Filter combinations can be saved as templates per user. ## Step-by-step guide ### Step 1: Open the filter flyout → Open directly in the app: [app.arbitrageone.de/productsheets](https://app.arbitrageone.de/productsheets) At the top, next to the **Filter templates**, click the filter icon to expand the flyout. Expanded filter flyout with all filter options and templates area ### Step 2: Use multi-select filters The following dropdowns allow multi-select with live search: * **Purchase source**: source of the deal (Rossmann, Müller, Idealo …) * **Category**: Amazon category (Website Display Group) * **Marketplace**: target marketplace (DE, FR, IT, ES, UK …) * **Sourcing strategy**: strategy assignment (e.g. Online Arbitrage, Retail Arbitrage) * **Tags**: your own tags * **Rating**: 1 (Bad) to 5 (Good) ### Step 3: Filter price ranges * **Purchase price gross (€)**: min/max range for the purchase price * **Selling price (€)**: min/max range for the selling price ### Step 4: Apply filters Click **Apply** — the table updates with the active filters. ### Step 5: Save filter as a template Under **Filter templates** enter a template name and click **Save**. Saved templates can be recalled at the top next to the filter icon. ## Notes on ROI and Margin * **ROI**, **Margin** and **Breakeven** are shown per row as coloured badges (traffic-light system based on your thresholds in **Settings → Calculation**). ## Common issues **Issue:** Filter doesn't apply, table shows old results **Solution:** Reload the page. For very large sheets, the filter can take 1–2 seconds to take effect. **Issue:** A saved filter template has disappeared **Solution:** Templates are saved per user. If you work across multiple devices, it should be consistent — if there are problems: clear the browser cache and log in again. **Issue:** "Purchase source" doesn't show a shop **Solution:** Shops only appear if at least one deal has them as a source. Add the source to at least one deal. ## Related articles * [How do I set up my calculation basics?](../erste-schritte/kalkulationsgrundlagen-einrichten)
