A quiet nudge
Assume they missed it, not that they’re avoiding you.
Hi Alex — circling back on the invoice from March 4 ($240). I haven’t seen the payment yet. Easy to miss; this is just a nudge.
Overdue invoice / payment reminder
The invoice already went out. This is not that first notice. You’re only saying it still hasn’t been paid.
Name the old invoice date and the amount still open.
Still open
Give them this week. Don’t invent a late fee.
The $95 from Thursday is still open. When you get a chance this week is fine — just flagging it so it doesn’t sit.
Past due, check the email
Sometimes it landed in the wrong inbox.
Friendly reminder: invoice from the 12th is past due. Total $180. Tell me if it went to the wrong email.
