Wer Liefert Was? – literally translated “who delivers what?” is a service which allows you to search for manufacturers, service providers, distributors and wholesalers in Germany. The call them self “The Supplier Search Engine in business-to-business”. You can search by Product, Service or company name. The system has kind of a controlled vocabulary which shows suggestions while you type in the search box.

The advanced search allows you the use AND, OR and NOT by typing the words in the corresponding input boxes. The company claims that every month more then 1.5 million search are conducted and their site had over 23 million visits in 2008. This service is available since 75 years. Naturally they started of in printed form before they started their database and later web services.

Once you are on the hit list you can see the classification of the hit (manufacturer, service provider, distributor and wholesaler) and you can click on the hit and see details of the company represented by the hit. By using the “Data of your contact” you can display contact details of the sales of this company. If you want to know more you click on “Company information” to get detailed information about the company. This includes contact details, products and services offered and sometimes even a kind of org chart with the function of this person in the company (a feast for every headhunter which needs to build up a client organization in Germany .

All results can be printed or exported as PDF. The addresses can be sent to you address book (e.g., MS Outlook). The search order is a kind of mystery to me – I assume there are premium entries which rank higher but you can narrow down by post code, place and supplier type.

Besides their German origin the company offers their services in Austria, Switzerland, Czech Republic, Croatia and Slovakia. The service is not only a great source for purchasing goods but also if you want to get your product or service sold in the covered areas of WLW.
