Prices are the entry list prices each vendor publishes on its own US pricing page, read on Oct 27, 2026. They exclude taxes, payment processing unless stated, hardware, add-ons and negotiated discounts; a promotion appears only in the notes, labeled as one. Prices change. No vendor paid for a place or a price in this table.
Put simply, this pair splits on one fact about your business: do you make the products you sell? Katana is positioned for makers and light manufacturers who need visibility over materials, production and finished goods. inFlow Inventory is positioned for small and midsize businesses running a focused inventory, purchasing, sales order and barcode workflow. Answer the question and the choice follows.
Verdict: inFlow Inventory, unless you manufacture
For the reseller, a shop, distributor or ecommerce brand that buys goods ready to sell, we pick inFlow Inventory. The work that matters to that business, from receiving against a purchase order to scanning stock out, is what inFlow's scope is positioned around.
Katana wins for the maker. A candle company, a small food producer, a furniture workshop or an apparel brand doing its own cut and sew needs to know which materials are committed to which batch and when finished goods will be ready. That is the job Katana is built around.
Why inFlow Inventory wins for resellers
A reseller has no production step to plan, so in our view a production-first system adds screens without adding value. What the reseller needs is a reliable stock record that reacts to every sale and every receipt. For a shop that also sells over a counter, inFlow's Square article describes completed Square orders arriving as sales orders that update stock, along with the cases it does not cover.
In our view inFlow is the wrong base for a business whose margin depends on production planning; if you consider it anyway, check in a trial where work in progress would be recorded.
Why Katana wins for makers
For a maker, the number on the shelf is the end of a chain: materials bought, materials consumed, products finished. Katana's positioning puts that whole chain in one view at the light-manufacturing end, which suits a business without a dedicated planning department. The promise to test in a trial is that the owner sees what is short before the batch starts rather than when it stalls.
Katana is the wrong pick for a business with no production or assembly. Without that work, its central view has nothing to show.
The awkward middle: light assembly
Some resellers bundle products or do simple kitting. In our view occasional bundling fits a stock-first system; confirm it by building one of your bundles in the trial. If bundles become recipes with real materials, scrap and batch timing, the business has crossed into manufacturing, and Katana becomes the better fit.
The deciding test
List your ten best-selling products. Count how many you build or assemble before shipping. If the answer is zero or one, choose inFlow Inventory. If it is most of them, choose Katana. If it is somewhere between, run one recent production or bundling order through a trial of each and see which one shows material shortages before they stop the order.
