A completed roofing job is one of the most satisfying moments in any trade. Don't let it slip into a week-long invoicing delay. BIG INVOICE lets you create a detailed, professional invoice on the roof — or in the driveway — before you've packed up the truck. Client has a PDF in their inbox before you've hit the highway.
Roofing estimates involve materials, labor, disposal, and contingencies. BIG INVOICE lets you pre-save your standard line items — square footage pricing, underlayment, flashing, labor rates — and build detailed estimates in minutes. Send to the client for approval, then convert to invoice when the job is done.
Most roofing jobs involve a deposit up front and a final payment on completion. BIG INVOICE handles partial payments cleanly — record the deposit, track what's outstanding, and invoice the remainder when the job closes. No separate spreadsheet, no mental math.
A $15,000 roof replacement needs a professional invoice — not a handwritten note. BIG INVOICE produces clean, branded PDFs with your business name, itemized line items, payment terms, and contact details. Looks professional to homeowners and insurance adjusters alike.
