What a contractor invoice needs to include

An invoice that gets paid fast answers every question before the customer asks it: who did the work (your business name, phone, and license number where your state requires it on paperwork), where and when (service address, date, an invoice number for both your records), exactly what was done (itemized parts with quantities and prices, labor as its own line), what's owed (subtotal, tax, total due), and how to pay (check, card, payment link, spelled out in the notes). For HVAC and appliance work, add the equipment's model and serial number to the description line: it settles warranty questions before they become phone calls.

Pricing the job right

The most common invoicing mistake in the trades isn't formatting. It's giving away the truck roll. If you're not sure your service call fee actually covers your drive time, fuel, and overhead, run your numbers through our free service call fee calculator before you send the next invoice.

The honest pitch (feel free to ignore it)

This generator is genuinely free and we're happy if it's all you ever need. But if you're typing invoices on a phone keyboard in a driveway more than a couple of times a week, there's a faster way: with FieldForge you just say the job, "replaced the capacitor and two pounds of R-410A, three hours labor", and the invoice builds itself from your own price book, in English or Spanish, and texts itself to the customer with a payment link. It starts free (15 invoices a month), takes about two minutes to set up, and this page will still be here if you'd rather keep typing.

Quick answers

Is this invoice generator really free?

Yes, no signup, no watermark, no trial clock. It runs entirely in your browser; nothing you type is sent to any server.

How do I save the invoice as a PDF?

Click Print / Save PDF, then choose "Save as PDF" as the destination in the print dialog. On iPhone and Android the share/print menu offers the same option.

Do I charge sales tax on labor?

Depends on your state: some tax parts only, some tax labor too, and repair vs. new-construction rules differ. Set any rate you need here, and confirm what applies with your state's department of revenue or your accountant.

Can I use this for estimates too?

Sure, put "ESTIMATE" and a number like EST-101 in the invoice # field and note "This is an estimate, not a bill" in the notes. (FieldForge does spoken estimates with one-tap customer approval, if that becomes a habit.)
