No. PaidUp is a self-help document-preparation tool. It generates a letter from the facts you provide. It is not a law firm and does not give legal advice. For advice on your specific situation — especially before filing in court — talk to a licensed attorney in your state.
Often, yes. Many unpaid invoices get paid once the other side sees a serious, written demand with a deadline — because it signals you're prepared to escalate. It also creates a paper trail you'll want if you do go to small claims court.
Email plus certified mail with return receipt is the strongest combination — you get proof it was delivered. We include a step-by-step checklist with every letter.
Escalate. Start with a firmer tier, then a final notice. If that fails, most invoice-sized disputes go to small claims court, where you usually don't need a lawyer. We point you to the right next step.
