Inventory software needs to answer what is available, where it is and what must be purchased or produced next. Retail, ecommerce, wholesale and light manufacturing have different requirements; a storefront platform is not automatically a dedicated inventory suite.

This research-based update checks first-party scope on October 2, 2026. The existing Cin7, Ordoro, inFlow, Katana and Shopify order is retained. We have not tested implementation speed or sync reliability, and there is no universal SKU, revenue or location threshold for upgrading.

1. Cin7 — connected inventory operations

Cin7’s current pricing distinguishes products and plan scope. Quote the required inventory, purchasing, accounting and channel integrations for your workflow rather than assuming the old $349 entry price covers everything.

Decision: consider it when multiple operational systems need coordinated stock records. Ask for a demonstration of your actual channels, returns, bundles and purchasing workflow. Do not assume all integrations are included in every tier.

2. Ordoro — do not confuse shipping with inventory pricing

Ordoro’s pricing separates Shipping, Inventory and Dropshipping. The Inventory product lists $349/month and $499/month tiers with order allowances; the earlier $59–$149 figures belonged to Shipping, not the inventory decision. Purchase-order entitlement also differs by inventory tier.

Decision: price the inventory and shipping combination actually required, including order overages and any other product. Confirm channel compatibility and how returns and bundles affect counts.

3. inFlow — inventory versus manufacturing scope

inFlow’s current pricing distinguishes Inventory, Manufacturing and Stockroom. Inventory Lite is displayed at $99/month and Core at $299/month, billed annually; these are not month-to-month prices. Members, locations and optional features affect the final quote.

Decision: compare purchasing, barcode handling and stock records for your operation. Select Manufacturing separately if assembly and bills of materials are required; do not infer those capabilities from an inventory-only quote.

4. Katana — production and materials requirements

Katana’s current pricing presents a Free option and Core from $299/month. The old $99–$399 range is removed.

Decision: evaluate the required manufacturing, materials and inventory workflow with your actual bill of materials and order channels. A production-oriented tool is not automatically the best fit for a store that only resells finished goods. Obtain the full feature and integration quote.

5. Shopify — built-in inventory within a commerce platform

Shopify is a commerce-platform choice with inventory functionality, not a standalone inventory subscription. Its current plans and location documentation govern platform costs and location limits.

The former table incorrectly said Shopify lacked purchase orders. Shopify’s purchase-order documentation describes supplier details, ordered stock and transfers for receiving inventory. That does not establish parity with every dedicated purchasing/manufacturing suite.

Compare Shopify for a storefront with built-in inventory and purchasing workflows when platform selection is part of the decision. If the storefront is already suitable, do not migrate it just to obtain a different inventory feature.

Validate the operating model before signing

There is no reliable universal “100 SKUs” or “$10K revenue” rule. Choose based on reconciliation errors, channels, warehouses, production steps, permissions and total operating cost.

Define one authoritative stock source with the integration provider. Do not blindly disable Shopify tracking: test stock deductions, reservations, cancellations, returns, bundles and delayed synchronization in the supported configuration. No software guarantees zero overselling.

Request a pilot using representative products and peak-volume scenarios. Migration time depends on data quality, integrations and staff readiness; this guide gives no guaranteed setup timetable.
