erpware - Check your master data with us

We support you in checking your master data!

Master data management with the development of tools for automated checking of your master data is our strength.

ID Validation from erpware

We have new prices and a new licensing model. Learn more on our Purchase page.

The ID Validation is our software for checking your master data. The modular structure allows us to extend it and give you a central tool.

ID Validation

Our modules of ID Validation

VAT Validation

VAT Validation

Check all your VAT registration numbers to make sure they are valid.

EORI Validation

EORI Validation

Check all your EORI numbers for validity.

Duplicate Check

Duplicate Check

Clean up your addresses and find duplicate records.

The functions of ID Validation are extended via modules and are automatically available to every user as soon as we release them. This means that you will automatically benefit from new modules and thus always get more features to use as part of your licensing.

With the module VAT Validation we support the german legal change to 01.01.2021 (Abschn.18e.1. Abs. 5 UStA).

Tools and little helpers

For some time we have started to publish our tools that we use internally on this page.

AWS Manager

AWS Manager

Manage Amazon Web Services (AWS) resources and services.



Simplified working with your local directories and commands.

Unserer Tools


You can see more tools from us in our overview.

We will complete more tools little by little. The publication is mainly done as freeware. The process to publish an internally used software on our homepage is sometimes very time consuming. We add an update function, test the tool more extensively in terms of stability and, if necessary, even migrate it to our program language defined as standard in order to cut off the historical braids that were not necessary before.

Do you like a tool or use it on a daily basis? We have set up the possibility to support specific ones of these tools by sending a small donation via Paypal. With this income we reserve targeted capacities in our daily work to make the tools better or to expand them further.

Individual software from erpware

We not only develop and distribute ID Validation, but also develop individual software together with our customers. In the last years we have developed individual software for our customers several times. In doing so, we have successfully completed various forms ranging from concept development to the “pure” implementation of an existing concept or a very agile requirement.

Of course, after the development and release of the software is not the end. The software will be maintained and further developed.

We would be very happy to work with you to create a solution that is tailored to your needs.
