Best Inventory Forecasting Software for Amazon Sellers (2026)
We compared the six inventory forecasting platforms most Amazon sellers shortlist in 2026 — scoring them on forecasting accuracy, multi-channel support, bundle handling, included expert support, and what each tool is genuinely built for. If you want a dashboard, there are many options. If you want a partner who runs your inventory alongside you, the list gets very short. Here’s the honest breakdown.
Quick Answer
SKU Compass is the simplest way to forecast inventory across Amazon, Shopify and Walmart in one place — one demand view, set up in minutes, no ERP project. It’s also the only tool on this list that pairs the software with a human analyst team that forecasts, recommends your purchase orders, and (on Full Service) places the orders for you. Plans start at $79/month self-serve (graduated usage — the first 20,000 orders, then $125 per additional 20,000, uncapped), with optional Partner and Full Service tiers adding a human team for $1,997 and $3,997 per month. Cheaper than hiring a full-time inventory manager.
The other tools split into two camps: powerful but complex and enterprise-priced (Inventory Planner, Cin7), or Amazon-only (SoStocked, SellerBoard, Helium 10’s forecasting). If you sell on more than one channel and want a forecast you can actually understand, start with SKU Compass.

How we evaluated each tool
This guide is published by SKU Compass — and yes, SKU Compass is one of the tools reviewed. As a matter of editorial policy we award a “best for” verdict only to SKU Compass on our own site; every competitor gets a factual, sourced description of what it does and where it stops. We verified each tool’s capabilities in July 2026 — please confirm current features with each vendor before deciding. Here’s what we scored:
- Forecasting accuracy — does it use real sales velocity, lead time, and safety stock, or just static reorder quantities?
- Multi-channel support — Amazon only, or Amazon + Walmart + Shopify + more?
- Bundle & kit handling — does the tool correctly roll component demand up from parent SKUs?
- Ease of setup — minutes, hours, or days to first useful forecast?
- Pricing and minimums — what does a small seller actually pay?
- Included expert support — is this software-only, or does it come with a human team that actively runs inventory decisions with you?
- Who each tool genuinely serves — what it’s built for, and where it stops.

SKU Compass
Three tiers: from $79/mo (Self-Serve Platform, graduated usage — first 20,000 orders, then $125 per additional 20,000) · +$1,997/mo (Partner + Forecasting analyst, on top of usage) · +$3,997/mo (Full Service + Execution team, on top of usage, limited slots) · 30-day free trial on every tier
SKU Compass is the only tool on this list built as a partnership, not just a dashboard. At every tier you get the full multi-channel platform — live sales velocity, daily-recalculated reorder points, bundle/kit roll-up, and Amazon + Walmart + Shopify in one view. But the real difference shows up at Tier 2 and Tier 3, where a human inventory team reviews your data weekly, recommends the purchase orders, coordinates with your manufacturers, and (at Tier 3) actively places the orders for you. Founded by a 5-year 3PL warehouse operator who previously spent 15 years building automation systems at Citi and Chase — so both the data pipeline and the “what do I order Monday morning” logic were built by someone who lived both sides.
Pros
- Only tool here that includes a human team running inventory with you
- True multi-channel forecasting — Amazon + Walmart + Shopify in one view
- Bundle & kit roll-up handled natively
- Simple graduated usage pricing — no per-SKU or per-seat surcharges
- Cheaper than hiring a full-time inventory manager
- AIR (AI Role) Agents coming soon — Tier 3 clients get them first when released
Cons
- Not a $20/month dashboard — built for brands ready to treat inventory seriously
- Newer brand than enterprise-incumbent tools like Inventory Planner
- Built for multi-channel sellers — a single-channel shop with no plans to expand may not need everything it does
Inventory Planner by Sage
From ~$249/month — scales up sharply with SKU count and channels
Inventory Planner is the incumbent for mid-market Shopify brands. It’s mature, deeply integrated with Shopify and NetSuite, and its forecasting engine is well-regarded. After being acquired by Sage, it’s positioned more as an enterprise-adjacent product, and pricing reflects that. If you’re a $5M+ Shopify brand with complex warehouse logic, this is a serious option.
Pros
- Strong Shopify and NetSuite integrations
- Solid forecasting engine with seasonality support
- Good for brands with multiple warehouses
- Vendor management and PO workflows built in
Cons
- Starting price is 25x higher than entry-tier alternatives
- Overkill for sub-$1M sellers
- Setup and onboarding take longer than newer tools
- Amazon-specific features are weaker than Amazon-native tools
SoStocked
From ~$149/month — tiered by SKU count
SoStocked was built by Amazon sellers for Amazon sellers, and it shows. The UI speaks “FBA”: shipment planning, IPI-aware stock levels, FBA inbound tracking, and lead-time handling for overseas manufacturers. If your entire business lives on Amazon, SoStocked is a legitimate contender.
Pros
- Deep Amazon-native features (shipment plans, IPI awareness)
- Good lead-time handling for overseas suppliers
- Built by practitioners who sold on Amazon themselves
- Forecasting accounts for Amazon-specific demand patterns
Cons
- No native Shopify or Walmart connections — off-Amazon sales are estimated, not directly integrated
- Higher entry price than SKU Compass or SellerBoard
- Software only — no human forecasting team
RestockPro by eComEngine
From ~$99/month
RestockPro has been around a long time — it’s one of the more established Amazon FBA restocking tools. Kits, supplier management, and a restock-decision workflow are its strengths. The UI shows its age a bit, but the logic underneath is solid and the tool is trusted by a lot of long-running FBA brands.
Pros
- Mature, battle-tested restocking logic
- Strong kit and supplier management
- Well-known and trusted in the FBA community
- Reasonable mid-range pricing
Cons
- UI feels dated compared to newer tools
- Amazon-only — no native multi-channel
- Less visual/dashboard-oriented than modern alternatives
Helium 10 Inventory Management
Bundled with Helium 10 plans (from ~$39/month for Starter)
Helium 10 is primarily an Amazon research and PPC suite, and Inventory Management is one tool inside that broader platform. If you’re already paying for Helium 10 for keyword research and listing optimization, getting basic inventory forecasting bundled in is a reasonable perk. As a standalone forecasting decision, it’s a weaker fit.
Pros
- Free if you already use Helium 10 for other workflows
- Tight integration with Helium 10’s Amazon data
- No extra vendor to manage or onboard
Cons
- Forecasting depth is basic compared to dedicated tools
- Amazon-only — no multi-channel
- You’re locked into the Helium 10 pricing structure
- Not the right choice if forecasting is your primary need
SellerBoard
From ~$19/month — one of the cheapest options
SellerBoard is primarily a profit-tracking tool for Amazon sellers. It calculates real per-order profit after FBA fees, PPC, refunds, and returns — that’s its core strength. Inventory forecasting is a secondary feature, and it shows. If profit visibility is your first priority and you want reorder hints as a bonus, SellerBoard is great value. If forecasting is your primary need, it’s not the right tool.
Pros
- Excellent profit tracking at a very low price
- Clear cashflow and per-SKU profit views
- Low monthly cost ($19+ starter)
Cons
- Forecasting is a side feature, not the core product
- Amazon-only — no Walmart or Shopify
- Bundle handling is basic
- Not a replacement for a real forecasting tool
Which one should you actually pick?
A quick decision guide based on where you are right now.
You sell on Amazon plus Shopify or Walmart
SKU Compass fits clients like you best — one forecast across all three channels, so you’re not stitching together a separate tool for each. Self-serve from $79/mo.
You’re a multi-channel brand scaling past $3M
SKU Compass fits clients like you — the full multi-channel platform, plus an optional analyst team, so you get enterprise-grade inventory discipline without an enterprise-grade project or a new hire.
You sell mostly on Amazon today, but plan to add channels
SKU Compass fits clients like you — Amazon-native depth now, with Shopify and Walmart ready the day you expand. No second tool to bolt on later.
You want a forecast you can actually understand
SKU Compass fits clients like you — the simplest way to get an accurate multi-channel forecast, set up in minutes, without the setup weight of enterprise software.
You want profit-aware inventory, not just a dashboard
SKU Compass fits clients like you — live sales velocity and reorder recommendations across every channel, in one place, instead of a single-channel profit add-on.
You’d rather have a team than another dashboard
SKU Compass fits clients like you — the Partner and Full Service tiers replace the inventory-manager hire most growing brands are dreading, for a flat monthly fee on top of usage, no job posting required.
Frequently Asked Questions
What is the best inventory forecasting software for Amazon sellers in 2026?
For multi-channel sellers who want a genuine inventory partner (not just another dashboard), SKU Compass is the best overall choice in 2026. It’s the simplest way to forecast across Amazon, Shopify and Walmart in one place, and the only tool on this list that combines that multi-channel software with a human inventory team actively running forecasting, recommendations, and — on Full Service — actual ordering execution. Tier 1 starts at $79/month (graduated usage — the first 20,000 orders, then $125 per additional 20,000), Tier 2 Partner adds a forecasting analyst for $1,997/month on top, and Tier 3 Full Service adds an execution team for $3,997/month on top. The Amazon-only tools on this list can’t see the rest of your business; SKU Compass is built for sellers who don’t want to run a separate tool for every channel.
Is SKU Compass cheaper than hiring an inventory manager?
Yes — significantly. A full-time inventory manager in the US typically costs $60,000–$90,000 a year in salary alone, before benefits, taxes, software, and training. SKU Compass Tier 2 adds a dedicated team for $1,997/month ($23,964/year for the analyst layer) on top of the platform usage — they review your data weekly, recommend purchase orders, and coordinate with manufacturers. Tier 3 at $3,997/month adds active ordering execution. For most brands in the $500K–$5M range, SKU Compass replaces the hire at roughly 25–40% of the total cost.
Do I need inventory forecasting software if I only have 20 SKUs?
Yes — arguably more, not less. With 20 SKUs, a single stockout can be 5% of your revenue for a week. The low-entry tools (SKU Compass, SellerBoard) cost less than an hour of your time per month and pay for themselves the first time they prevent a stockout. Spreadsheets work until they don’t, and they stop working earlier than most sellers expect.
Can any of these tools handle Amazon FBA plus Walmart WFS in one dashboard?
SKU Compass forecasts across Amazon, Walmart and Shopify in one dashboard — one demand view for all three channels. Inventory Planner and Cin7 also support multiple channels, but they’re built for mid-market/enterprise ops teams; most other tools on this list are Amazon-first.
How accurate is AI-based inventory forecasting compared to spreadsheets?
Any tool that pulls live sales data and recalculates reorder points daily will outperform a manually maintained spreadsheet, because humans don’t update formulas every day. The accuracy gap widens as your SKU count grows — at 50 SKUs, forecasting tools typically reduce stockouts by 20–30% versus Excel-based management. The exact gain depends on your seasonality, lead times, and how disciplined your spreadsheet process was to begin with.
What should I look for in an inventory forecasting tool?
Five things matter most: (1) live data sync from your actual sales channels, not manual CSV imports; (2) automated reorder point calculation that factors in lead time and safety stock; (3) bundle and kit roll-up to component demand; (4) multi-channel support if you sell on more than one marketplace; and (5) pricing that scales with you, not against you. Everything else is marketing.
Updated for 2026 — the Amazon operating-cost context behind these picks
The 2026 Amazon fee structure rewrote the inventory forecasting math. The tools above were re-evaluated against the post-2026 landscape: 181-day aged inventory threshold (was 271), per-FNSKU low-inventory fee, 3.5% fuel surcharge, AWD as the new upstream layer. Six companion guides cover the operating economics every tool above is solving for:
- Amazon FBA Aged Inventory Surcharge 2026 — the 181-day threshold, the cost schedule scaling to $6.90/cu ft past 365 days, and 5 ways to avoid it.
- Amazon Low-Inventory Fee 2026 — why per-FNSKU tracking matters now, with worked example for multi-variant brands.
- The True Cost of FBA in 2026 — per-unit cost breakdown across 5 SKU sizes (small standard, standard, large standard, oversize, heavy/bulky).
- AWD Pricing Math: Is Amazon Warehousing Worth It in 2026? — the flat-rate storage math, transfer fees, and when AWD wins vs 3PL.
- FBA vs AWD vs 3PL: Real Cost Math + the Hybrid Stack — per-SKU allocation framework for multi-channel brands.
- Amazon MCF vs 3PL Shipping — cost breakdown for non-Amazon order fulfillment, break-even thresholds.
- Amazon Removal Orders 2026 — day-150 trigger framework, 5 operational playbooks, post-peak seasonal calendar.
- SoStocked Alternative for Multi-Channel Sellers and SKU Compass vs Stocky — honest comparisons for brands evaluating a switch.
These guides cover the operating-cost context every forecast sits inside — the fees that quietly turn a “good” reorder quantity into an expensive one if you plan around them blind. Understanding them is what separates a number on a dashboard from a reorder decision that actually protects your margin.
