Loading builder…

A typical HVAC ticket mixes a trip charge, hourly labor, and refrigerant by the pound. This preset separates those so the homeowner sees the breakdown.

After the customer approves

After the customer signs or approves, click Convert to invoice in the sidebar (next to Download PDF). You do not retype line items, the tool assigns a new invoice number, today's date, and Net 30 due date, then opens the invoice builder for a final review.

Use the Convert to invoice button in the summary panel on the right.

HVAC questions

How does estimate to invoice convert work?

Click Convert to invoice in the sidebar. Line items, business and client blocks copy over. You get a new INV- number, today's issue date, Net 30 due date, and any deposit field cleared. Edit anything before you download the invoice PDF.

What carries over when I convert?

Line items, quantities, rates, notes, tax rate, and discount settings. The estimate number stays on the old PDF only, the invoice uses the next number from your browser counter.

Do I need to re-enter the client after convert?

No. Parties and line items copy automatically. You land on /invoice with the form prefilled; review due date and totals, then download.

What should an HVAC invoice include?

Business license, EPA 608 cert if handling refrigerant, line items for diagnostic fee, labor hours, parts, refrigerant type and quantity, and payment terms. Our PDF footer reminds clients this is not tax advice.

How do I bill refrigerant on an HVAC invoice?

Add a line item with unit "each" or lump sum, note the refrigerant type (e.g. R-410A) in the description, and list pounds recovered or added. Keep EPA log records separately for compliance.

Should I charge a diagnostic fee on estimates?

Many shops quote a flat diagnostic or trip fee that applies to the repair if the customer proceeds. List it as its own line so the estimate total matches what you discuss on site.

Estimate vs invoice for HVAC replacement?

Send an estimate with equipment model, warranty note, and valid-until date. After approval, convert to an invoice with the same line items and a new invoice number, our tool supports one-click estimate→invoice.
