Your 3PL ships to Amazon. Some of it never arrives.
Sell on Shopify and Amazon through a 3PL, and two costs pile up unseen: units your 3PL sends to FBA that Amazon never checks in, and stockouts from late inbound. The tools watching your FBA levels can't see your 3PL side. Pulse watches both.

Units your 3PL ships that Amazon never checks in
Roughly 1 in 5 FBA inbound shipments arrives short. Every missing unit is money Amazon owes you, but the claim needs proof from the shipping side: the bill of lading, the packing list, the carton counts. Your 3PL has all of it. Amazon-only tools do not.

Stockouts caused by late inbound, not slow sales
A two-week FBA stockout runs $10,000+ in lost sales, plus the ranking and Buy Box you spend weeks clawing back. It usually starts with a late 3PL inbound. Pulse catches that late shipment and ties it to the channel it's about to stock out, so you hear about the cause, not just the symptom.
Every other tool sees one side. Pulse sees both.
Reimbursement tools can spot a short receipt and file the claim, but only from Amazon's side of the count, which Amazon can dispute. Your 3PL's portal stops at the warehouse door. Pulse follows the same units across both and brings the 3PL's own proof, the bill of lading and packing list, so a short shipment holds up as a claim and a late one becomes an alert before it stocks you out.
