Answer:
The answer is: Longer lead times and they can be inventoried.
Step-by-step explanation:
Physical goods or products usually have longer lead times than services (although not necessarily) but the main difference between them is that they can be inventoried.
For example, a company that produces chairs can produce chairs during the week and then store them in a warehouse. But if a hotel only rents 30 of its 50 available rooms today, it cannot rent 80 rooms tomorrow, only 50. A service by definition cannot be inventoried, or stored for later use.
