Instead of entering thousands of items manually, you use a catalog as your source. This keeps your own item file clean and compact, while still giving you access to your supplier’s full range. #### Catalog Browser With the Catalog Browser, you can search through tens of thousands of products in no time, without them being in your own stock list. Do you need a part you have never sold before? Look it up in the browser, view the images and specifications, and add it to a Work receipt or sales order with one click. Powerall then creates the item for you in the background with the correct details. #### Version control and updates Product information and prices change continuously. Powerall keeps an eye on this for you. For each catalog, you can immediately see whether an update is available. When you run an update, new products are added, discontinued items are marked, and price changes are applied immediately. That way, you never work with outdated information. #### Revenue groups and automation For each catalog, you can set in advance which revenue group new items should be assigned to by default. This means that even if you sell a new product from the catalog, the financial posting is immediately correct in your accounting. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.powerall.app/en/parts/suppliers/catalogs.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
