Procurement that calculates. Inventory that fits.

PartsOS Planning replaces Excel-based forecasting and manual replenishment. Higher forecast accuracy. Lower inventory.
Clearer ordering decisions.

How it works

Three steps, clear responsibilities, no extensive onboarding.

  • Data comes in

    Data comes in

    Upload master data, consumption history, stock levels, and lead times from your ERP using a standard template. SAP, Dynamics, ProAlpha, ABAS, or custom systems - all common platforms are supported.

  • PartsOS calculates

    PartsOS calculates

    Demand forecast per SKU, 52-week horizon. Seasonality, maintenance cycles, and special effects are factored in automatically.

  • Review & approve order suggestions

    Review & approve order suggestions

    Per part: quantity, timing, supplier. Optimized to your service level target for minimum inventory and maximum availability. Accept or decline with one click.

You know how forecasting works

But ERP systems and manual order calculations push you to your limits the moment your assortment grows or demand becomes more volatile.

  • Demand forecasting in Excel & ERP

    Weeks of work, error-prone, and no one really trusts the numbers.

  • Double work without synchronization

    Forecasts and order suggestions are separate processes that never fully align.

  • Rarely the right level

    Inventory swings between overstock and stockout.

Operational scheduling becomes strategic planning

Forecasting and procurement on a single platform—without the need for expert Excel knowledge or weeks of training. With PartsOS, your planning team is productive from day one.

AI that knows your demand

Our ML models detect seasonality, lead-time variability, lifecycles, and sporadic demand patterns—delivering forecasts that stand up to S&OP scrutiny.

From forecast to order

PartsOS doesn't stop at the forecast. For every SKU, you see a concrete order suggestion with quantity, timing, and supplier, plus the revenue at risk if you don't act. Accept or decline with one click.

Scheduling without Excel know-how

Forecasts and order proposals in a single system. Lead times, MOQs, and supplier terms are automatically factored in—accept or reject with a single click.

What Changes for You

KPIs that measurably improve instead of blocking each other.

  • Higher Forecast Accuracy

    Higher Forecast Accuracy

    Unlike traditional forecasts, seasonality, maintenance cycles, and special effects are factored in automatically. Customers report forecast accuracy improvements of 20–40%.

  • Lower inventory, more free working capital

    Lower inventory, more free working capital

    Optimized to your service level target - tailored per part, not averaged across the assortment. Inventory reductions of 15–25% are the rule, not the exception.

  • Demand planning as a repeatable process

    Demand planning as a repeatable process

    No hidden Excel knowledge that disappears when someone leaves. Your planning process becomes transparent, traceable, and transferable.

FAQs from Supply Chain- and Procurement Teams

  • How does PartsOS integrate into our existing S&OP process?

    PartsOS integrates into any S&OP cycle—whether weekly, bi-weekly, or monthly. The forecast output can serve as a data basis for S&OP meetings without requiring you to change existing processes.

  • What forecast accuracy do customers typically achieve after 3-6 months?

    Most customers see a 20-40% improvement over their previous forecast level within the first six months. The range depends on data quality and assortment complexity.

  • How does PartsOS handle sporadic or volatile demand (lumpy demand)?

    Lumpy demand is the rule, not the exception, in spare parts. PartsOS uses models specifically designed for sporadic demand patterns and selects the right model per SKU - not a one-size-fits-all approach.

  • Can we enter minimum order quantities (MOQ), safety stock levels, and supplier conditions?

    Yes. MOQs, safety stock levels, service level targets, and tiered supplier pricing are all part of the standard input. PartsOS factors them in automatically when optimizing order suggestions.

  • How does PartsOS handle lead time variability?

    Lead times are incorporated as a variable in the model. If you have historical lead time data, PartsOS learns from the variability and reflects it in the safety stock calculations.

  • Are orders triggered automatically or only suggested?

    PartsOS makes suggestions. You place the order with one click in the replenishment view. Final decision authority stays with your team, with all the benefits of automated groundwork.

  • How do we handle ABC or XYZ classifications?

    PartsOS automatically classifies SKUs by demand pattern and value contribution, and adapts the forecast and replenishment strategy per class. Manual ABC/XYZ maintenance is not required, but can be overlaid if you prefer your own logic.
