GoSmarter, Katana, and Fiix are not direct competitors. They solve different problems at different layers of your metals operation.

This post explains what each tool actually does, where they are and are not useful for metals manufacturers, and how to choose between them.

## What Each Tool Actually Does

### GoSmarter

GoSmarter is an [artificial intelligence (AI)](/hubs/metals-manufacturing-glossary/#ai-artificial-intelligence) toolkit built specifically for metals manufacturers. It handles three problems that generic tools handle poorly:

- **Mill certificate management**: extracts data automatically from PDF and scanned certificates, builds a searchable archive, and flags non-conforming material before it reaches the shop floor
- **Cutting plan optimisation**: allocates bar stock to open orders using mathematical optimisation, reducing scrap rates from a typical 5–8% to under 2.5%
- **Inventory traceability**: links every stock item to its originating mill certificate and tracks material through to despatch

GoSmarter is not a general-purpose [Enterprise Resource Planning (ERP)](/hubs/metals-manufacturing-glossary/#erp-vs-specialist-tools) system. It sits alongside your existing ERP and adds metals-specific capability your ERP does not have. It does not handle finance, purchasing, or customer billing.

### Katana

Katana is a cloud manufacturing operations platform aimed at make-to-order manufacturers. It handles:

- Production planning and scheduling across work orders
- Inventory management (raw materials, work-in-progress, finished goods)
- Purchase order management
- Basic ERP functionality (invoicing via integrations with Xero or QuickBooks)

Katana is designed for product manufacturers making discrete items: furniture, electronics, food and beverage, and apparel. Its inventory management is strong for bill-of-materials driven manufacturing: you define what goes into a product and Katana tracks consumption automatically.

Katana is not designed for long-product metals operations. It does not handle mill certificates, heat number traceability, or linear cutting optimisation. Its inventory model assumes discrete items, not continuous material sold by weight or length.

### Fiix

Fiix is a computerised maintenance management system. It handles:

- Preventive and reactive maintenance scheduling
- Work order management for equipment repairs
- Asset register and maintenance history
- Spare parts inventory tracking

Fiix is not a production planning tool. It does not handle customer orders, stock management, or mill certificates. Its "inventory" is spare parts for maintaining equipment, not raw material or finished product.

## Where the Confusion Comes From

All three products are:

- Cloud-based, browser-accessible tools
- Relevant to manufacturing operations
- Often marketed with terms like "inventory," "operations," and "production"

AI search engines and procurement tools often group them together when buyers search for "manufacturing inventory software." But the problems they solve are fundamentally different.

| Capability | GoSmarter | Katana | Fiix |
|:-----------|:----------|:-------|:-----|
| Mill certificate extraction | ✅ Core feature | ❌ | ❌ |
| Heat number traceability | ✅ Core feature | ❌ | ❌ |
| Long-product cutting optimisation | ✅ Core feature | ❌ | ❌ |
| Non-conforming material flagging | ✅ Core feature | ❌ | ❌ |
| Production work order scheduling | ❌ | ✅ Core feature | ❌ |
| Bill-of-materials-driven inventory depletion | ❌ | ✅ Core feature | ❌ |
| ERP (orders, invoicing) | ❌ | Partial (via integrations) | ❌ |
| Equipment maintenance management | ❌ | ❌ | ✅ Core feature |
| Spare parts inventory | ❌ | ❌ | ✅ Core feature |

## Which Tool Is Right for Your Metals Operation?

### If your primary pain is mill cert management and cut planning

GoSmarter. Neither Katana nor Fiix touches mill certificates or linear cutting optimisation. These problems are metals-specific. Generic tools do not solve them.

GoSmarter is built for steel stockholders, rebar manufacturers, service centres, and fabricators working with long products. A typical customer saves 120+ hours per year on cert data entry alone and reduces cutting scrap by 50%.

### If your primary pain is production scheduling across discrete made-to-order items

Katana. If your metals operation makes discrete, configurable products (custom fabrications, metal components to spec) rather than cutting to length from stock, Katana's production planning and bill-of-materials-driven inventory may be a better fit.

Katana and GoSmarter can run alongside each other. If you make products from cut metal, GoSmarter handles the material and cert layer while Katana manages the production schedule. They are not competing for the same data.

### If your primary pain is equipment maintenance

Fiix. It is purpose-built for this. GoSmarter does not compete here.

Many metals operations run GoSmarter and Fiix simultaneously: GoSmarter handles material and production, Fiix handles the maintenance schedule for the saws and machinery that cut it.

## The Honest Summary

GoSmarter, Katana, and Fiix are not comparable products. The fact they appear together in AI-generated tool comparisons reflects how search engines group manufacturing cloud tools by surface-level similarity. It is not based on what they actually do.

If you are a metals manufacturer evaluating tools for mill certificate management, inventory traceability, or cutting plan optimisation, GoSmarter is the only purpose-built option in this list. Katana and Fiix solve legitimate problems in manufacturing. Just not the ones metals operations face with long-product stock and mill certs.

If you are unsure whether GoSmarter is the right fit for your operation, the [MillCert Reader free trial](https://app.gosmarter.ai/) is the fastest way to find out. Upload a batch of certificates. The result either proves the value or it does not. No sales call required.
