There are 3 root-cause bugs across the codebase (causing 6 test failures):

1. utils.py — calculate_total() does arithmetic on a string tax_rate without converting to float
2. utils.py — normalize_name() crashes on None input (no null check)
3. models.py — Invoice.summary() references self.total (method object) instead of self.total() (method call)

pip install -r requirements.txt
pytest -v

Expected: 10 tests, 6 failures before fixes, 10 tests, 0 failures after.
