```python
from typing import List, Tuple

def sum_product(numbers: List[int]) -> Tuple[int, int]:
    total_sum = sum(numbers)
    total_product = 1  # Initialize product to 1
    for number in numbers:
        total_product *= number  # Multiply each number to total_product
    return total_sum, total_product  # Return a tuple containing the total sum and total product
```
