Use AI to review your draft invoice before sending to spot missing charges and unclear descriptions that cost you money.
You finish a job, rush to write the invoice, and hit send. Later you realize you forgot to charge for extra fittings, didn't include the emergency callout fee, or described the work so vaguely the customer questions it. Those mistakes cost you real money and credibility. Before you send any invoice, paste it into ChatGPT and ask it to review for missing charges, unclear line items, and potential customer confusion. The AI will flag vague descriptions like 'misc materials' that invite pushback, spot labor hours that don't match the work described, and remind you of common charges you might've forgotten. It takes 60 seconds and catches the costly mistakes you miss when you're tired after a long job. Think of it as having a business-minded colleague review every invoice before it goes out—except this colleague never gets tired and remembers every detail you tell it about the job.
