Scenarios Every saved plan, priced and side by side

The Home screen: saved plans as scenario cards, each with its projected units and revenue by year, and the ten sale events of the plan folded into a single row that opens on a click - 122,668 units and $2.1M of them. FY27 Base is marked active.

What's inside

The whole planning workflow, one app

Everything ships in a single Windows installer: the forecasting stack, the BI layer, the grids. Nothing to configure, nothing to host.

Forecasts you can trust

Statistics, gradient boosting and the Chronos-2 foundation model, blended into one ensemble and scored only on weeks they never saw - with your supplier lead time built into the test.

Disaggregation that holds up

Push an approved forecast down through channel, category, style, size and store. Pin a share, type over a cell, and the rest re-bases around it.

Purchasing that knows your constraints

Lead times, MOQs and target weeks of supply are real inputs. Warehouse-aware, so it moves stock you already own before it buys more.

From plan to financial impact

Set revenue targets in dollars and the plan solves back to them. Plan discounts and read margin, not units alone.

Built by planners, not consultants

Starts from the Excel workbook you already have, and exports back to it. No integration project, no APIs to wire up.

Automate it, then report on it

A CLI and a local HTTP API drive the whole workflow headlessly, so an agent can run your weekly cycle end to end.

How it works

Six steps from history to purchase orders

Each step hands the next one a reviewed number. Nothing leaves the app until you've signed off on it.

    Configure models, run, compare

  4. Step 04

    Forecast results

    Review and adjust the topline

  5. Step 05

    Disaggregate

    Edit the mix down the hierarchy

  6. Step 06

    Purchase

    Store splits, transfers and buy plan

Inside the app

Four screens most forecasting tools don't have

Accuracy scored on unseen weeks, a pivot that ships in the box, shares split the way you buy, and a buy plan that colours every decision.

Three accuracy leaderboards for the Ecom channel - short, medium and long horizon - each ranking seven models on score, SMAPE, MAPE, WAPE, bias in percent and in units per month, and RMSE. Chronos2 leads the short horizon at 16.3% WAPE against a seasonal naive's 22.4%; over the year XGBoost leads and the seasonal naive is last at 46.3%. The ensemble blend behind each horizon is named above its table.

Ecom, next quarter: Chronos2 at 16.3% error against a seasonal naive's 22.4% - and a different model wins the year. That is the argument for scoring every horizon instead of picking a favourite.

Backtest validation: actual demand as a dark slate reference line, with two model traces stitched across every rolling origin from 2019 to 2026. The other models stay in the legend, greyed. Dashed vertical lines mark where each window's history was cut.

Every model scored on weeks it never saw. Promotional lift is layered onto the published plan separately, so the spikes in Actual sit above every model trace here.

The built-in BI dashboard: an Excel-style free-form pivot with a field list and drop zones for Filters, Rows, Columns and Values. Two saved plans, FY27 Base and FY27 Upside, sit one per row with their forecast months side by side, and the chart above shows the pair diverging.

Drag Scenario into Rows and two plans sit one per line, month by month. Runs in-process on your own machine, and exports straight to Excel.

The shares editor: menswear categories as rows, with each month's share of the division across history and forecast. Ribbed Crew Sweater holds around half the division and climbs during Black Friday, while Relaxed Bodysuit gives share back over the same weeks. Sale periods sit in their own columns beside the months.

Every level gets its own share of its parent, seeded from history and editable in place. Sale periods keep their own columns, not smeared across the month.

The purchasing inventory projection: a week-by-week walk-through of opening stock, inbound, buys, transfers and demand down to unmet demand, ending units and weeks of supply, shown for the total and for a single style beneath it. Buys land on their supplier's lead time rather than all at once, weeks below the cover target are highlighted in amber, and any demand the buy could not cover in time is called out in its own row.

Approved forecasts become buy quantities per vendor and week, walked forward from opening stock. Amber where cover falls under target, red where stock runs out.

FAQ

Common questions

What do I get after purchasing?

Immediately after checkout you land on a page with your personal download link for the latest PlanCore-Setup.exe, plus install instructions. You'll also get a Stripe receipt by email, and I'll follow up to schedule your setup call.

Is the installer safe? Windows warned me about downloads before.

The installer is digitally code-signed, so Windows can verify the publisher before running it, and each release ships with a SHA-256 checksum you can verify yourself. It's a large download (~1 GB) because the entire forecasting stack is bundled - nothing is fetched at runtime.

Does my data go to the cloud?

No. PlanCore is fully offline after installation. Forecasting runs on your machine, your workbooks stay in your local app data folder, and the app never phones home - there is no telemetry of any kind.

How do updates work?

When a new version ships you'll get an email with the same permanent download link. Run the new installer and it upgrades in place - your scenarios, workbooks, and settings are never touched.

What are the system requirements?

Windows 10/11, 64-bit. 8 GB RAM minimum (16 GB recommended for AI forecasting on larger datasets). No graphics card required: the forecasting stack ships CPU-only and runs on an ordinary work laptop.

If the machine does have a recent NVIDIA card, the installer offers to enable GPU acceleration for forecasting - it's a tick box during setup, and it downloads about 2.4 GB the one time. It's only offered for cards new enough to actually be faster, and if the card turns out not to work the installer puts the CPU version back on its own.

Can I try it before buying?

Get in touch - I'm happy to do a live demo on a screen share with your kind of data, and walk through whether it fits your workflow before you spend anything.
