10 Best Inventory Software that Integrate with QuickBooks (2026)

Our main consideration when choosing the best inventory management integrations was to look for software features that would combine well with QuickBooks Online in terms of functionality and purpose. Since QuickBooks is used for accounting purposes like invoicing, tracking of expenses and income, and payment of bills, we looked for inventory management integrations that would make these things easier.

Automation was a big plus point for potential software providers, as automated processes remove the human error element, making accounting easier and more accurate.

We also looked for inventory management features that are useful in general: inventory counts, low-stock alerts, detailed reporting, and vendor management.

Zoho Inventory earns our top spot because it’s affordable, easy to use, and offers one of the most complete QuickBooks Online integrations available. Small businesses get access to strong core features, such as multilocation tracking, item bundling, barcode management, stock adjustments, purchase orders, and shipping tools, without the complexity or cost of a full ERP.

It’s especially useful for businesses selling across multiple channels. Zoho connects to Shopify, Amazon, Etsy, eBay, and multiple Shopify storefronts (depending on plan), making it a solid choice for retailers and ecommerce brands that need their inventory, orders, and fulfillment in sync.

While Zoho lacks advanced features like BOM management and advanced demand planning, its mix of price, usability, and functionality makes it the best all-around choice for most QuickBooks users.

Zoho offers a robust two-way sync with QuickBooks Online, making it one of the smoothest integrations on this list. You can:

• Sync items, invoices, bills, payments, and inventory adjustments
• Share vendor and customer records across both systems
• Update stock levels automatically as orders are created or fulfilled
• Map taxes, accounts, and currencies between platforms
• Import your QuickBooks contacts and export Zoho invoices and credit notes

Zoho often becomes the operational system of record for inventory, while QuickBooks remains your accounting source of truth — reducing manual data entry and improving accuracy.

• Multilocation & multi-warehouse tracking: Move stock between warehouses and monitor levels in real time.
• Bundling and kitting: Create product bundles and composite items easily.
• Shipping and fulfillment tools: Print labels, pack, and ship with integrated carriers.
• Multichannel ecommerce integrations: Connect to Shopify, Amazon, Etsy, eBay, and more.
• Expiration and batch tracking (higher tiers): Helpful for perishables and regulated goods.
• Multicurrency handling: Create transactions and manage payments with more than one currency, get automatic exchange rate updating, and view reports that summarize all transactions by contact.

Zoho offers monthly or annual billing. Monthly pricing:

Katana is purpose-built for manufacturers, makers, and product businesses that need to manage raw materials, work-in-progress, and production scheduling — not just finished goods. It gives you real-time visibility into what you can make, when you can make it, and which materials you need to purchase next.

Its visual production calendar, automated resource allocation, and bill of materials (BOM) tools make it easy to maintain optimal stock levels and avoid shortages. You can also track batch numbers or serial numbers, manage multiple warehouses, and run shop-floor operations from a single dashboard.

Katana is more expensive than general inventory software, but for manufacturers, the efficiency gains usually justify the cost.

Katana’s integration with QuickBooks Online eliminates a major pain point for manufacturers, manually transferring production and purchasing data into accounting. With the integration, you can:

• Sync finished goods and material balances between Katana and QBO
• Convert purchase orders into QBO bills with one click
• Sync customers, vendors, and sales orders
• Push costs and adjustments directly to your general ledger

Katana becomes your operational manufacturing and inventory system, while QuickBooks remains your financial system of record — keeping quantities, costs, and orders aligned without double entry.

• Production planning and scheduling: Real-time visibility into capacity, material availability, and work-in-progress.
• Bills of materials & costing: Track components, labor, and overhead to maintain accurate product costs.
• Shop-floor control: Assign tasks, track time, and monitor progress directly from the floor.
• Purchase order automation: Create and manage supplier orders with expected dates, locations, and currencies.
• Batch and serial tracking: Required for many regulated or perishable goods.
• Custom workflows via Katana API: Use the software’s API to create make-to-order workflows and other automations that simplify and streamline your operations.

All Katana plans include unlimited users

Odoo is a powerful open-source ERP platform that includes a free inventory module, making it appealing to businesses seeking flexibility and full control over their system. Unlike most plug-and-play inventory tools, Odoo lets you customize workflows, automate stock rules, and extend functionality with hundreds of apps, from CRM to manufacturing.

Its inventory module includes automatic replenishment, barcode support, batch and expiration tracking, and a double-entry inventory system that provides strong traceability. However, because Odoo isn’t a QuickBooks-native product, setup and maintenance require more technical expertise than most small businesses have in-house.

For tech-savvy users who need deep customization or for businesses already using Odoo for other operations, it can be a cost-effective and highly capable inventory solution.

Odoo and QuickBooks Online connect through third-party connector apps, not a native integration. While this adds cost, the sync can still be useful for businesses that want to keep accounting in QuickBooks but run operations in Odoo. Depending on the connector, you can:

• Sync customers, vendors, products, invoices, and bills
• Push purchase orders and receipts into QuickBooks
• Sync inventory values and adjustments
• Map taxes and accounts for clean financial reporting

Because Odoo handles operational workflows and QuickBooks manages financials, the combination works well, as long as you’re comfortable configuring the connector or hiring support. These third-party apps can cost upwards of $200. Here is one example: Odoo QuickBooks Online Connector PRO by VentorTech.

• Double-entry inventory system: Tracks every stock movement for high accuracy.
• Automated replenishment: Auto-generate RFQs or purchase orders when stock hits reorder levels.
• Expiration and lot tracking: Useful for perishables, cosmetics, pharma, and regulated items.
• Open-source customization: Modify workflows, fields, and automations to match your business.

Odoo offers a modular pricing model. Inventory is included in the free single-app plan.

• Free: One app (Inventory qualifies)
• Standard: ~$9.10/user/mo
• Custom: ~$13.60/user/mo

Third-party QuickBooks connectors cost extra, often $150–$400/year.

Square integrates with QuickBooks Online through the Square Connector app, which automatically imports your Square sales, payments, fees, and taxes into QuickBooks. This setup helps you:

• Keep accounting updated daily without manual entry
• Maintain accurate COGS and sales reporting
• Sync item and transaction details cleanly into QuickBooks

Inventory itself remains managed in Square, while QuickBooks handles the financial side, giving small businesses an efficient, low-maintenance workflow.

Lightspeed Retail is one of the most robust POS and inventory systems available for brick-and-mortar retailers. It stands out for its deep product organization tools, vendor catalogs, purchase ordering, serialized inventory, customizable categories, and strong reporting.

Retailers with large catalogs, multiple locations, or complex workflows (such as specialty sports stores, apparel boutiques, bike shops, and electronics retailers) will benefit from Lightspeed’s granular controls. It also supports built-in vendor ordering and access to thousands of supplier catalogs, making replenishment fast and accurate.

While its pricing is higher than simpler systems like Square or Zoho, Lightspeed offers the level of inventory detail that scaling retailers need, especially those managing high SKU counts or multiple stores.

Lightspeed connects to QuickBooks Online using a two-way sync via Lightspeed Accounting or a certified integration app. This allows you to:

Shopify is mainly known as a best-in-class ecommerce platform and lets you sell both online and in-store. Its inventory system tracks products across multiple locations, sales channels, and fulfillment methods, letting retailers manage everything in one place. Whether you’re selling on your website, through social channels, or in a physical store, Shopify keeps stock counts aligned automatically.

Shopify POS Pro adds deeper retail features such as staff roles, in-store pickup workflows, and advanced inventory tools. You can also use the Stocky app (included with POS Pro) for purchase orders, demand forecasting, vendor management, and detailed inventory analytics.

While Shopify isn’t the best fit for retailers who sell only in-store, it’s unmatched for omnichannel businesses that want integrated ecommerce, POS, and inventory in a single system.

That said, many of Shopify’s strongest inventory management features require you to subscribe to higher plans. The process for unlocking full functionality can also get complicated: you’ll need to subscribe to a Shopify ecommerce plan and upgrade to POS Pro.

Shopify connects to QuickBooks Online through a one-way sync, sending ecommerce and POS sales, refunds, fees, and taxes into your accounting automatically. This integration helps businesses:

• Keep online and in-store sales accurately recorded in QuickBooks
• Sync orders and payouts for clean financial reporting
• Map products, customers, and accounts without manual entry

Inventory management stays within Shopify as the source of truth, while QuickBooks handles the financial side, ideal for omnichannel operations.

• Omnichannel inventory syncing: Manage stock across your website, POS, marketplaces, and social channels.
• Multilocation inventory: Supports up to 10 locations on standard plans (more on Shopify Plus).
• Stocky app for POS Pro: Advanced purchase orders, forecasting, vendor tools, and inventory analytics.
• Flexible fulfillment: In-store pickup, curbside, local delivery, and ship-from-store workflows.

You’ll need to subscribe to a Shopify plan in order to use Shopify’s POS system and inventory functions. Here is the pricing for Shopify’s ecommerce plans:

• Basic
• • Monthly: $25 per month
  • Annual: $19 per month
  • 10 inventory locations
• Grow
• • Monthly: $65 per month
  • Annual: $49 per month
  • 10 inventory locations

  • One- or three-year term
  • 200 inventory locations
  • Unlimited staff accounts

Once you’ve subscribed, you can upgrade the POS from Lite to Pro for an additional monthly fee. If you then use the Stocky app with POS Pro, you’ll be at the highest level in terms of inventory management options.

• • Monthly: $89 per month, per location
  • Annual: $79 per month, per location (billed yearly)

MarketMan is a restaurant-focused inventory and vendor management system built for kitchens that need tight control over food costs, ingredient usage, and supplier ordering. It updates inventory in real time as recipes are prepared, items are sold, or invoices are scanned — giving restaurants an accurate picture of their COGS each day.

The platform also includes recipe costing, prep lists, waste logging, menu profitability analysis, and automated purchasing workflows. Restaurants can upload invoices by photo or PDF, and MarketMan will read line items, update ingredient counts, and prepare the invoice for QuickBooks — all without manual data entry.

MarketMan is pricier than general inventory tools, but it’s one of the few systems that truly handles restaurant workflows end-to-end.

MarketMan integrates with QuickBooks Online through a one-way sync, sending invoices, vendor details, ingredient-level purchases, and cost updates directly into your accounting. This helps restaurants:

• Automate AP entry from scanned invoices
• Maintain accurate daily COGS and food cost percentages
• Keep real-time ingredient usage aligned with financial reporting
• Reduce manual bookkeeping and entry errors

MarketMan handles operational inventory, while QuickBooks remains the financial source of truth, ideal for foodservice businesses with fast-moving stock.

• Recipe and menu costing: See profitability by dish and track cost fluctuations over time.
• Automated vendor management: Auto-generate POs, log deliveries, and track pricing changes.
• Invoice scanning: Upload invoices by photo and MarketMan updates stock automatically.

MarketMan inventory management software comes in three available plans. You can request a demo via the MarketMan website, but no long-term free plan is available.

Cin7 Core (formerly DEAR Systems) is one of the most powerful inventory add-ons for QuickBooks Online, ideal for wholesalers, ecommerce brands, and product-based businesses that have outgrown QuickBooks’ built-in inventory. It centralizes purchasing, sales, warehouse management, and production while integrating seamlessly with top marketplaces and ecommerce platforms.

Businesses that manage multiple warehouses, sell on several channels, or need accurate landed costing and backordering will find Cin7 Core especially valuable. It also includes light manufacturing features, such as assemblies, work orders, and bill of materials (BOM) support, making it a strong choice for small producers who want more structure than Zoho but don’t need the full complexity of Katana.

While it’s one of the more expensive tools on this list, Cin7 Core is also one of the most capable and a popular upgrade for brands scaling from QuickBooks Commerce or Shopify alone.

• Sync customers, suppliers, products, and stock levels
• Push sales, purchases, and manufacturing costs into QuickBooks

• Warehouse management: Bins, barcode scanning, and multi-location support.

Cin7 Core offers several plans depending on order volume and feature needs:

SOS Inventory is one of the most popular inventory add-ons for QuickBooks Online because it fills almost every gap in QuickBooks’ native inventory features, at a price small businesses can afford. It adds true multi-location tracking, manufacturing/assembly workflows, serial and lot control, reorder automation, and stronger purchasing tools.

It’s especially useful for wholesalers, distributors, and small manufacturers that have outgrown QuickBooks Online but don’t want the cost or complexity of a full ERP. SOS Inventory becomes the operational hub for inventory, while QuickBooks handles accounting, giving businesses accurate stock and financial data without double entry.

inFlow is a great fit for small product-based businesses that want an easy, intuitive inventory system without the complexity of an ERP. It’s especially popular among wholesalers, distributors, and B2B sellers because of its built-in B2B Showroom, barcode tools, simple purchasing workflows, and mobile capabilities.

With inFlow, you can track stock across multiple locations, scan products using a mobile device or inFlow’s dedicated Smart Scanner, manage purchasing and sales orders, and create custom catalogs for customers. The interface is very approachable, making inFlow ideal for teams looking for straightforward inventory control rather than deep manufacturing, forecasting, or automation.

While not as advanced as Cin7 Core or Katana, inFlow offers one of the best user experiences for small businesses that need organized, reliable inventory tracking.

QuickBooks Online includes reliable basic inventory tools, but it isn’t designed to handle more advanced or multilocation needs. Before choosing an add-on, it’s helpful to understand exactly where QuickBooks’ built-in features stop. The table below shows what QuickBooks Online can and can’t do, so you can quickly determine whether it’s enough for your business.

Use QuickBooks alone if you:

• Operate from one location
• Manage a small catalog (under ~100 SKUs)
• Don’t build products or assemble kits
• Sell through one sales channel

Upgrade with an inventory integration if you:

• Manage multiple stores or warehouses
• Need barcode scanning, detailed warehouse workflows, or bin locations
• Sell across multiple channels (POS + ecommerce + marketplaces)
• Need manufacturing, kitting, or recipe/ingredient tracking
