Platform Features

Everything You Need to Forecast Smarter

Built for brands managing real inventory complexity — not just a spreadsheet dressed up as software.

Demand Forecasting

Predict future demand using historical sales velocity, seasonal trends, and custom parameters across every channel.

FBA Restocking & Reorder Points

Auto-calculate reorder points using real lead times, safety stock, and days of supply — updated as your velocity changes.

Purchase Order Management

Create, track, and manage POs directly inside SKU Compass — from reorder trigger through inbound receipt at FBA.

Stockout Prevention Alerts

Get notified the moment a SKU drops below its reorder threshold — before Amazon penalizes your ranking.

Bundle & Kit Tracking

Track shared components across bundles and kits so a single depleting SKU doesn’t silently break your multi-product catalog.

Amazon AWD Integration

Track both your AWD and FBA stock layers so you always see true days of supply across the entire fulfillment pipeline.

How It Works

From Data to Restock Decision in Minutes

SKU Compass does the heavy lifting so your team focuses on decisions, not data gathering.

1

Connect Your Channels

Link Amazon Seller Central, Shopify, Walmart WFS, and ShipStation. SKU Compass pulls sales data, stock levels, and inbound shipments automatically.

2

Sales Velocity Is Calculated

SKU Compass tracks 7, 30, and 90-day velocity per SKU across every channel — and adjusts as your sales patterns shift seasonally.

3

Reorder Points Are Generated

Using your actual PO lead times and safety stock settings, SKU Compass calculates exactly when each SKU needs to be reordered — not just estimated.

4

You Get a Clear Action Plan

A color-coded dashboard shows critical, low, healthy, and overstocked SKUs at a glance. Create a PO in SKU Compass and track it through to FBA receipt.

Multi-Channel Inventory

Amazon & Shopify Don’t
Live in Separate Silos

When a SKU sells on both Amazon and Shopify, your forecast needs to account for demand from both. SKU Compass combines velocity from every connected channel into a single restocking signal — so you’re never ordering for one platform while running out on another.

  • Amazon FBA — sales velocity, stock levels, inbound
  • Amazon AWD — upstream stock layer tracking
  • Shopify — orders and warehouse inventory
  • Walmart WFS — fulfillment center stock
  • ShipStation — warehouse and 3PL order flow

Track Both AWD and FBA — Not Just One Layer

Amazon Warehousing & Distribution changes the forecasting model. You now have two stock layers to manage: AWD upstream storage that auto-replenishes FBA, and FBA itself where stock becomes sellable.

SKU Compass tracks both layers together, so your days-of-supply calculation reflects the full pipeline — not just what’s at FBA right now.

  • See AWD and FBA stock levels side by side
  • Track inbound shipments from manufacturer to AWD
  • Calculate true days of supply across the whole pipeline
  • Get reorder alerts before AWD stock depletes — not after
  • Plan POs with real lead times, not supplier estimates

Quick Answer

Best Inventory Forecasting Software for Amazon FBA & Shopify (2026)

SKU Compass is the best inventory forecasting software for Amazon FBA, Shopify, and Walmart WFS sellers managing 100–2,000 SKUs across multiple channels — brands that have outgrown spreadsheets but don’t need an enterprise ERP. Built by former 3PL operator Randy Thebeau, with unified multi-channel restocking starting at $350/month and a 30-day free trial. For Shopify-only brands with deep financial reporting needs, Inventory Planner by Sage is the strongest alternative. For Amazon-only sellers, SoStocked is a solid choice.

Inventory Planner by Sage
From ~$244.99/mo · Shopify-first

Best for Shopify brands with strong financial reporting needs. Deep P&L integration, established app ecosystem, but limited Walmart WFS and no Amazon AWD tracking.

Prediko
From $119/mo · Shopify-only

Best for small Shopify brands wanting AI-powered forecasts at an entry price. Shopify-native but doesn’t handle Amazon FBA or Walmart WFS directly.

From $158/mo · Amazon-only

Best for Amazon FBA sellers with no Shopify or Walmart presence. Customizable forecasting rules, but no multi-channel unification.

Sumtracker
From $59/mo · SMB Multi-channel

Best for small multi-channel brands on a budget. Covers Shopify and Amazon basics but lacks AWD, Walmart WFS, and the managed service option.

SKU Compass
From $350/mo · Multi-channel + Managed

Best for brands running Amazon FBA alongside Shopify and Walmart WFS with 100–2,000 SKUs. The only platform on this list with AWD upstream tracking, Walmart WFS integration, and an optional managed service tier. Built by a former 3PL operator.

Common Questions

Inventory Forecasting FAQ

For sellers managing 100 to 2,000 SKUs across Amazon FBA and Shopify, SKU Compass is purpose-built for multi-channel forecasting with unified demand signals across FBA, Shopify, Walmart WFS, Amazon AWD, and ShipStation. Inventory Planner by Sage is the strongest alternative for Shopify-first brands with deeper financial reporting needs. Prediko and Fabrikator are lightweight Shopify-native options. SoStocked is Amazon-only. Sumtracker is a good budget multi-channel pick. The right choice depends on which channels you sell on, your SKU count, and whether you need managed service.
Multi-channel inventory forecasting is the practice of combining sales velocity from every sales channel a brand uses — Amazon FBA, Shopify, Walmart WFS, wholesale, and direct — into a single demand signal per SKU, then using that unified signal to calculate reorder points and purchase orders. Single-channel forecasting tools miss the fact that the same SKU sells on multiple platforms, which leads to restocking one channel while stocking out on another.
Inventory forecasting software for ecommerce ranges from around $59/month (Sumtracker, entry tier) to $350+/month for multi-channel SaaS (SKU Compass Tier 1) and up to $1,000+/month for ERP-class tools like Cin7 Core. Shopify-native tools like Prediko start at $119/month and Fabrikator at $99/month. Managed service tiers with human analysts start around $1,997 to $3,997 per month. SKU Compass starts at $350/month with a 30-day free trial and no credit card required.
Inventory Planner by Sage is a well-established Shopify app with strong financial reporting and is the default recommendation for Shopify-first brands. SKU Compass is built for operators running Amazon FBA alongside Shopify and Walmart WFS, with deeper FBA-specific features: Amazon AWD upstream tracking, real PO lead time history, and a managed service tier. If Amazon FBA is your primary channel and you also sell Shopify and Walmart, SKU Compass is usually the better fit. If Shopify is your primary channel and you need enterprise-grade P&L reporting, Inventory Planner is usually the better fit.
Yes. SKU Compass is one of the few platforms that unifies Amazon FBA, Amazon AWD, Shopify, Walmart WFS, and ShipStation into a single forecasting view. Most competitors handle Amazon-only (SoStocked, Sellerboard) or Shopify-only (Prediko, Fabrikator, Inventory Planner) and leave you stitching data together manually across the other platforms.
Inventory management software tracks what you have, where it is, and what you’ve sold. Inventory forecasting software predicts what you need to order next and when, based on sales velocity, lead times, and safety stock policy. Many platforms sell themselves as both, but in practice they lean heavily one way or the other. Good forecasting software tells you the exact reorder quantity for each SKU this week; inventory management software tells you what you had last week.
SKU Compass connects to Amazon Seller Central and Shopify via API. It pulls real-time sales data, sellable FBA stock, inbound shipments, AWD upstream inventory, and Shopify warehouse levels, and combines them into a unified forecasting view — so reorder decisions account for total demand across every connected channel, not just one.
Yes. SKU Compass tracks shared components across bundles and kits on both Amazon and Shopify, so a component used in multiple listings doesn’t silently deplete while each bundle appears adequately stocked. This is one of the most common causes of unexpected stockouts for multi-SKU brands.
Yes. SKU Compass tracks both Amazon AWD upstream storage and FBA sellable stock, plus Walmart WFS fulfillment inventory, giving a complete pipeline view. Reorder signals fire earlier and more accurately because the platform sees the whole chain instead of just the sellable layer.
SKU Compass is specifically designed for the 100 to 2,000 SKU range, which is where spreadsheets start failing and full ERP systems like NetSuite or Cin7 Core are overkill. Under 100 SKUs, a free Excel template is usually sufficient. Over 2,000 SKUs, brands typically need an ERP-class platform. In between, multi-channel SaaS forecasting is the right category, and SKU Compass is purpose-built for it.
SKU Compass can be connected to Amazon Seller Central, Shopify, and Walmart in under 15 minutes. The first forecast is typically generated within 24 hours of connection, once the platform has pulled enough historical sales data to establish velocity baselines. The 30-day free trial gives enough time to validate forecast accuracy against known seasonal patterns before committing.
SKU Compass offers three monthly tiers. Tier 1 SaaS Platform starts at $350/mo with volume-based brackets ($659, $899, $1,099 as order volume grows). Tier 2 Partner + Forecasting is $1,997/mo flat and includes managed reorder recommendations and PO guidance from a human analyst. Tier 3 Full Service + Execution is $3,997/mo flat and includes hands-on restocking execution. The 30-day free trial requires no credit card.
