Top 10 Amazon Inventory Management Tools in 2026

Amazon's built-in inventory management includes FBA inventory levels, restock recommendations, stranded inventory alerts, and the Inventory Performance Index. It's free and already there.

For sellers with a small catalog, under 20 SKUs. It's functional. The restock recommendations give you a rough idea of when to reorder. But the alerts are often too late, there's no automation, no cross-tool integration, and no way to customise thresholds. You're checking it manually and hoping you don't miss anything.

Best for: very small sellers who don't need anything beyond basic FBA visibility.

Forecastly focuses on demand forecasting, predicting when you'll run out of stock based on sales velocity and seasonal patterns. It identifies excess inventory too, helping you avoid long-term storage fees.

The forecasting goes beyond simple "stock is low" alerts, which is useful for planning. The limitation is that it only forecasts. It doesn't alert you in real time, doesn't create restock tasks, and doesn't connect to your other tools. You still have to act on the forecasts yourself.

Best for: sellers who want data-driven restock timing based on velocity forecasting.

InventoryLab combines inventory tracking with per-SKU profitability analysis. The Scoutify app is popular with arbitrage and wholesale sellers for scanning products and calculating profit on the spot. It also handles FBA shipment creation and accounting reports.

It's a good tool for sellers who source products in-store or from wholesalers and need to track profitability alongside inventory. The limitation: it's focused on accounting and sourcing, not on monitoring and alerts. It won't notify you when stock is running low or create tasks when you need to reorder.

Best for: arbitrage and wholesale sellers who need inventory tracking tied to profitability.

RestockPro is specifically designed for FBA restock planning. It calculates restock recommendations based on sales velocity and supplier lead times, manages purchase orders, and helps plan FBA shipments.

The lead time tracking is a genuine advantage. It factors in how long your supplier takes to deliver, so your restock alert fires early enough to avoid a gap. It's more sophisticated than Amazon's native recommendations. The limitation is that it's FBA-only and focused on planning, not real-time monitoring or automation.

Best for: FBA sellers who want detailed restock planning with supplier lead time tracking.

SoStocked is the most customisable inventory forecasting platform available. You can build custom forecasting models, adjust for seasonality, manage purchase orders, and handle multi-marketplace inventory. If you have complex forecasting needs, it offers more flexibility than anything else on this list.

The depth of customisation is impressive. But it comes with a learning curve and a higher starting price. It's a planning tool, not a monitoring or automation tool. It tells you when to reorder based on sophisticated models, but it doesn't create the restock tasks, alert your team, or update your spreadsheets.

Best for: sellers with complex catalogs who need highly customisable demand forecasting.

Sellerboard is primarily a profitability tool, but its inventory monitoring and automated FBA reimbursement claims earn it a spot on this list. It tracks stock levels alongside real per-SKU profit, so you can see both how much stock you have and whether it's worth restocking.

The reimbursement feature is quietly valuable, Amazon loses and damages more inventory than most sellers realise, and Sellerboard identifies and files claims automatically. At its price point, it's the best value combination of profit tracking and basic inventory monitoring available.

Best for: sellers who want profitability tracking and basic inventory alerts at the lowest price.

Zoho Inventory is a multi-channel inventory management tool that syncs stock across Amazon, Shopify, eBay, and other marketplaces. It handles warehouse management, order management, and shipping integration.

If you sell on three or more channels and need inventory to stay in sync everywhere, Zoho does the job well. It's part of the broader Zoho ecosystem, so it integrates with their CRM, accounting, and other business tools. The trade-off is that it's not Amazon-specific. No FBA intelligence, no Amazon-native features, and no AI.

Best for: multi-channel sellers who need inventory syncing across Amazon, Shopify, and eBay.

Helium 10 includes an inventory management module as part of its seller suite. It offers restock suggestions based on sales velocity, supplier management, and FBA shipment planning, all integrated with Helium 10's product research and keyword data.

The integration advantage is real: your inventory data sits alongside your keyword rankings, listing performance, and advertising metrics in one platform. For existing Helium 10 users, it's a natural addition without another subscription. The inventory features aren't as deep as dedicated tools like SoStocked or RestockPro, but for most sellers they're sufficient.

Best for: existing Helium 10 users who want inventory management alongside their research tools.

Jungle Scout's Inventory Manager offers demand forecasting tied to their product intelligence data. It calculates restock recommendations, tracks supplier lead times, and estimates FBA fees for planned shipments. The integration with Jungle Scout's market data adds context that standalone inventory tools don't have.

For Jungle Scout users, it's a useful addition, particularly during the launch phase when forecasting demand for a new product is hardest. Like Helium 10's inventory module, it's solid but not as deep as dedicated inventory tools. It won't automate your restock process or connect to your project management tools.

Best for: Jungle Scout users who want inventory planning tied to product intelligence data.

Every other tool on this list tells you there's an inventory problem. Jarvio does something about it.

The pattern with inventory tools is predictable: they give you a dashboard showing stock levels, maybe some forecasting, maybe an alert. Then it's on you to check the dashboard, interpret the data, create restock orders, notify your team, and update your tracking spreadsheet. The tool did its job. It showed you the number. Everything after that is manual.

Jarvio breaks that pattern entirely.

The Jarvio Agent

Ask the Agent "which products are below 50 units?" and it checks your FBA inventory in real time. Not a dashboard you go look at, but an answer to your question with the actual data. "Create restock tasks in ClickUp for each one and alert the team on Slack." Done, tasks created, team notified. "Run this every morning at 8am." Scheduled. Daily automated inventory monitoring without you thinking about it again.

You can ask more nuanced questions too: "What's my days-of-stock for my top 10 products?" "Which products have been declining in stock velocity this month?" "Show me anything that's going to stock out in the next 14 days based on current sell-through rate." The Agent understands inventory context because it was built by people who've lived the pain of stockouts.

The automation platform behind it

Behind the Agent is a full inventory automation engine. All FBA report types, inventory levels, inbound performance, reimbursements, non-compliance, restock recommendations. Connected to Google Sheets, Asana, Notion, ClickUp, Slack, Gmail, and anything with an API.

A typical inventory workflow: daily FBA inventory pull → filter products below your restock threshold → calculate days-of-stock remaining → create restock tasks with quantities in ClickUp → update your inventory tracking Google Sheet → send a Slack alert to your team with the summary → if anything is critical (under 3 days of stock), send an urgent email to the buyer.

That entire workflow runs every morning at 8am. No checking, no remembering, no manually creating tasks. When you arrive at your desk, the tasks are already created, the spreadsheet is already updated, and your team already knows what needs ordering.

Why it's different from every other inventory tool

SoStocked gives you a sophisticated forecast. RestockPro gives you a restock plan. Sellerboard gives you an alert. Jarvio gives you a forecast, creates the restock tasks, updates your tracking sheet, notifies your team, and does it again tomorrow, all without you opening a single dashboard.

For sellers who've experienced a preventable stockout, and the weeks of lost ranking that follow, this is the tool that makes sure it doesn't happen again.

Best for: any seller who wants inventory monitoring that takes action, not just shows data.
