Planster vs Inventory Planner
Inventory Planner (now "by Sage") is a mature, established forecasting-and-reorder platform used by 2,600+ brands. Planster is a demand and supply planning platform for $50–500M consumable CPG brands — with scenario planning that shows what a change commits, retail deal planning, and overnight checks with drafted purchase orders, all built on the same per-SKU forecast.

The short answer
No tool wins for everyone. Here's the honest split.
Consumable CPG brands and manufacturers ($50–500M) who want to test big moves before committing capital, plan retail launches against real supply, and have every SKU checked overnight — on published tiers that don't rise with their sales.
Established multi-channel retailers (apparel, beauty, furniture) who want a mature, broad platform with a large report library and Open-to-Buy budgeting, and don't mind a quoted price that scales with the volume of inventory they manage.
Feature-by-feature
| Capability | Planster | Inventory Planner |
|---|---|---|
| Purpose-built for $50–500M consumable CPG | Yes — built for this segment | Generalist retail (apparel, beauty, furniture, sporting goods); not CPG-specific |
| Scenario planning with a cost preview | Model scenarios; see the POs and cash a change commits (~$292K) before approving it; version history and roll-back | Open-to-Buy budgeting and reorder suggestions; no what-if sandbox, no capital-consequence preview, no versioning |
| Retail-deal pipeline → demand (risk-buy math) | Deals overlay the plan at full volume; tells you the order-by date and capital at risk if a deal falls through | Forecasts organic demand only; no retail-deal or sales-pipeline planning |
| AI agent | Overnight check of every SKU, PO and channel, then a ranked morning email with draft POs attached; your team approves | Sage Copilot in-app advisor flags priority replenishments and late POs; human-in-the-loop, but no scheduled overnight digest |
| Onboarding time | Days — most teams are planning within days of connecting their data | Reported ~5–6 weeks guided onboarding (97% success claim) |
| Pricing model | Plan $999/mo for the full app — published tiers priced by what you plan, so the price doesn't change when you have a good month | "Based on the volume of inventory you manage", with unlimited users. No tiers or prices are published; you request a quote (vendor pricing page, 2026-10-02). "Value for Money" is their lowest-rated dimension (4.4/5) |
| Integrations | 150+ integrations via Trackstar — WMS, 3PL, fulfillment, and every major sales channel (Shopify, Amazon, Walmart, TikTok, and more) — including NetSuite — plus native Sage 100, Zoho Analytics and Luminous connectors, with QuickBooks and Xero rolling out | 50+ integrations |
| Reporting & dashboards | Build any custom report you need — and the AI agent can draft report definitions for you and flag what needs attention | Large library of prebuilt reports, plus Open-to-Buy budgeting |
| Platform maturity & track record | Newer, focused; purpose-built for consumable CPG | More established — larger install base (2,600+ brands) and years of edge-case coverage |
| Third-party review ratings | Newer to market — actively building its review base | G2 4.5/5 (~39 reviews), Capterra 4.6/5 (~66 reviews) |
Where Planster pulls ahead
See what a decision costs before you commit
Planster's Master Plan runs every scenario through the same ordering calculation as your live plan and shows which POs move and how much cash the change pulls forward, before anyone approves it. Most planning tools tell you what to reorder; Planster also shows what a whole scenario commits.
Plan the retail launch, not just the reorder
Planster's Pipeline puts retail deals into the demand plan at full volume and calculates the order-by date to make the launch and the cash at risk if the deal falls through. Whether to buy before the buyer decides is a question a reorder tool does not answer.
Checks run overnight; decisions stay with your team
Every night Planster checks every SKU, PO and channel and emails a ranked morning digest with draft POs attached. Your team changes what it wants changed and approves in the app. It cannot approve a plan or an order, or send anything, on its own, and no setting changes that.
Pricing
Pilot $99/month, Plan $999/month, Produce $2,499/month. Published tiers priced by what you plan, no implementation fee, and the price doesn't go up because you had a good quarter.
Inventory Planner says its pricing "is based on the volume of inventory you manage", with unlimited users at no extra cost. It publishes no tiers or prices; every figure comes from a sales quote, so you can't compare it with Planster until you've been through a call. "Value for Money" is their lowest-rated dimension on G2 and Capterra (4.4/5).

When Inventory Planner is the better fit
No tool wins for everyone. Here's where Inventory Planner is the honest choice.
- You want a large library of prebuilt reports out of the box rather than building your own custom ones.
- You need the most mature, established platform with years of edge-case coverage and built-in Open-to-Buy budgeting.
- You are a retailer outside consumable CPG and want a broad forecasting-and-reorder platform with a long track record, and a quote-based price doesn't bother you.
Common questions
Is Planster a full Inventory Planner replacement?
For $50–500M consumable CPG brands and manufacturers, yes — Planster provides forecasting, multi-channel and multi-warehouse planning, reorder recommendations, S&OP, BOM/kitting, and integrations, plus scenario planning, a retail-deal pipeline, and an AI agent on top. Very large or non-CPG retailers may prefer Inventory Planner's broader, more mature feature set.
How much does Planster cost vs Inventory Planner?
Planster publishes three tiers — Pilot at $99/month, Plan at $999/month and Produce $2,499/month — with no implementation fee. Tiers are priced by what you plan, not by revenue, so the price is the same whether you have a slow month or a record one. Inventory Planner (by Sage) prices "based on the volume of inventory you manage" and publishes no tiers or prices, so its cost is a sales quote.

Does Inventory Planner have an AI agent like Planster?
Inventory Planner offers Sage Copilot, an in-app AI advisor that flags priority replenishments and late POs with a human in the loop. It is not a scheduled overnight agent — Planster's agent scans every SKU, PO, and channel overnight and emails a ranked morning digest with draft POs already written and waiting for your approval (draft-only).
