Every sheet automatically shows up in the Sourcing Mastersheet, unless you explicitly exclude it. ## Requirements * Logged-in ArbitrageOne account * **Google Sheets / Sourcing** permission on your plan ## Step-by-step guide ### Step 1: Open the overview → Open directly in the app: [app.arbitrageone.de/productsheets](https://app.arbitrageone.de/productsheets) Navigate to **Sourcing → Sheets**. You'll see a table of all existing sheets with **Title**, **Created**, **Discord webhook** and **SKU prefix**. Use the search field at the top right to find sheets by name. Sourcing Sheets overview with existing sheets and plus button in the top left ### Step 2: Create a new sheet Click the **+** symbol at the top left. The **Create new Sourcing Sheet** modal opens. Modal "Create new Sourcing Sheet" with all fields ### Step 3: Fill in required fields * **Name**: meaningful title (e.g. "Rossmann DE October") * **SKU prefix**: max. 3 alphanumeric characters (e.g. `ROS`) — becomes part of your generated SKUs so you can identify the origin later ### Step 4: Set optional fields * **Discord webhook**: which Discord channel gets notified for new deals in this sheet * **Default shipping address**: pre-set shipping address for purchases from this sheet * **Default payment method**: pre-set payment method when recording a purchase * Toggle **"Products from this sheet should not appear in the Mastersheet"**: enable if the sheet should be excluded from the Mastersheet view ### Step 5: Save Click **Save**. You're returned to the overview and see your new sheet in the list. Click the title to open it. ## Important notes * The **SKU prefix** cannot be changed once rows exist in the sheet — choose it deliberately. * **Deleting** works cleanly only for empty sheets. If deals are inside, exclude the sheet from the Mastersheet view via the Mastersheet toggle instead. * There's no fixed hierarchy between sheets — structure them via **naming conventions** and **SKU prefixes**. ## Common issues **Issue:** "SKU prefix already in use" **Solution:** The SKU prefix must be unique within your account. Choose 3 different characters. **Issue:** Sheet doesn't appear in the overview after saving **Solution:** Reload the page. If it's still missing, check your user rights (VAs may only have access to assigned sheets). **Issue:** My created deals end up in the wrong sheet **Solution:** In Record Purchase or the Analyzer dialog, explicitly select the target sheet in the **Sourcing Sheet** dropdown. ## Related articles * [How do I use the Analyzer for product evaluation?](analyzer-nutzen)
