ReplenishRadar vs Inventory Planner: Shopify-Only Forecasting vs Multi-Channel Planning

Inventory Planner is well-known in the Shopify ecosystem for planning purchases. ReplenishRadar is built for sellers who operate across Shopify and Amazon and want one place to plan reorders and FBA transfers.

TL;DR decision

• Choose ReplenishRadar if you sell on Shopify plus Amazon and want unified planning plus FBA workflows with public pricing.
• Choose Inventory Planner if you are Shopify-only and want a forecasting and purchasing workflow that is deeply centered on Shopify.

What you are actually deciding

1. Channel scope: Shopify-only planning vs unified Shopify plus Amazon planning.
2. Amazon depth: do you need restock limits, transfers, and inbound visibility?
3. Workflow style: action-first outputs vs model tuning and configuration.
4. Pricing: public tiers vs quote-based or varying tiers.

How ReplenishRadar is built for multi-channel operators

ReplenishRadar is designed to reduce planning overhead:

• Unified inventory view across Shopify, Amazon FBA, and warehouse stock
• Demand forecasting and days-to-stockout across channels
• Reorder recommendations tied to lead times and safety stock
• Purchase order drafts and exports
• FBA transfer suggestions and inbound tracking

Where Inventory Planner fits better

Inventory Planner is typically a better fit when:

• Your business is mostly or entirely Shopify.
• You want a planning tool that has been in-market for years and is optimized around Shopify workflows.
• Your team prefers a planning suite that centers on detailed purchasing and reporting inside Shopify context.

Critical differences that matter

Decision factor	ReplenishRadar	Inventory Planner
Primary job	Multi-channel planning for Shopify plus Amazon	Shopify-centered forecasting and purchasing
Amazon FBA workflows	Built-in	Not the core focus
Unified view across channels	Yes	Typically Shopify-first
Setup	OAuth connect	Shopify app
Pricing transparency	Public tiers	Often quote-based or varies by listing

Pricing and onboarding

ReplenishRadar pricing is public by SKU tiers.

Inventory Planner pricing is commonly presented as tailored or quote-based, and can vary based on usage and region. If pricing clarity matters early, ReplenishRadar removes the pricing discovery step.

Bottom line

If you are Shopify-only and want a Shopify-centered planning tool, Inventory Planner can fit. If you are Shopify plus Amazon and want unified planning and FBA workflows with clear pricing, choose ReplenishRadar.
