9 Best Manufacturing Inventory Management Software [2026] 2026

Managing inventory in manufacturing is fundamentally different from retail or ecommerce. You are not just tracking finished goods on shelves — you are juggling raw materials, work-in-progress (WIP), sub-assemblies, and finished products across production lines that run on bills of materials, not shopping carts.

Generic inventory tools fall short here. A Shopify app that tracks T-shirt sizes will not help you manage a multi-level BOM with 47 components, calculate material requirements for next week’s production run, or trace a quality defect back to a specific batch of raw aluminium. You need software built for how manufacturing actually works.

This guide compares nine manufacturing inventory management tools worth evaluating in 2026 — from affordable cloud MRP systems starting at $49/user/month to full enterprise ERP suites. We cover what each does well, where it falls short, and which type of manufacturer it suits best.

Why Manufacturers Need Specialised Inventory Software

Before diving into specific tools, it is worth understanding what separates manufacturing inventory from standard warehouse or retail inventory:

Bill of Materials (BOM) management. Every finished product is made from components, and those components may themselves be assemblies. Your software needs to handle multi-level BOMs, calculate material requirements, and trigger purchase orders when raw material stock drops below reorder points. A reorder point calculator helps with the maths, but your core system needs to automate the process.

Work-in-progress tracking. Raw materials enter the factory, pass through multiple production stages, and emerge as finished goods. At any given moment, significant capital is tied up in WIP inventory. Your software needs to track where materials are in the production process and what they are worth — critical for accurate COGS calculations.

Production scheduling and capacity planning. Manufacturing inventory is not just about counting stock — it is about planning when to make what, ensuring materials arrive on time, and not overloading production capacity. This is where MRP (Material Requirements Planning) comes in.

Lot and serial number traceability. When a customer reports a defect, you need to trace the finished product back through every production stage to the specific batch of raw materials. This is non-negotiable in food, pharmaceuticals, electronics, and automotive manufacturing.

Multi-location coordination. Many manufacturers operate across warehouses, production facilities, and distribution centres. Inventory needs to be visible across all locations in real time to prevent stockouts on the production floor.

Key takeaway: If your current “inventory management” is a spreadsheet with columns for raw materials and finished goods, you are likely losing money through production delays, emergency purchases, and invisible WIP costs. Even a basic manufacturing MRP system pays for itself within months.

Quick Comparison: Manufacturing Inventory Software at a Glance

1. Katana MRP

Best for: Small to mid-size manufacturers who want cloud-native production planning without enterprise complexity.

Starting price: Free plan (30 SKUs) / $299/month (Core plan, unlimited SKUs)

Katana has become one of the most popular cloud manufacturing platforms since launching in 2017. Its core strength is real-time master planning — a live dashboard that shows material availability, production status, and order commitments in a single view. When a sales order comes in, Katana instantly recalculates what needs to be produced and what raw materials need to be purchased.

What it does well:

• Visual production scheduling with drag-and-drop prioritisation
• Auto-booking of materials — raw materials are reserved to manufacturing orders automatically
• Shopify and WooCommerce integration for manufacturers selling D2C
• Unlimited users on all plans (no per-seat charges)
• Real-time floor-level tracking with barcode scanning and tablet views

Where it falls short:

• The free plan caps at 30 SKUs, which is only useful for testing
• $299/month is steep for very small workshops
• Additional inventory locations and sales orders are billed separately, making costs less predictable
• Advanced reporting requires add-ons

Best fit: Manufacturers with 50–5,000 SKUs who need production planning integrated with ecommerce. Particularly strong for consumer goods manufacturers who sell via Shopify alongside wholesale.

2. MRPeasy

Best for: Budget-conscious manufacturers who need a full MRP system without enterprise pricing.

Starting price: $49/user/month (Starter) / $69/user/month (Professional)

MRPeasy is one of the most affordable full-featured manufacturing MRP systems available. Despite the low price, it covers the entire manufacturing workflow: production planning, BOM management, procurement, inventory, quality control, and basic accounting. It currently serves over 2,500 manufacturers globally.

What it does well:

• Complete MRP at a fraction of the cost — the $49/user/month Starter plan includes production planning, BOM management, and drag-and-drop rescheduling
• Lot traceability built into every tier
• 10+ integrations including QuickBooks, Xero, Shopify, and WooCommerce
• 15+15 day free trial with no credit card required
• Subcontracting management on Professional tier and above

Where it falls short:

• Per-user pricing adds up quickly for larger teams (10 users at $49 = $490/month)
• The Starter tier lacks serial number tracking and quality control features
• Interface is functional but less polished than Katana
• API access is only available on the Unlimited plan ($149/user/month)

Best fit: Manufacturers with small teams (1–10 users) who need proper MRP without paying enterprise prices. Particularly popular with machine shops, food producers, and contract manufacturers.

3. Fishbowl Manufacturing

Best for: Manufacturers already using QuickBooks who need production planning without switching accounting systems.

Starting price: $349/month (Fishbowl Drive, cloud) / Custom quote (Fishbowl Advanced, on-premise)

Fishbowl has been a manufacturing inventory staple for over 20 years, originally built as the inventory management layer that QuickBooks lacked. The integration between Fishbowl and QuickBooks remains its defining advantage — manufacturing orders, cost of goods, and inventory adjustments flow directly into QuickBooks without manual journal entries.

What it does well:

• Deepest QuickBooks integration in the manufacturing space — two-way sync of inventory, COGS, and purchase orders
• Multi-level BOM with assembly management and work order tracking
• Barcode scanning for shop floor operations and receiving
• On-premise option (Fishbowl Advanced) for manufacturers who need data on their own servers
• Part tracking with lot, serial, and expiration date support

Where it falls short:

• The cloud version (Fishbowl Drive) is relatively new and still catching up to the mature on-premise product
• $349/month puts it in the same bracket as more feature-rich tools like Katana
• Interface feels dated compared to newer cloud-native competitors
• Limited native ecommerce integrations beyond Shopify

Best fit: Manufacturers running QuickBooks as their accounting backbone who want to add manufacturing capabilities without replacing their entire tech stack. Strong in custom manufacturing, food production, and distribution.

4. NetSuite Manufacturing

Best for: Enterprise manufacturers who need a complete ERP with manufacturing, financials, and supply chain in one system.

Starting price: ~$999/month+ (custom quote required)

Oracle NetSuite is the heavyweight in this list. It is a full cloud ERP that includes manufacturing modules for work orders, routing, BOM management, WIP tracking, and demand planning — alongside financials, CRM, procurement, and warehouse management. For manufacturers who have outgrown standalone tools and need everything under one roof, NetSuite is the default enterprise choice.

What it does well:

• End-to-end visibility from raw material procurement through production to finished goods delivery
• Advanced demand planning and supply chain management with MRP and MPS capabilities
• Global multi-subsidiary support with consolidated reporting across entities and currencies
• Customisable workflows through SuiteScript and SuiteFlow
• Broad integration ecosystem including native connections to Oracle NetSuite ERP

Where it falls short:

• Pricing starts high and scales with modules, users, and transactions — expect $2,000–$5,000+/month for a full manufacturing setup
• Implementation takes 3–6 months with a dedicated partner, plus significant upfront consulting fees
• Overkill for manufacturers under $5M/year in revenue
• The learning curve is steep — NetSuite is powerful but not simple

Best fit: Manufacturers doing $10M+ in revenue with complex operations spanning multiple facilities, subsidiaries, or countries. If you need manufacturing, financials, and CRM in a single database with real-time reporting, NetSuite is hard to beat.

5. Unleashed

Best for: Mid-market manufacturers focused on batch production and lot traceability.

Starting price: $349/month (Medium plan)

Unleashed (now part of MYOB) specialises in inventory management for manufacturers and distributors who need precise traceability without the complexity of a full ERP. Its strength is in batch manufacturing — tracking raw materials through production runs, managing lot numbers, and maintaining full traceability from supplier to customer.

What it does well:

• Batch and lot traceability with expiry date tracking — essential for food, cosmetics, and pharmaceuticals
• Assembly and disassembly workflows with multi-level BOM support
• Strong reporting including inventory valuation, production costs, and margin analysis
• Xero and QuickBooks integration for accounting
• API-first architecture for custom integrations

Where it falls short:

• $349/month minimum is expensive for small manufacturers
• Production scheduling is basic compared to dedicated MRP tools like Katana or MRPeasy
• No built-in capacity planning or shop floor management
• The MYOB acquisition has created some uncertainty about product direction

Best fit: Manufacturers producing batch goods (food, beverages, cosmetics, supplements, chemicals) who need bulletproof traceability and compliance documentation. Also suits distributors who do light assembly or kitting.

6. inFlow Manufacturing

Best for: Small workshops and light manufacturers who need simple, affordable inventory management.

Starting price: $89/month (Entrepreneur plan)

inFlow started as a simple inventory management tool and has steadily added manufacturing capabilities. It will not compete with dedicated MRP systems on production planning, but for small manufacturers who need BOM management, work orders, and basic production tracking without the complexity (or cost) of a full MRP system, inFlow hits a sweet spot.

What it does well:

• Simple BOM and assembly management — build finished products from components with a few clicks
• Barcode scanning via mobile app for receiving, picking, and production
• Affordable pricing — $89/month covers most needs for small teams
• Intuitive interface with minimal training required
• Built-in B2B ecommerce portal for wholesale orders

Where it falls short:

• No MRP or material requirements planning — you manage reorder points manually
• Limited production scheduling (no Gantt charts or capacity planning)
• Single-level BOM only on lower tiers
• No lot traceability on the base plan
• Not suitable for complex multi-stage manufacturing

Best fit: Small manufacturers with under 500 SKUs and simple production processes — think custom furniture makers, small food producers, craft breweries, or light assembly operations. If you are graduating from spreadsheets, inFlow is a logical first step.

7. Cin7 Core

Best for: Manufacturers who sell through multiple channels and need production plus sales management in one platform.

Starting price: $349/month

Cin7 Core (formerly DEAR Systems) bridges the gap between manufacturing and sales. Unlike pure MRP tools, it combines production management with multi-channel sales, warehouse management, and B2B portals — useful for manufacturers who sell directly to retailers, wholesalers, and online marketplaces.

What it does well:

• Production + sales in one system — manage BOMs, work orders, and finished goods alongside purchase orders, sales, and fulfilment
• Multi-channel selling with integrations to Shopify, Amazon, eBay, and WooCommerce
• Auto-assembly triggers — automatically create manufacturing orders when finished goods stock drops below threshold
• Landed cost tracking with allocation across line items
• Strong accounting integrations with Xero and QuickBooks

Where it falls short:

• $349/month is the entry point — advanced features push costs higher
• Production scheduling is functional but not as sophisticated as Katana or MRPeasy
• The rebrand from DEAR Systems to Cin7 Core created confusion in the market
• Can be complex to set up with many modules to configure

Best fit: Manufacturers who also operate as distributors or D2C brands — companies that make products AND sell them across multiple channels. Strong for consumer goods manufacturers managing wholesale, retail, and ecommerce from one system.

8. SAP Business One

Best for: Complex manufacturers who need industrial-grade MRP with deep customisation.

Starting price: Custom quote (typically $3,000–$5,000+/month for manufacturing setup)

SAP Business One is the small-to-midsize offering from SAP, the company behind most of the world’s largest manufacturers’ ERP systems. It brings enterprise manufacturing discipline — MRP, capacity planning, quality management, and engineering change management — in a package designed for companies with 50–500 employees. OneCart integrates with SAP Business One for manufacturers who also sell through online marketplaces.

What it does well:

• Full MRP with capacity planning — forward and backward scheduling, bottleneck analysis, and “what-if” scenarios
• Engineering change management for regulated manufacturing (medical devices, aerospace)
• Deep customisation through SAP’s partner ecosystem
• Multi-facility planning across warehouses and production sites
• Proven track record — SAP has been serving manufacturers for 50+ years

Where it falls short:

• Pricing is opaque — licensing, implementation, hosting, and partner fees add up quickly
• Implementation takes 6–12 months with a certified SAP partner
• The interface, while improved, still feels enterprise-heavy
• Significant overhead for simple manufacturing operations
• Ongoing maintenance and upgrade costs

Best fit: Manufacturers in regulated industries (medical devices, aerospace, automotive, food processing) who need compliance documentation, engineering change control, and audit trails. Also suits manufacturers planning to scale into the enterprise tier.

9. OneCart

Best for: Manufacturers who sell finished goods online through multiple marketplaces.

Starting price: S$48/month (~$36 USD)

OneCart is not manufacturing MRP software — it does not do production planning, BOM management, or shop floor scheduling. But it solves a problem that many manufacturing tools ignore: getting your finished goods to market across multiple online channels. If you manufacture products and sell through Shopee, Lazada, Amazon, TikTok Shop, or your own Shopify store, OneCart keeps inventory synchronised in real time across all platforms.

What it does well:

• Real-time inventory sync across 13 platforms — including Shopee, Lazada, Amazon, TikTok Shop, Temu, and Shopify
• Consolidated order management — all marketplace orders in a single dashboard
• Prevents overselling with automatic stock adjustments as orders come in across channels
• ERP integrations — connects to NetSuite, SAP Business One, Xero, and QuickBooks to pull manufacturing data into the sales workflow
• Pricing starts at $36 USD/month — a fraction of the cost of adding marketplace modules to your MRP system

Where it falls short:

• No production planning, BOM management, or manufacturing workflow features
• Not a standalone solution for inventory management — works best alongside an MRP/ERP system
• Strongest in Southeast Asian marketplaces (Shopee, Lazada) with growing global coverage

Best fit: Manufacturers who have production sorted but need help with the sales side — syncing finished goods inventory across Shopee, Lazada, Amazon, TikTok Shop, and other marketplaces without manual updates. Pairs naturally with any MRP tool on this list.

How to Choose the Right Manufacturing Inventory Software

Picking the wrong tool costs more than money — it costs months of implementation time and operational disruption. Here is a framework for narrowing down your options:

Start with your production complexity. If you have simple BOMs (under 3 levels) and straightforward assembly, inFlow or Fishbowl will serve you well. Multi-level BOMs with subcontracting, quality control, and capacity planning need a proper MRP system like Katana or MRPeasy. Regulated industries (medical, food, aerospace) should look at SAP Business One or NetSuite for compliance features.

Consider your team size. Per-user pricing (MRPeasy) favours small teams. Unlimited-user pricing (Katana) favours growing teams. Enterprise tools (NetSuite, SAP) have complex pricing that rewards scale.

Map your sales channels. Pure B2B manufacturers selling through distributors have different needs from D2C manufacturers selling on marketplaces. If you sell online, you need either a tool with built-in ecommerce integrations (Katana, Cin7 Core) or a dedicated multichannel management platform like OneCart alongside your MRP.

Check your accounting integration. If you run QuickBooks, Fishbowl is purpose-built for that integration. Xero users should look at Unleashed or MRPeasy. NetSuite and SAP have their own built-in accounting.

Budget honestly. Factor in not just the subscription but implementation, training, data migration, and ongoing customisation. A $49/month tool with zero implementation cost may deliver better ROI than a $3,000/month ERP that takes 9 months to go live.

Actionable Insight: Before committing to any tool, run a 30-day pilot with your actual data. Most manufacturing inventory tools offer free trials — use them with real BOMs, real production orders, and real inventory counts, not demo data.

Frequently Asked Questions

What is the difference between inventory management software and MRP software?

Standard inventory management software tracks stock levels, locations, and movements — how much you have and where it is. MRP (Material Requirements Planning) software adds a manufacturing layer: it takes your BOMs, production schedule, and sales forecasts to calculate what raw materials you need, when to order them, and when to start production. Every MRP system includes inventory management, but not every inventory system includes MRP. Manufacturers with production processes need MRP; those who only assemble or distribute may be fine with standard inventory tools.

Can small manufacturers use these tools, or are they only for large factories?

Several tools on this list are specifically designed for small manufacturers. MRPeasy starts at $49/user/month and serves workshops with as few as 1–2 users. inFlow at $89/month handles simple assembly operations. Katana’s free tier works for testing with up to 30 SKUs. The days when manufacturing software meant a $100,000+ ERP implementation are long gone — cloud tools have made proper manufacturing inventory management accessible to businesses of all sizes.

How does manufacturing inventory management differ from retail inventory management?

Retail inventory tracks finished products ready for sale — units in, units out, reorder when low. Manufacturing inventory manages three categories simultaneously: raw materials (inputs), work-in-progress (partially completed products on the production line), and finished goods. You also need to manage BOMs, production routing, yield rates (not every input becomes a finished product), and supplier lead times for raw materials. The complexity grows exponentially with multi-level BOMs and multiple production stages.

Do I need separate software for manufacturing and selling online?

It depends on your sales model. If you sell purely B2B through distributors, your MRP/ERP system likely handles sales orders and invoicing. But if you sell D2C through Shopee, Lazada, Amazon, TikTok Shop, or Shopify, you need either an MRP with native marketplace integrations (Katana, Cin7 Core) or a dedicated multichannel tool like OneCart alongside your manufacturing system. The key is keeping finished goods inventory synchronised — selling the same stock on five platforms without a sync layer is a recipe for overselling.

What features should I prioritise in manufacturing inventory software?

For most manufacturers, these five features are non-negotiable: (1) Multi-level BOM management, (2) Work order and production tracking, (3) Purchase order management with supplier lead time tracking, (4) Lot or serial number traceability, and (5) Integration with your accounting system. Beyond these, prioritise based on your specific needs: capacity planning for complex production, safety stock formulas for demand variability, or multi-location support if you operate across facilities.
