Peak Season Capacity Planning — What a Warehouse Builds in Advance, From Chuseok to Year-End

Peak season isn't a surprise — it's an exam with a printed date. The wave calendar of Korean logistics, splitting capacity into four resources to find the bottleneck, back-computing headcount from standard time and the ceiling the 52-hour workweek puts on the overtime card, the 85% occupancy wall and the overflow ladder, process cards that change the flow before you buy more of anything, and how not to sell peak capacity for free.

From Cost to Price — Connecting Rate Cards, Contracts, and Profitability to Cost

Cost is not a price — it's a floor and it's leverage. How to rewrite the rate card as a translation of cost structure, why across-the-board increases drive away your best customers, the price waterfall between list rate and pocket price, turning the ledger into renewal-negotiation evidence, writing assumptions instead of numbers into quotes, and the treatment ladder for the whale curve's tail. Part 5 of our logistics costing series — the finale.

Variance Analysis and Cost Control — How to Read Cost in Three Sentences a Month

A variance isn't the end of a calculation — it's the start of a sentence. The illusion flexible budgets strip away, the activity matrix where offsets hide, the warehouse-shipper-market three-way split, three thresholds for choosing which variances to investigate, why favorable variances deserve suspicion, and the discipline of treating standards as consumables. Part 4 of our logistics costing series.

Cost Drivers and Standard Time Design — How Do You Measure Time in a Warehouse?

Choose drivers by causation, not correlation. And a standard time isn't a number — it's an equation. The cross-subsidy that aggregation error creates between shippers, designing time equations, picking where travel is half the clock, ledger regression as the method only a warehouse can use, and the 2026 shift from sampling to full observation. Part 3 of our logistics costing series.

Activity-Based Costing — Whose Cost Was That, Exactly?

Revenue-proportional allocation will never find an unprofitable customer. It was built that way by definition. The two-stage path from resources to activities to shippers, the unused capacity you must not allocate, the whale curve, and why ABC failed once but works in a warehouse. Part 2 of our logistics costing series.

Costing Storage — What One Pallet, One Day Is Actually Worth

Storage cost is decided by the denominator. Divide by effective operating positions, not gross floor area, and expose the asymmetry of building for peak while billing at average as a volume variance. The five billing units and whose interest each serves, honeycombing, and what 37% cold-storage vacancy means for a standard cost in 2026.

Understanding Standard Costing in Logistics — What Should One Order Cost?

Logistics cost isn't something you count at month-end. It's something you set in advance. How to build a unit cost from standard time × standard rate, split the gap from actual into rate, efficiency, and volume variances, and what's reshaping cost calculation in 2026. Part 1 of our logistics costing series.
