Contractor Invoice Maker

New estimate

Scope the job, set a valid-until date, and download an ESTIMATE PDF. When the customer approves, use Convert to invoice — lines and client info copy over with a new invoice number.

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.

Estimate 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 is the difference between an estimate and an invoice?

An estimate quotes expected work and price before the job; an invoice bills for completed work. Our estimate PDF uses the header ESTIMATE and includes a valid-until date and acceptance line.

Should I use estimate or quote on the PDF?

We use ESTIMATE on the PDF — it matches common search terms (e.g. "hvac estimate template"). The tool still works for informal quotes and proposals.

Does this cost anything?

No. Fill in the form and download the PDF. The site runs on ads.
