Buy in this order: a chat assistant (about $20 a month), an AI receptionist for missed calls ($0 to $150), a photo app like CompanyCam (from $63), then project software with AI included, such as JobTread ($199 plus $20 per extra user). Skip AI takeoff, contract review and scheduling AI until your costs and contracts are standardised.
What changes the order is firm size and how many jobs run at once. A two-person firm with one live job needs the first two items and a free plan viewer. A ten-person firm with eight live jobs is losing money on paper, photos and rework, and should buy the third and fourth. Be most wary of anything that promises to automate a process you have not written down yet. Prices below are list prices in dollars, read from the vendors' own pages in late October 2026.
One purchase rule a six-person firm can apply in ten minutes
The rule has three parts. The task must recur every week or month, so you can see the saving. It must be countable today, in minutes or in missed calls, so you have a baseline. And a person must still review the output, because every tool below makes mistakes. If a purchase fails any one of the three, wait.
Then do the arithmetic that sellers do not do for you. Divide the monthly price by what an hour of the person who will use it costs you, and you get the hours the tool must save before it pays. At a loaded cost of $50 an hour for office time (an assumption; use your own), the sums look like this.
| Tool | Monthly price | Hours it must save | Where the hours come from |
|---|---|---|---|
| Chat assistant, one seat | $20 | 0.4 | Emails, change-order wording, minutes |
| Meeting notes (Otter Pro, annual billing) | $8.33 | 0.17, about ten minutes | Writing up each site or client meeting |
| Photo app (CompanyCam Crew) | $129 | 2.6 | Hunting for photos, building progress reports |
| Project software (JobTread, four internal users) | $259 | 5.2 | Re-keying estimates, chasing selections and logs |
| AI takeoff (Kreo Pro, one user) | $175 | 3.5 | Counting and measuring plans |
| Receptionist (Quo seat plus Sona, 100 calls) | $72 | Not hours | Revenue: enquiries you would otherwise miss |
Most of those pass easily on paper. The takeoff tool is the one whose saving depends on a condition you may not meet, which is why it sits on the skip list below. Receptionists are different in kind: their value is revenue from calls that would have gone to voicemail, so count the calls you miss for two weeks before deciding.
Decision rule by firm size
Size is a proxy for two things that matter more: how many jobs are live at once, and how many people touch each job's paperwork. The table puts the first purchases in the order I would make them. The spend figures use the prices read for this tutorial and are monthly.
| Firm | Buy now | Buy when this happens | Skip for now |
|---|---|---|---|
| One to three people, one to three live jobs | Chat assistant ($20); receptionist paid per call ($0 to $45); Fieldwire Basic for plans, tasks and photos ($0, up to 5 users and 3 projects) | You run more than three jobs at once, or a second person starts writing estimates | Project software, takeoff, contract review |
| Four to ten people, four to ten live jobs | Everything above, plus project software with AI built in (JobTread from $199 plus $20 per extra user) and a photo app (CompanyCam from $63) | You bid more than a few jobs a month from drawings and have standard cost codes | Standalone takeoff, contract review, scheduling AI |
| Eleven to thirty people | Project software for everyone who touches estimates, logs and selections; a photo app for field leads; a receptionist on a flat plan | Drawings dominate bidding (takeoff); you review many non-standard contracts (contract review) | A second assistant subscription; agency-built AI lead tools |
For the companion piece on which site and office apps do what, see the comparison of site and office AI apps for general contractors. The question here is order and restraint, not features.
First: a chat assistant, and one change-order notice done properly
ChatGPT lists Plus at $20 a month, and Claude lists Pro at $17 billed annually or $20 monthly. Both providers also sell business seats, at $20 a seat on annual billing and $25 monthly with a two-seat minimum. Their terms bar sharing a login, so give each person who uses one a seat of their own. It earns its place fastest on writing: emails to clients, sub follow-ups, schedule narratives, minutes. It is also the tool you will use to check the others, so learn it first.
Here is a task that suits it and shows how to keep it honest. A subcontractor has missed two start dates, and you need a firm written notice that does not pick a fight. Paste in the relevant contract text yourself, because the assistant must not guess at it.
Draft a firm but civil notice to a subcontractor who has missed two agreed start dates (the 3rd and the 10th). Use only the clause text I paste below for any contractual reference; do not cite clause numbers or remedies that are not in that text. Ask for a confirmed start date within 48 hours. Do not threaten termination. Keep it to 150 words.
Clause text: [paste the relevant paragraph from your subcontract]Subject: Confirmation of start date, [project]
Hi [first name],
We agreed start dates of the 3rd and the 10th, and neither was met. The programme is now affected on [task]. Under the subcontract, [quote from pasted clause]. Please confirm a firm start date in writing within 48 hours so we can reset the sequence. If there is an obstacle on our side, tell us what it is and we will deal with it.
Regards,
[your name]Check the output for three things. It should quote only what you pasted, and any clause number it adds on its own is invented. It should not stray into threats or legal conclusions, such as declaring a breach, which belong with your lawyer. And the dates and task names must match your records. Treat the draft as a first pass you would be willing to sign, not a final one.
A second job it does well is the weekly client update, where the raw material is a messy list of site notes. Ask for three headings only: done this week, next week, and decisions we need from you. Here is a before and after.
Before (site notes): framing signed off Tue; 2 joists notched for waste pipe, need sistering, +1 day; electrician slipped to Mon; window delivery Thu or maybe 2 wks, supplier unclear; client to pick tiles by the 14th
After: Done this week: framing signed off. Two joists needed strengthening where a waste pipe passes through, adding one day. Next week: the electrician starts on Monday. Windows are due on Thursday, though the supplier has not confirmed. Decisions needed: please choose the bathroom tiles by the 14th so we can order in time.The assistant has tidied the language, but you still own the facts. "Maybe two weeks" has become "has not confirmed", which is accurate; had it written "windows arrive Thursday", it would have promised something the notes never said. Read for exactly that kind of slip every time.
A third job, and one that can pay for the seat on its own, is levelling subcontractor quotes before you choose one. Paste two or three quotes for the same package and ask for a like-for-like table. Here is a prompt and a sample answer, with made-up prices.
Compare these three electrical subcontractor quotes for the same kitchen extension. Make a table with one row per item, showing what each quote includes, excludes or does not mention. Use only the quote text I paste. Do not judge quality or recommend a firm. Under GAPS TO ASK ABOUT, list every item that appears in one quote but not the others.
Quote A: [paste]
Quote B: [paste]
Quote C: [paste]Item | A | B | C
Electrical panel upgrade | Included | Not mentioned | Excluded
Downlights (12) | Included | Included | Included, fittings by client
Making good after chasing | Excluded | Not mentioned | Included
Testing and certificate | Included | Included | Not mentioned
Price | $6,850 | $5,900 | $6,400
GAPS TO ASK ABOUT: B on the panel and making good; C on testing and the certificate; who supplies the light fittings.In this example the cheapest quote is also the one with the most gaps, which is the pattern the table is there to catch. What to fix: check every cell against the paper quote, because a model will sometimes read "by others" as "included", and never let the table stand in for the quote itself when you place the order.
For meetings, a transcription tool costs less than most lunches: Otter lists a free Basic plan with 300 transcription minutes a month, capped at 30 minutes per conversation, and Pro at $8.33 a month billed annually or $16.99 monthly. The cap matters more than the monthly total: a 45-minute design meeting with a client stops being transcribed two-thirds of the way through on the free plan, so pay for Pro once meetings regularly run past half an hour. Ask everyone in the meeting before you record it, and read the minutes against your own notes the first few times.
Second: answering the calls a contractor misses
A general contractor's phone brings in more than leads. Subs ring about start times, suppliers about deliveries, inspectors about access, and homeowners about projects. A receptionist must sort these. Some project software has a call add-on, such as Jobber's Receptionist at $29 for 30 conversations or Roofr's for roofing at $99, but JobTread's AI page lists ten tools and none of them answers a phone. Most general contractors will go standalone, and the cost is per call.
| Route | 30 calls | 100 calls | 250 calls |
|---|---|---|---|
| Smith.ai AI Receptionist | $15 (Free: 25 calls, then $3) | $212.50 (Pro 75-call tier at $150 plus 25 extra at $2.50) | $500 (300-call tier) |
| Quo seat plus Sona | $35 (Starter seat $15; Sona's free tier, 10 calls then 20 at $1) | $72 (Business seat $23, Sona $49) | $122 (Business seat $23, Sona $99) |
Quo seats are shown at their yearly-billing rates; month to month they cost $19 for Starter and $33 for Business. The Quo route is cheaper on paper but needs Quo as your phone system, and call transfers to a person start on its Business plan, so the $35 Starter figure suits only a firm that is happy to take messages rather than transfers. The Smith.ai route needs only call forwarding. The 100-call comparison across five vendors prices more options, and the sibling on receptionist costs and call routing for construction companies covers how to sort callers.
The intake that matters for a general contractor is short. Ask what the project is, the rough scope, the property type, whether plans exist, the timeline, a budget range, and the best number to text. Sub and supplier calls go straight to the project manager. A good enquiry summary looks like this.
NEW ENQUIRY - HOMEOWNER
Project: single-storey rear extension and kitchen reconfiguration
Plans: architect's drawings exist, planning status unknown
Budget range given: $180,000 to $220,000
Timeline: wants to start in spring
Property: detached house, owner-occupier
Contact: [first name], mobile [number], OK to text
Next step: site visit offered, Thursday or Friday afternoon (from calendar)Do the sum on one recovered lead. If you miss ten enquiry calls a month, one in ten of those would have become a project, and your gross profit on an average project is $9,000 (an assumption), that is $9,000 you could have booked against a plan that costs $72 a month. Replace the figures with your own, and note that the real risk lies in how the assistant handles calls, not in its price.
Third: photos, and the CompanyCam plan that does not add up
Photo documentation settles disputes and speeds up change orders, which makes it one of the cheaper forms of protection a contractor can buy. CompanyCam's pricing page lists Core at $63 a month with one user included (up to two), Crew at $129 and Scale at $199 with three users each, and extra users at $29. Those are the per-month figures on annual billing, which the page says saves 20%, so month-to-month costs more; the page text I could read did not show the monthly prices, and its help centre has shown different Crew and Scale figures, so confirm at checkout. Each plan has a free trial of an unstated length.
The AI element is where the page contradicts itself. Its comparison table shows 10 AI credits on Core, 100 on Crew and unlimited on Scale, while its FAQ says AI features are included in Crew, Scale and Enterprise. Both statements are on the same page. I would take the more cautious reading, that Core may not include the AI, and ask support to confirm in writing before you buy Core for that reason. The plan names AI Walkthrough, AI Powered Documents and AI Checklists in its comparison table, but the table does not show which plans get which.
You do not need a paid photo app to start. Fieldwire's Basic plan costs nothing and covers plan viewing, tasks, files and photos for up to five users, three projects and 100 drawing sheets, and its paid plans run from $39 a user a month, billed annually, with RFIs, submittals and change orders on Business Plus at $89. The sheet limit is the one to watch: three small residential sets fit easily, but one large set of drawings can use most of it on its own. If a free tool is working, the question for a paid one is what it saves in hours, using the table above.
Fourth: project software with the AI already inside
JobTread lists a single price on its pricing page: $199 a month with one internal user included, plus $20 a month for each extra internal user from the second to the tenth, $15 from the eleventh to the twentieth, then $10 and $5. It offers 20% off annual plans, no free trial, because every client is assigned a customer success manager, and a 30-day money-back guarantee on monthly plans. Everything is included, with no tiers. Customer and vendor portal users are free, and some field crew who only upload photos, log notes or view schedules can be free users too.
Its AI page lists ten built-in tools: AI Estimating for draft budgets, a form builder, plan import and count tools that name, number and scale plan sheets, daily-log summaries, a formula builder, a writing assistant, an autofill for the web clipper, receipt scanning, a support assistant and a report builder. It also lists an AI Connector that links outside tools such as ChatGPT or Claude to JobTread through an MCP server (a standard way for an assistant to read data from another app). The page does not say whether that needs a paid assistant plan or your own API key, so check before you count on it. No AI tool carries a separate charge on the page, and the pricing page says all features are included.
The sum for a six-person firm with four internal users is $199 plus three at $20, so $259 a month, or roughly $207 if you take the 20% annual discount. That one line carries estimating, scheduling, a client portal and the AI tools, which is why I put project software ahead of standalone AI add-ons: the plan-count and draft-budget tools give you a taste of AI takeoff without a second subscription. A more detailed cost view is in JobTread pricing for a five-person builder.
Buildertrend is the obvious alternative, but its pricing page returned an error when I tried to read it, so I have not quoted a figure; get a written quote and compare it line by line.
What to skip until the basics are in place
- Standalone AI takeoff. Kreo's Essential plan, at $100 a user a month billed annually, is "without AI". The Pro plan, at $175, adds AI takeoff for rooms, walls, doors and windows, and Business is $250 a seat with a five-seat minimum, $15,000 a year. All are annual, with a seven-day trial. Skip it until you bid several jobs a month from drawings and have a cost database for the quantities to feed. Then test it on three past plans where you know the final quantities. The tutorial on testing AI takeoff on drawings sets out how.
- Contract review software. Document Crunch calls itself an "AI Risk Intelligence Platform Built for Construction", publishes no price and offers a free trial. The firms shown on its home page are mostly large contractors. A small firm can use an assistant for a first read and a lawyer for the rest. Before any demo, read the ten questions to ask in a contract software demo.
- Scheduling and delay-prediction AI. A prediction is only as good as the schedule it learns from. Keep the live schedule in your project software for a quarter before buying anything that predicts it.
- Agency-built AI lead tools and website chatbots. They add a fee on top of a receptionist that already takes the calls.
- A second assistant subscription. It earns nothing until the first is used daily.
A bad purchase, and how it showed up
Consider a purchase that failed the rule. A ten-person remodelling firm bought AI takeoff at $175 a month because its estimator was behind. The tool produced quantities in minutes, but the firm had no standard cost codes, so every output had to be mapped by hand to the estimate lines. Six months later it had spent $1,050, and the estimator was still doing takeoff manually on anything above a simple job. How it showed up was in the monthly review: nobody could name a single estimate that had used the tool's numbers unchanged. The fix was to define 40 standard cost codes and assemblies first, then re-trial on three old jobs. Only then did the tool's output stop needing a translation step.
What a six-person remodelling firm pays each month
Take a six-person remodelling firm with four internal users, four live jobs and about 100 calls a month, roughly 30 of which it cannot answer. The bare-minimum set is a $20 chat assistant, the Smith.ai Free plan covering only those 30 overflow calls at $15, and Fieldwire Basic at $0: $35 a month. The everything set puts all 100 calls through the Quo receptionist at $72 and adds JobTread at $259, CompanyCam Crew with one extra user at $158, two chat seats at $40 and Otter Pro at $8.33: $537.33 a month. A working set between the two, JobTread plus two chat seats and the Quo receptionist, is $371.
| Line | Bare minimum | Working set | Everything |
|---|---|---|---|
| Chat assistant | $20 (one seat) | $40 (two seats) | $40 |
| Calls | $15 | $72 | $72 |
| Photos and plans | $0 (Fieldwire Basic) | Included in JobTread's own tools | $158 (CompanyCam Crew plus one user) |
| Project software | None | $259 | $259 |
| Meeting notes | None | None | $8.33 |
| Monthly total | $35 | $371 | $537.33 |
The working set drops the photo app because JobTread takes job photos itself, and its pricing page lets field crew who only upload photos, log daily notes or view schedules join as free users. That is why the photo app, third in the buying order for a firm without project software, becomes optional once JobTread is in. I would start with the bare minimum for a month, move to the working set when a fifth job goes live, and add the photo app only when a photo dispute or a change order proves the need. The difference between $371 and $537.33 is $166.33 a month, which at $50 an hour is 3.3 hours of office time. If the photo app does not save that, it should not stay.
Day 60: keep, change or cancel
Set the review date when you buy. Write down one metric and one baseline for each tool, and decide the pass mark now, not when you are attached to the tool. Here is a filled-in version for a made-up firm.
| Tool | Metric | Baseline | Day 60 | Decision |
|---|---|---|---|---|
| Receptionist | Enquiry calls answered or returned within an hour | 6 of 14 | 13 of 15 | Keep |
| Chat assistant | Minutes to write a weekly client update | 45 | 20 | Keep |
| Photo app | Minutes to find the photos for a change order | 25 | 22 | Cancel, or move to the free tool |
| Project software | Estimates built without re-keying | 0 of 5 | 4 of 6 | Keep |
The photo app is the one that fails here, and that is the point of writing the number down before you start. Cancelling a tool that did not move its number in 60 days is the plan working, not a failure. If you would rather map this against your own jobs with someone, that is what my AI implementation consultation covers, at the contact page.
Questions general contractors ask before buying AI tools
Is JobTread's AI included in the price or an add-on?
JobTread's pricing page says all features are included, with no upgraded tiers, and its AI page lists tools such as AI estimating, a form builder, plan import and counting, daily-log summaries, a writing assistant and receipt scanning without naming a separate charge. The price is $199 a month plus $20 for each extra internal user, with no free trial but a 30-day money-back guarantee on monthly plans.
Does CompanyCam's Core plan include AI?
Its pricing page conflicts with itself. The comparison table shows 10 AI credits on Core, 100 on Crew and unlimited on Scale, while the FAQ says AI features are included in Crew, Scale and Enterprise. Billed annually, Core is $63 a month with one user included (two at most), Crew $129 and Scale $199 with three users each, and extra users are $29. Ask support in writing before buying Core for the AI.
Can a chat assistant replace contract review software?
For a first read, partly. It can summarise a contract, list payment and notice terms and flag clauses to ask about. It cannot give legal advice or know the rules that apply to you. Treat its output as a reading aid, check every point against the document, and use a lawyer for anything you might sign or enforce. Dedicated tools such as Document Crunch publish no price, so ask for the free trial first.
How do I know whether an AI receptionist is worth it?
Count the enquiry calls you miss over two weeks, then divide the plan's monthly cost by your gross profit on an average job. At $72 a month and an assumed $9,000 of gross profit, one recovered project covers about ten years of the plan. The real risk is not cost but poor handling of the calls it does answer, so test it with rehearsal calls first.
