What this calculator compares
Most “compare inventory software” pages stack three feature cards and a starting price. That hides the actual bill. Two vendors with the same “from $29/month” headline can be hundreds of dollars apart once your catalog or order volume crosses a cap.
This page is a working estimate: one catalog size, one order volume, five published price lists. It is not a substitute for a quote — Cin7 Omni, Sortly Enterprise, inFlow Enterprise, and StockFlow Enterprise+ are custom — but it is the number you can take into a demo and ask them to beat.
How we priced each vendor
Prices were read from each public pricing page on 2026-09-04. Currency is USD. Taxes are excluded, matching how the vendors present their plans.
| Vendor | What the plan actually caps | Published list (monthly) | Billed yearly (per month) |
|---|---|---|---|
| StockFlow | 25 / 2,000 / 5,000 / 10,000 unique products. No order cap. | $0 / $19 / $39 / $79 | $0 / $15.83 / $32.50 / $65.83 |
| Sortly | 100 / 500 / 2,000 / 5,000 unique items | $0 / $49 / $149 / $299 | $0 / $39.20 / $119.20 / $239.20 (ongoing 20% off) |
| Zoho Inventory (US) | 50 / 500 / 3,000 / 7,500 / 15,000 orders per month. SKUs unlimited. | Not published (billed-annually only) | $0 / $29 / $79 / $129 / $249 |
| inFlow Inventory | Unlimited products, sales and purchases. Lite 2 users / 1 location; Core 5 / 5; Pro 10 / unlimited; Max 20 / unlimited. | $129 / $379 / $629 / $879 | $99 / $299 / $499 / $699 |
| Cin7 Core | 6,000 / 24,000 / 120,000 sale orders per year. SKUs under 100,000. | $349 / $599 / $1,199 | Same listed USD/month price |
Sortly currently advertises 50% off the first year of new yearly plans ($24 / $74 / $149). This calculator uses the ongoing yearly rate so a renewal is not a surprise. Zoho add-on prices were not shown on the official pricing page (checked 13 Oct 2026). inFlow add-ons (lots, serials, extra seats) are not included — only the base plan that fits your product and order counts.

How to choose after you have a number
Price is the filter, not the whole decision. Use the calculator to drop anything that is 10× your budget, then compare the remaining tools on the work you actually do: receiving, barcode counts, transfers, and whether you hit an order cap every busy month.
- Under 25 products: start on a free plan. StockFlow, Sortly, and Zoho all have one. The difference is the cap you will hit first — products (StockFlow/Sortly) or orders (Zoho).
- A few hundred SKUs, light order volume: StockFlow Professional at $19/month is usually the lowest paid option that still has no monthly order ceiling.
- Visual asset-style tracking: Sortly is built for photo-led item catalogs. Expect the bill to follow unique item count, not orders.
- Already in the Zoho suite: Zoho Inventory stays inexpensive until order volume grows. The free plan’s 50-order cap is the usual tripwire.
- Wholesale ops that need receiving and POs as a system: inFlow starts at $129/month billed annually, with products unlimited and orders capped on the first two tiers.
- Omnichannel, EDI, 3PL: Cin7 Core starts at $349/month. That is a different buyer than a team leaving spreadsheets.
