Overselling is the fastest way to destroy customer trust. You list an item on Shopify and Amazon, it sells on both channels within minutes, and now you’re sending an apology email and issuing a refund to one customer. Spreadsheets work when you have 20 products on one channel. Once you’re selling across multiple platforms with hundreds of SKUs, you need dedicated inventory management: or you’ll spend your evenings playing catch-up with stock counts.

But here’s the thing: inventory management software is expensive compared to other e-commerce tools. Plans start at $59/month and quickly climb to $350+. So the real question isn’t “which one is best?”: it’s “do I actually need this yet, and if so, which one fits my stage?”

Cin7 Core: Best for Multi-Location + Wholesale

Pricing: $349+/month

Cin7 Core (formerly DEAR Inventory) is the heavyweight of small-to-mid-market inventory management. It handles multi-location warehousing, B2B wholesale with customer-specific pricing, purchase orders, manufacturing bills of materials, and integrations with virtually every platform and accounting tool you’d use.

If you sell both wholesale and direct-to-consumer, Cin7 handles both workflows in one system. Set up different price lists for customer groups, manage minimum order quantities, and automate reorder points across multiple warehouses.

The integration library is massive: over 700 connections including Shopify, Amazon, eBay, Xero, QuickBooks, and dozens of 3PLs. The downside: $349/month is a big commitment. Cin7 makes sense once you’re managing $30K+/month in inventory across multiple locations or channels.

Pros: Most complete feature set, excellent multi-location management, wholesale + DTC in one platform, deep integrations, strong reporting and forecasting.

Cons: Expensive ($349/month minimum), complex setup (budget 2–4 weeks), overkill for simple operations, learning curve is steep, support can be slow on lower tiers.

Ordoro: Best for Dropshipping + Multi-Channel

Pricing: $59–$149/month

Ordoro is built for e-commerce sellers who juggle multiple suppliers, dropshipping relationships, and selling channels. It combines inventory management with shipping label printing and supplier automation in one dashboard.

The standout feature is automated dropship routing. When an order comes in, Ordoro automatically routes it to the correct supplier based on your rules. You get tracking updates back from suppliers and pass them to customers without manual intervention.

Multi-channel inventory sync covers Shopify, Amazon, eBay, Etsy, BigCommerce, and WooCommerce. For stores that mix their own inventory with dropshipped products, Ordoro handles both workflows cleanly.

Pros: Best dropship automation, combines inventory + shipping, good multi-channel sync, reasonable pricing, handles mixed inventory/dropship models well.

Cons: No barcode scanning, no demand forecasting, reporting is basic, no manufacturing/BOM features, limited warehouse management (no bin locations).

inFlow: Best for Product-Based SMBs

Pricing: $89–$219/month

inFlow targets the product-based small business that’s outgrown spreadsheets but doesn’t need enterprise features. It’s a traditional inventory management system with a modern interface: purchase orders, stock adjustments, barcode scanning, multiple locations, and solid reporting.

The strength is simplicity relative to capability. Set up your product catalog with variants, track costs and margins, create purchase orders when stock runs low, and get reports on sell-through rates: all without the steep learning curve of Cin7.

Barcode scanning works through a mobile app on your phone. Walk through your warehouse, scan items, and do stock counts or pick orders. Integrations include Shopify, WooCommerce, Amazon, and major accounting platforms.

Pros: Clean interface, solid barcode scanning via mobile app, good for physical product businesses, reasonable pricing tier, purchase orders with supplier management, good margin reporting.

Cons: No dropship automation, no manufacturing features, multi-channel sync limited to major platforms, no demand forecasting on lower plans, mobile app could be more polished.

Katana: Best for Manufacturers + Made-to-Order

Pricing: $99–$399/month

Katana is purpose-built for brands that manufacture or assemble their own products. If you make candles, mix cosmetics, sew clothing, or assemble electronics: basically, if raw materials go in and finished products come out: Katana is your tool.

The manufacturing focus means features like bills of materials (BOMs), production planning, shop floor control, and material availability checking. When you get an order for 100 units, Katana shows whether you have enough raw materials, suggests a production schedule, and tracks work-in-progress.

Inventory tracking covers both raw materials and finished goods. Reorder points work on both levels: get alerted when Component A runs low, not just when Product X runs low. Integrations include Shopify, WooCommerce, QuickBooks, and Xero.

Pros: Only tool truly built for small manufacturers, excellent BOM and production planning, tracks raw materials + finished goods, good Shopify integration, visual production scheduling.

Cons: Not designed for pure retailers (no advantage if you don’t manufacture), pricing climbs quickly with users and features, limited marketplace integrations (no Amazon/Etsy), smaller company (less ecosystem around it).

Shopify Built-in Inventory: Fine for Single-Channel Under 100 SKUs

Pricing: Free with any Shopify plan

Shopify’s built-in inventory tracking is often overlooked. It handles the basics well: track stock levels per product and variant, get low-stock notifications, transfer stock between up to 10 locations, and view inventory history.

For stores selling exclusively through Shopify with fewer than 100 SKUs and no wholesale channel, the built-in system is genuinely sufficient. You don’t need a $59–$349/month tool just to track that you have 47 units of blue t-shirts in medium.

The limitations are clear: no purchase orders, no supplier management, no demand forecasting, no multi-channel sync beyond Shopify, and no manufacturing tracking. It’s simple inventory counting with location support: nothing more.

Pros: Free, no extra tool to manage, works immediately with your Shopify store, supports multiple locations (up to 10), integrates with Shopify POS for physical retail.

Cons: No purchase orders, no multi-channel sync, no demand forecasting, no barcode receiving, very basic reporting, doesn’t connect to Amazon/Etsy/eBay.

Do You Actually Need Dedicated Inventory Software?

Not every store needs a $100+/month inventory tool. Here’s my honest take on when you do and don’t need one:

You DON’T need dedicated inventory software if:

• You sell on one channel only
• You have fewer than 100 SKUs
• You don’t sell the same items on multiple platforms
• Your turnover is slow enough that manual stock checks catch issues

You DO need dedicated inventory software if:

• You sell on 2+ channels (Shopify + Amazon, for example)
• You’ve oversold items more than twice in the past month
• You manage 200+ SKUs with variants
• You have wholesale AND direct-to-consumer sales
• You manufacture products and need raw material tracking

The cost of overselling (refunds, apology discounts, damaged reviews) usually exceeds the cost of inventory software once you’re doing $10K+/month across multiple channels.

FAQ

Can I use inventory software with Shopify’s built-in tracking? Yes. Most dedicated tools override Shopify’s inventory counts with their own synced data. You’ll manage inventory in the dedicated tool, and it pushes updated stock levels to Shopify automatically. Disable Shopify’s stock tracking for products managed externally to avoid conflicts.

How long does setup take for these tools? Simple setups (inFlow, Ordoro with under 200 SKUs): 1–3 days. Complex setups (Cin7 with multiple warehouses, 1000+ SKUs): 2–4 weeks including data migration and staff training.

What’s the best free inventory management option? For Shopify sellers: Shopify’s built-in tracking. For multi-channel sellers: some use Google Sheets with inventory add-ons. But “free” usually means manual work: the time cost adds up past 50 orders/week.

Do these tools handle Amazon FBA inventory? Cin7 and Ordoro both sync with Amazon FBA, tracking units at Amazon’s warehouses alongside your own. inFlow and Katana have more limited Amazon integration.

What happens during peak seasons (Black Friday, holidays)? Good inventory software helps you prepare by forecasting demand (Cin7 and Katana do this best). During the rush, real-time sync prevents overselling. Set buffer stock levels and increase reorder points 4–6 weeks before peak season.
