| Mistake | Why it causes problems | How to fix it |
|---|---|---|
| Missing service address or equipment details | The client may not know which property, system, or unit the invoice refers to. | Add service address, service date, system type, equipment location, model, serial number, or work order reference when available. |
| Not separating labor and parts | Clients may not understand how the total was calculated. | Separate technician labor, parts, equipment, refrigerant, fees, taxes, deposits, and discounts. |
