Live inventory for small manufacturers - know what you can make, sell, and promise, in real time.
Reviewed by Tom · Founder & lead reviewerEvery maker hits the same wall: the spreadsheet says you have 40 units of material, the shelf says 12, and a big order just sold on a promise the shelf can't keep. Katana replaces the spreadsheet with a live system - sales orders reserve materials, production consumes them, purchases replenish them - so 'can we make this by Friday?' becomes a screen you check instead of a walk to the stockroom and a prayer.
The visual production board is the daily driver: what's queued, what's blocked on materials, what ships this week, color-coded and drag-manageable. Connect the store and the loop closes - a Shopify order lands, materials commit, the make list updates, and finished stock flows back to saleable inventory without a human retyping anything. Setup week is real work (accurate BOMs, honest stock counts), and it repays itself the first time the system blocks an oversell you didn't see coming.
The buying trigger is pain math: when a month's stockouts, overselling apologies, and Sunday inventory counts cost more than ~$199, Katana pays for itself - for growing product brands that's earlier than it sounds. Pre-revenue makers and micro-batch hobbyists should stay on spreadsheets a little longer, honestly. And if you're juggling multiple factories and compliance-grade traceability, you're shopping a tier up entirely.
Small makers and product brands who build what they sell - and have outgrown the spreadsheet that pretends to track it.
