How the Agent Works

    The agent gets a goal like generate monthly client invoices for a project, with access to time entries, expense records, rate cards, and billing policies.

  2. Plan

  3. Call tools

    The agent queries the time system, billing engine, CRM for project context, and the compliance module for approvals.

Worked Example

Generating a monthly invoice set with adjustments

Illustrative scenario with sample data.

Scenario

A medium-size consulting firm needs to bill 3 projects for the month, ensuring all time entries are properly coded and compliant with client terms. The agent runs overnight to prepare drafts for partner review.

Input

Goal: generate invoices for 3 projects. Data: time entries, expenses, project codes, client terms, rate cards, approval statuses, and last month’s ledger. Constraints: ensure all billable hours are captured and no prohibited items are billed.

What the agent does

  1. Pull time entries and expenses for Project A, B, and C from the time system and project ledger. The agent notes totals and flags missing approvals, then proceeds to rate application.
  2. Fetch client rate cards and apply standard and overtime rates, reconcile with discounts, and mark any rate deviations for review by a human.
  3. Validate compliance: project codes, client terms, required approvals, and audit logs; if issues are found, route to human for resolution before drafting invoices.
  4. Draft invoices for each project, summarize line items, attach supporting documents, and queue for management sign-off. If passes, finalize; if not, adjust and resubmit.

Output

Invoices drafted for 3 projects with items totaling 12,480.00 before tax. Line items: 8,900.00 hours, 2,300.00 expenses, adjustments 1,280.00. All approvals present; drafts stored in the billing system with audit IDs and client-visible notes.

Human decision

A billing supervisor reviews the drafts, confirms rate and discount accuracy, validates that all approvals are in place, and signs off before invoices are sent to clients.

What You Need

  • Access to time and billing system APIs and read/write permissions
  • Clean client rate cards and policy rules loaded in the system
  • Defined approval workflows and audit trail requirements
  • Logging of all actions, retries, and errors for compliance and traceability

Where People Stay in Charge

  • The agent cannot approve final invoices without human sign-off where client terms require explicit consent.
  • The agent should not modify approved discounts or write-offs without human validation and audit logging.
  • The agent must stop and report any data integrity issue or missing document to a human operator.
