Quick Answer: Singapore businesses receive 35-45% of customer inquiries after 6pm—when no one is available to respond. A single missed WhatsApp message at 10pm represents SGD 150-800 in lost revenue depending on your industry. AI automation captures these inquiries instantly, converting them into bookings, sales, and qualified leads while you sleep.
Your team goes home at 6pm. Your customers pick up their phones at 10pm. That gap between office hours and customer activity is costing you more than you realize.
This is not about working harder or hiring night staff. It is about understanding when your customers actually make decisions—and being there to capture that moment.
