💬 Real Conversation Examples

👆 Click to see actual conversations from the demo system ### **📄 Invoice Submission Query** ``` 👤 User: How do I submit an invoice? 🤖 Assistant: Log in to the supplier portal, navigate to Invoices → Create, enter the PO number (if applicable), upload your PDF or XML, review the preview, and click Submit. ``` ### **💰 Payment Status Inquiry** ``` 👤 User: Check payment status 🤖 Assistant: Open Payments → Remittances in the portal to download remittance advice PDFs. You can also enable email remittances under Settings → Notifications. ``` ### **❌ Issue Resolution** ``` 👤 User: Invoice was rejected 🤖 Assistant: Go to Invoices → All, click the rejected invoice, and review the Rejection Reason in the Activity panel. Correct the issue and use the Resubmit button. ``` *✨ All responses showcase patterns learned from AWS SageMaker training on real support documentation*
