Open Source ERP: How to calculate the Total Cost of Ownership (TCO) really

The decision for a new Enterprise Resource Planning System (ERP) is one of the most strategic investments a company can make. In recent years, Open Source ERP has become an increasingly popular alternative to proprietary solutions. The main reason for this is obvious: no royalties apply.

But the true price of an ERP system often hides behind the purchase price. Here the Total Cost of Ownership (TCO) comes into play – a comprehensive review of all costs incurred over the entire life cycle of a software.

What is the Total Cost of Ownership (TCO)?

The Total Cost of Ownership is an analysis method that takes into account not only the initial purchase costs of an investment, but all costs incurred over their entire duration of use.

In the context of ERP systems, this means that, in addition to the purchase price, costs for implementation, adaptation, maintenance, training and support are also included in the calculation. A careful TCO analysis is essential to realistically assess the long-term economic viability of an ERP solution and to avoid bad surprises.

The cost factors for open source ERP systems

Short: Although Open Source ERP systems usually do not pay royalties, they are not free of charge.

Although Open Source ERP systems usually do not pay royalties, they are not free of charge. The following factors must be taken into account in a TCO assessment:

Implementation costs

The implementation of an ERP system is a complex process that goes far beyond the pure software installation. These include the analysis of business processes, the configuration of the system, the development of interfaces to other applications and the execution of tests.

These tasks require specialized know-how that must be either internally built or purchased by external service providers.

Adaptation and individualization

Rarely, a standard software fits perfectly with the individual requirements of a company. Open Source ERP systems offer the advantage that the source code is freely accessible and thus theoretically there are unlimited possibilities for adaptation. This flexibility, however, has its price: each individualization requires development expenditure which causes costs.

The more the system is adapted to its own processes, the higher these are.

Data migration

The acquisition of data from old systems is a critical and often underestimated cost factor. Data must be cleaned, transformed and imported into the new system. Depending on the extent and complexity of the data, this process can be very time-consuming and cost-intensive.

Employee training

The best software is useless if employees do not know how to use it. A comprehensive training of users is therefore essential for success
