

The full “grow-your-sales” loop, in one system.

Not just a system that takes orders. From acquisition to repeat visits to profit analysis — it brings the whole flow of building restaurant sales in-house.
