Pull up Seller Center. Compare what FBT says you have against what you've shipped in, minus what you've sold. The numbers don't match. They almost never do — we audit FBT accounts every week and have yet to find one with zero discrepancies.
The question isn't whether your counts are off. It's where the units went, whether TikTok owes you for them, and whether you're still inside the window to collect.
The four places FBT inventory disappears
FBT runs your inventory through 14+ US fulfillment centers, largely operated by subcontracted 3PLs. Every handoff in that chain is a place units can vanish:
1. Receiving. You shipped 500 units; the warehouse checked in 480. Nobody flags it — your inventory simply starts 20 units lighter than your invoice says it should. Receiving shortfalls are the discrepancy sellers discover last, because the missing units were never in Seller Center to begin with. (Protecting yourself at inbound.)
2. Storage. Units get damaged, misplaced, or miscounted inside the warehouse. Sometimes they reappear as "damaged" in your counts; sometimes they just evaporate between one snapshot and the next. That's shrinkage, and it accumulates quietly.
3. Outbound. Wrong item or wrong quantity shipped to a customer. The customer gets refunded, and the unit that left your stock incorrectly is your loss unless it's claimed.
4. Returns processing. The leakiest stage of all. A customer return should either re-enter your sellable (or damaged) inventory or trigger a reimbursement. Returns that do neither — vanished returns — are the single most common leak we find in FBT accounts. (What actually happens to FBT returns.)
"Doesn't TikTok reimburse this automatically?"
Partially — and the gap between "partially" and "fully" is where your money is.
On paper, the coverage is seller-friendly: FBT logistics issues are covered up to the item's total retail value, and units that can't be restocked after a return are supposed to auto-reimburse. In practice, the automation catches the clean cases. Receiving shortfalls, storage shrinkage, and vanished returns are not auto-detected. No alert fires. No line item appears. Those units are reimbursable only if you find the discrepancy and file the claim.
And the clock is brutal: FBT logistics-related claims are due 60 days from the order creation date — not from delivery, not from when you noticed. A seller who reconciles quarterly is donating the oldest two months of discrepancies to TikTok, permanently. (The full deadline cheat sheet.)
What discrepancies actually cost
The benchmark across fulfillment networks is a leak of 1–3% of GMV for unaudited accounts. FBT skews toward the painful end of that range for two reasons: the subcontracted 3PL structure means handling quality varies by facility, and FBT is young enough that most sellers aren't auditing at all.
Concrete numbers: a shop doing $50K/month through FBT is plausibly leaking $500–$1,500 monthly. One brand we audited recovered $30,800 in a single month — that's how much had piled up undetected. A supplement brand recovered $13,900 in February 2026. Neither had any idea the money was missing, because discrepancies don't announce themselves. That's the whole problem.
What to do about it
At a high level: reconcile monthly — shipped versus received, inventory movement versus sales, returns versus restocks-or-reimbursements. Keep your manufacturer invoices organized, because they establish unit value when you claim; sellers without invoices get reimbursed at whatever value TikTok assigns. File discrepancies through Seller Center (FBT Issue → Logistics-Related Reimbursement Claims) inside the 60-day window, and track approved claims through to your settled statement — approved reimbursements typically post within ~5 business days, and approved is not the same as paid. (Step-by-step claims guide here.)
Doing this well, every month, forever, is the hard part. Miss a month and the 60-day window eats your oldest claims.
Or let us find them
This is literally all we do. Free 24-hour audit of your FBT account — receiving shortfalls, shrinkage, vanished returns, unclaimed reimbursements. We file everything within TikTok's ToS and take a percentage only of what we actually recover. If your counts match perfectly, the audit costs you nothing and you sleep better.
FAQ
Why doesn't my FBT inventory match what I shipped? Units go missing at receiving, in storage, at outbound, and in returns processing across FBT's subcontracted 3PL network. Discrepancies are normal — unclaimed discrepancies are the expensive part.
Does TikTok automatically reimburse missing FBT inventory? Only the clean cases, like returns that can't be restocked. Receiving shortfalls, shrinkage, and vanished returns are not auto-detected and require a seller-filed claim.
How long do I have to claim an FBT inventory discrepancy? 60 days from the order creation date for FBT logistics-related claims, filed via Seller Center under FBT Issue → Logistics-Related Reimbursement Claims.
How much is missing FBT inventory worth in reimbursements? Covered logistics issues reimburse up to the item's total retail value. Unaudited accounts typically leak 1–3% of GMV; keep manufacturer invoices on file to protect your valuation.
