What are the four planning classes?

Forecast monthly and forecast quarterly for parts with regular demand, safety stock / reorder point for parts with sporadic demand, make-to-order for parts without meaningful demand. PartsOS assigns every part automatically.

PartsOS fits companies with long-lived machinery and equipment across industries — validated for: machine & plant engineering, automotive aftermarket, commercial vehicles & fleet operations, rail technology, aviation/MRO, process industry (incl. food & packaging), energy, building technology & facility services, healthcare/medtech, and agricultural/construction equipment dealers. The validated core customer with real references today is machine & plant engineering.

Does the export change anything about my ERP rules?

PartsOS gives you new values for safety stock, reorder point, and min/max. Whether you take them into your ERP is your decision – nothing is overwritten without your export.

Does PartsOS use the same method for every part?

No. Each part gets whichever method was most accurate on its own history and that can change from cycle to cycle.

Do I have to review every part manually?

No. PartsOS plans the portfolio through and only presents you with the parts where a decision from you is needed.

Do I need forecasts for this?

No. For most spare parts, dynamic safety stock and reorder points are a better way to plan. PartsOS only calculates forecasts for the parts where they measurably help.

How long does implementation take?

Upload two files: master data and consumption history, with three mandatory fields. Choose your target, and you're done. The first parameters are available the same day.

100 % of your parts portfolio planned. Automatically.

PartsOS calculates safety stock, reorder point, and min/max levels for every spare part and writes them back into your ERP.
No IT project, two files, first results the same day.

Your customers can rely on you. We make sure of it.

When the right parts arrive on time, you're not the only one who notices, your customer does too. That's exactly what PartsOS makes possible.

Our promise

From reactive to proactive planning

Every part has a rule

PartsOS automatically divides your entire portfolio into four planning classes. No part is left unplanned, not even the 80 % that cannot be forecast.
Parameters instead of gut feeling

Safety stock, reorder point, and min/max levels are calculated dynamically from your history, lead time, and your target availability – not set once and forgotten.
One click into the ERP

All parameters leave PartsOS in your ERP's format. Your ERP orders and books as usual, just with better numbers.

How it works

Planning classes

PartsOS checks every part and classifies it automatically: forecast monthly, forecast quarterly, safety stock / reorder point or make-to-order. You see at a glance how your portfolio is planned.
Your target, our calculation

You choose what counts: hold inventory, reach target availability or reach target stock level. PartsOS derives the parameters for every part from that and shows you when you will reach the target.
ERP export

Safety stock, reorder point, min/max, and – where it makes sense – planned primary demand as a ready-made file in your ERP's format. You only have to review the few parts where PartsOS needs a decision from you.

PartsOS fits more than one industry

For companies with long-lived machines and equipment

Machinery and plant engineering (OEMs)

Machines that run for 20–30 years need planning that thinks that far ahead. PartsOS shows which parts are worth stocking – and at what level- before a rush order eats the margin that after-sales is meant to build.

Automotive Aftermarket

Broad ranges and thin margins leave no room for capital tied up on the wrong shelf. PartsOS shows which parts are worth stocking and counts dead capital honestly instead of hiding it.

Commercial vehicles and fleet operations

When parts supply runs on a quick call to the dealer, the forward view is missing. PartsOS tells you which parts the fleet will need in the coming weeks, before a vehicle ends up in the workshop for want of one.

Rail technology

Certified assemblies and a shrinking supplier base leave no room for short-term planning. PartsOS gives you the right inventory parameters for every part, so the order goes out before the bottleneck appears.

Aviation MRO

With serialised rotables and global pooling arrangements, an early view of the right inventory parameters for every part without tying up more capital than necessary.

Process industry

Nobody enjoys clearing out stock that hasn't moved when nobody can say what's still genuinely needed. PartsOS shows which parts are worth stocking and at what level.

Energy sector

Critical components with over a year of lead time leave no room for reactive planning. PartsOS gives you the right inventory parameters for every part a growing installed base needs.

Building services

When hundreds of technicians work out of rolling stockrooms to meet SLA deadlines, every missing part counts twice. PartsOS shows which parts are worth stocking (and at what level) before an appointment falls through because of it.

Medical technology

When availability is contractually guaranteed and subject to documentation requirements, gut feel isn't enough. PartsOS provides the right inventory parameters for every part.

Agricultural and construction equipment dealers

When the parts warehouse is the most profitable part of the business, seasonal demand is worth a close look, before a customer is already waiting.

"Our goal is to provide our customers with the right spare part exactly when it is needed. With PartsOS Forecast, we are transforming our inventory management into a data-driven, dynamic control system that is consistently aligned with service levels and places a much stronger focus on spare parts management."

Hannes Malczewski

Interim Head of SP Shipping & Project Coordination

"Our goal was to be a leader in service. With PartsCloud, we have finally achieved this: data-driven security in spare parts planning. What used to be reactive and manual is now proactive, automated, and fully under control."

Michel Ahring

Head of Division Service

"PartsCloud is a strategic partner for us. Together, we are defining the path to modern spare parts planning with the goal of reducing manual processes and improving availability. The collaboration is particularly valuable: technically strong, pragmatic, collaborative, and with genuine mechanical engineering expertise."

Christian Meisen

Lead Lifetime Services

"We greatly value the high level of mechanical engineering expertise and the hands-on experience of the PartsCloud team. They quickly understood our specific challenges and translated them into a smart solution that fits perfectly into our limited ERP setup. With PartsOS, planning is now automated and reliable, giving me personal peace of mind."

Rüdiger Stanzel

Head of Aftersales

"From the very beginning, the collaboration with PartsCloud has been a genuine dialogue on equal terms. The team not only brings deep experience in the industrial spare parts business, but also understands the specific characteristics of the rail segment. We look forward to the next steps and fully utilizing the system's potential."

Claudia Kratz

Commercial Manager

"We didn't want a tool, we wanted trust. PartsCloud showed us how data-driven planning really works. Today we can say with complete conviction: We have our spare parts planning under control."
