How do you track permit expiration dates?

Hey Guys! I am posting this to ask you all: how do you all track your permits/permit expiration dates? I'm trying to figure out how people manage all their permits (health, business license, fire safety, etc.) and remember when they expire.

Do you:

• Use a spreadsheet?
• Calendar reminders?
• Just remember / check periodically?

I've almost missed a renewal deadline twice now and I'm wondering if there's a better way. It's pretty stressful. What's working for you all? I know this must be worse for people who deal with multiple vehicles in multiple locations. Thanks so much!
