IDS Connect: Increased efficiency through lean processes for craftsman
Digitalization is revolutionizing the skilled craftsman and with it the way skilled craft businesses organize their processes. The IDS Connect interface plays a central role in this. It enables a seamless connection between craftsman software and suppliers’ online stores. But what specific use cases does this technology open up? And how do businesses benefit from it? In this article, I shed light on the potential of IDS Connect and highlight practical applications.

Why IDS Connect is indispensable!
The demands on craft businesses are growing. Customers expect fast quotations, precise calculations and swift order processing. At the same time, internal processes must be designed efficiently in order to remain competitive. Craftsman software supports these processes. Providing them with up-to-date information requires a great deal of manual maintenance. This is where the IDS Connect interface comes in. IDS stands for “Integrated Data Interface” and enables the following applications:
- Direct access to current article data such as prices, images, texts and availability
- Automated data exchange between craftsman software and suppliers’ online stores
- Reduction of manual work steps, which saves time and minimizes errors
For example, craftspeople used to have to manually transfer product data from catalogs or quotations into their system. This is a time-consuming and error-prone process, especially in dynamic markets. IDS Connect digitizes this step.
Use cases of the IDS Connect interface in practice
Various use cases can be optimized with this interface. Below you will find five possible applications:
Efficient shopping cart processing
A central use case of IDS Connect is the processing of shopping baskets.

Practical example:
A company in the air conditioning technology sector uses its craftsman software to create a shopping cart with the materials required for the customer order. This is sent directly to the supplier via IDS Connect. Alternatively, the company can import a shopping cart created in the online store into its software for further processing – whether for calculations, quotations or orders.
Advantages:
- No double data entry
- Time savings through automated processes
- Direct further processing of the data in your own software
Direct access to article data
IDS Connect makes it possible to call up article information such as prices, availability or technical details in real time. There is no need to leave the system and the interface accesses the required information in the “background”.

Practical example:
An installer is on site with a customer and realizes that a spare part is needed. Using the “Article Deep Link” function, he calls up the availability of the article from the wholesaler directly from his software. He can order the item within a few seconds. And without any detours via the office.
Advantages:
- Real-time data saves unnecessary inquiries
- Inspire customers by passing on information quickly
- Optimization of the entire process from the quotation to the order to invoice processing with the supplier
Quotation preparation
IDS Connect makes it much easier to create quotations, as current article data can be integrated directly.

Practical example:
A roofer visits a customer on site and discusses the plans for the new roof with them. Using the integrated data interface (IDS Connect), he adds current prices and availability directly to his quotation. The finished quotation is sent to the customer by e-mail within a few minutes.
Advantages:
- Fast quotation preparation increases customer satisfaction
- More precise calculations thanks to daily updated data
- Reduced administrative effort thanks to automated processes
Order processing
The IDS interface also offers considerable advantages when processing orders, as all relevant data is available centrally.

Practical example:
A drywall builder receives an order for additional objects. He uses IDS Connect to access his supplier’s item data and imports it directly into his order. Changes or additions can be made in real time without having to overcome media disruptions between different systems.
Advantages:
- Efficient order processing through direct integration of article data
- Seamless communication between tradesman software and online store
- Error reduction through automatic data transfer
Always up-to-date data thanks to integration of supplier systems
IDS Connect creates a seamless connection between craftsmen’s software or their ERP system and the suppliers’ online stores. This means that article data is always up-to-date in your own system.

Practical example:
A painting company uses IDS Connect to access its wholesaler’s store system directly from its software. There he can search for products, compare prices and place orders. And all this without leaving the software.
Advantages:
- Centralized processes without media disruptions
- Increased efficiency in product search and ordering
- Better overview of available products
Advantages of IDS Connect for trade businesses
The introduction of IDS Connect brings numerous advantages:
- Time saving: routine tasks such as manually transferring data are no longer necessary
- Error reduction: Automated processes minimize input errors
- Cost control: Costs can be calculated more precisely thanks to daily price queries
- Flexibility: data can be called up at any time, whether in the office or on the construction site
- Customer satisfaction: Fast quotation and order processing strengthens the relationship with the customer
Which ERP or craftsmen software offers this interface?
Here you will find an overview of software providers that offer the IDS Connect interface. Depending on the license model and software maturity, providers may be missing. I recommend contacting the current or potential software provider directly to discuss the details.
- HERO Software
- Handwerksd ata
- Haufe X360 Cloud ERP from Nexaion integrated
- Streit V.1
- Landrix Handwerk
- Das Programm
- Pds Software
- M-Soft
- LC-Top
What needs to be considered during implementation?
Data quality is the foundation of the process. Article master data should be stored cleanly in the craftsman software. This means that the article number must contain a unique number. The manufacturer’s article number or the EAN number can be used here. This is important so that the items can be identified via the interface.
It is also important to look at the processes and objectives . Not every option that can be implemented with this interface is relevant for your company. The individual steps need to be defined before the technical implementation.
If colleagues and employees are involved, they should be involved at an early stage. Acceptance can arise through participation. After all, what good is the best data quality and a first-class process if they are not used?

What is the difference to OCI, UGL, OMD, cXML Punchout and the DATANORM catalog format?
In addition to IDS Connect, there are other interfaces and data formats that enable cross-system work. The following section should help to highlight the differences. These “tools” for optimal processes depend on the selected system (e.g. tradesman software, ERP system), the objective and the technical capabilities of your most important suppliers.
OCI interface
OCI stands for Open Catalog Interface. This interface was developed by SAP and has become standard in many ERP systems. Companies from the manufacturing industry in particular rely on this interface. There are now also special purchasing systems, also known as e-procurement systems, that rely on this interface.
Function:
- Import articles from the supplier’s online store into the tradesman software or ERP system.
Difference to IDS-Connect:
- A separate interface (e.g. EDI) is required for the transmission of orders
DATANORM Catalog
DATANORM is a structured data format that was developed for the creation and maintenance of article data in craftsman software. It contains rudimentary data such as article number, description and price. This catalog format is also referred to as static, as a new DATANORM catalog must be created by the supplier each time a change is made and must be imported into the craftsman’s software.
Function:
- Creation and maintenance of article data
Difference to IDS-Connect:
- Static catalog format as opposed to the dynamic IDS interface, also known as dynamic catalog
- Article creation possible in the craftsman software
- Supplement to IDS Connect. First create the articles with DATANORM and then keep prices up to date with IDS Connect
OMD interface
OMD stands for Open Masterdata. Like the IDS Connect interface, OMD was developed by ITEK GmbH. Anyone working with the DATANORM catalog format can use it to add missing information such as images or data sheets as required. In the medium term, OMD is intended to replace the outdated DATANORM format.
Function:
- With Open Masterdata, article data can be retrieved from the supplier in real time. This requires an article number or the EAN (or GTIN). This can be entered manually or selected from the DATANORM catalog.
Difference to IDS-Connect:
- For articles that are not in the article data master in the craftsman software, images, texts, prices or service specifications can be called up, for example
- Creation of new articles in the craftsman software possible
- Similar function to the “article deep link” of IDS 2.5, but a different data standard
UGL interface
UGL is the abbreviation for “Übergabeschnittstelle Lang”. This was originally developed by the wholesale group “GC Group”. The UGS description (transfer interface) served as the basis for this.
Function:
- An Excel file will be downloaded from the supplier’s online store. The information it contains is used to create quotations or orders. The focus of this “interface”, which is more like a catalog such as DATANORM, is the exchange of documents.
Difference to IDS-Connect:
- IDS-Connect is an automatic and modern interface. With UGL and UGS, the data must be imported manually
- Pure focus on the exchange of documents such as orders
cXML Punchout Catalog
The Punchout catalog works in a similar way to the OCI standard and was developed by Ariba in the USA. Systems from Oracle, coupa or SAP Ariba rely on this standard. Orders can be transmitted via this interface in a similar way to IDS Connect. It is also possible to return order confirmations, shipping notifications or invoices.
Function:
- Import articles from the supplier’s online store into the tradesman software or ERP system.
Difference to IDS-Connect:
- A separate interface (e.g. EDI) is required for the transmission of orders
- Can import the supplier’s return messages into the craftsman’s system via the interface in addition to the order
