The four paper forms every small contractor reaches for, as clean print-ready PDFs, plus a spreadsheet to track them: Invoice, Estimate/Quote, Change Order, and Payment Receipt — each with business/customer blocks, 8 line items, subtotal/tax/total, and a signature line — and an Excel Invoice & Estimate Log (with an example row) that also opens in Google Sheets. Print them, fill them in by hand or from any PDF reader, and log the job in the spreadsheet. Made for 1–5-truck HVAC, plumbing, electrical, and handyman shops that don’t want a subscription invoicing app. Honest scope: these are blank business forms — not legal contracts, tax documents, or accounting advice — and they don’t calculate totals automatically; the log spreadsheet tracks what you enter. FAQ — Can I add my logo? PDFs are clean unbranded forms; add your business name at the top; logo-stamped versions aren’t included. Do the forms auto-total? No — print-ready forms; the Excel log records amounts. What software do I need? Any PDF reader + Excel or Google Sheets.
