How do I prevent overselling firearms online and in-store?

Overselling happens when a firearm sells in-store while still listed as available online — or vice versa. The only reliable prevention is real-time, bi-directional inventory sync between your POS and your online store. When a serialized firearm sells at the counter, it must be immediately removed from your online listings. A disconnect of even a few minutes creates customer service problems and potential compliance issues.
