Small business owners.. How do you actually keep track of your BIR compliance? (Not filing, but the daily record-keeping before filing)

Question sa mga may sariling business without a bookkeeper or CPA.

Pag dating ng filing deadline, paano kayo nag-prepare? Organized ba records niyo or last-minute panic mode?

Specifically:

1. How do you track your daily sales and expenses? (Notebook? Excel? App?)
2. When you get a letter from BIR, do you understand it right away or do you ask someone?
3. Have you ever been penalized for missing docs or wrong forms?
