Fulfil vs Katana (2026): which should you pick?

Pick Fulfil if

• Fits if you run a Shopify Plus brand and want inventory and accounting together
• Works for brands with EDI and 3PL partners

Look elsewhere if

• Skip it if you are a very small seller, as it is aimed at brands with meaningful volume
• Not for you if you want a price, since a quote follows a demo
• Pricey if you count the fixed implementation fee on top of the subscription
• Skip it if you want to try free, because the only safety net is a 90-day refund

Pick Katana if

• Fits if you make your own products and need bills of materials and work orders
• Works for food and cosmetics makers who must trace batches for recalls

Look elsewhere if

• Skip it if you want to see a price before booking a sales call
• Tight if you're staying free, as the 30 SKUs count every variant and material
• Not for you if your team wants native phone apps rather than a browser app
• Watch out: the paid plan is sold as one yearly contract, with no monthly option on record
• Watch out: the free plan has no live support, only the AI assistant and knowledge base

Fulfil

• No prices are published; a quote follows one demo and depends on order volume, channels and complexity.
• Implementation is a fixed fee agreed after scoping, on top of the subscription.
• The vendor says a 90-day money-back guarantee covers subscription and implementation fees.
• Aimed at brands with meaningful order volume, so very small sellers may find it more than they need.

Katana

• No price is published beyond the free plan: Advantage is quoted after a scoping call and sold as one annual contract.
• The free plan stops at 30 SKUs, counting each product or material variant, and has no live support.
• There are no native phone apps; the warehouse app runs in a mobile browser at wh.katanamrp.com.
