Business partner stopped communicating mid-contract

What we told them

Keep performing, and document everything. Silence is not termination, and if you stop first you hand them a breach argument. Send one written notice that states the outstanding obligations, a reasonable deadline and what happens if it passes — delivered by a method that produces proof. Most silence is distress, not malice: people who cannot pay stop answering the phone. The notice either restarts the conversation or gives you a clean record to act on.
