In the "Buyer Direct" EIPP model, what do sellers do?

In the "Buyer Direct" Electronic Invoice Presentment and Payment (EIPP) model, sellers post their invoice data directly to the buyer's system. This approach allows buyers to easily access and review the invoices associated with their purchases without needing to go through a third-party intermediary. By posting invoices directly, sellers can ensure that the information is accurate and that the buyer has immediate and secure access to the details necessary for payment processing.

This model streamlines operations and facilitates quicker payments, as buyers can directly view and process invoices in their own systems. It promotes better communication and reduces the likelihood of discrepancies between sellers and buyers regarding invoicing.

The other options describe functions that do not align with the core process of the Buyer Direct model. Charging buyers directly relates to payment terms rather than invoice presentation, negotiating prices is generally a separate transaction process, and processing payments for the buyer is not part of the invoice presentation but rather an outcome that depends on whether the invoice data has been successfully reviewed and approved.
