Katana Alternatives for Small Manufacturers: 6 Picks 2027

The category decision comes first

If you are replacing Katana, the first decision is the category, not the brand. Do you need a manufacturing system that plans materials and production, or an inventory tool that only tracks stock? A material requirements planning (MRP) system turns sales demand and each product's bill of materials, the parts list and quantities for one finished item, into purchase and production schedules. TL;DR: if your products are built from components, shortlist tools with multi-level bills of materials and work orders. If you only resell finished goods, an inventory tool is probably enough. Among the options below, MRPeasy is the closest like-for-like swap on published pricing and manufacturing scope. Odoo and ERPNext are the better choices if purchasing, accounting and sales must also run in one system.

Key Takeaways

• Decide by what you build: bills of materials, work orders and lot tracking are what separate an MRP from a stock tool.

• Compare units before totals. MRPeasy and Odoo charge per user, while Cin7, Fishbowl and Unleashed charge per plan with included users or licences.

• Check add-ons before the headline price, because MRP, traceability and shop-floor features are sold separately on several plans.

• Katana's own pricing page does not publish its Advantage tier, so get a written quote before you build a budget around it.

• Free and self-hosted options cut licence cost, but hosting, upgrades, backups and support move to your team.

How we evaluated these tools

This is an informed buyer's guide built from public vendor pages, third-party review pages and one industry data source. It is not a hands-on trial, and it does not rank vendors by measured performance. We weighted six criteria for a small shop that builds to order. The weights are our judgment, not vendor data, and a shop that never uses lot tracking should lower that weight. We used the weights to decide what to read first in each vendor's documentation. We did not produce a numeric ranking, because published vendor information is not comparable enough for one. Katana is the reference point rather than a scored alternative.

Who this is for

This article is for the owner or operations lead at a small manufacturer who has decided Katana no longer fits and is close to choosing a replacement. Your size is typical: NAM's summary of Census data says around three-quarters of manufacturing firms have fewer than 20 employees according to National Association of Manufacturers (2022 Census data). Red flags: you need one system across several legal entities or countries, your products need regulated batch records that a tool cannot export, or nobody on your team will own a data migration.

What each vendor publishes for pricing

Katana's Free plan: up to 30 SKUs according to Katana MRP (2026), with unlimited users. Its Advantage plan is a custom annual contract with no published price, so it is Quote-based.

MRPeasy's Professional plan costs $69 per user per month according to MRPeasy (2026). Starter, Enterprise and Unlimited cost $49, $99 and $149 per user per month on the same page, the Unlimited plan requires two users, and extra users come in 10-user bundles at $79 each.

Fishbowl's Essentials plan costs $229 per month, its Growth plan costs $429 and its Scale plan costs $729, all billed annually for inventory use, according to Fishbowl (2026). The page says those inventory plans exclude BOMs, work orders and MRP. Its Advanced Manufacturing plan starts at $675 per month and is confirmed by quote.

Cin7's Standard plan costs $349 per month for five users, its Pro plan costs $599 for ten users, and its Advanced plan costs $1,199 for fifteen users, according to Cin7 (2026). MRP is an add-on on Standard. Advanced Production Manufacturing is an add-on on Pro and Advanced.

Unleashed's Lite plan costs $99 per month or $1,089 per year, its Core plan costs $399 per month or $4,389 per year, and its Pro plan costs $729 per month or $8,019 per year, according to Unleashed Software (2026). Production and manufacturing is a $69 per month add-on on Core and is included on Pro.

Odoo's Standard plan costs $24.90 per user per month and its Custom plan costs $49.00 per user per month, according to Odoo (2026). The per-user fee covers all apps, including Manufacturing. The page shows those as discounted first-12-month rates with higher regular rates beside them, and it does not say outright which billing period each figure applies to, so treat them as introductory rates to confirm.

Frappe's hosted single-site tier costs $5 per month, and ERPNext's software is free to self-host under GPL-3.0, according to Frappe (2026).

Pricing checked October 26, 2026. Quote-based means the vendor does not publish a price, which applies to Katana's Advantage plan and Fishbowl's Advanced tier beyond its starting price.

What five users cost per month

The table multiplies the published list prices above for a five-user team. It excludes add-ons, implementation and hosting, so it is arithmetic on public figures, not a vendor quote.

Two rows need care. Odoo's Standard plan is lowest on paper, but its billing period is not stated and its page does not spell out feature limits, so confirm before comparing. Cin7's Standard plan leaves MRP as an add-on, so its $349 is not a full manufacturing price. Implementation labour appears on none of these pages, so add it yourself to each option before deciding.

Feature matrix, normalized

"Not verified" means this research did not find the feature on a page we opened. It does not mean the product lacks it.

US Tech Automations sits beside these tools rather than inside the matrix. It would read from whichever system you choose, so the gaps in this table decide how much custom reading and writing a proposed design needs.

Vendor profiles

Each profile separates what the vendor publishes from our reading of it.

Katana (the reference point)

Facts: Katana's features page lists BOM and subassemblies, a shop floor app, batch and lot tracking, and barcode-enabled workflows. SoftwareConnect rates Katana 4/5 from 11 reviews according to SoftwareConnect (2026). That listing says manufacturing features carry separate monthly fees and includes one 5-star review whose text is negative.

Our read: Katana is the right choice if your BOMs already live there and the gap is only tracking. It is a weaker choice if the goal is to escape add-on pricing, because add-ons are where the bill grows. Its limits are the 30-SKU Free cap and an Advantage tier you must quote. Choose it if you want the least migration work and can get a written quote.

MRPeasy

Facts: The homepage names MRP production planning, lot or batch tracking, a shop-floor interface, and integrations with QuickBooks Online and Xero. Founded in 2014, the company is led by co-founder and CEO Konstantin Klugman, per its 2024 press release. One hands-on review lists API access as limited to the Unlimited plan, reporting as needing more depth, and no native mobile app, which conflicts with the app-store buttons on the homepage.

Our read: Choose MRPeasy when the shop is manufacturing-first and you want per-user pricing you can model. Confirm the API need before picking a tier, because the review puts API access on the top plan.

Fishbowl

Facts: Fishbowl's inventory plans exclude manufacturing. Its Advanced Manufacturing plan covers BOMs and sub-assemblies, MRP and production scheduling, lot and batch traceability, QuickBooks integrations and an open API. Diversis Capital Management acquired Fishbowl in December 2021, per Private Equity International.

Our read: Fishbowl suits QuickBooks shops that need traceability alongside production planning. Budget the Advanced tier, not the $429 Growth plan, if you need BOMs, and expect a quote because $675 is only a starting price.

Cin7 Core

Facts: Cin7's Standard plan includes assembly manufacturing, BOM tracking, kits, and batch or expiration tracking. MRP is an add-on there, and it is included on Pro. The Advanced Production Manufacturing module is an add-on on Pro and Advanced.

Our read: Cin7 fits teams that mostly need inventory with BOMs and kits rather than full production scheduling. Test whether the MRP add-on is needed before you buy Standard.

Unleashed

Facts: The Access Group announced its acquisition of Unleashed on 13 November 2020, and says Unleashed brings "£9.6m" in revenue and more than 4,000 customers, according to The Access Group (2020). Manufacturing is a $69 per month add-on on Core and included on Pro.

Our read: Unleashed fits wholesalers and distributors with light assembly. Its Lite plan's manufacturing scope is unclear on the pricing page, and this research did not verify Unleashed's manufacturing features beyond those labels, so request a feature walkthrough before shortlisting it.

Odoo

Facts: Odoo's manufacturing documentation describes scheduling manufacturing orders, multilevel BoMs, a work center control panel for shop-floor tablets, a lots and serial numbers workflow, and an external JSON-2 API in version 19.0 docs. Its per-user fee covers all apps.

Our read: Odoo fits a shop that wants accounting, purchasing and sales in one system. It needs more configuration than a dedicated MRP, and its billing period needs confirmation before you compare prices.

ERPNext

Facts: ERPNext is GPL-3.0 licensed and free to self-host, and the Frappe pricing page names a Manufacturing module. Hosting and enterprise support are paid services from Frappe.

Our read: ERPNext fits a team with an in-house IT person who can run upgrades and backups. This research did not verify its BOM, work-order or traceability depth, so check the documentation before shortlisting it.

Where the work breaks after the switch

A proposed workflow for the cut-over, configured by US Tech Automations, would start when a manufacturing order's status changes to DONE in the new system, read that order through the system's API, post the finished quantity and lot number to the accounting ledger, and write any mismatch to a shared exceptions list. Prerequisites are API access on the plan you choose, a key limited to production records, and a named owner for the field mapping. The human review point is a supervisor who clears every exception before the ledger entry is final, so no automated write changes a cost without a person seeing it.

A second proposed workflow handles shortages. If a tool exposes a status field, such as Katana's NOT_STARTED, BLOCKED, IN_PROGRESS and DONE values, a BLOCKED order triggers a purchasing task that names the missing component from the bill of materials. The buyer confirms any purchase order by hand. The prerequisite is a status field on your chosen tool and a purchasing inbox the team already reads.

The DIY route is real. Zapier, Make or n8n can run the same two flows, and when configured properly they keep run histories, retries and error branches that show what happened. The buyer still designs and owns idempotency, so a retry never posts the same order twice, along with escalation paths, access controls and upkeep when an API changes. A proposed US Tech Automations design would configure those pieces as a set and name each review point before go-live. Whether that beats an in-house build depends on who will maintain it.

Worked example: when the Free plan stops fitting

Take an illustrative shop, not a real customer, with 45 SKUs, three users and 120 manufacturing orders a month. Katana's pricing page caps the Free plan at 30 SKUs, so this shop is 15 SKUs over (45 − 30 = 15). If each order is re-keyed into accounting at an assumed 6 minutes, that is 120 × 6 = 720 minutes, or 12 hours a month of copying. A pull job on Katana's manufacturing_orders endpoint returns 50 records per page by default, so 120 orders fit in three pages (120 ÷ 50 rounds up to 3), and the read side is light. The write side needs review. Three users on MRPeasy's Professional plan cost 3 × $69 = $207 per month before add-ons, so the licence math alone does not decide the switch; the 12 hours of copying does.

Common mistakes when switching

• Comparing headline prices without the add-ons that carry MRP, traceability or shop-floor use.

• Assuming API access is on every plan. One review places MRPeasy's API on its top tier only.

• Buying for today's SKU count and ignoring the BOM depth you will need in a year.

• Migrating open orders without a freeze date, so the old and new systems both show the same job.

• Treating a free self-hosted tool as free to run.

• Skipping an export test. Ask the vendor to show a full bill of materials and lot history export before signing.

Glossary of terms in this guide

• Bill of materials (BOM): the parts list and quantities for one finished product.

• Multi-level BOM: a bill of materials that includes sub-assemblies, each with its own parts list.

• MRP: material requirements planning, which turns demand into purchase and production schedules.

• Manufacturing order (work order): an instruction to build a quantity of one product.

• Lot or serial traceability: linking finished goods to the batches or serial numbers of components used.

• SKU: one stock-keeping unit, a distinct item you count and sell.

• Idempotency: a design property where running the same write twice produces one record, not two.

• Add-on: a feature sold separately from the base plan.

Questions buyers ask before switching

Is Katana's Free plan enough for a small shop?

It is enough only for a shop with 30 SKUs or fewer that does not need add-on manufacturing features. The Free plan's cap is set on Katana's pricing page, and the add-ons are separate from it.

Which option is cheapest for five users?

Among paid options on published list prices, Odoo's Standard plan costs $124.50 for five users, but its billing period is not stated. Free ERPNext and Katana's Free plan carry hosting or SKU-cap trade-offs, so the cheapest option on paper is not automatically the cheapest to run.

Do I need an ERP instead of an MRP?

Usually not. An MRP is enough when it covers BOMs, purchasing and inventory, and you need an ERP when accounting, CRM and multi-entity reporting must run in one system.

What does a migration need before go-live?

Export your bills of materials, open orders and inventory counts first, then run both systems in parallel for one full production cycle before you retire the old one.

When NOT to use US Tech Automations?

Skip an automation layer when a native integration or a saved export already covers the handoff you need. The simpler tool wins in three cases: your only handoff is a monthly report that a spreadsheet export covers; the tool you choose already syncs with your accounting system and nobody needs exception handling; or no one will review exceptions, which means an automation adds writes nobody checks.

Making the decision this quarter

Shortlist two options: one manufacturing-first tool and one ERP-leaning tool. Request written quotes for every Quote-based price, starting with Katana's Advantage plan and Fishbowl's Advanced tier. Export one real bill of materials and one lot history from your current system, then import both into each trial before you decide. If you want the two flows above configured against whichever tool you choose, see how US Tech Automations configures this.
