Bridgeworks Co., Ltd. — New Platform Launch Story

From Excel-based P&L management to Built in-house from scratcha management dashboard.

PLBoard is a management platform that automatically aggregates P&L from project results and labor-cost data. Revenue, cost, gross profit, and operating profit can be viewed from multiple angles by customer, SV, and department—anytime.

This is the launch story of how on-the-ground challenges—“monthly P&L closing takes days, costing depends on individuals, and profitability can't be viewed from multiple angles”—were solved with a new cloud platform built in-house from scratch.

CLIENT
About the Client

Bridgeworks, an IT-services company that runs multiple business lines.

With multiple business segments such as SI, infrastructure, and QA, the company delivers numerous customer projects through a structure of several departments and supervisors (SVs). Accurately matching each project's revenue with its costs—labor costs above all—is the prerequisite for sound management decisions.

Project management relied on the external ERP “ZAC.” Reconciling the project and performance data accumulated there with per-SV payroll data, and making profitability visible by customer, department, and segment, was the key to improving margins.

CHALLENGE
Design challenges to solve

Profitability—accurate, multi-angled, and fast.

Not a technical problem, but a challenge tied directly to profitability and the speed of management decisions. The new platform had to solve both at once.

Grasp P&L in real time, and you can act faster
Manual Excel closing of monthly P&L caused a multi-day lag.
Accurate data import raises the reliability of the numbers
ZAC and payroll data suffered errors and omissions from manual transcription.
View profitability across multiple axes to pinpoint what to improve
Customer-, department-, and segment-levelHard to aggregate, so overall optimization was impossible
Automating costing eliminates dependence on individuals
Costing logic had become a person-dependent black box.

ARCHITECTURE
The architecture we built together

From import to visualization, on a single platform.

From importing project results and labor costs to cost calculation, multi-axis P&L aggregation, and dashboard visualization—all unified on a single platform built in-house from scratch. Imported data flows straight into costing, and P&L becomes instantly visible by customer, SV, department, and segment.
