ZenTech · Case study № 1 · Waffleish 🧇

The queue was eating their weekend. We made it disappear.

Waffleish is a weekend waffle kitchen run from a converted garage — bubble waffles, boba, a queue out the gate. Their "online ordering" was a WhatsApp inbox answered between bakes. We watched three customers look at the line and walk away in one afternoon.

This one isn't a mockup — the system below is in production, right now.
The problem

Every order lived in someone's head.

Orders arrived three ways at once: shouted at the till, typed into WhatsApp, relayed from memory. The kitchen ran on paper scraps. WhatsApp messages sat unanswered for forty minutes because everyone was elbow-deep in batter — and when the reply finally came, the order sometimes came out wrong anyway.

The queue wasn't a sign of success. It was a leak — every fifth person looked at it and left.

Nothing about the waffles was broken. The information was broken: no single place where an order existed, no way for a customer to know their food was ready, no way for the owner to know what actually sold.

What we shipped

One source of truth, from phone to hand-over.

Customers

Scan → order → skip the queue

A QR poster at the gate opens the menu on their phone. No app, no signup. They order, get a number, and watch it live — queue position, wait estimate, then a READY buzz.

  • Pre-orders with pickup slots
  • Every 10th waffle free, automatically
  • One-tap rating after collection
Kitchen

Stations instead of paper

Each staff phone logs into its own station and sees only its own work. The baker never guesses toppings; the caller physically cannot call an order that isn't finished.

  • Orders age amber → red so nothing gets forgotten
  • New work arrives with a chime
  • Undo for every fat-finger
The crowd

A TV board like the big chains

Any old TV or tablet shows numbers marching from Being made to Ready — collect! with a flash and a ding. A garage suddenly feels like a franchise.

  • Runs in any browser, zero hardware cost
  • Owner dashboard: live sales, top sellers, sold-out toggles
  • Weekend digest delivered automatically
