1. Navigate to Settings → Invoicing → Fuel Surcharge.
2. Enable Fuel Surcharge.
3. Enter the current surcharge rate (flat dollar amount or percentage of base rate).
4. Set the effective date - existing invoices are unaffected.
5. Click Save.

Fuel surcharge appears as a separate line item on all future invoices. Update the rate as needed - each invoice records the rate at the time it was created for audit purposes.
