How do I manage limited stock during Black Friday?

As an e-commerce store owner, I'm anxious about managing inventory during Black Friday. With unpredictable demand, I need strategies to prevent overselling, maintain customer satisfaction, and maximize sales without risking stockouts. My biggest concerns are accurately tracking real-time inventory, communicating stock levels effectively, and creating urgency without disappointing potential buyers. I want a systematic approach that balances inventory management with conversion optimization during this critical sales period.
