# Update: Checkout & Invoice Cost Breakdown for Gen3 AiX Extensions This change introduces a more detailed cost breakdown in the migration cart and on all invoices. *** ### 1. Checkout Flow Change * **Before**: The migration cart grouped the "extension cost" and "shipping cost" together under a single "**Shipping Cost**" line item. * **After**: The cart now bifurcates (separates) these. Customers will see two distinct line items: * Extension Cost * Shipping Cost *** ### 2. Impact on Invoicing * **New Orders**: Any order placed after this release will automatically generate an invoice that reflects this new, separate cost breakdown. * **Existing Orders**: Invoices for all existing orders are available.They can be downloaded from the order details page and will also show the correct, bifurcated cost breakdown. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
