Here's a basic sequence diagram representing the interaction sequence when a utility company sends a bill to a customer:
```
Customer -> Utility Company: Request bill
Utility Company -> Billing System: Generate bill
Billing System -> Utility Company: Return generated bill
Utility Company -> Customer: Send bill
```
In this sequence:
- The customer requests the bill from the utility company.
- The utility company generates the bill using its billing system.
- The billing system returns the generated bill to the utility company.
- Finally, the utility company sends the bill to the customer.
