How SMEs can free up liquidity – optimize working capital

My working capital is too high – what should I do?

Excessive working capital ties up liquidity, increases financing requirements and raises operational risks. Active management is therefore a key success factor, particularly for SMEs with limited financing options. In this article, you will learn:

  • What exactly is working capital?
  • What levers are available for optimisation
  • What risks should be considered and
  • Which key figures you can use to manage your working capital professionally.

The blog is available in both a fold-out and a full view. Enjoy reading!

1. What is working capital?

Working capital is calculated as follows:

Inventories + receivables – liabilities

It describes the capital tied up in operational business that is necessary to maintain the business model.

There is often talk of core working capital. This can be supplemented by other receivables and liabilities. However, these items can usually only be influenced to a limited extent, as they are often subject to legal requirements and late payments can result in penalties or interest.

In manufacturing companies, inventories are divided into three categories:

  1. Raw materials, consumables and supplies (RCS)
  2. Semi-finished products
  3. Finished products

High inventory levels not only lead to tied-up capital and higher financing costs, but also to:

  • Increased storage and handling costs
  • Obsolescence and depreciation risks
  • Price and sales risks

2.1 Targeted management of raw materials, consumables and supplies

Proven optimisation measures include:

  • Consignment warehouse with suppliers

For sustainable results, a structured analysis is recommended:

ABC analysis

  • A items: high value, low quantity → low stock levels, frequent replenishment
  • B items: medium value → regular review
  • C items: low value, high quantity → larger order quantities

XYZ analysis

  • X article: stable consumption, easily predictable
  • Y-articles: fluctuating consumption (e.g. seasonal)
  • Z items: irregular, hardly predictable consumption

Combined ABC/XYZ matrix (practical approach)

  • AX: Just-in-time, minimal stock levels
  • AY: forecast-based procurement
  • AZ: individual single-item planning
  • CX: large order quantities
  • CZ: no stockpiling if possible

Important: Any optimisation must take supply chain security into account in order to avoid production interruptions.

2.2 Semi-finished and finished products

  • Semi-finished products are an essential component, particularly in modular manufacturing and plant engineering.
  • Finished products are considered particularly sensitive:

o Reduced capacity utilisation worsens the cost structure

o High inventories increase obsolescence and price risks

Close coordination between sales, production and planning is crucial here.

Possible measures could include, for example:

  • Increase in inventory turnover (e.g. sales promotions for slow-moving items)
  • Dropshipping in retail (direct shipment from supplier to customer)

The amount of accounts receivable is largely determined by payment terms. These reflect market practices and negotiating power.

  • Austria / EU: usually 30–90 days
  • Asia: up to 240 days in some cases

Long payment terms tie up capital and increase the risk of default.

Recommended measures:

  • Short, clearly defined payment terms
  • Define payment terms based on customer creditworthiness
  • Consistent receivables management (dunning process, escalation levels)
  • Targeted use of discounts (effective but expensive)
  • Factoring as an alternative, especially for customers with strong credit ratings

Liabilities are the mirror image of receivables. Basic rule:

Payment terms for suppliers should be at least as long as those for customers.

  • Discounts are usually economically attractive
  • Nevertheless, payment dates should be consciously managed with regard to balance sheet dates and key figures.

The most important key figure is the cash conversion cycle (CCC). It shows how long capital is tied up in the operating process.

Components of the CCC

  • Days Inventory Outstanding (DIO) – Storage period
  • Days Sales Outstanding (DSO) – Accounts receivable turnover
  • Days Payables Outstanding (DPO) – Supplier payment terms

Overview of KPI

KPI

Formula

DSO

(Receivables / Turnover) × Days

DIO

(Stock / Turnover) × Days

DPO

(Liabilities / Purchases) × Days

CCC

DSO + DIO – DPO

Effective management requires:

  • Clear target values for each KPI
  • Regular reviews with those responsible, e.g. sales, supply chain
  • Understanding within the organisation that working capital is not purely a financial exercise, but rather an operational success factor

Benchmarking with competitors or peer groups increases transparency. AI-supported analyses for inventories are particularly efficient in complex manufacturing processes and replace time-consuming manual evaluations.

Working capital is one of the biggest drivers of financing requirements, alongside fixed assets. Targeted optimisation:

  • Reduces capital requirements and financing pressure
  • Reduces operational risks (obsolescence, bad debts)
  • Improves transparency and controllability

The following factors are crucial for success:

  • Clear prioritisation of measures
  • Quick wins to increase acceptance
  • Sustainable anchoring within the company

After a successful optimization round, the focus shifts from further cost savings to fine-tuning and consistent management.
