Open Document Exchange (ODX)

The Open Document Exchange (ODX) standard maps the content of digital documents and their transportation - i.e. document transmission. Every day, a large number of documents are exchanged between wholesalers and tradespeople using different methods and formats. This inconsistent transmission requires a great deal of manual processing and poses a challenge for invoice verification.

To solve this problem, the BVBS - Bundesverband Software und Digitalisierung im Bauwesen, the DG Haustechnik - Deutscher Großhandelsverband Haustechnik and the ZVSHK - Zentralverband Sanitär Heizung Klima have developed the Open Document Exchange (ODX) standard.

The standard allows electronic business documents to be exchanged between wholesalers and craftsmen. Similar to the ZUGFeRD invoice, documents are no longer exchanged between the market partners on paper, but in a hybrid format. Hybrid means that a PDF is transferred in which an automatically processed data structure is embedded in XML format. This means that these receipts can be easily read and stored as a PDF, i.e. paperless, but also serve as the basis for fully automated project billing or invoice verification.

Use case counter process

The first use case to be digitized with ODX was the “counter process”. When picking up goods, craftsmen can now use a standardized QR code to communicate the associated construction project or project to the corresponding wholesale company, so that the order confirmation and delivery bill documents triggered by the pick-up are provided with a project or process ID, so that data that can already be processed immediately after pick-up is transferred directly to the trade software.

Further use cases will follow, as ODX can of course also be used for quotation or order management.
