Rock The Vote: WAP-I-6591 - Prevent users from adjusting invoice amounts for Invoice Types that are not T&M

I am writing to request improved system controls around invoice adjustment permissions, specifically for fixed-payment contracts.

We have identified a recurring issue where invoice administrators—sometimes with limited experience—are able to issue $0 invoices on fixed-payment contracts in an attempt to override the Invoicing Assistant. While this may appear to resolve short-term workflow challenges, it creates significant downstream issues during month-end close, including billing inaccuracies, reconciliation complications, and reporting inconsistencies.

From a control and audit perspective, the ability to issue zero-amount invoices on fixed-payment contracts introduces unnecessary risk. This behavior is not always intentional misuse but rather a lack of guardrails within the system.

We would like to request consideration of one or more of the following controls:

• Restricting zero-amount invoice creation on fixed-payment contracts

• Adding role-based permissions for invoice amount overrides

• Requiring approval or justification when invoice amounts are manually adjusted

• Providing a system warning or hard stop when users attempt to bypass the Invoicing Assistant

Stronger controls in this area would greatly improve billing accuracy and reduce close-related issues for our accounting and operations teams.

Thank you for your continued partnership. We would be happy to discuss this further or provide examples if helpful.
