SKU Compass vs Inventory Planner: Honest Comparison for Multi-Channel Sellers
Inventory Planner by Sage is the default recommendation for Shopify-first brands. SKU Compass is purpose-built for sellers running Amazon FBA alongside Shopify and Walmart WFS. Which one you should pick depends on one thing: your channel mix.
Quick Answer
Pick Inventory Planner if: Shopify is your primary channel, you value deep P&L reporting, and Amazon/Walmart are secondary or not in play. Inventory Planner has 10+ years of Shopify-first polish and Sage’s financial reporting depth.
Pick SKU Compass if: Amazon FBA is a primary channel (or you sell on Walmart WFS), you need Amazon AWD upstream tracking, bundle/kit component forecasting, or a managed-service tier where a human analyst reviews your restock plan weekly.
Both tools handle multi-channel. The difference is which channel they’re optimized for — and whether you need analyst help on top of software.

Where Inventory Planner wins
Shopify-first brands
If Shopify is your primary channel — you’ve been building a DTC brand there for 3+ years, email list and ads funnel to Shopify, Amazon is either absent or a secondary overflow — Inventory Planner fits more naturally. The integration is deeper, the UI assumes Shopify logic, and the ecosystem of related apps is richer.
Deep financial / P&L reporting
Inventory Planner is owned by Sage (the enterprise accounting company), and the financial reporting depth reflects that. If your CFO or agency wants weekly inventory valuation reports with full P&L tie-in, margin analysis by SKU, and accounting-grade outputs, Inventory Planner has more built in.
Established app ecosystem
Inventory Planner has been around since ~2013. It integrates with 3PLs, ERPs, and accounting tools that a newer platform might not support yet. If you’re already in a complex stack that has a “works with Inventory Planner” integration you’d lose, that matters.
Where SKU Compass wins
Multi-channel sellers with Amazon FBA as a primary
SKU Compass was built by a former 3PL operator who ran Amazon FBA inventory every Monday for five years. Amazon-specific features — AWD upstream tracking, per-FNSKU reorder points (matching Amazon’s 2026 low-inventory fee structure), FBA receiving time in lead-time math, Walmart WFS integration — are first-class, not afterthoughts. Inventory Planner handles Amazon; SKU Compass was built for it.
Per-SKU, per-channel velocity
The same SKU sells at different rates on Amazon vs Shopify vs Walmart WFS. SKU Compass tracks those velocities separately and calculates separate reorder points per fulfillment location. This is the per-SKU per-channel framework — the operator lane SKU Compass owns. Tools that blend channel velocities into one number (most do) lose the ability to allocate properly.
Managed service tier
Inventory Planner is software only. SKU Compass offers three tiers:
- Tier 1 ($350/mo+): software only — comparable to Inventory Planner
- Tier 2 ($1,997/mo): software + human analyst reviews your restock plan weekly
- Tier 3 ($3,997/mo): software + analyst + active PO execution
For brands who’d otherwise hire a $75K inventory manager, Tier 2 is the alternative. No equivalent exists in the Inventory Planner world.
Amazon AWD + 2026 fee awareness
Amazon’s 181-day aged inventory threshold, the 3.5% fuel surcharge, and the per-FNSKU low-inventory fee all changed FBA economics in 2026. SKU Compass’s reorder math and AWD buffering logic are built around these. See our 2026 FBA forecasting guide. Inventory Planner handles Amazon but isn’t specifically optimized for these changes.
Decision framework: answer these four questions
Pick Inventory Planner if…
- Shopify is your primary channel (60%+ of revenue)
- You have a strong accounting/finance workflow and want inventory P&L depth
- Amazon is absent or secondary
- You don’t need human analyst support — software is enough
- You’re in a stack with existing Inventory Planner integrations
Pick SKU Compass if…
- Amazon FBA is a primary channel (or you’re 50/50 multi-channel)
- You sell on Walmart WFS or use Amazon AWD
- You need per-FNSKU reorder points (new 2026 requirement)
- You want optional managed service — a human analyst reviewing your plan weekly
- Bundle/kit component tracking matters for your catalog
- You want the operator-voice support (Randy built the software from a 3PL’s floor)
When the honest answer is “try both”
Both tools have 14–30 day free trials. If you’re genuinely unsure — maybe you sell 50% on Shopify and 50% on Amazon FBA, no physical stores, 200–500 SKUs — spin up both in parallel for two weeks. Connect the same channels. Run the same forecasts. See which dashboard you actually open every Monday. The one you actually use is the one you should buy. Don’t over-engineer the decision.
What they have in common (fair is fair)
Both tools:
- Connect to Amazon Seller Central, Shopify, and other major channels via API
- Calculate reorder points based on sales velocity and lead times
- Track inbound stock and open POs
- Handle bundles and kits
- Generate purchase order recommendations
- Offer a free trial
- Have real customer reviews on Capterra / G2 / Shopify App Store
Neither is a bad tool. This is a “right tool for your situation” question, not a “which one is better” question.
Frequently asked questions
Is SKU Compass cheaper than Inventory Planner?
Entry-tier pricing is similar — Inventory Planner starts around $244.99/mo, SKU Compass starts at $350/mo. Both use volume-based pricing that scales with order count. At higher volumes, pricing converges. The bigger cost difference is the managed service tier: SKU Compass Tier 2 ($1,997/mo) bundles software + human analyst; Inventory Planner doesn’t offer this — you’d hire an agency or inventory manager separately, which typically costs more.
Can Inventory Planner handle Amazon FBA?
Yes, Inventory Planner integrates with Amazon Seller Central and handles FBA forecasting at the parent-ASIN level. However, it does not track Amazon AWD (upstream warehousing) as a distinct inventory layer, and its reorder math is not specifically built around Amazon’s 2026 fee changes (181-day aged inventory threshold, per-FNSKU low-inventory fee). For FBA-primary sellers, SKU Compass is usually a better fit.
Does SKU Compass work as well as Inventory Planner for Shopify-only brands?
SKU Compass handles Shopify well, but Inventory Planner has deeper Shopify-native polish — the UI assumes Shopify logic, it integrates with more Shopify apps, and the Sage financial reporting backend is stronger. For a pure Shopify D2C brand with no Amazon presence, Inventory Planner is usually the better fit. If Amazon is in play at any meaningful level, the calculus flips.
What is SKU Compass’s managed service tier and does Inventory Planner offer something similar?
SKU Compass Tier 2 ($1,997/mo) includes everything in the software tier plus a human analyst who reviews your data weekly, produces restock recommendations, and provides manufacturer guidance. Tier 3 ($3,997/mo) adds active PO execution. Inventory Planner is software-only — there is no equivalent built-in service tier. To get similar support with Inventory Planner, you’d hire an inventory management agency separately, typically $2K–$5K/mo.
Can I migrate from Inventory Planner to SKU Compass (or vice versa)?
Yes. Both tools import data directly from your sales channels via API, so migration is mostly about reconnecting Seller Central, Shopify, and Walmart accounts — not transferring historical data between platforms. The switch takes 15–30 minutes. Plan for a 2-week overlap where both run in parallel to validate the new forecasts against your existing workflow.
Which one has a longer free trial?
SKU Compass offers a 30-day free trial with no credit card required. Inventory Planner’s trial length varies (typically 14 days) and may require a sales call to activate. For a genuine side-by-side evaluation, SKU Compass gives you more time without commitment.
Which tool do Amazon aggregators and large FBA brands use?
Mixed. Aggregators with large, diverse portfolios often run enterprise tools (NetSuite, Cin7 Core) for accounting-level consolidation. For operator-level forecasting, both Inventory Planner and SKU Compass appear in the ecosystem, with SKU Compass more common among Amazon-primary brands and Inventory Planner more common among Shopify-primary brands. There is no single dominant tool at the brand level.
