I Tested these Amazon Inventory Management Software: My Top 10 Picks

RestockPro is the tool I recommend first to any FBA seller managing 50+ active SKUs because it was designed specifically for the FBA reorder workflow — not adapted from generic inventory software. It captures your FBA data from Seller Central and converts it into per-SKU intelligence: expected margins, competitive listings, sales velocity, lead time from your specific suppliers, and recommended reorder quantity that accounts for your actual FBA receiving times, not theoretical estimates. Most competing tools show you what you have. RestockPro tells you what you need to do next — and when.

• Hundreds of data points analysed per SKU for restock recommendations
• Automated purchase order creation sent directly to suppliers
• FBA inbound shipment planning with Amazon box content rules (Send to Amazon workflow supported)
• Kitting support — manage bundles, multipacks, and multi-unit packs as unique SKUs with Kit Optimizer technology
• Sales velocity tracking with seasonal adjustment capability
• IPI monitoring and aged inventory alerts before storage fees hit
• Supplier management with lead time and cost tracking per vendor
• Available on 10 marketplaces: US, UK, Canada, Germany, France, Italy, Spain, Mexico, Netherlands, Australia

Amazon FBA sellers managing 50–2,000 active SKUs who need precise restock timing and automated purchase order workflows. RestockPro is not the right tool for FBM-only sellers or multi-channel operations — it is built exclusively for the FBA supply chain and does not manage eBay, Shopify, or other channel inventory.

SellerCloud earns its place because nothing in the mid-market price range matches its breadth of channel coverage and automation depth for high-SKU operations. It centralises product data, real-time inventory, and order management across Amazon, Walmart, eBay, Shopify, Target, and more — with automated workflows that reduce the operational staff required to run a large catalogue. The platform's G2 rating of 4.2/5 from 60+ reviews reflects genuine user satisfaction from sellers who have the scale to justify it. The $1,349/month starting price is the accurate 2026 floor for serious evaluation.

• Real-time inventory sync across Amazon, Walmart, eBay, Shopify, Target, and 300+ integrations
• Automated order routing and fulfilment rule engine
• Multi-warehouse stock allocation with transfer management
• Repricing automation integrated with inventory levels
• Purchase order management with supplier portals
• Business intelligence reporting across all channels
• Skustack warehouse management and Clocklocked labour tracking as add-ons

E-commerce operations processing 3,000+ orders per month across 5+ channels who need a single platform to manage product data, stock, orders, and fulfilment without channel-specific tool switching. Not appropriate for sellers under $1M annual revenue — the minimum monthly cost and implementation investment only makes economic sense at meaningful scale. Understanding the full 1P vs 3P selling model is important context before choosing SellerCloud, as it handles both Vendor Central and Seller Central operations.

Linnworks sits between SellerCloud (too expensive and complex for most sellers) and Sellbrite (too basic for scaling operations) — making it the natural fit for sellers hitting the limits of their current tool and managing 500–5,000 SKUs across 3+ channels. Its order management automation is particularly strong: routing rules, multi-warehouse allocation, and carrier selection can be automated without custom development work. The platform also provides B2B e-commerce capability (quotes, custom pricing) that most inventory tools ignore.

• Multi-channel inventory sync: Amazon, eBay, Shopify, Walmart, and 100+ integrations
• Automated order routing with configurable fulfilment rules
• Multi-warehouse stock tracking with transfer and allocation management
• Purchase order management with supplier performance tracking
• Kitting and bundling for complex product configurations
• B2B e-commerce module with quote management and custom pricing
• Custom reporting and analytics dashboards

Multi-channel sellers managing 500–10,000 SKUs who want powerful automation without the implementation complexity and cost of SellerCloud. Good fit for sellers transitioning from Sellbrite or Veeqo as their catalogue grows. Also serves brands with B2B wholesale operations alongside DTC and marketplace selling. For sellers who are actively optimising their Amazon Buy Box performance, Linnworks integrates with repricing tools to coordinate pricing and stock level decisions.

Skubana (now operating under Extensiv Order Management after Extensiv's acquisition) earns its place for one specific capability: exception-based management for stockout and overstock risk. Rather than showing you a dashboard of all your inventory, Skubana surfaces only the SKUs that require immediate action — prioritised by risk level. For sellers managing 200+ active SKUs, this exception-based approach saves hours of manual data scanning that other tools require. The platform also handles 3PL integration natively, which matters for sellers using multiple warehouse partners.

• Exception management surfacing only at-risk SKUs requiring action
• Automated replenishment task generation based on demand signals
• Native 3PL integration with ShipBob, Deliverr, and major providers
• Cross-channel inventory allocation optimisation
• Orderbot automation for routing orders to the optimal fulfilment node
• Detailed unit economics and channel profitability analytics
• Connected analytics across Amazon, Shopify, Walmart, and other channels

Enterprise e-commerce brands with complex fulfilment networks spanning FBA, 3PLs, and owned warehouses who need unified inventory and order management. Also a strong choice for sellers running Amazon FBM (Fulfilled by Merchant) operations where warehouse allocation across multiple sites is the primary complexity. Best suited to sellers already at scale rather than growing operations.

Veeqo is the most underrated tool on this list specifically because its Shipping plan is free and most sellers assume free means limited. Amazon acquired Veeqo in 2021 and has invested significantly in its capabilities since then — it is now a legitimate multi-channel inventory and shipping management platform that competes with paid tools in most feature areas. The Shipping plan is entirely free (Veeqo earns revenue from shipping label commissions). For sellers who also need automated inventory sync across channels, the Inventory plan starts from $19/month — still exceptional value. Importantly, FBA and MCF orders are excluded from chargeable order volume, so unlimited FBA orders can be imported without increasing subscription costs.

• Shipping plan (free): multichannel shipping from Amazon, Shopify, eBay, Walmart, WooCommerce and more
• Inventory plan (from $19/mo): automated inventory sync across channels + demand forecasting
• High Volume plan (from $350/mo): adds dedicated account manager, API consulting, NetSuite ERP integration
• Shipping label creation with UPS, USPS, FedEx, DHL, Amazon Shipping — pre-negotiated lowest commercial rates
• Up to 5% back in Veeqo Credits on every label purchased
• Unlimited users, products/SKUs, and warehouses on all plans
• FBA and MCF orders excluded from chargeable order volume

New and growing Amazon sellers who want multi-channel shipping and inventory management at the lowest possible cost while scaling. Also a natural fit for sellers who ship high volumes domestically (Veeqo offers pre-negotiated carrier rates plus Veeqo Credits). For deeper FBA forecasting, Veeqo pairs well with RestockPro — free/low-cost multi-channel tracking plus FBA-specific reorder intelligence.

Zoho Inventory earns its place because it delivers the most complete operational stack at the lowest price point — particularly for sellers already using Zoho Books for accounting, where the native integration eliminates the double-entry problem that plagues most inventory-accounting combinations. The free plan handles up to 50 orders/month and is genuinely functional for very small operations. Paid tiers scale from $29/month (Standard, billed annually) up to $249/month (Enterprise, billed annually), with a 15% nonprofit discount available. The tradeoff is Amazon integration depth — Zoho connects via API but lacks the FBA-specific intelligence of RestockPro or the enterprise scalability of SellerCloud.

• Amazon integration for inventory updates and order sync
• Native connection to Zoho Books for accounting without manual export
• Multi-warehouse stock tracking and transfer management
• Purchase order management with supplier tracking
• Serial number and batch tracking for regulated products
• Barcode generation and scanning support
• Shopify, eBay, Etsy, Walmart integrations alongside Amazon
• 14-day free trial; perpetual free plan for small operations

Small to medium Amazon sellers (under 500 SKUs) who want a complete operational stack — inventory, orders, and accounting — without paying enterprise prices. Particularly strong for sellers already using Zoho products, where the ecosystem integration produces significant workflow efficiency. Also a good choice for sellers who sell on Amazon and their own Shopify store with roughly equal volumes.

Sellbrite (a GoDaddy brand) is the most approachable multi-channel inventory tool for sellers just expanding beyond Amazon to eBay, Etsy, or their own Shopify store. The setup is genuinely fast — most sellers connect all channels and have inventory syncing within a day. It offers a forever free plan for up to 30 orders/month, and paid plans scale from $29/month (Pro 100, billed annually) for up to 100 orders, to $79/month (Pro 500, 500 orders) and $179/month (Pro 2K, 2,000 orders). Amazon FBA orders are specifically excluded from the order count on paid plans, making it very cost-effective for FBA-heavy sellers. The interface is clean and the learning curve is the gentlest of any paid tool on this list.

• Forever free plan: up to 30 orders/month, unlimited SKUs, unlimited channels
• Multi-channel inventory sync: Amazon, eBay, Shopify, Etsy, Walmart, Google Shopping
• Centralised listing management — list to multiple channels from one place
• Multi-warehouse inventory visibility with selective stock push per channel
• Order management with USPS, UPS, FedEx shipping label creation
• Amazon FBA orders excluded from monthly order count on all paid plans
• Optional FBA Integration add-on ($19/mo) for FBA inventory import and MCF order routing
• 15-minute inventory and price sync frequency on all paid plans

New multi-channel sellers with 30–500 monthly orders expanding from Amazon to 2–4 additional channels who want a simple, fast setup without a steep learning curve or enterprise pricing. The free plan makes it ideal for testing multi-channel operations before committing to a subscription.

Ordoro earns its place for one specific seller type: high-volume FBM sellers who ship 500+ packages per month domestically and want to reduce per-shipment cost through carrier rate optimisation alongside inventory management. Its shipping rules engine is the most configurable on this list — automatically selecting the cheapest carrier and service level for each order based on weight, dimensions, destination, and delivery promise. The dropshipping automation (routing orders directly to suppliers) is also among the best available for Amazon FBM dropshippers.

• Carrier rate shopping across UPS, USPS, FedEx, DHL, and regional carriers
• Automated dropshipping order routing to suppliers
• Multi-channel inventory sync with Amazon, eBay, Shopify, and more
• Kitting and bundling management
• Shipping rules engine for automated carrier and service selection
• Supplier management and purchase order workflows

FBM sellers shipping 500+ monthly orders who want shipping cost reduction alongside inventory management, and Amazon sellers who dropship from suppliers directly to customers. For sellers exploring the Amazon dropshipping supplier landscape, Ordoro's automated routing features make fulfilment management significantly more efficient at scale.

InventoryLab at $69/month covers three functions that most sellers pay for separately: FBA inventory tracking, P&L accounting per SKU, and the Scoutify 2 mobile app for retail arbitrage sourcing decisions in-store. No other single platform covers all three at this price. For FBA private label sellers specifically, the per-SKU profitability view — factoring in all FBA fees, COGS, advertising spend, and storage charges — produces the clearest picture of which products are actually profitable versus which ones only look profitable at the revenue level. Understanding Amazon FBA private label economics makes InventoryLab's accounting integration especially valuable.

• FBA inventory tracking with inbound shipment management
• Per-SKU P&L accounting including all Amazon fees (referral, FBA, storage)
• Scoutify 2 mobile app for retail arbitrage sourcing decisions with instant profit calculations
• Cost of goods tracking per purchase and shipment
• Tax reporting features for end-of-year Amazon seller filings
• Supplier management and purchase order creation
• Detailed profitability reports across FBA catalogue

FBA private label sellers who need per-SKU profitability clarity, and retail arbitrage sellers who want sourcing + inventory + accounting in one tool at $69/month. Not suitable for multi-channel sellers needing eBay or Shopify inventory sync.

SoStocked (now part of SPS Commerce) earns the #10 position for two genuinely unique capabilities. First: the ProfitFlow tier ($97/mo) is the only forward-looking profit tool that forecasts sales, fees, and costs simultaneously — spotting underperforming ASINs and hidden fee drains before they appear in your monthly P&L. Second: the full ProfitFlow + Inventory tier ($250/mo) adds cash-flow-aware reorder recommendations — factoring your budget reality into which stockouts to prioritise when you cannot afford to restock everything at once. For capital-constrained sellers managing seasonal demand spikes, this prevents the false choice between over-stocking slow-movers and under-stocking fast-movers.

• ProfitFlow ($97/mo): profit planning dashboards, fee prevention insights, automated margin optimisation, profit leak detection
• ProfitFlow + Inventory ($250/mo): everything in ProfitFlow + inventory dashboards, advanced forecasting, reorder alerts, inventory tracking, PO creation
• Seasonal sales trend modelling with manual override capability
• Supplier and lead time management with variability tracking
• Overstock and aged inventory alerts with storage fee projections
• All Amazon marketplaces supported (US, UK, EU, Canada, and more)
• Full AWD (Amazon Warehouse & Distribution) integration
• Multi-Channel Fulfillment (MCF) support for Shopify-fulfilled-via-FBA sellers

FBA sellers managing seasonal products or multiple product lines who need demand forecasting that accounts for budget reality, not just demand signals. The ProfitFlow-only tier ($97/mo) suits any Amazon seller who wants automated profit strategy without full inventory management. Also strong for sellers running Amazon PPC campaigns — SoStocked connects fee data and sales forecasting to give a true picture of net margin per ASIN including advertising costs.
