Invoice review
Use a draft invoice to compare the billed period and line source with the engagement agreement.
Period review
Inspect open WIP and provisional revenue before the Controller locks a period.
Professional service teams billing by time and expenses. Project Billing System gives the team a contract, project, billable work and invoice history for each customer engagement. Project manager can review the commercial context while billing specialist prepares charges and Controller handles approvals and period accounting.
For an advisory engagement, the agreed time and materials contract sets the rate basis. Project manager checks hours across assignments before billing specialist rolls them into a draft. An expense keeps its approved source and markup beside the time charge. If the customer questions a line, the team follows the source junction instead of changing the approved hours without review.
Choose one active project and one customer. Enter its contract, rate basis and billing schedule. Bring in a small approved work batch with stable source identifiers. Prepare a draft and have project manager trace a time line and an expense line back to the original work. Rehearse one item that should be excluded, then review the remaining draft and the approval decision. After sending, follow its due date and payment amount. Review the same project in WIP and revenue entries for the period. This establishes a repeatable path for the next engagement without changing prior invoices.
