1. Three Major Fee Structures in EC Consulting

EC consulting fee structures are mainly classified into three types: "monthly fixed fee," "performance-based fee," and "hybrid." Understanding the characteristics of each and choosing the one suited to your cash flow is the key to sustainable business growth.

Fixed Monthly Fee: A format where a fixed amount (¥100K–500K+/month) is paid monthly. Suited for strategy planning, regular meetings, and long-term brand equity building.
Performance-Based Fee: A format where a percentage of sales (typically 3–10%) is paid. Effective during phases when you want to minimize initial investment, but risks compressing profits when scaling with low-margin products.
Hybrid Fee: Base fixed cost + performance fee. Adopted by many specialized agencies, this hybrid structure ensures minimum work commitment while incentivizing revenue growth.
