Milestone Billing & WIP

Q: Can automation handle different billing schedules and contract types?

Yes, automation reads contract terms and billing schedules from stored documents and applies the correct logic for each client and project type.

Q: Will existing invoices and WIP records be affected?

No, automation works with your current data and updates records going forward. Historical data remains unchanged.

Q: What tools does automation connect to?

Automation integrates with your project management system, accounting software, document storage, and email to validate, generate, and send invoices automatically.

Q: Do I still need to review invoices before they go to clients?

Yes, automation routes each invoice to finance for final review and approval before sending. You maintain full control over what goes out.

Keep revenue flowing by automatically converting approved project milestones into accurate client invoices the moment they are signed off.

About This Automation

Milestone billing at systems integration firms requires manual verification of project completion, contract terms, and revenue recognition before invoicing. This process is slow and error-prone, with finance teams spending hours each week cross-checking spreadsheets, emails, and project boards.

Automation validates billing eligibility, calculates correct amounts, and routes invoices for review and sending. The result is same-day invoicing with zero billing errors and faster cash collection.

Key features:

Validate billing eligibility against contract terms and project scope automatically

Calculate correct invoice amounts based on milestone definitions and billing schedules

Flag contract exceptions and billing holds for manual review before invoicing

Sync milestone completion status from project management to billing systems

Generate and send invoices with one-click approval from finance

Update revenue recognition and WIP records in real time

How The Automation Works

The full workflow, from trigger to completion.

1. Milestone Marked Completetrigger

Automation detects when a project milestone status changes to 'Complete' and captures the project ID, milestone name, and completion date.

2. Fetch Project and Contract Details

The automation retrieves the full project record, including client name, contract ID, and billing terms, then looks up the corresponding contract document metadata.

3. Validate Billing Eligibility

The automation reviews the contract terms, milestone completion date, and project scope to confirm the milestone is billable and calculate the correct invoice amount based on the contract.

4. Create Invoice

The automation creates a new invoice with the client name, billing amount, milestone description, and due date automatically populated from the project and contract data.

5. Send Invoice

The automation sends the invoice to the client email address with a templated cover message and payment instructions.

6. Update WIP and Project Records

The automation updates the internal WIP tracking spreadsheet and logs the invoice number and send date back to the project record.
