Supplier matching proposals make this process smart and largely automatic. It is the ‘matchmaker’ between your warehouse and the outside world. #### Matching When you import a new catalog, Powerall looks for matches. Based on item numbers, EAN codes and descriptions, the system makes suggestions: "This product from the catalog looks a lot like your item X". All you need to do is review and confirm these proposals. #### Price deviations One of the most important functions of the matching proposal is insight into price differences. The system shows you immediately where the new catalog price differs from the purchase price currently stored in your system. * **Increases**: See immediately where your margin is under pressure. * **Decreases**: Take advantage of sharper purchasing conditions. You can filter by the size of the deviation, so you can process the most important changes first. #### Tips Do you have hundreds of proposals? With bulk actions, you can process large groups of links at once. You can specify that all matches with a small price deviation may be approved automatically, while you review the large differences manually. That way, your item file stays 100% up to date with minimal effort. --- # 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/supplier-linkage-proposals.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.
