Dear [Client’s Name],

This is a formal demand for payment of $500 USD for services I completed for you during the week of [insert dates].

As agreed, I performed the work and dedicated my time to your project. The results you expected were pending because we were awaiting responses for support, which was outside my control. Regardless, I fulfilled my obligations as an independent contractor.

Please note:

        •        Under US and international contract principles, payment is owed for services rendered even in the absence of a written contract, as long as there is evidence of an agreement (emails, messages, invoices, and work records).

        •        Failure to pay constitutes a breach of contract.

        •        If this payment is not received by [insert date – give 7 calendar days], I will have no choice but to pursue further action, including:

        •        Filing a complaint with the Better Business Bureau and other online platforms.

        •        Reporting the unpaid invoice to the IRS and state labor authorities (as US tax law requires accurate reporting of contractor payments).

        •        Sharing documentation of this matter in professional networks where your reputation and business credibility may be impacted.

I would prefer to resolve this matter quickly and amicably. Please arrange payment of $500 via [your preferred payment method] no later than [date].
