Unlike generic inventory tools, Katana handles raw materials, work-in-progress, and finished goods. Track what goes into your products, not just what sits on shelves.

Always maintain the right stock at the right time. No stockouts. No excess.

Utilize live data, automation, and smart planning tools to know exactly what’s in stock, where it’s located, and when to replenish — ensuring you deliver every order on time.

Stop guessing what’s in stock

When you’re running production with 50 raw materials and selling through multiple channels, spreadsheets break. One missed update means overselling, stockouts, or production delays.

Katana tracks every item — raw materials, components, and finished goods — across every warehouse and sales channel in real time. When stock moves, the whole team sees it instantly.

We’re going from a small business to a medium sized business. It’s going to be really hard to scale if we can’t track inventory like adults.

From first order to production floor in clicks

When a Shopify order comes in, Katana automatically checks if you have the materials to fulfill it. If yes, it schedules production. If not, it tells you what to order.

  • Auto-import sales orders from Shopify, Amazon, WooCommerce
  • Check material availability before committing to production
  • Generate purchase orders when raw materials run low
  • Track production progress from raw material to shipped product

Bills of materials that actually work

Define what goes into each product — materials, labor, overhead. Katana calculates costs automatically, tracks material consumption, and shows you exactly how much inventory is committed to open orders vs. available for new ones.

  • Multi-level BOMs for complex products
  • Automatic cost calculation per unit
  • Material availability checks before production

Grow without outgrowing your software

Most small manufacturers hit a wall: spreadsheets can’t scale, but ERPs are overkill. Katana grows with you — start with basic inventory tracking, then add production planning, warehouse management, and automation as your business expands.

We’ve already more than doubled our business in the past year. Katana scaled with us without needing to upgrade.
