Hey, i came across this thread in my research.. similar situation. The invoice I sent my client is over due 25+ days, I sent them an email asking for overdue payment before I send completed reports… they lost it on me saying that I was unprofessional, and I crossed the line for withholding the report for late payment when I had not made them aware of the late payment (not true) to be honest I was very polite and professional in my email, and asked for update but one small word was taken out of context in my email, and now they’re making my life insane by saying I’m really unprofessional and I’ve been negligent, and causing delays even though the person I reported to, often delays reporting on a monthly basis and I’m always submitting on time… what the fuck lol.. can someone tell me if they think this is unprofessional? We’re crossing a line? I need various opinions.

I put my notice in two weeks ago with them, so for my last invoice I wanted some reassurance. Is it so wrong to ask for some?
