ChatGPTMost Amazon sellers manage inventory in spreadsheets until their first $50K stockout. Then they start shopping for tools. Reviewed September 2026, with Q4 restock decisions in front of most sellers, the stakes are higher: inbound placement fees, AWD allocation rules and FBA capacity limits all punish sellers who guess at restock timing. The problem with finding the right Amazon inventory management tool: dozens of platforms call themselves "inventory management," but they solve very different problems. Some focus on demand forecasting, others on profit per SKU, and a few just generate purchase orders.
This guide compares the 8 best Amazon inventory management tools in 2026. We've tested each tool's core capability, evaluated it against real seller needs (DOI tracking, restock alerts, multi-marketplace support, IPI optimization), and rated them by the problem they solve best. No tool does everything. The right choice depends on whether your biggest pain is stockouts, excess inventory, or lack of visibility.
Key Takeaway
Inventory management tools fall into three categories: demand forecasting tools (predict how much to order), profit analytics with inventory (show which products deserve FBA space), and operational/restock tools (automate purchase orders). Most sellers need one from the first or third category, plus a profit analytics layer to make informed decisions.
The calendar your restock plan is really working against
1.36% to 2.84%
FBA storage costs sellers 1.36% of sales in February and 2.84% in November on a fixed panel of several hundred Amazon sellers, measured over the twelve months to August 2026.

Amazon sellers on a fixed panel of several hundred Amazon sellers see four annual peaks, not one, across the two years to August 2026.

1.8x
The week before Black Friday already runs at roughly 1.8 times a normal trading day on a fixed panel of several hundred Amazon sellers, across both peak seasons measured.

Whichever tool you pick, it is forecasting into the same year. This is what storage cost and demand actually do across a fixed panel of several hundred Amazon sellers, so you can judge whether a tool's restock timing matches the real peaks.
What changed for Amazon inventory in 2026
Three shifts since late 2025 changed which features actually matter when choosing an inventory tool:
- Inbound placement fees stuck around. Sellers who opt for "minimal shipment splits" still absorb per-unit placement fees on most SKUs. Tools that only show on-hand quantity miss the real cost of bad restock decisions. You need landed-cost visibility before you commit a PO.
- AWD is pushed harder for slow movers. Amazon Warehousing & Distribution is positioned as the bulk storage layer that feeds FBA automatically, and low-velocity SKUs are steered there rather than into FBA directly. Forecasting tools that ignore AWD transfer lead times will under-restock fast movers and over-restock the rest.
- Capacity limits, not storage limits. Amazon feeds your Inventory Performance Index into a monthly FBA capacity limit, and a score under 500 is where restrictions start to bite. Tools that surface Days of Inventory per ASIN, not just per account, are now the difference between sending stock in freely and paying overage on every cubic foot above your cap.
The practical takeaway: a tool that just predicts demand is no longer enough. The shortlist below is weighted toward platforms that combine forecasting with profit-per-unit context, so you can answer "should I restock this SKU?" not just "when will I run out?". For the profit layer, see how Nova's FBA analytics Ties inventory health to contribution margin.
What to Look for in an Inventory Management Tool
Before comparing tools, here's the feature checklist that separates useful inventory tools from dashboard-only solutions:
Must-Have Features
- Days of Inventory (DOI) Tracking: per-ASIN, color-coded
- Restock alerts: Automated notifications when inventory is low
- Lead time management: Factor supplier + shipping + FBA check-in
- Multi-marketplace: If you sell in US + EU + UK
- Historical data: at least 90 days for trend analysis
Nice-to-Have Features
- Demand forecasting: AI/statistical prediction of future sales
- Purchase order generation: Auto-create POs from restock recommendations
- Profitability integration: see margin alongside inventory health
- Pipeline visibility: track inbound shipments and arrival dates
- IPI score tracking: Monitor the metrics that affect storage limits
The 8 Best Amazon Inventory Management Tools Compared
| Tool | Best For | Starting Price | DOI Tracking | Multi-Marketplace |
|---|---|---|---|---|
| Nova | Profit-led inventory decisions | $29/mo | Yes (color-coded) | Yes (20+ marketplaces) |
| SoStocked | Demand forecasting | $158/mo | Yes | Limited |
| RestockPro | FBA replenishment | $99/mo | Yes | US only |
| InventoryLab | Listing + accounting combo | $69/mo | Basic | US only |

1. Nova: Best for Profit-Led Inventory Decisions
Nova approaches inventory differently from forecasting-first tools. Instead of just predicting demand, it shows which products deserve FBA space based on profitability. The FBA Inventory module Displays DOI with color-coded thresholds (red/amber/green), demand velocity, stock position (available, reserved, inbound), and pipeline projections for every ASIN.
The core differentiator: Nova connects inventory health to P&L analytics. You don't just see that a product has 90 days of stock. You see that it's occupying 15% of your FBA capacity while contributing 3% of profit. That changes your restocking decisions. Multi-marketplace support covers 20+ Amazon marketplaces with currency normalization.
Strengths
- Color-coded DOI per ASIN
- Profit + inventory in one view
- 20+ marketplace support
- Pipeline projections
- Demand velocity tracking
Limitations
- No purchase order generation
- No supplier management
- Focused on analytics, not ops
2. SoStocked: Best for Demand Forecasting
SoStocked (now part of Carbon6) is the most advanced demand forecasting tool for Amazon sellers. It uses statistical models to predict future demand based on historical sales, seasonality, and promotional activity. The tool generates recommended purchase order quantities and timing.
SoStocked is best for sellers with 50+ SKUs who need automated forecasting and purchase order workflows. It's less useful for sellers who need profit analytics alongside inventory data.
Strengths
- Advanced demand forecasting
- Purchase order automation
- Seasonal adjustment models
- Supplier lead time tracking
Limitations
- Expensive ($158+/mo)
- Complex setup
- Limited marketplace coverage
- No profit analytics
3. RestockPro: Best for FBA Replenishment Automation
RestockPro focuses specifically on the FBA replenishment workflow: when to restock, how much to send, and generating shipment plans. It's a solid operational tool that reduces the manual work of managing FBA shipments.
Best for US-only sellers who want to automate the restock decision-making process. Not ideal for multi-marketplace operations or sellers who need profitability context alongside inventory decisions.
Strengths
- Restock recommendations
- Shipment plan creation
- Supplier management
- Affordable ($99/mo)
Limitations
- US marketplace only
- No profit analytics
- Basic forecasting
- Dated interface
4. InventoryLab: Best for Listing + Accounting Combo
InventoryLab combines listing workflow (scanning, listing, labeling) with basic accounting (COGS tracking, P&L by shipment). It's popular with arbitrage and wholesale sellers who need to track profitability per purchase batch.
InventoryLab's inventory features are secondary to its listing and accounting capabilities. DOI tracking is basic, and there's no multi-marketplace support. Best for US-based arbitrage sellers, not private label brands.
Strengths
- Listing workflow (Scoutify)
- Batch-level accounting
- COGS tracking per shipment
- Popular with resellers
Limitations
- US marketplace only
- Basic inventory analytics
- Not suited for private label
- No demand forecasting
5. Forecastly: Best for Advanced Statistical Forecasting
Forecastly specializes in statistical demand forecasting with models that account for seasonality, trends, and promotions. It's lighter than SoStocked but still focused on the forecasting problem rather than general inventory visibility.
Strengths
- Statistical forecasting
- Seasonal adjustments
- Clean interface
Limitations
- Limited marketplace support
- No profitability layer
- Narrow feature set
6. Helium 10: Best All-in-One with Inventory Add-on
Helium 10's inventory module (Inventory Management) is part of their all-in-one suite. It provides basic restock recommendations, DOI estimates, and shipment planning. It's not as deep as dedicated inventory tools, but it's convenient if you already use Helium 10 for keyword research and listing optimization.
Strengths
- Part of comprehensive suite
- Multi-marketplace support
- Large community/training
Limitations
- Inventory is secondary feature
- Basic forecasting
- No profit-per-SKU visibility
7. Jungle Scout: Best for Research + Basic Inventory
Jungle Scout's Inventory Manager provides basic restock recommendations within their product research platform. It estimates when to reorder based on sales velocity and lead time. Like Helium 10, inventory is a secondary feature. It's adequate for sellers with under 50 SKUs who don't need advanced forecasting.
Strengths
- Affordable entry point ($49/mo)
- Integrated with research tools
- Simple interface
Limitations
- Very basic inventory features
- Limited marketplace support
- No DOI color-coding
8. Sellerboard: Best Budget Option with Inventory
Sellerboard offers basic inventory monitoring as part of its budget-friendly profit analytics platform. It shows stock levels and basic restock alerts. The inventory features are minimal compared to dedicated tools, but at $19/month, it's the cheapest option that combines profit tracking with any inventory visibility.
Strengths
- Cheapest option ($19/mo)
- Multi-marketplace
- Profit + inventory combo
Limitations
- Very basic inventory alerts
- No forecasting
- Limited DOI granularity
Which Tool Should You Choose?
The right tool depends on your primary inventory pain point. Here's a decision framework:
"I need to know which products deserve FBA space based on profitability"
Choose Nova. It connects inventory health (DOI, velocity, pipeline) with P&L analytics so you can make profit-informed stocking decisions. Best for sellers scaling past $100K/month who need strategic inventory visibility across multiple marketplaces.
"I need accurate demand forecasting and automated purchase orders"
Choose SoStocked or Forecastly. Both specialize in statistical forecasting. SoStocked is more feature-rich (and expensive). Forecastly is lighter and cleaner.
"I just need restock alerts and shipment planning"
Choose RestockPro. It does one thing well: telling you when to restock and helping you create FBA shipments. US-only.
"I'm on a tight budget and need basic inventory + profit"
Choose Sellerboard at $19/month. Inventory features are minimal, but it's the cheapest combo of profit tracking and stock-level visibility.
"I want inventory as part of a bigger research/listing toolkit"
Stick with Helium 10 or Jungle Scout If you already use them. Their inventory modules are basic but adequate for small catalogs (under 50 SKUs).
Pro Tip: The Two-Tool Stack
Many successful sellers use two tools: a forecasting/operational tool (SoStocked or RestockPro) for purchase orders and restock timing, plus Nova for profit analytics and strategic inventory decisions. The forecasting tool tells you when to order. Nova tells you whether you should Order based on contribution margin and portfolio optimization.
