OakNex vs Katana: a detailed comparison.

Katana Cloud Inventory is a well-known cloud MRP with a large footprint across manufacturing verticals — furniture, electronics, apparel, food & beverage among them — and a native, bi-directional Shopify integration. OakNex is a newer, narrower tool built specifically for small EU food and beverage producers: kombucha, kefir, small-batch beverages, ferments. Neither claim makes the other one wrong; they are built for different kinds of manufacturers.

At a glance

	OakNex	Katana Cloud Inventory
Target user	Small EU food & beverage producers, 2–20 people	Small-to-mid manufacturers across many verticals (furniture, electronics, food & bev, cosmetics)
Batch/lot traceability	Built in — every movement is lot-linked from day one	Available as the separate "Full Traceability" add-on on top of Core
Recipe scaling (liquid batches)	Litre-scaled recipes with variable bottle output and joint cost by litres produced	We did not find batch-volume scaling in Katana's published materials, as of July 2026
EU VAT + EN 16931 e-invoicing	Native: domestic/intra-EU/export/OSS VAT engine with VIES checks, UBL 2.1 e-invoices	Not found in Katana's published materials
Shopify sync	Yes — orders, inventory, fulfillment	Yes — native, bi-directional, a mature integration
Pricing (as of July 2026)	Single plan, per workspace — see /pricing	Free plan (30 SKUs) or Core from $299/month (usage-based sales-order billing), plus a $199/month Manufacturing add-on and a separately priced Traceability add-on
Free trial	30 days, full product, no credit card	Free plan is perpetual (30-SKU cap); 15-day grace period for unlimited SKUs, no credit card

Where Katana is the stronger choice

Katana's Core plan bundles unlimited users and unlimited integrations as of its February 2026 pricing revamp, and its Shopify integration is mature and native — it's been a workhorse for online-first manufacturers for years, not a recent add. If you sell across multiple channels beyond Shopify (Amazon, WooCommerce, a B2B storefront) and need a manufacturing tool that plugs into a wide integration ecosystem, Katana's breadth is real and OakNex doesn't try to match it. Katana also ships a public API alongside that integration marketplace; OakNex has no public API today, and Shopify is its one storefront integration — if you need to bolt on a tool we don't natively connect to, that's a real gap.

Katana also spans far more manufacturing verticals than we do — furniture, electronics, apparel, supplements, cosmetics as well as food & beverage. If your business isn't food or beverage specific, or you expect to diversify into other product categories, a generalist tool with a bigger track record and a free tier to start on is a legitimate reason to pick Katana over a category-specific one.

And if you specifically need deep accounting-adjacent integrations, Katana's broader partner network is worth weighing — we don't have an answer for that today (see the FAQ below).

Where OakNex fits better for small EU food & beverage makers

The gap opens in the things a food or beverage producer does every week. Katana prices traceability and manufacturing as separate add-ons stacked on top of its $299/month Core plan — for a small producer that needs both from day one (which most regulated food & bev makers do), the real monthly cost is higher than the headline number. OakNex builds lot traceability, HACCP-style receiving, and FEFO picking into the base product; there's no add-on menu to assemble before you can run a compliant batch.

If you brew, ferment, or bottle a liquid product, OakNex scales recipes by litres of batch volume — the bottling run splits into a variable number of finished bottles by their fill size, and joint cost allocates across those outputs by the litres each one represents. We did not find batch-volume scaling in Katana's published materials, as of July 2026.

And OakNex was built with EU VAT rules as a first-class citizen: domestic, intra-EU goods, export and OSS B2C treatments, VIES number validation, and EN 16931-compliant UBL e-invoices generated directly from a posted shipment — plus native bottle-deposit (DRS) handling for markets that require it. We couldn't find equivalent native EU VAT or e-invoicing features in Katana's own documentation; if that's a hard requirement for your bookkeeping today, it's worth confirming directly with Katana before you commit either way.

Migrating from Katana

Moving from Katana (or any system) to OakNex is real work, not a five-minute import. You're re-entering: your item catalog (with UoMs and net content for bottled goods), your recipes/BOMs, your supplier list and supplier-item pricing, and an opening stocktake to seed accurate on-hand quantities per lot. For a 4-person producer with a few dozen SKUs and a handful of recipes, that's typically a day or two of focused setup, not a project. The trade-off: you're trading a week of data entry for months of not fighting your MRP tool for something it wasn't built to do.
