You will then see this error: [This SKU has not been listed on Amazon](https://doc.common-services.com/en/article/error-this-sku-has-not-been-listed-on-amazon-amazon-marketplace-plus-1cex9jk/) (From version 5.4.08) ![Enable the feature: Create offers](https://storage.crisp.chat/users/helpdesk/website/-/3/f/a/8/3fa8ee645cd13200/screenshot380_9bf59x.jpg) --- ## Catalog > Amazon > Offers ![Amazon Offers Tab](https://storage.crisp.chat/users/helpdesk/website/-/3/f/a/8/3fa8ee645cd13200/screenshot1933_ctusfw.jpg) In **Catalog > Amazon > Offers**, you can access the operations for sending your offer feeds. The module uses a queue containing products marked as **“Update”**. If no products are in the queue, you can: * [Manually select products](https://doc.common-services.com/en/article/selecting-products-amazon-marketplace-plus-63kwn2/) * Or let [automatic logging](https://doc.common-services.com/en/article/understanding-the-logging-system-amazon-marketplace-plus-15fv9su/) detect changes | ⚠️ First Synchronization Recommendation: When performing the **first synchronization**, or after a long period without syncing, we recommend using the [Send Entire Catalog ](https://doc.common-services.com/en/article/product-stock-andor-prices-not-synchronised-with-amazon-amazon-marketplace-plus-1jpyjld/#2-3-resend-and-verify-the-catalog)option. --- ## Sending and Updating Offers By default: * The module sends only **quantities** and **prices** * It **updates existing offers** on Amazon (no product creation) * The unique identifier used is the **SKU**, corresponding to the **Reference** field in PrestaShop 📊 Once the feed is sent, check the [Report tab](https://doc.common-services.com/en/article/generating-the-report-amazon-marketplace-plus-ql3ave/) to verify Amazon's feedback. --- ## Options Adjust the content and behavior of the feed. ### Standard Options * **Extended Data** Also sends the **title, description, manufacturer, category node**, etc. * **Send Images** Adds images to the offer feed. ### Advanced Options * **Display JSON** Shows the feed content **without sending it to Amazon** (diagnostics/verification). * [Matching](https://doc.common-services.com/en/article/matching-automatic-offer-creation-amazon-marketplace-plus-mtz42n/) Attempts to associate your offers with existing Amazon products using **EAN/UPC**. * **Include List Price** Adds the strikethrough price (list price) to the feed. * **Include Latency** Includes the handling/preparation time (latency) before shipment. * **No Price** Sends offers without price (special cases). * **Send Entire Catalog** Forces a full feed submission (instead of only modified products). --- ### Matching To perform [matching](https://doc.common-services.com/en/article/matching-automatic-offer-creation-amazon-marketplace-plus-mtz42n/), first configure the [scheduled task for Report Listing Inventory](https://doc.common-services.com/en/article/scheduled-tasks-amazon-marketplace-plus-1j9uidk/#4-report-listing-inventory-url-to-fetch-save-data-report-listing-inventory). Then, you can select the **Matching** option before sending the feed to Amazon: ![Matching Option](https://storage.crisp.chat/users/helpdesk/website/-/3/f/a/8/3fa8ee645cd13200/screenshot363_dybadb.jpg) ||| To automate matching, you can also enable the Matching option in the [cron job settings](https://doc.common-services.com/en/article/configuring-cronjobs-parameters-amazon-marketplace-plus-1c19fyu/). --- ## In Case of Malfunction Before contacting support, ensure that: * Your products are [eligible](https://doc.common-services.com/en/article/eligible-products-for-export-or-synchronization-amazon-marketplace-plus-180uova/) * Logging is functional (check entries in the **Tools** tab) * You consistently review the **Report** after every feed submission --- ## In Case You Need Support Please provide: * The **generated JSON file**: see [how to generate it](https://doc.common-services.com/en/article/generate-the-json-file-amazon-marketplace-plus-1au8fym/) * The **Amazon report**: see [how to retrieve it](https://doc.common-services.com/en/article/generating-the-report-amazon-marketplace-plus-ql3ave/) --- ⏱️ To automate the process, you can configure a **cron job** for offer synchronization in the [Scheduled Tasks](https://doc.common-services.com/en/article/scheduled-tasks-amazon-marketplace-plus-1j9uidk/) tab.
