Context

Lucena Restaurant previously relied on MenuLegal, a legacy system limited strictly to the front register. Operating without integrated stock control meant frequent ingredient spoilage and zero knowledge of the actual cost of goods sold (CMV) per dish.

The goal was to replace the fragmented stack with a unified platform connecting rapid front-of-house table service directly to dense back-office inventory intelligence and BPO routines.

Problem

01

Inventory blindness

Perishable ingredients expired unnoticed due to zero tracking between kitchen consumption and warehouse stock.

02

Hidden recipe costs (CMV)

Managers had no visibility into the true cost per dish, making margin calculations purely speculative.

03

Isolated point of sale

The legacy system (MenuLegal) functioned solely as a register, completely disconnected from back-office procurement and data.

04

Reactive promotion planning

Marketing created special deals and combos based on assumptions rather than actual surplus stock availability.

Service Architecture

Service Blueprint: From Intake to Profit

Mapped the entire "Receiving to Profit" journey connecting customer actions, front-stage touchpoints, digital systems, and backstage logistics to isolate failure points before designing UI.

Flow 03

Mobile POS Floor Service & Live Web Tracking
