Demand planning for SKU-heavy operations

Decide what to order.
Defensibly. Every week.

Stocktimal takes your demand forecast, supplier lead times, current stock, and outstanding orders and proposes a purchase-order plan per SKU. It is not an ERP and it is not S&OP. It is the layer between your forecast and the order you actually place.

The problem

The reorder decision is where forecasts meet reality — and where most of it still happens in a spreadsheet.

You have a forecast. You have stock. You have a supplier with a lead time and a minimum order quantity. Somewhere between those facts and a purchase order, there is a judgement. We have watched that judgement land in three places.

  • Stockouts on the SKUs that matter

    A reorder slipped by a week because someone was on holiday, or the lead time quietly drifted, or the forecast changed and nobody recut the plan.

  • Cash parked on slow movers

    Safety stock that was set once and never revisited. Reorder quantities anchored to a round number from 2019.

  • Planning that lives in one head

    Decisions defensible in conversation, not in writing. Hard to hand over, hard to audit, hard to question.

How it works

A run, not a dashboard.

Stocktimal is organised around the ordering run: a unit of work that takes the current state, applies a parameter set, and returns a per-SKU schedule. Baselines, what-ifs, and approvals all sit on the same artefact.

  1. 01

    Bring your numbers in

    Upload current stock, outstanding purchase orders, and a demand forecast as CSV. Stocktimal stays out of the bookkeeping business — the ERP remains the source of truth.

  2. 02

    Configure once, override anywhere

    Group SKUs by how you actually plan them. Set fill-rate targets, lead times, holding and order costs at the group level; override per SKU where reality demands it.

  3. 03

    Run the engine

    A run takes the current state and proposes order quantities and timings per SKU. Try a what-if with a 10% demand bump or a tighter lead time — runs are first-class and sit alongside the baseline.

  4. 04

    Review, edit, export

    Inspect the trajectory behind every proposal. Tweak quantities inline. Approve, download the CSV, hand it to the ERP. Every run is reproducible from the exact inputs that produced it.

Reproducible by design. Every run pins the mapping version, the parameter set, and the override set it ran against. Approved orders carry stable ids that round-trip when you upload the next outstanding-orders snapshot.

Fit

Who Stocktimal is built for.

Probably a fit if

  • You run a catalogue with hundreds to low thousands of SKUs.
  • Your ERP holds stock and orders, but the reorder decision lives in a spreadsheet.
  • Lead times vary enough that a fixed reorder point overshoots or undershoots routinely.
  • You want the planning logic written down, versioned, and reproducible — not folklore.

Probably not the right tool if

  • Looking for an ERP, WMS, or full S&OP suite.
  • Want fully automated ordering with no human review step.
  • Need a multi-echelon model across warehouses today (single-pool in v1).

Why we built it

Forecasts are useful. Orders are decisions.

Stocktimal is built by RAW Analytics, a forecasting and operations-research consultancy. Our customers kept asking the same question: the forecast is good, now what do I order?

The answer is rarely “multiply expected demand by lead time and call it a day”. It depends on fill-rate targets, order costs, holding costs, minimum quantities, and the shape of the lead-time distribution. We wrote the methodology down, then turned it into software.

Stocktimal is the result. A thin, opinionated layer that takes the inputs you already have and produces a defensible order plan. No more, no less.
