SKU Compass

Forecasts and tracks inventory across Amazon FBA + AWD, Shopify, and Walmart in one unified view, with 2026 fee math built in and an optional dedicated analyst (managed service). Built for the moment a Shopify brand adds a second channel and spreadsheets stop scaling.

Pick it if: you sell on Shopify plus Amazon or Walmart (or plan to within a year), or you want software and a human watching your numbers. Skip it if: you're strictly Shopify-only with simple demand — you'd be paying for multi-channel muscle you won't use yet.

Inventory Planner

One of the deepest forecasting tools available — rich replenishment recommendations, open-purchase-order management, and detailed demand modeling. It's genuinely multi-channel (Shopify, Amazon, BigCommerce, WooCommerce, and wholesale), long a default for serious Shopify brands that outgrew lighter tools.

Pick it if: you want the deepest self-serve forecasting and your team has the bandwidth to run it without a dedicated analyst. Skip it if: you want Amazon-native fee math (per-FNSKU FBA + AWD) or a managed-service option — that's where SKU Compass differs from it, not on multi-channel support.

Shopify native inventory management

Shopify's built-in inventory features in Shopify Admin — free with your plan, no extra tool to add. Forecasting is basic, but for a Shopify-only brand with a manageable catalog and simple demand it covers the core job. It's also the destination Shopify is migrating Stocky users onto.

Note on Stocky: if you're still on Stocky, it's being discontinued — removed from the Shopify App Store in February 2026 and fully shut down on August 31, 2026 — so it's no longer a tool to adopt. Export your data (especially suppliers, which don't carry over) and migrate. Our Stocky migration guide ranks the alternatives by brand shape.

Pick native Shopify if: you're Shopify-only with simple demand and watching budget. Outgrow it when: you add a channel, your forecasting needs more depth, or inventory lives at 3PLs it can't see.

Cogsy

Built for DTC operators who think about inventory as a cash-flow decision. Strong replenishment planning, purchase-order workflows, and a focus on tying reorders to working capital and growth targets.

Pick it if: you're a DTC brand where cash tied up in inventory is the constraint and you want planning framed around capital. Skip it if: your core problem is multi-channel demand visibility rather than cash-flow planning.

Cin7

An inventory-and-operations platform that goes well beyond forecasting — multi-warehouse, wholesale/B2B order management, accounting integrations, and broader ERP-style workflows. Heavier to implement, but it covers ground a pure forecasting tool doesn't.

Pick it if: you run wholesale + DTC, multiple warehouses, and need an operations backbone, not just a forecast. Skip it if: you want focused, fast forecasting — full ERP is more weight (and cost) than a forecasting-first brand needs.

Katana

Manufacturing-aware inventory: bills of materials, production scheduling, and raw-material tracking alongside finished-goods stock. Purpose-built for brands that make what they sell rather than just reselling finished units.

Pick it if: you manufacture or assemble products and need to track components and production, not just SKUs. Skip it if: you sell finished goods you buy from suppliers — the manufacturing features become overhead you don't need.
