Amazon Inventory Placement Service vs Distributed Inventory in 2026

Every FBA seller faces the same decision when creating an inbound shipment: send everything to one fulfillment center and pay Amazon to redistribute it, or split the shipment yourself across multiple locations and pay nothing in placement fees. The first option is Amazon's Inventory Placement Service. The second is distributed inventory placement, which Amazon calls "Amazon-optimized splits."

Neither option is universally better. The right choice depends on your shipment volume, product size tier, freight costs, and how much operational complexity you can absorb. This guide breaks down the actual numbers for 2026 so you can make that decision with real data instead of guesswork.

How Each Placement Option Works

Amazon gives you three choices when you create an FBA inbound shipment. Each one determines where your inventory goes and what you pay to get it there.

The first option is Amazon-optimized splits (distributed placement). Amazon assigns your shipment across 3 to 5 or more fulfillment centers based on forecasted demand. You ship to each location. There is no placement fee. You pay only your outbound freight to each destination.

The second option is minimal splits. Amazon reduces the number of destinations to 1 or 2 locations. You pay a per-unit placement fee for the convenience of fewer shipments. After the January 15, 2026 fee increase, minimal splits cost roughly $0.27 to $2.30 per unit depending on product size.

The third option is Inventory Placement Service (IPS), sometimes called partial placement. You ship everything to a single fulfillment center. Amazon handles all redistribution. This carries the highest per-unit fee, starting at $0.30 for small standard items and climbing past $1.58 for large standard products.

"Used IPS to send to a single FC near my top markets. Sales jumped 35% in two weeks because I stopped losing Prime orders to slow delivery. The $0.45 per unit fee paid for itself within days."

2026 Fee Comparison by Size Tier

The cost difference between placement options is significant and scales with volume. Here is what each option costs per unit in 2026, broken down by product size tier.

Size Tier	Optimized Splits (Distributed)	Minimal Splits	IPS (Single Location)
Small Standard (under 1 lb)	$0.00	$0.27 - $0.32	$0.30 - $0.40
Large Standard (1 - 3 lb)	$0.00	$0.40 - $0.68	$0.68 - $1.06
Large Standard (3+ lb)	$0.00	$0.68 - $1.58	$1.06 - $1.58
Large Bulky	$0.00	$1.30 - $2.30	$1.58 - $2.30+

For a concrete example: a seller shipping 5,000 units of a large standard product (2 lb) would pay $0 in placement fees with optimized splits, roughly $2,000 to $3,400 with minimal splits, and $3,400 to $5,300 with full IPS. That gap widens every time you restock.

These fees increased on January 15, 2026 by approximately $0.05 per unit for minimal splits. Amazon has raised placement fees in each of the last two years, and sellers tracking the data report an average 9.2% increase from Q4 2025 to Q1 2026.

"Split placement killed my velocity. One pallet in Texas, another in New Jersey. The buy box started tanking because Amazon prioritizes local stock. I paid $2k extra in inbound shipping to fix it."

The Hidden Cost of Distributed Placement

Distributed placement is free in terms of Amazon fees. It is not free in terms of operational cost. Sellers who choose optimized splits need to account for several expenses that do not show up on the placement fee line.

• Freight to multiple locations. Instead of one shipment to one fulfillment center, you are sending 3 to 5 separate shipments. Each one has its own freight cost, whether you are using LTL, parcel, or a prep center.
• Prep and labeling complexity. Each split shipment needs its own labels, box content information, and carrier coordination. If you use a prep center, they typically charge per shipment, not per unit. More shipments means higher prep costs.
• Receiving delays. Amazon receives shipments at different speeds across different fulfillment centers. A split shipment might have 3 of 5 pallets received within a week while the other 2 sit in receiving for 2 to 3 weeks. Your inventory is partially available for sale during that window.
• Stranded inventory risk. When Amazon assigns small quantities (sometimes as few as 10 units) to low-demand fulfillment centers, those units can sit unsold for months. You pay monthly storage fees on inventory that generates no revenue.

One seller on Reddit described the stranded inventory problem this way:

"Let Amazon split 2,000 units nationwide. 40% ended up stranded in low-demand FCs in Nevada and Iowa. PPC costs went through the roof trying to compete. Manually reassigned everything. Took three weeks and $3k in fees."

The lesson is that "free" placement is only free if your freight costs stay low and Amazon does not scatter your inventory into dead zones. For sellers with lightweight, small standard products, distributed placement often makes sense because the freight difference is manageable. For sellers with heavy or bulky products, the freight cost of shipping to 5 locations can exceed the IPS fee of shipping to 1.

When IPS Pays for Itself

Inventory Placement Service makes financial sense in specific scenarios. The fee is a known, predictable cost. The savings come from reduced freight, simpler operations, and faster inventory availability.

IPS tends to work well when:

• Your products are heavy or bulky. Freight cost per pound to 5 locations can exceed the per-unit IPS fee when your items weigh more than 3 lb.
• You ship in high volume. Consolidating a 10,000-unit shipment into one outbound load saves on freight, prep, and carrier coordination even after paying $0.40 to $1.00 per unit in IPS fees.
• Speed to available inventory matters. One shipment to one FC means one receiving window. Split shipments create 3 to 5 receiving windows, and the slowest one determines when your full inventory is live.
• Your prep center charges per shipment. If your 3PL or prep center charges $150 per outbound shipment, 5 splits cost $750 versus $150 for a single IPS shipment. That $600 difference offsets IPS fees on shipments under roughly 2,000 units.

IPS does not make sense for lightweight, small standard products shipped in moderate quantities (under 1,000 units). In those cases, freight to multiple locations is cheap, the IPS per-unit fee adds up quickly, and the operational complexity of splits is manageable.

Amazon AWD as a Third Option

Amazon Warehousing and Distribution (AWD) sits outside the IPS vs. distributed debate entirely. With AWD, you ship inventory to Amazon-managed upstream warehouses. Amazon then distributes stock into its fulfillment network on your behalf, on its own schedule. The key advantage: inbound placement fees do not apply to AWD shipments.

AWD charges work differently from FBA placement fees:

• Storage costs roughly $0.48 per cubic foot per month (with a 10% discount available for qualifying sellers, bringing it to $0.43).
• Inbound processing runs approximately $1.35 per box rather than per unit. For dense shipments with many units per box, this creates substantial savings over per-unit placement fees.
• There are no placement fees because Amazon controls the entire distribution chain from AWD warehouse to FC.

AWD tends to break even or save money compared to IPS when shipment volumes exceed 3,000 units or 5 pallets. For a seller sending 5,000 units of a large standard product, the IPS fee alone could run $3,000 to $5,000. AWD storage for the same volume (assuming 60 cubic feet) runs about $29 per month while the inventory sits in the AWD warehouse before distribution.

The trade-off is control. With AWD, you do not choose when Amazon moves your inventory into FCs. During peak season, distribution from AWD to FCs can slow down, leaving you with stock in the upstream warehouse that is not yet available for sale. Sellers who need precise control over when inventory becomes live on Amazon may find this unpredictable.

For sellers already managing a multi-warehouse fulfillment strategy, AWD adds another node to the network that needs monitoring. The cost savings are real, but so is the added complexity of tracking inventory across yet another system.

How to Choose: A Decision Framework

The right placement option depends on four variables: product weight, shipment volume, freight cost per destination, and your tolerance for operational complexity. Here is a simplified framework.

Choose distributed placement (optimized splits) if your products are small and light (under 2 lb), your shipment volumes are moderate (under 2,000 units), your freight costs to multiple locations are low, and you or your prep center can handle multi-destination shipments without significant added cost.

Choose IPS (single location) if your products are heavy or bulky (over 3 lb), you ship in high volume (over 3,000 units per restock), your prep center charges per shipment rather than per unit, or you need all inventory live as fast as possible with a single receiving window.

Choose AWD if you regularly ship 5 or more pallets per restock, you want to avoid placement fees entirely, you can tolerate Amazon controlling the distribution timeline, and your products are not seasonal with tight launch windows.

The FBA vs FBM inventory planning question also factors into this decision. Sellers who fulfill some orders themselves (FBM) have more flexibility because they are not routing 100% of their volume through Amazon's placement system.

For sellers running inventory across Amazon and other channels, the placement decision affects more than just Amazon fees. Inventory sitting in an Amazon FC or AWD warehouse is inventory that is not available for other channels unless you use Multi-Channel Fulfillment. That allocation decision should be part of your placement strategy, not an afterthought.

Track your actual costs for two or three restocking cycles under each option before committing to a permanent strategy. The fee structures change frequently, freight rates fluctuate, and your product mix may shift. A quarterly review of placement costs versus delivery performance keeps you from overpaying out of habit.
