- How to understand backward integration: controlling the supply chain and use it for your capital strategy
- How to understand forward integration: distribution & customer contact and use it for your capital strategy
- How to understand asset-light vs. asset-heavy models and use it for your capital strategy
Transaction cost theory according to Coase and Williamson
Ronald Coase revolutionized economic theory in 1937 with a simple question: Why do companies exist? Answer: BecauseTransaction costsconsist. Oliver Williamson expanded on this in 1975 and defined when companies should produce internally (integration) and when they should buy from the market.
The key question is not “Can we do it?” but"What is the break-even between internal costs (overhead, risk, complexity) and external costs (negotiation, monitoring, dependency)?"
Backward Integration: Controlling the supply chain
Backwards integrationmeans buying your suppliers or building in-house. You reduce dependence on external partners, control quality and possibly costs.
- Advantage: control, secrecy, potentially lower costs at scale
- Disadvantage: capital intensity, risk, loss of flexibility
- Best for: High-volume, standardized inputs
"Vertically integrated companies are cumbersome. They can't react quickly. But if you have a cost advantage - e.g. raw materials - it's overwhelmingly profitable."
– Michael Porter, Competitive StrategyForward Integration: Distribution & Customer Contact
Forward integrationis the opposite: you build your own sales channels or retailers. Classic example: Manufacturer opens flagship stores.
- Advantage: Direct customer contact, data ownership, branding
- Disadvantage: High capital requirement, operational risk, dist. is complex
- Best for: Branded consumer goods, premium positioning
Asset-light vs. asset-heavy models
This is the key decision for investors. Asset-light models (outsourcing, platform) were the favorite from 2010-2020. You have:
Example asset light:Uber (drivers are contractors, cars are external) vs.Asset Heavy:Taxi company (drivers employees, cars in-house).
However: 2020-2024 trend back toStrategic Integration– only outsource core competencies, control critical assets (supply chain risk!).
The Deutsche Post StreetScooter Case
2014:Deutsche Post bought StreetScooter (e-van manufacturer) → backward integration to control their supply chain.
- Strategy: Reduce shipping costs by using your own electric vehicles
- Result: quality problems, technology mismatches, culture clashes
- 2022: Sale of the company – integration failed
Teach:Backward integration only works if you have real synergies. Deutsche Post had sales reach, but no automotive expertise. A classic trap.
Coca-Cola Bottling: The successful apprenticeship
On the contrary:Coca Colais a masterpiece of selective vertical integration:
- Kern:Coca-Cola focuses on formulation, branding, concentrates
- Forward Integration:Partnerships with local bottlers (often own investments)
- Strategischer Kontakt:Just enough control to ensure quality, not so much that overhead increases
That is"Pseudo-integration"– enough control for quality, little capital expenditure. And the bottlers can innovate more quickly (new drink categories).
Make-or-buy frameworks for investors
At theDue diligenceInvestors evaluate make-or-buy decisions based on:
- Strategische Kritikalität:Is this a core competitive advantage? (VRIO-Analyse)
- Marktgegebenheiten:Are there reliable external partners?
- Kapitalanforderungen:Can the company finance the integration?
- Managementfähigkeit:Does the team have experience with both?
- Exit-Sicht:Does integration make exit more expensive/easier?

- Porters Five Forces– to evaluate supplier power
- Wertschöpfungskette nach Porter– where do costs arise?
- M&A Prozess– Integration as a strategic acquisition
Financing implications
Asset-heavy integration requires: → Higher debt ratios (asset as security) → Longer break-even times → Lower VC appeal (PE prefers asset-heavy)
