Q: What will I find in the Guides and comparisons hub?

You will find practical, how-to content that teaches the methods themselves rather than selling a service. It covers building a TDABC model from scratch, running a cost-to-serve analysis, and side-by-side comparisons such as ABC versus traditional costing or contribution margin versus cost-to-serve. Each guide is written to help you understand and apply the technique to your own data.

What is the difference between a guide and a comparison?

A guide walks you through a single method or task in sequence, for example the steps to build a Time-Driven Activity-Based Costing model. A comparison sets two approaches against each other, explaining where each one fits, what it measures and what it misses. Comparisons help you choose the right method; guides help you execute it correctly.

Do I need a costing background to use these guides?

No. The guides assume no prior expertise in management accounting. Concepts such as cost pools, cost drivers and capacity cost rates are defined as they appear, and worked numerical examples show how the calculations flow. The aim is to make accurate costing accessible to operators and managers, not only to specialists.

What is TDABC and why is it covered here?

Time-Driven Activity-Based Costing (TDABC) is a costing method introduced by Robert Kaplan and Steven Anderson in Harvard Business Review in 2004. It estimates the cost of activities using two inputs: the cost per unit of capacity (usually time) and the time each transaction consumes. It is simpler to maintain than traditional ABC, which is why it anchors most guides in this hub.
