Writing and marketing copy: pay a little, skip the suite
For emails, texts, job postings, and social captions, a general chatbot does the job. ChatGPT's free tier and the paid Plus tier (about $20 a month as of mid-2026) both write fine contractor copy once you give them your business details and a rough draft to react to. Claude works the same way and tends to write less like a robot out of the box, which matters when you're pasting its output straight into a text to a customer.
Skip the AI-only 'content suites' built for marketing agencies: expensive monthly plans that promise blog calendars and social schedulers you'll never touch. You're one person running a trade business, not a content team. A $20 chatbot subscription plus 20 minutes a week beats a $200 suite you log into twice.
The one thing worth paying a little more for is a tool that remembers your business facts between chats, so you're not re-explaining your service area and pricing every time. ChatGPT Plus and Claude Pro both have a memory or 'project' feature for this. Set it up once: paste your services, cities, licensing, and tone, and every future draft starts from that instead of a blank page.
Phones: the free tier is not enough, this is worth paying for
This is the one category where free genuinely falls short. A missed call from a real customer costs you the job, not a minor inconvenience, and no free tool reliably catches it. See the guide on missed-call text-back at /guides/missed-call-text-back for the full setup, but the short version: a business phone app with auto-reply built in (OpenPhone runs around $15 a month) texts back anyone who hits your voicemail within a minute, and that alone recovers jobs a free voicemail greeting never will.
Full AI voice receptionists that answer calls, hold a conversation, and book onto your calendar run roughly $30-150 a month depending on the tool. Worth it once you're missing more than a handful of real customer calls a month while you're on a job or asleep. Not worth it if you already answer nearly everything yourself. Run your own numbers on that decision at /guides/ai-receptionist-basics before you buy.
Skip: human answering services billed per call or per minute. They cost more than AI options as your call volume grows, and the operator is reading from a script about a trade they don't do. Fine as a stopgap, bad as a long-term line item.
Scheduling and dispatch: use what's already in your FSM
If you run Jobber, Housecall Pro, or ServiceTitan, don't buy a separate AI scheduling tool. All three have been building AI features (smart dispatch suggestions, automated reminder texts, follow-up sequences) directly into the platform you already pay for. Check your settings or the app marketplace inside your existing tool before adding anything new.
If you're still running paper or a shared calendar, the AI layer isn't your first move. Get a real field service app in place first (Jobber and Housecall Pro both start free or under $50 a month for a solo operator), then turn on its automated reminders and follow-ups once you're comfortable with the basics. Buying AI scheduling before you have basic scheduling is backwards.
The one AI habit worth building regardless of your platform: automated estimate follow-up. Unsold estimates that never get a second touch just die quietly. A simple automated check-in at day 2, day 5, and day 14 closes noticeably more of them, and it's usually a toggle inside your existing FSM, not a new subscription.
Books and admin: free tools cover almost everyone
QuickBooks and Wave both now bake AI-assisted transaction categorization into their standard plans, meaning the software guesses which expenses go where and gets better as you correct it. If you're already paying for QuickBooks (plans run roughly $35-90 a month depending on tier), you already have this. Wave is free for basic bookkeeping and invoicing, and is genuinely enough for a one or two truck operation with simple books.
Receipt scanning is the other place AI quietly helps: photograph a receipt in the QuickBooks or Wave app and it reads the vendor, date, and amount for you instead of manual entry. That's included, not an upsell.
Skip: standalone 'AI bookkeeper' apps that promise to replace your accountant for $50-100 a month. They're fine at categorizing but bad at the judgment calls that actually save you money at tax time (what's deductible, how to handle a vehicle purchase, quarterly estimates). Keep a real accountant or bookkeeper for that and let the free or already-paid-for tools handle data entry.
The one thing to buy first if you buy nothing else
If you're picking one category to spend money on this year, make it phones. A missed call from a real customer is the most expensive kind of miss a service business has: they're actively looking to hire someone right now, and if you don't answer, the next name on the search results does. Writing and books have solid free options; a missed customer call does not.
Don't try to add all four categories at once. Pick the one costing you the most right now, get it running, and confirm it's actually paying for itself before you add the next one. A business running one AI tool well beats one running four badly.
Quick gut check: pull your last 30 days of missed calls. If more than a few were real customers, start with phones. If your calls are mostly covered but you're drowning in follow-up texts and unsold estimates, start with scheduling instead.
