Why Cash On Delivery Requires Specialized Unit Economics
1. Confirmation Drop-off
In COD, up to 15-30% of placed leads cancel or give fake phone numbers during the confirmation call. You pay ad costs on every lead, but only confirmed orders ship.
2. The RTO Double-Penalty
When a buyer refuses a parcel, you lose the outbound shipping fee, pay a return courier fee, and forfeit the acquisition ad spend with zero collected revenue.
3. Remittance Cash Gap
Couriers hold collected cash for 7 to 21 days before paying out. Without accurate float modeling, businesses run out of working capital even when technically profitable.
