Overview

Introduction

The Grand Historian records: When two feudal lords share a river, someone must decide who controls the water rights. If neither controls them, both exploit the resource carelessly. If one controls them absolutely, the downstream lord is at the mercy of the upstream one. The solution, across centuries of property law, has been negotiated price — a rate that gives both parties enough benefit to maintain the relationship voluntarily.

Internal transfer pricing is the same problem applied to amoeba management. When Amoeba A (a manufacturing unit) supplies goods to Amoeba B (a sales unit), a price must be set for that internal transaction. That price determines Amoeba A’s revenue and Amoeba B’s cost simultaneously. Set it too high and Amoeba B’s profitability is destroyed. Set it too low and Amoeba A has no incentive to supply efficiently. The price must serve both parties.

Three Methods, in Order of Preference

• Market-based pricing (preferred): The internal price mirrors what Amoeba A could obtain from an external buyer, or what Amoeba B would pay an external supplier. This is the cleanest method because it connects internal economics to real market conditions. If Amoeba A can sell externally at ¥1,000 per unit, the internal price should be at or near ¥1,000 — otherwise one party is being subsidized by the other.
• Cost-plus pricing (acceptable): Amoeba A’s verified direct costs plus a negotiated margin. Less ideal because it requires Amoeba B to trust Amoeba A’s cost reporting, and it insulates Amoeba A from market efficiency pressure. Use when no comparable external market price exists.
• HQ-fixed price (last resort): Headquarters sets the internal price by administrative decree. Administratively simple but organizationally damaging — the supplying amoeba has no incentive to improve, the purchasing amoeba has no recourse, and the price is almost always wrong because it is not updated with market conditions.

In Practice

Internal prices should be negotiated between amoeba leaders, not set by accounting. Quarterly renegotiation is typical. The negotiation itself is valuable: it forces both leaders to understand the economics of the transaction and to surface inefficiencies that neither had previously examined. A price dispute between two amoeba leaders is not dysfunction — it is the system working as designed.

Key Takeaways

• Internal transfer prices must incentivize both the supplying and purchasing amoeba.
• Market-based pricing is preferred because it connects internal units to external economic reality.
• HQ-fixed prices eliminate the accountability benefit of internal pricing — use only as a last resort.
• Price negotiation between leaders is healthy, not dysfunction.
