Jobber's 2024 survey found contractors spend an average of 45 minutes writing each estimate. At 20 estimates per month, that's 15 hours - nearly two full work days - spent on proposals instead of billable work.

AI estimating tools cut that time to under 10 minutes by automating the scope of work writing, material calculations, and professional formatting. Here are 7 options compared.

7. ChatGPT for Scope of Work

Not a dedicated estimating tool, but highly effective for generating scope of work descriptions from job notes.

Strengths: Free, flexible, handles any trade. Pair with your existing estimating spreadsheet or tool.

Best for: Contractors who want AI help with writing, not full estimating automation.

Same-Day Estimates Win More Jobs

Contractors who send same-day estimates close 20-30% more jobs than those who take 2-3 days. Speed signals professionalism and shows the customer you want their business.

An electrician on ContractorTalk shared that switching to AI-assisted estimates improved his close rate by 18% with no other changes to his pricing or sales process.

Good/Better/Best Pricing

Most AI estimating tools support tiered pricing - offering three options at different price points. Industry data shows good/better/best presentation increases average ticket by 15-25%. Most customers choose the middle option, which is typically priced higher than the single-option estimate would have been.

Where to Start

If you're using spreadsheets or handwritten estimates, any AI tool on this list is an upgrade. Start with Joist (free) or PandaDoc (free eSign) and commit to same-day estimates for 30 days. Measure your close rate before and after.

What the math looks like:

If you send 20 estimates/month at $3,000 average and close 30% (6 jobs = $18,000/month), improving close rate to 36% with same-day estimates = 7.2 jobs = $21,600/month. That's $3,600/month more from a free tool and a policy change.

Bad vs. Good estimate presentation:

Bad: Handwritten on a yellow pad: "Water heater replacement - $2,800. Parts and labor included. Call to schedule."

Good: Professional PDF from Joist: Company logo, customer name and address, detailed scope of work ("Remove and dispose of existing 40-gal gas water heater. Install new 50-gal Rheem ProTerra hybrid water heater. Replace supply lines, gas flex connector, and expansion tank. Update drain pan. Obtain city permit and schedule final inspection."), itemized pricing, three options (standard/energy-efficient/premium), warranty details, online payment link, and electronic signature.

What Not to Do

  • Don't delay estimates to calculate the "perfect" price. A 90%-accurate estimate sent today beats a 100%-accurate estimate sent Thursday. You can always adjust during the project if scope changes.
  • Don't give verbal estimates. They lead to disputes and make you look unprofessional. Even a quick Joist estimate on your phone is better than "it'll probably be around two grand."
  • Don't offer only one option. The good/better/best format works because it gives the customer control. One option forces a yes/no decision. Three options let them choose - and they usually pick the middle or top.
  • Don't skip the follow-up. If a customer hasn't responded to your estimate in 48 hours, send a reminder. Set up automated follow-up texts through your CRM. Most contractors lose jobs to the one who followed up, not the one with the best price.
  • Don't use the same template for residential and commercial estimates. Commercial clients expect more detail - material specifications, project timelines, payment schedules, insurance documentation. Use PandaDoc for commercial and Joist for residential.
