Who We Are

Dedicated to making world-class cost management accessible to every business, from our home in Porto to clients around the world.

Our Story

Founded in Porto, Cost and Profitability Consulting was born from a simple vision: to bring Time-Driven Activity-Based Costing (TDABC) within reach of every business, regardless of size.

Our founders, Miguel Guimarães and Irina Costa, recognized that many SMEs and mid-market companies lacked the tools and expertise to truly understand their cost structures. They partnered to create a consulting practice that combines deep technical knowledge with pragmatic implementation methodologies.

Today, we serve businesses globally, helping them unlock profitability insights and make data-driven decisions. Our work is grounded in rigour, transparency, and genuine partnership with every client.
