Hi,

To generate a list of invoices associated with your outside sales reps (represented by customer tags) without custom programming in Odoo, the key is to ensure you're tagging the customer record directly, not just the sales order. With this in place, you can leverage Odoo's built-in features.

One approach is to use Odoo's built-in filters and grouping within the Invoices list view. Create a custom filter that selects customers who are members of your sales rep tag. Save this filter for easy reuse. You can also use the "Group By" option to organize invoices by customer tag.

Another method is to utilize Odoo's reporting features, specifically the Pivot and Graphical views. The Pivot view allows you to analyze invoice data based on different dimensions, including customer and tags. The Graphical view provides a visual representation of the data, allowing you to group invoice amounts by customer and tag.

Finally, if you need more advanced analysis, you can export the invoice data to a spreadsheet. Apply the filter you created earlier, export the data (including customer name, invoice number, amount, and tags), and then perform further analysis in your spreadsheet program. By tagging the customer and using these built-in features, you can effectively track invoices associated with your sales reps without custom code.

Hope it helps
