Everything in the platform
The forecasting engine, the purchasing math that runs on it, and the layers on top. 17 capabilities, one demand plan, and an agent that works the whole thing overnight.
The engine
One forecast across every channel, netted against what is on hand, on order, and already committed. Everything else runs on top of it.

Demand forecasting
Prophet, ETS, SARIMA, and linear regression, tested against each SKU’s own history. Planster picks the best fit and switches when the pattern changes. Seasonality per product. Stockout weeks excluded, so a week you couldn’t sell doesn’t teach the model you can’t sell.
Explore Demand forecastingExceptions
Set a tolerance per SKU. Planster tells you when one runs outside it, and by how much — while there’s still lead time to act.
Explore ExceptionsEvery number has a name on it
Edit any forecast cell by hand. Every one records who set it, when, and whether it was a person or the system. "Why is this 8,000" has an answer.
Explore Provenance
Multi-channel and multi-warehouse
DTC, Amazon, retail, and wholesale planned separately, then combined. Unlimited warehouses and 3PLs from one view, with demand split per warehouse — so you know what to order and where to send it.
Explore Multi-channel
Reorder recommendations
Reorder points and quantities calculated per SKU from real demand variability. Safety stock sized to the service level you actually want — 95% and 99% need very different buffers. Lead times, MOQs, and container quantities applied to the timing. Inventory position counted honestly: on hand, plus on order, minus committed. Overstock flagged before it turns into dead cash.
Explore Reorder recommendationsRetail planning
Doors × facings × velocity, tracked per retailer. Each one a real record — door count, rolling velocity, products carried, your contact. Per-store and last-year numbers sit alongside, so you can tell real growth from more doors.
Explore Retail planning
Purchase orders
Edit quantities, place purchase orders from Planster, and track inbound shipments by status all the way through delivery.
Explore Purchase ordersPromotions
Build a promotion as its own object — dates, the SKUs and warehouses it covers, the lift. It enters demand as a promotion, not a number someone typed into a cell.
Explore PromotionsSuppliers
Who they are, who you talk to, and the terms that govern ordering. Change a lead time from six weeks to nine and every order date that depends on it moves.
Explore SuppliersYour own numbers
A launch with no history, a line you’re discontinuing, a number the board already committed to. Set it by hand and keep it next to the forecast to see where the two disagree.

S&OP dashboard
Orders due this week, forecast exceptions, incoming shipments, overdue orders. Sales and operations read the same plan instead of arguing from two spreadsheets.
Explore S&OP dashboardBase plan and live plan
Keep a base plan alongside the live one actually driving orders, and see how far the working plan has moved.
Explore Base vs live plan
BOM and kitting
See which production runs are coming and what each consumes. Shared raw materials planned in one place — so you find out you’re short the same bottle for three SKUs before the run, not during.
Explore BOM and kitting
Data in and out
Warehouse data at 11pm, cart data at 7pm, forecasts at 7am. Export all DTC demand, all retail demand, or one retailer at a time. Credentials stored encrypted.
Explore Data in and outOn top of the engine
Same forecast, same data, same numbers. Three things you can do with it.

Master Plan
Sandbox a change as a scenario over live demand. Planster runs it through the real ordering engine first: which orders move, and how much capital it pulls forward. Promote with cell-level history, un-promote to restore exactly.
Explore Master Plan
Pipeline
Deals live in the plan, not someone’s inbox. They overlay at full volume, explode into the real retail shape, and show the week you have to order — plus what you’re out if the deal dies.
Explore Pipeline
Agents
Every SKU, order, and channel re-checked overnight. A short ranked email each morning with the orders already written. Ask it anything and the answer links to the screen that proves it.

Reporting is custom. There’s no report library.
You build the reports you need, and the agent can draft report definitions for you. What Planster does not have is a catalogue of prebuilt reports to pick from.
If a shelf of canned reports is what you are shopping for, some competitors have one. Inventory Planner is the obvious example, and that is a real reason to choose it.
What the agent can’t do
It reads everything you can see. It ranks what needs your attention. It writes the purchase orders. It answers questions with a link to the proof. That’s the list.
It cannot promote a plan. It cannot approve an order. It cannot send anything to a supplier. It cannot delete. There’s no setting that changes this, which means the worst case is a draft you delete.
