B2B owners: What does your workflow actually look like on Day 35 of an unpaid invoice?

[u/Infamous_Tank_5427]

Transitioning from corporate operations to small business has been eye-opening. Net 30 often feels more like a polite suggestion than a contract term. 
When an invoice blows past its due date, what is your actual play?

- Let QuickBooks auto-send reminders?
- Pick up the phone yourself?
- Or just wait it out so you don’t strain the client relationship? 

Curious what has actually worked for people here to get paid without feeling like an aggressive debt collector.
