THE DETAILS
Writing estimates is one of the biggest time drains in any service business. You finish the job, then you have to go home and write about the job, price the job, format it, send it, and follow up on it. For a lot of small business owners that process takes hours every week.
AI has gotten genuinely good at this part. Here's what's actually worth looking at.
If You're In The Trades (HVAC, Plumbing, Electrical, Roofing)
These tools are built specifically for field service businesses. They handle scheduling, dispatch, and invoicing too, but the estimate and proposal features are what matter for this conversation.

Core plan: $69/month
Connect plan: $169/month
Grow plan: $349/month

If You're Not In The Trades
Not every small business uses field service software. If you run a cleaning company, a consulting practice, a small retail shop, or anything that doesn't fit the HVAC/plumber mold, these tools are worth looking at.
Jobber (still applies)
Jobber works for a wider range of service businesses beyond just trades. Landscaping, cleaning, pest control, and similar businesses use it effectively.
Bookipi
Best for: Freelancers, consultants, and small service businesses who need professional proposals fast without a monthly subscription.
What the AI does: You give it a project description and it generates a full proposal with problem statement, proposed solution, scope, and pricing structure. You edit and send.
Pricing:
Free to start, with core proposal creation included
Paid upgrade available for unlimited documents and advanced features
Pros:
Free tier is genuinely useful, not a bait and switch
Fast proposal generation from a simple prompt
Integrated with invoicing so the proposal can become a payment request
Good for businesses sending occasional proposals, not daily volume
Cons:
Interface has been described as clunky by some users
Export to Word for client redlining is difficult
AI is more of an assistant than a full generator on some features

The Honest Bottom Line
If you're in the trades and don't have field service software yet, start with Jobber's free trial. It will change how you run your business beyond just estimates.
If you're not in the trades and just need to write faster proposals, start with Bookipi or Hubflo. Both have free tiers that are worth testing before paying for anything.
The goal isn't to replace your judgment on pricing and scope. It's to get the paperwork out the door while the customer is still waiting by their phone.
