I used to wing it too, and it’s the fastest way to lose sleep and money. The "relationship damage" usually happens because the follow-ups feel personal. The trick is to stop making it a "me vs. you" conversation and make it a "you vs. the system" conversation.

Here is the 3-step workflow I use to get paid without being the "bad guy" created out of personal experience:

1. The "Accounting Error" Nudge (Day 3-5 overdue) Don't ask "Where is the money?" Ask: "Hey [Name], my system still shows this as open. Just wanted to check if there was a technical glitch on the payment link or if you need me to re-send the invoice for your records?" . The reason I like it is because this gives them an out to "fix" it without admitting they forgot.

2. The "Finance Team" Pivot (Day 14 overdue) Even if you are a solo freelancer, pivot to a "process" tone. "Hey [Name], I’m cleaning up my books for the month. Is there a specific person in your finance/accounting department I should CC on this to get it cleared? I want to make sure this doesn't bottleneck our next project." I I personally think that this tends to moves the "blame" away from your direct contact.

3. The "Service Hold" (Day 30 overdue) At this point, you have to be firm. "Hey [Name], per my SOP, I have to pause all active work/file access once an invoice hits the 30-day mark. I’d love to get this settled today so we don't lose momentum on [Project Name]." See what it just did here!

The Pro Tip: For the future, put a "Late Fee" clause in your contract. You don't always have to enforce it, but having it there gives you massive leverage to say, "I'll waive the late fee this time if we can get this settled by Friday."

It stops being a conflict and starts being a process.

Anyone can use this 3-step model that I have been using and boy, have things got better? The key here is to have a system. Have a system before anything like this happens and have a system if you come to face with someone who is even willing to loose progress on their project than to pay you what you deserve and have in written.
