All about Activity Based Costing (ABC): get a grip on your cost structure

At a time when margins are under pressure and every percent counts, getting a grip on your cost structure is no longer a luxury, it’s a necessity. Activity Based Costing, also known as ABC costing, helps you understand exactly where your costs come from. Instead of guesswork and global markups, you get real insight into what a customer, product or project costs you.

In this blog we clearly explain what Activity Based Costing is, why it is important right now, and how you can apply or outsource this method smartly without diving deep into the data yourself.

What is activity-based costing and what makes it different?

What exactly is activity-based costing? Activity Based Costing (ABC) is a method by which you accurately allocate indirect costs to products, customers or services. This is done based on activities that are actually performed within your organization.

Activity-based costing meaning

Activity Based Costing meaning: a costing method in which costs are allocated based on activities (such as order processing, assembly, support) rather than generic markup rates.

Difference with traditional cost allocation

Traditional methods often allocate indirect costs based on direct hours or turnover. ABC, on the other hand, links costs to real process steps and makes visible where you are working inefficiently or incurring losses.

When do you apply ABC?

  • If you provide multiple products or services with different process complexity
  • If you suspect your margins are wrong
  • If you want to strategically drive profitability by customer or segment

Link with strategic insight

ABC helps not only with cost control, but especially with strategic decision-making. Consider pricing strategies, customer selection or investments in automation.

How does ABC costing work? Explained in 4 practical steps

The ABC method is practically applicable in any type of organization, from manufacturing company to service provider. Below we explain the four basic steps.

1. Identify activities

Determine what activities take place within your organization. Examples:

  • Making quotations
  • Customer Service
  • Purchasing and logistics
  • Project Management

2. Assign costs to activities (cost drivers).

Collect costs associated with these activities, such as salaries, software licenses, or transportation. Link these to so-called cost drivers, such as number of customer inquiries, number of shipments, or project hours.

3. Charge costs to products/services

Based on the consumption of activities per product or customer, costs are allocated. This allows you to discover what a product really costs and which customers are profitable.

4. Analyze and interpret the results

With these insights, you can make strategic decisions: adjust rates, improve processes or make choices in your customer portfolio.

Activity-based costing example: this is what it looks like at an SME

A real-world activity-based costing example: an SME manufacturing company supplies three product lines. The costs for support, packaging and logistics were previously divided evenly. After introducing ABC, it turned out:

  • Product A had a much higher support requirement than the rest
  • Logistical costs were extreme for Product C due to different format
  • Product B, previously seen as least profitable, actually turned out to be the most efficient

What did this yield?

  • Product A received a higher selling price
  • Product C was phased out
  • Product B received additional marketing budget

Without ABC, these insights would never have surfaced.


Why outsourcing is smart: focus on your business, we focus on your numbers

Activity Based Costing sounds logical, but in practice it is quite complex:

  • You need good data and structure
  • Knowledge of cost drivers and financial models is needed
  • Interpretation determines success

That’s why many SMBs and scale-ups choose to outsource ABC.

Frequently asked questions about ABC Costing

What are the 5 steps in Activity-Based Costing?

The five steps are:

  1. Identify activities within the company
  2. Assign costs to each activity
  3. Determine the cost drivers for each activity
  4. Divide activity-related costs among products/services
  5. Analyze outcomes and use them for decision-making

A manufacturing company discovers through ABC that one product requires a lot of customer service and is therefore loss-making. After analysis, they raise the price or discontinue the product. This leads to profit optimization.

An activity cost could be, for example, processing a customer order. Consider employee time, software use, and administrative costs per order.

Traditional costing often allocates costs based on direct hours or revenue. ABC, on the other hand, looks at specific activities and cost drivers, allowing for much more precise allocation and better decision-making.
