Katana vs Deelo: Which MRP Is Right for You?

If you are a small manufacturer comparing Katana and Deelo, you are probably at the point where spreadsheets have stopped working and you want a real MRP -- but you are not sure whether you need a dedicated manufacturing tool or something broader.

Here is the honest, one-paragraph answer. Katana is an excellent cloud MRP, purpose-built for product businesses that run on Shopify and QuickBooks, with some of the smoothest storefront and accounting integrations in the category. Deelo takes a different shape: its Manufacturing app delivers comparable MRP -- multi-level BOMs, work orders, Gantt scheduling, costing -- but it lives inside a platform of 50-plus business apps, so your inventory, invoicing, accounting, and CRM are native rather than integrated. If you already love your Shopify-plus-QuickBooks stack and just want manufacturing bolted on, Katana is a natural fit. If you would rather replace the stack itself and run everything on one login and one bill, Deelo is built for that. The rest of this comparison shows exactly where each one pulls ahead.

Credit where it is due -- Katana is a well-built product with a clear point of view. It was designed for makers and direct-to-consumer brands, and it shows in the details.

Its integrations are the headline. Katana connects tightly to Shopify, WooCommerce, and BigCommerce on the sales side, and to QuickBooks Online and Xero on the accounting side. For a brand whose orders originate in an online store and whose books live in QuickBooks, sales orders flow into production and finished goods flow back into sellable stock with very little friction.

The production experience is clean. Real-time inventory across locations, multi-level BOMs, manufacturing orders, and a visual planning view make it approachable for a team without a dedicated production planner. The learning curve is gentle by MRP standards.

Katana also has an open API and a decent app ecosystem, so technical teams can extend it. If your requirement reads like modern MRP that plays nicely with the ecommerce and accounting tools we already use, Katana is one of the strongest answers on the market -- and this comparison is not going to pretend otherwise.

Deelo's argument is not that it is better MRP than Katana. It is that the MRP is one app in a suite you would otherwise assemble from four or five vendors.

Deelo Manufacturing handles the same core jobs -- multi-level BOMs with sub-assemblies, component explosion, where-used lookup, and version control; production work orders across a full lifecycle; a Gantt scheduler with drag-to-reschedule and capacity heatmaps; batch and lot traceability; and real-time material, labor, and overhead cost variance. Make-to-order and make-to-stock are configurable per product, and make-to-order can generate work orders straight from a sales order.

The difference is what surrounds it. Deelo Inventory, Invoicing, and Accounting are separate apps on the same platform, sharing one database of customers, products, and ledger entries. There is no connector syncing your MRP to your books overnight and occasionally failing; job costs post directly. When a customer in the CRM places a wholesale order, the whole chain -- order, work order, stock deduction, invoice, revenue -- runs inside one system.

For a small shop, the appeal is fewer moving parts, one vendor, one bill, and no integration tax. That is the trade Deelo asks you to consider.

A note on reading this table. The starred prices are approximate published starting points as of 2026 -- check current pricing with each vendor, because all of them change it, and entry tiers often cap the users or features you will quickly outgrow. MRPeasy and Fishbowl are in the table because they are the next two names most small manufacturers weigh alongside Katana and Deelo, and the pattern they share is the whole point of this comparison: each is a capable, focused manufacturing tool, but the accounting and CRM live somewhere else that you connect and maintain. Deelo is the only row where inventory, accounting, invoicing, and CRM are native apps on the same platform. Keep that structural difference in mind as you read the rows above -- a checkmark that depends on a third-party integration you own and babysit is not quite the same thing as a capability that is simply built in.

Both tools handle multi-level BOMs, which is the baseline any real MRP has to clear. The difference is at the edges.

Katana gives you clean multi-level BOMs and manufacturing orders with an approachable interface. For most product businesses, it is more than enough -- you define what a product is made of, including sub-assemblies, and Katana explodes the requirements when you schedule production.

Deelo matches that and adds a few things a growing shop tends to want next: BOM version control so you can track engineering changes over time, a where-used lookup to see every product a given component feeds into (invaluable when a supplier discontinues a part), and a shop-floor operator view with barcode scan start/stop, punch in/out, and OEE metrics. Work orders in Deelo move through a full lifecycle -- draft, scheduled, in progress, completed -- and can be created in bulk from a BOM-validated CSV when you need to spin up hundreds at once.

If your BOMs are simple and stable, the two are close. If you have frequent engineering changes, deep sub-assembly trees, or a real shop floor to track, Deelo's extra depth starts to matter.

Inventory is where the all-in-one difference gets concrete. In both tools, building a product decrements the components it consumes -- that is table stakes. Katana does this well across multiple locations and keeps sellable stock in sync with your storefront.

The divergence is costing and where the numbers land. Deelo tracks material, labor, and overhead per work order and runs actual-versus-standard variance analysis, then rolls those costs into the general ledger in the native Accounting app. There is no export step, because the ledger is part of the same platform. When you close a job, the cost of goods is already where your accountant needs it.

Katana tracks manufacturing costs too, but because your accounting lives in QuickBooks or Xero, the financial side depends on that integration staying healthy and mapped correctly. For many teams it works fine. For others, the reconciliation between the MRP's view of cost and the accounting system's view of cost becomes a recurring month-end chore. The question to ask yourself: how much do you value your production costs and your books being the same system rather than two systems that agree most of the time?

This is the philosophical core of the comparison, so it is worth stating plainly.

Katana's model is best-of-breed. It assumes you want to pick the best storefront (Shopify), the best accounting (QuickBooks or Xero), and the best MRP (Katana), and wire them together. When each tool is strong and the integrations are solid -- and Katana's are -- this model is powerful and flexible. The cost is that you are the systems integrator: you own every connection, every field mapping, and every sync that breaks.

Deelo's model is consolidation. Manufacturing, Inventory, Invoicing, Accounting, CRM, and 45-plus other apps are one platform sharing one data model. There is nothing to integrate between them because they were built to be one system. The cost of this model is the inverse: Deelo may not have a specialized third-party integration for every niche tool you use, because the intent is to replace those tools rather than connect to them.

Neither model is universally right. If your existing stack is excellent and you want to keep it, Katana respects that. If your stack is a source of friction and you would happily retire most of it, Deelo is the bigger swing.

Compared on the MRP alone, the two are different pricing shapes: Katana starts around $179 per month on its entry tier, billed annually, and rises with add-ons and users; Deelo starts around $19 per user per month for the entire platform (both as of 2026 -- check current pricing, because both change it).

But the MRP alone is the wrong comparison, and it flatters neither tool. The real comparison includes everything the MRP has to connect to. With Katana, budget for Katana plus QuickBooks or Xero plus whatever CRM, invoicing, and other tools your business runs -- several subscriptions that you also spend time integrating and maintaining. With Deelo, the accounting, invoicing, and CRM are already included in that per-user platform price.

So the question is not which MRP is cheaper. It is what your whole software bill looks like under each model. For a shop that already owns and likes its other tools, Katana can be the more sensible spend. For a shop assembling its stack from scratch, or tired of paying and maintaining five subscriptions, Deelo usually comes out ahead on total cost -- and on the number of vendors you have to deal with.

Choose Katana if your business runs on Shopify or WooCommerce, your books are firmly in QuickBooks Online or Xero, and you want a focused, well-integrated MRP that respects the stack you have already built. It is a genuinely good product for that profile, and switching away from tools you like has a cost of its own.

Choose Deelo if you want manufacturing and the back office it depends on -- inventory, invoicing, accounting, CRM -- to be one system on one bill, and you would rather retire subscriptions than integrate them. Choose Deelo, too, if you value native costing that posts straight to the ledger, deeper quality and traceability workflows, or the option to grow into 50-plus apps without adding vendors.

Both are far better than the spreadsheet you are probably escaping. The deciding factor is rarely a single feature. It is whether your strategy is to assemble a best-of-breed stack and maintain it, or to consolidate onto one platform and stop. Katana is the best expression of the first strategy for small manufacturers. Deelo is built for the second.
