If your FBA cost-per-unit crept up over the last four quarters and you cannot point to a single line item, the Inbound Placement Service fee is a likely culprit. It is quiet, it is bundled into your settlement reports, and it is the single largest new FBA cost operators misread as “just higher fulfillment fees.” With Prime Day prep timelines compressing in Q2 and tariff pressure squeezing landed cost, this is the fee to audit next. This post is for Amazon operators who send inventory into FBA every month and want a clear playbook to cut that line without changing their IPI score or rebuilding their supply chain from scratch.
What Happened
Amazon rolled out the Inbound Placement Service fee in March 2024. The fee applies when you send inventory to fewer fulfillment centers than Amazon’s distribution model recommends. You pick one of three shipment split options at the inbound workflow step, and each option prices differently per unit.
The three options are Minimal Shipment Splits, Partial Shipment Splits, and Amazon Optimized Shipment Splits. Minimal ships everything to a single receive center and carries the highest per-unit IPS fee. Partial splits your cartons across two to three regions at a mid-tier fee. Amazon Optimized splits across four to eight FCs and can drop the IPS fee to zero for standard-size units. The per-unit fee ranges roughly from $0.21 on the low end for small standard items shipped optimized to north of $1.58 for large standard items shipped minimal. Oversize is even higher.
The fee applies to every eligible unit on every inbound shipment. If you send 10,000 units per month and default to Minimal, that is real money leaving your margin every four weeks. Reference: Amazon’s FBA Inbound Placement Service fee documentation and the April 2024 FBA fee update.
Why This Matters for Operators
Run the math on your own account. Pull your last 90 days of Inbound Shipment data from Seller Central, filter by shipment plan, and compare per-unit placement cost by option. We consistently see mid-market brands paying 60 to 120 basis points of net revenue in IPS fees alone. That is margin that does not come back through better SEO, better ads, or better pricing.
The compounding effect matters more. IPS fees hit at the same moment as:
- Higher storage fees during Q3 and Q4 when Prime Day and holiday inventory lands
- Peak season surcharges from parcel carriers on FBM overflow
- Elevated landed cost from ongoing tariff pressure on China-origin goods
Operators running on thin margin cannot absorb three or four of these at once. Cutting IPS is one of the fastest levers because it does not require renegotiating carrier contracts, reformulating pricing, or chasing a new channel. It is a workflow decision at the moment of shipment creation.
What Most Brands Get Wrong
Three misreads cost operators money every week.
First, defaulting to Minimal because it looks simpler. One label, one truck, one receive center. The shipment creation feels easier. The fee is up to 6x the Optimized rate. Simplicity at the inbound step creates a recurring per-unit tax on everything you sell through FBA.
Second, assuming the only fix is doing it yourself. Brands hear “split your shipments” and picture writing their own label allocation logic, paying LTL to four destinations, and coordinating with a warehouse that is not set up to do it. Most 3PLs built for FBA prep already have regional outbound rates and can split a master pallet across Amazon Optimized destinations for a fraction of what the IPS fee costs.
Third, conflating IPS with IPI. These are different mechanisms. IPI is a capacity/health score that caps your storage. IPS is a per-unit fee on how your inbound ships. Fixing one does not fix the other. We keep seeing operators who tightened their IPI to 500+ assume they handled everything and ignore IPS entirely.
What You Should Do Next
Prioritized by impact.
- Audit your IPS spend for the last 90 days. Pull the “Inbound Placement Service Fees” line from your FBA fulfillment fee report. Calculate it as a percentage of your FBA revenue. If it is above 0.5%, you have meaningful room.
- Default every new shipment to Amazon Optimized for standard-size SKUs with velocity over 30 units per week. These SKUs will recover the split cost fastest through fee savings.
- For slow-moving or oversized SKUs, model Partial vs Optimized. The Optimized splits sometimes route units to FCs that do not match demand. Partial can be the right call for long-tail inventory.
- Move case-packed inbounds, not eaches. Palletized, case-packed inbound shipments receive lower IPS rates because Amazon can cross-dock them faster.
- Use an upstream 3PL or Amazon Warehousing and Distribution (AWD) to do the regional split before it hits FBA. You pay outbound freight from the buffer but eliminate IPS on the inbound side. For brands shipping over 5,000 units per week, this nearly always wins.
- Rebuild your inbound SOP. Document which option to pick by SKU tier, who approves deviations, and who audits the fee each month. Without a written SOP, shipment creators pick whatever the UI defaults to.

FAQ
What is the Amazon Inbound Placement Service fee?
It is a per-unit fee Amazon charges when you send FBA inbound inventory to fewer fulfillment centers than the system’s distribution model suggests. It applies on top of standard FBA fulfillment fees and was introduced in March 2024.
How is IPS different from IPI?
IPI (Inventory Performance Index) is a score that controls your FBA storage capacity. IPS (Inbound Placement Service) is a fee charged on every inbound unit based on how you split the shipment. Different levers, different mechanisms.
How much can I save by switching to Amazon Optimized splits?
For standard-size units the IPS fee can drop to zero on Optimized, compared to $0.21 to $1.58+ on Minimal. Most operators we audit save 20 to 40 percent of their IPS spend by moving their top-velocity SKUs to Optimized.
Does splitting shipments slow down receive times?
It can, but in practice Amazon Optimized splits often check in faster per shipment because each destination FC receives a smaller volume. The net receive-to-live timeline is usually similar or faster.
Do I need a 3PL to cut IPS fees?
Not always. If your volumes are below 3,000 units per week and your SKU count is tight, you can configure Optimized splits yourself from Seller Central. Above that volume, a 3PL or AWD usually pays for itself because the splitting happens upstream and you get clean palletized inbounds.
Conclusion
The Inbound Placement Service fee is one of the fastest margin recoveries available to Amazon operators in Q2 2026, and it does not require rebuilding anything. Pull your 90-day IPS spend, switch your top SKUs to Optimized, and build an SOP so the workflow does not slip back.
