Invoice Goat is quoting and invoicing software for solo tradespeople and small service crews: electricians, plumbers, HVAC techs, landscapers, painters, pressure washers and cleaners. Send a quote from the job site and your customer signs it on their phone. Turn a signed quote into an invoice from the quote page. Your customer pays online by card or ACH, or you mark cash, check and Zelle payments yourself. Read receipts show when a quote or invoice is opened. Type a few rough notes and Invoice Goat writes a clean, professional quote or invoice from them. Keep customers, jobs and payments in one place, with a price book, a calendar, customer reminders, and revenue and year-end reports. It runs in any browser on a phone, tablet or computer, so there's nothing to download. One plan with every feature: $79 a month, or $69 a month billed yearly, with unlimited quotes, invoices and customers. Your first quote and invoice are free, with no credit card. Support comes straight from the founder, Jeff Burt.
