ReplenishRadar vs SoStocked: Amazon-Only Forecasting vs Unified Multi-Channel Planning

ReplenishRadar vs SoStocked: Amazon-Only Forecasting vs Unified Multi-Channel Planning

SoStocked is built primarily for Amazon sellers. ReplenishRadar is built for sellers who run Amazon plus a Shopify store and want one coordinated plan.

TL;DR decision

  • Choose ReplenishRadar if you sell on Shopify plus Amazon and need one unified inventory view, coordinated forecasting, and transfer planning.
  • Choose SoStocked if you are Amazon-only and want an Amazon-first tool and workflow.

What you are actually deciding

  1. Scope: Amazon-only optimization vs multi-channel coordination.
  2. Coordination: do you need to prevent Shopify sales from stealing inventory that Amazon needs, and vice versa?
  3. Workflow: transfer planning and inbound visibility tied to both channels, or Amazon-only.
  4. Pricing and onboarding: self-serve trial vs sales-led onboarding.

How ReplenishRadar is built for Shopify plus Amazon

ReplenishRadar treats Shopify and Amazon as one planning problem:

  • Unified inventory view across Shopify, Amazon FBA, and warehouse stock
  • Forecasting that accounts for both channels in one plan
  • Reorder recommendations tied to lead times and safety stock
  • FBA transfer suggestions that consider what Shopify still needs
  • FBA inbound tracking and reimbursement visibility

Where SoStocked fits better

SoStocked is typically a better fit when:

  • Amazon is your only channel, and you want an Amazon-first planning workflow.
  • You want a tool that prioritizes Amazon constraints and reporting.

Critical differences that matter

Decision factor ReplenishRadar SoStocked
Channel scope Shopify plus Amazon Amazon-first
Unified multi-channel view Yes Not the focus
Coordinated forecasting across channels Yes Amazon-only by default
Transfer planning Coordinated with Shopify needs Amazon-focused
Pricing discovery Public tiers Pricing details are not always shown as a simple self-serve tier list
Trial and onboarding Self-serve trial Often demo or sales-led onboarding

Pricing and onboarding

ReplenishRadar pricing is public and self-serve.

SoStocked's pricing and trial terms are not always presented as simple self-serve tiers across all of their pages. In practice, many sellers should expect a demo or sales conversation as part of evaluation.

Bottom line

If you are Shopify plus Amazon, unified planning wins—choose ReplenishRadar. If you are Amazon-only and want an Amazon-first workflow, SoStocked can fit.
