Buying view: It connects ecommerce demand to manufacturing operations, rather than treating stock planning as only a finished-goods problem. Manufacturing routes, BOMs, stock locations, and channel synchronization must be modeled before sales orders from connected channels are allowed to drive production tasks.

Katana features and workflows

Katana gives product businesses one operating system for sales orders, inventory, purchasing, manufacturing, and warehouse work. Sales and production planners use the Sell, Stock, Buy, and Make screens to see what is in stock, committed, or expected, create purchase or manufacturing orders when supply is short, and move orders toward delivery. Shop-floor and warehouse operators update production, receiving, picking, and packing work, and those changes flow back into the shared inventory record.

Katana use cases

Product businesses that sell, assemble, or manufacture goods need customer orders, stock, purchasing, production, and warehouse execution to stay aligned as priorities and availability change.

How Katana works

Katana is a shared inventory and operations workspace organized around Sell, Stock, Buy, and Make screens, with Shop Floor and Warehouse apps for execution. Sales orders, purchase orders, and manufacturing orders update the same stock states, so planners can decide what to buy, make, or fulfill without reconciling separate spreadsheets.

How Katana supports three supply and fulfillment routes

A sales order or replenishment signal enters Katana, and the item is routed according to its supply model: make to order, make to stock, or resale. The two manufacturing routes share material checking and production, while the resale route checks finished-goods stock; all three reconnect when available inventory is allocated to sales orders, which then proceed through warehouse fulfillment.

If materials or resale stock are short, purchasing and receiving bring them into inventory before the route continues. Production, receipt, allocation, picking, packing, and delivery all update the shared stock and order states used by the next decision.

What each module does and its role

The Katana module descriptions explain the roles of Inventory management, Manufacturing, Order management, and Purchasing.

Inventory management

Inventory management gives planners a Stock screen for products and materials across locations. It shows what is in stock, committed to sales or manufacturing, expected from purchase or manufacturing orders, and below the selected safety-stock level. Sales, purchasing, and production actions update these quantities, so the same stock record supports decisions to buy, make, or fulfill.

Manufacturing

Manufacturing gives production planners a Make screen for manufacturing orders, schedules, ingredient availability, deadlines, and priorities. A make-to-order manufacturing order stays linked to a specific sales order, while a make-to-stock order replenishes future inventory independently. Production staff can work through assigned operations in the Shop Floor App, and completing work records material consumption and adds finished goods to stock.

Order management

Order management gives sales and operations teams a Sell screen for quotes, sales orders, returns, customer records, availability, and delivery status. Orders can be created manually or imported through supported ecommerce connections; planners can change priorities and see how available stock is allocated. Packing or delivering an order updates the shared inventory record and closes the fulfillment loop.

Purchasing

Purchasing gives buyers a Buy screen for purchase orders and supplier delivery status. They can create an order from a shortage shown in a sales order, manufacturing order, or the Stock screen, then set the supplier, quantity, lead time, and receiving location. Receiving all or part of a purchase order adds the goods to stock and makes them available to production or customer orders.

Warehousing

Warehousing gives managers and operators a Warehouse app for receiving, picking, packing, and transfers across locations. Managers assign work, while operators complete tasks and use barcode-supported stock counts, adjustments, and movements. Completed warehouse actions update Katana's inventory state so order and replenishment decisions use current location-level quantities.

Integrations

Integrations connect supported ecommerce, accounting, shipping, and other business tools to Katana. Connected sales channels can bring orders into Katana and keep applicable order or stock records synchronized, while the open API supports custom data flows. Each connector has its own objects, direction, and setup requirements, so behavior must be checked for the systems a business plans to use.

Selection advice

Evaluating Katana when materials, production and inventory need coordination

Consider Katana when sales orders, materials and production need a shared daily workflow. Evaluate Free within its 30-SKU limit, or ask for an Advantage annual quote covering the integrations and implementation you need. Existing subscribers should confirm their current contract.

Comparing Fishbowl when material planning and production scheduling are essential

If material requirements planning, subassemblies and work orders are essential, compare Fishbowl Advanced Manufacturing. Its published scope explicitly includes those manufacturing functions, while Fishbowl’s Inventory product does not include the same capabilities. Compare the actual production workflow and required modules with Katana rather than comparing only brand names or starting prices.

Comparing Cin7 and Finale when channel orders or warehouse work take priority

If the business priority shifts toward multichannel orders, purchasing and distribution, compare Cin7; for receiving, scanning, picking and counts, compare Descartes Finale. Assess both against the actual channel and warehouse workflows. Before replacing Katana, establish which product capabilities will cover the existing materials, production and traceability requirements.

Evaluating Netstock separately when only forecasting and replenishment planning are missing

If existing inventory and production workflows fit but forecasting and replenishment planning need strengthening, evaluate Netstock as a planning tool. It uses business-system data for supply and demand recommendations; buying it as a planning tool is different from replacing the system that holds daily inventory or production records. Whether it can work with the current Katana environment depends on available connections and data transfer methods, which need confirmation before buying the combination.

Misleading pricing, they advertise their core plan at around $299 a month. Which is what we signed up for for our trial. We found out that most of their features were not practical, but we found just hardly enough to justify even that price for at least a limited time. However once the trial ends, they lock you out of some of the most important data and force you to add basic features as add-ons until your price supersedes over $1,000 a month. And by ad-ons, I mean bin locations, and lot numbers, both of which require 2 separate add ons. Now we're unable to download this information and the only support you have is an AI chat-bot that seems to not even understand which MRP it's even on. Most to every other MRP here is significantly cheaper and provides the same features. We were just shopping around and were deciding on Katana. Not anymore. I can just have someone build our own app, or just use google sheets... Both of which are far more reasonable to use despite the slight inconvenience.

Our Experience with Katana MRP – Why We Left After 6 Years We were early adopters of Katana MRP, using it as our primary manufacturing resource planning system for over six years. In the beginning, Katana delivered exactly what we needed - solid functionality, reasonable pricing, and an easy-to-use interface that worked well for a small manufacturer like us with modest sales order volume. Initially, the pricing was fair and manageable. But once Katana began taking on outside investment and aggressively scaling, things started to change. Over time, they revamped their pricing model multiple times. At first it was tied to relatively simple metrics like number of users, but later it shifted to limits based on sales order line items, then to sales orders and gross merchandise value (GMV). What sounded sophisticated in their marketing quickly became a huge headache for us: as a small shop selling mostly items around $10 each, our high order count, not our actual revenue, automatically bumped us into higher pricing tiers. So we ended up paying almost the same as companies doing $50 million+ in annual sales, despite using a fraction of the features and resources. We’ve also experienced price changes mid-subscription period without meaningful notice, and being forced into annual negotiations simply to keep our plan. Year after year, it became clear that the company didn’t care about smaller customers anymore: their strategy seems squarely aimed at upmarket customers with big order volume and deep pockets - which pits small manufacturers like us at a disadvantage. Frankly, the model feels punitive, not proportional. If your business sells a lot of small-ticket orders, you get punished with pricing far beyond the value you actually consume - and that’s simply not sustainable for a real small manufacturer. In the end, after dealing with repeated increasing costs and painfully going around in circles with account reps who didn't take the time to understand our business, we pulled the plug and took the time and effort to migrate to a different MRP that met all our requirements. It is faster, easier to use, and roughly ¼ of the cost of Katana’s current pricing. That switch has been night and day for our team - not only financially but also operationally. On the plus side, Katana made it easy for us to export our data and we performed the data migration and cut-over to the new system entirely in-house. Bottom line: Katana may still work for some companies, especially larger, growing SMBs with high-priced items and few orders, but for small manufacturers with many sales orders and modest item prices, their current pricing strategy simply doesn’t make sense anymore.

The integration is very simple and easy to set up! I wish we could carry tags from Shopify to Katana as well as delay the synch, so it is not automatic. However, we were able to find work around and the app works great overall.
