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 decision-first demand-planning platform for $10–50M consumable CPG brands — with scenario consequence previews, a retail-deal pipeline, and an overnight AI agent, all on top of the same forecasting engine.
The short answer
No tool wins for everyone. Here's the honest split.
Consumable CPG brands ($10–50M) who want to test big moves before committing capital, plan retail launches against real supply, and have every SKU checked overnight — on a simple, predictable flat price.
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 pricing that scales with their revenue on an annual contract.
Feature-by-feature
| Capability | Planster | Inventory Planner |
|---|---|---|
| Purpose-built for $10–50M consumable CPG | Yes — the entire product targets this ICP | Generalist retail (apparel, beauty, furniture, sporting goods); not CPG-specific |
| Scenario planning with consequence preview | Sandbox what-ifs; see PO + capital impact before committing (~$292K); promote with version history + un-promote | 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 scan of every SKU/PO/channel → ranked morning digest email with draft POs attached (draft-only, you approve) | Sage Copilot in-app advisor flags priority replenishments and late POs; human-in-the-loop, but no scheduled overnight digest |
| Onboarding time | Fast — most brands run their first what-if on day one | Reported ~5–6 weeks guided onboarding (97% success claim) |
| Pricing model | Flat ~$1,000/mo — one predictable number that doesn't change when you have a good month | Priced against your revenue: the more you sell, the more you pay — on an annual contract, with real numbers hidden behind a sales quote (only the $119.99/mo Shopify-only entry tier is public). "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) — plus native accounting/ERP: Zoho and Luminous live today, with QuickBooks, Xero, NetSuite, and Sage 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 what-if through your real ordering engine and shows the consequence — which POs move and how much capital the change pulls forward — before you say yes. Most planning tools tell you what to reorder; Planster tells you what a whole scenario commits.
Plan the retail launch, not just the reorder
Planster's Pipeline treats retail deals as living demand: a deal overlays your plan at full volume and does the risk-buy math — the order-by date to hit the launch, and the capital at risk if it falls through. That founder-level "do I buy before the buyer decides?" question is one a reorder tool never answers.
The checking happens overnight — the decision stays yours
Every night the Planster Agent checks every SKU, PO, and channel and emails a ranked morning digest with draft POs attached. You change what you want changed and approve in the app. It cannot promote, approve, or send on its own, and no setting changes that.
Pricing
Flat ~$1,000/month. One predictable number, no implementation fee, and it doesn't go up because you had a good quarter.
Priced as a function of your revenue — the more you sell, the more you pay, locked into an annual contract. Only the $119.99/month Shopify-only entry tier is public; every real tier is hidden behind a sales quote. It's no surprise "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 small Shopify-only brand where the $119.99/mo entry tier fits better than a flat mid-market price.
Common questions
Is Planster a full Inventory Planner replacement?
For $10–50M consumable CPG brands, 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 is a flat ~$1,000/month with no implementation fee — the price is the same whether you have a slow month or a record one. Inventory Planner (by Sage) prices against your revenue on annual contracts: only its $119.99/month Shopify-only entry tier is public, and every higher tier is quote-gated and climbs as you grow.
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).
