We do not sell subscriptions or packaged software. Fees reflect plant complexity, evidence quality, and how many variance families (material, labour, overhead) sit in scope.

Indicative ranges

Material usage & scrap review

From HKD 28,000

One to two weeks for agreed material families at a single plant. Higher when BOM history is incomplete or scrap coding is inconsistent across shifts.

Labour rate & efficiency check

From HKD 32,000

Priced mainly by work-centre count and whether temporary labour and overtime need separate bridges.

Overhead & inventory variance probe

From HKD 38,000

Two to three weeks depending on absorption logic and the volume of inventory adjustment journals to sample.

Full manufacturing variance audit

Typically HKD 85,000–160,000

Fixed fee after scoping. Single-line plants with clean scrap records sit toward the lower end; multi-line plants with weak BOM controls sit higher.

What moves the estimate

  • Number of work centres and depth of BOM levels
  • Quality and completeness of scrap, rework, and time tickets
  • Whether standards changed mid-period without a clean cut-over
  • Need for bilingual reporting (English / Chinese) for board packs
  • Travel beyond the Kwun Tong–New Territories corridor

What is not charged separately

Kick-off calls, draft workshops, and one revision cycle on the final report are included in the fixed fee. Extra plant days requested after fieldwork closes are billed at an agreed day rate stated in the engagement letter.

Deposits

A 30% deposit confirms the fieldwork dates. The balance is due on delivery of the final report. See our refund policy for cancellation and rescheduling rules.
