Proper invoicing after diagnostic visit requires a sequential invoice number, separate labor ($263 for 2.5 hrs) and marked-up material ($182) lines for state sales-tax compliance, credit for any 50% deposit ($283), and clear due-on-receipt payment instructions.
Key Takeaways
- Send the invoice within 15 minutes of finishing diagnostic visit while the homeowner or property manager is still on-site.
- Separate labor ($263) from materials ($182) so sales tax only applies to taxable materials or services under state law.
- Reference compliance with UL/CSA OEM replacement part compliance & EPA Section 608 (sealed systems) and warranty terms directly in the invoice notes to prevent chargebacks and payment delays.
