How to Choose Inventory Management Software for Shopify and WooCommerce

• Native Shopify or WooCommerce stock control can be enough for small stores with few SKUs, one or two locations and simple purchasing.
• If the same SKU sells through Shopify, WooCommerce, Amazon or marketplaces, use one inventory source of truth instead of separate channel counts.
• Cin7 is the strongest ops tool in our index at $349/mo, ahead of Inventory Planner at $119/mo, Linnworks at $200/mo, Katana at $299/mo and Brightpearl at $1000/mo.
• Inventory Planner suits forecasting and replenishment, Katana suits manufacturing, Linnworks suits marketplace volume, and Brightpearl suits heavier retail operations.
• Price the full system before signing: users, orders, SKUs, integrations, locations, API access, onboarding, support and add-ons can change the real annual cost.

Inventory problems usually show up as a simple question: why did Shopify say an item was available when the warehouse had none left? The cause is rarely one bad setting. It is usually a stack of Shopify, WooCommerce, Amazon, spreadsheets, purchase orders and warehouse tools all holding different versions of stock.

Inventory management software for Shopify and WooCommerce should fix that mismatch. The right system receives orders, updates available stock, supports purchasing, and sends cleaner numbers back to every sales channel. The wrong one adds another place for staff to check before they can ship an order.

This guide is a decision framework, rather than a ranked list. Start with whether native Shopify or WooCommerce is still enough, then match the software type to the bottleneck: forecasting, manufacturing, marketplace volume, warehouse workflows or full retail ERP. The tool that fits a 50-SKU Shopify store will be wrong for a brand selling the same catalogue across Shopify, WooCommerce, Amazon and wholesale.

Do you need inventory software, or is native Shopify or WooCommerce enough?

Native stock control is enough if your store is simple. For a small Shopify store with few SKUs, one or two locations and basic replenishment, Shopify’s own inventory features may cover the job without adding a $299 or $349 monthly system.

The limitation is that native inventory starts to strain when purchasing, transfers, suppliers, bundles, forecasting or multiple sales channels matter. Shopify merchants also need to plan for Stocky: Shopify says Stocky was delisted from the Shopify App Store on 2 February 2026 and cannot be reinstalled, and it will no longer be available after 31 August 2026.

WooCommerce can also handle basic stock work. Its settings can track stock quantity, hold unpaid stock for a configured time, and adjust stock as sales and returns occur. That is useful for a WooCommerce-only store, but it does not make WooCommerce a forecasting system, warehouse system or ERP.

If your current problem is only low-stock visibility, a WooCommerce plugin or Shopify app may be enough. If the same SKU is sold across more than one storefront or marketplace, a channel-specific fix becomes risky. Each channel can look correct on its own while the shared stock pool is wrong.

Use the source-of-truth test before comparing vendors

The key test is whether one SKU is sold in more than one place. If the same product appears on Shopify, WooCommerce, Amazon, eBay or wholesale portals, one system should own the available stock number.

That system needs to receive orders from each channel, reserve or deduct stock, and push updated availability back to the storefronts. The upside is fewer oversells and fewer manual corrections. The catch is that setup becomes more serious, because product codes, variants, bundles and locations must be cleaned up first.

This is where inventory and order-management platforms become more relevant than lightweight plugins. Cin7, Linnworks, Katana and Brightpearl are built around broader operations, while Inventory Planner is better treated as a planning layer for demand forecasting and purchasing decisions.

Do not judge this only by whether the vendor has a Shopify or WooCommerce integration. Ask which system becomes the master record for products, stock, costs and purchase orders. That answer affects every workflow after launch.

Which type of tool matches your bottleneck?

Choose by the operational bottleneck, not by the longest feature list. Inventory software can mean stock tracking, forecasting, purchasing, warehouse management, manufacturing, order routing or retail ERP. Buying the broadest system before you need it creates admin you may not have the team to run.

If the problem is forecasting and replenishment, look at Inventory Planner. Its Shopify App Store listing describes forecasting, multi-location inventory, SKU management, stock replenishment, purchase orders, alerts and analytics. The limitation is scope: it should not be treated as a full ERP or WMS replacement.

If the problem is broad inventory control across channels, Cin7 is the stronger starting point in our ops index. It is recorded at $349/mo on Ecommerce Software and sits ahead of the other ops tools we track. The trade-off is that its plan limits and add-ons need close review before buying.

If the problem is manufacturing or assembly, Katana is the more natural fit. It is built around production planning, materials, purchasing and inventory, with a Core plan starting at $299/month. The catch is that paid add-ons can change the cost quickly.

If the problem is marketplace volume, Linnworks is the better fit to evaluate. It suits multichannel order routing, listings, inventory, shipping and warehouse workflows. It is less compelling if you only need a cleaner stock count for one Shopify store.

If the business needs a retail operating system, Brightpearl is the heavier option. It bundles inventory and order management, planning, fulfilment, shipping, WMS, accounting, reporting, CRM, integrations, implementation and support. That breadth is useful for mature operators, but it is not a quick plugin fix.

How do Cin7, Inventory Planner, Linnworks, Katana and Brightpearl compare?

Among the ops tools in our index, Cin7 ranks highest with an Index Score of 82 and a recorded price of $349/mo. Cin7 Core Standard is listed at $349/month and includes 5 users, 2 ecommerce or app integrations, 6,000 sales orders per year and unlimited inventory locations. That is a strong package, but the 2-integration and order limits matter for multichannel sellers.

Cin7 says it integrates with 700+ platforms, including Shopify, Amazon, WooCommerce, QuickBooks, Xero and Faire. That coverage makes it a sensible shortlist pick if you need inventory, purchasing, accounting connections and multi-location operations. The limitation is cost control: Cin7 lists separate fees or add-ons for API access, Flex API, premium support, professional services, advanced automations, extra users and extra connections.

Inventory Planner ranks next among these ops tools in our index, with a score of 79 and a recorded price of $119/mo. Its official pricing page says pricing is based on the volume of inventory managed and asks buyers to request pricing. That makes it important to compare the quoted annual cost against the forecast value it can create.

Inventory Planner’s strongest use case is planning rather than running the whole operation. It can help with demand forecasting, replenishment, purchase orders, alerts and analytics. The downside is that you still need another system to execute warehouse operations, manufacturing or full ERP workflows.

Linnworks has an Index Score of 78 and a recorded price of $200/mo. Linnworks says pricing is based on order volume rather than revenue, and that it does not charge percentage fees. That is useful for sellers with high average order values, but order-volume overages can apply if you exceed the monthly allowance.

Linnworks also sells add-on modules such as Linnworks Listing, Linnworks WMS and SkuVault Enhanced Warehouse based on order count, while Linnworks Forecasting is a flat-fee add-on. Onboarding is a one-off fee based on package, implementation timing and internal resources. The headline price is only part of the maths.

Katana also has an Index Score of 78, with our recorded price at $299/mo. Katana’s current pricing lists a Free Plan, a Core Plan starting at $299/month and an Advantage Plan with custom pricing. The Free Plan includes 30 SKUs, which is helpful for testing, but most serious sellers will outgrow that limit.

Katana’s Core Plan includes unlimited SKUs, users and integrations, with 1 inventory location included and 24/7 support. The issue is add-ons: Manufacturing Management is listed at $199/month, Traceability at $249/month, Warehouse Management at $149/month, and onboarding at $2,000. A manufacturing business should price the full build, not the base plan alone.

Brightpearl has an Index Score of 77 and our recorded price is $1000/mo. Brightpearl says pricing is tailored and that unlimited users are included at no extra cost. That can help larger teams, but the platform is aimed at a broader retail operating model rather than a narrow stock-sync problem.

Brightpearl says customers go live in 90–120 days on average and cites a 97% implementation success rate. That is a sign of a structured deployment, not a same-day install. If you need accounting, WMS, reporting, CRM, fulfilment and support in one retail system, it belongs on the shortlist.

How much does inventory management software cost?

Use our recorded prices as a starting point, then ask for a scoped quote. In our data, Cin7 starts at $349/mo, Inventory Planner at $119/mo, Linnworks at $200/mo, Katana at $299/mo and Brightpearl at $1000/mo. Those figures are useful for comparison, but they do not always reflect your final contract.

Inventory software costs are separate from Shopify fees, WooCommerce hosting, payment-processing costs and marketplace fees. Mixing those numbers hides the real software bill. Price the inventory system on its own, then check how it affects staff time, stockouts and purchasing mistakes.

Ask what the vendor charges for SKUs, users, orders, integrations, locations, warehouses, support, API access and onboarding. A tool can look cheaper until the second warehouse, extra marketplace or required implementation package is added.

For Cin7, check users, annual order limits, ecommerce or app integration limits, API fees, extra connections and support options. For Linnworks, check order-volume bands, overages, add-ons and onboarding. For Katana, check manufacturing, traceability, WMS, onboarding, locations and any volume-based costs.

For Inventory Planner and Brightpearl, ask for a written scope and compare annual totals. Inventory Planner’s pricing is volume-based and quote-led on its official page, while Brightpearl’s pricing is tailored. A vague demo estimate is not enough for budget approval.

What should Shopify stores check before switching?

Shopify stores should start with stock sync reliability, then move into operational fit. The tool must push stock back to Shopify in a way your team understands and can test. Vendor integration pages are useful, but real orders and real SKUs are the proof.

Check whether the system supports your locations, transfers, purchase orders, returns, bundles, suppliers and fulfilment workflows. A tool that handles simple stock counts may still fail on kits or multi-location transfers. That gap usually appears during busy periods, not during the demo.

If you rely on Stocky workflows, list them now. Purchase orders, stocktakes, transfers, supplier management and forecasting all need replacement plans before Stocky becomes unavailable after 31 August 2026. Waiting until the shutdown window creates avoidable migration pressure.

Also check the rest of the stack. Your inventory system may need to work with shipping software, a 3PL, accounting, marketplaces and marketing tools. Cin7’s broad integration coverage is useful here, but extra connections and implementation work may affect the final cost.

What should WooCommerce stores check before switching?

WooCommerce stores need to decide whether they need a plugin, a cloud inventory system or a full ERP. A small WooCommerce-only store may only need basic stock settings and a focused plugin. A multichannel seller needs a stronger source of truth.

Check how the system handles product sync, stock updates, orders, payments, shipping confirmations, returns and refunds. Brightpearl’s WooCommerce integration page covers those workflow areas, which suits its broader retail operations angle. The limitation is that Brightpearl is heavy for a small store that only needs stock decrements.

Decide whether WooCommerce remains the catalogue master. If the inventory system becomes the master product and stock record, staff need clear rules for where to edit SKUs, variants, costs and stock adjustments. Without that rule, duplicate fixes will creep back in.

Test sync behaviour before relying on it to prevent overselling. Use real SKUs, edge cases, refunds, partial shipments, bundles and out-of-stock items. A clean sandbox test is useful, but it is not a substitute for operational testing.

How should you plan the migration?

Clean up your SKU data before signing the contract. Duplicate SKUs, inconsistent variants, missing supplier codes, outdated costs and unclear location names will slow every implementation. Software cannot fix bad product data on its own.

Start with a pilot rather than a full cutover. Use one warehouse, one channel or a controlled group of SKUs. The upside is lower risk; the downside is that staff must run two processes for a short period.

Parallel-run old and new counts during the transition. Compare what Shopify, WooCommerce, the warehouse and the new inventory system think is available. Any mismatch should be investigated before the new system becomes the only operational record.

Assign ownership after launch. Someone must own purchasing, stock adjustments, failed syncs, supplier data, integrations and exception handling. Without named owners, the system will drift back into spreadsheet workarounds.

The practical recommendation framework

If you sell a small catalogue through one Shopify or WooCommerce store, start with native stock control and plugin-level fixes. That keeps cost and admin low. Move up only when shared SKUs, purchasing complexity or reporting gaps justify it.

If you need a Stocky replacement or broader SMB inventory system, shortlist Cin7 first among the ops tools we track. It has the strongest ops Index Score at 82 and a recorded price of $349/mo. Check plan limits and add-ons before treating it as the final answer.

If forecasting and replenishment are the weak points, shortlist Inventory Planner. If manufacturing, raw materials or production planning matter, shortlist Katana. If marketplace volume and order routing are the pressure points, shortlist Linnworks.

If the business has outgrown app-level operations and needs a wider retail operating system, shortlist Brightpearl. Its scope is broader, and its implementation window reflects that. It is better suited to mature retail teams than to stores wanting a quick stock-sync app.

The safest next step is to shortlist two tools based on the bottleneck, then test them with real SKUs, orders, returns and locations. A demo can show the interface. Your own data shows whether the system can run the business.

Frequently asked questions

What is the best inventory management software for Shopify and WooCommerce?

It depends on the bottleneck. Cin7 is the strongest ops tool in our index at $349/mo if you need broad inventory and ERP-style workflows. Inventory Planner fits forecasting and replenishment, Katana fits manufacturing, Linnworks fits high-volume multichannel operations, and Brightpearl fits heavier retail operations.

Can I use Shopify and WooCommerce without separate inventory software?

Yes, if the store is simple. Native Shopify inventory or WooCommerce stock settings can be enough for a small catalogue, one or two locations and basic stock control. You should look at dedicated software once the same SKU is sold across multiple channels, or when purchasing, forecasting, manufacturing or warehouse workflows become hard to manage.

How much should I budget for inventory software?

In our data, Cin7 is recorded at $349/mo, Inventory Planner at $119/mo, Linnworks at $200/mo, Katana at $299/mo and Brightpearl at $1000/mo. Treat those as starting points. Users, orders, SKUs, integrations, locations, API access, onboarding, support and add-ons can change the real annual cost.

Is Inventory Planner a full ERP?

No. Inventory Planner is best treated as a forecasting, purchasing and replenishment layer. Its listed features include forecasting, multi-location inventory, stock replenishment, purchase orders, alerts and analytics, but buyers needing warehouse operations, manufacturing or a full retail ERP should compare tools such as Cin7, Katana, Linnworks or Brightpearl.

What should Shopify merchants using Stocky do now?

List the Stocky workflows you rely on, then test replacements before the shutdown date. Shopify says Stocky was delisted from the App Store on 2 February 2026 and will no longer be available after 31 August 2026. Purchase orders, stocktakes, transfers, supplier management and forecasting all need replacement plans.

Should WooCommerce be the master inventory record?

Only if the store is simple and WooCommerce is the main operational system. For multichannel sellers, a dedicated inventory platform should usually become the source of truth for stock. Confirm how product sync, stock updates, orders, payments, shipping confirmations, returns and refunds work before changing that ownership.
