Transaction costs are the costs of doing business with others, beyond the price itself. They include finding a partner, agreeing terms and checking that the other side keeps its part of the deal.

Types of transaction costs
- Search and information: finding partners, comparing offers and checking quality.
- Bargaining: negotiating terms and writing contracts.
- Policing and enforcement: monitoring delivery and resolving disputes.
Key factors
- Asset specificity. When an investment is tailored to one partner, that partner can exploit it, so firms need tighter safeguards or ownership.
- Frequency. Exchanges that recur often justify building dedicated rules or systems to handle them, such as a standard contract for repeat orders.
- Uncertainty. The harder it is to predict what will happen, the harder it is to write a complete contract, so more is left to trust or later negotiation.
- Trust tools. Ratings, escrow and identity checks let platforms cut these costs without owning the providers, which is how most marketplaces work.
Examples
Upwork. Upwork connects businesses with freelancers around the world. It cuts search costs with profiles, work histories and ratings, and enforcement costs by holding clients’ money for fixed-price jobs until the work is approved. Clients spent about $4.1 billion on the platform in 2023. It handles the costs that once kept firms from hiring strangers abroad.
Wise. Wise pays out from its own local accounts in each country and matches opposite flows, so less money has to cross borders. It shows its fee and exchange rate before customers pay, which removes much of the cost of comparing providers and checking hidden charges. It cuts search and information costs above all.
Frequently asked questions
What is the difference between transaction costs and coordination costs?
Transaction costs come from making exchanges, from search to enforcement. Coordination costs come from aligning interdependent work once partners are already working together.
Who came up with the idea of transaction costs?
Ronald Coase, in his 1937 paper “The Nature of the Firm”, which asked why firms exist at all. Oliver Williamson later built it into a full theory, and both won the Nobel prize in economics.
How do platforms reduce transaction costs?
By making search cheap, setting standard terms, handling payment and offering ratings and dispute handling. They move many of these costs onto the platform rather than removing them.
Why do high transaction costs lead firms to do things in-house?
When dealing with outsiders is costly or risky, owning the activity becomes cheaper. As platforms cut those costs, firms can buy more from outside instead.
