AI Software for Contractors: An Office Stack for a Five-Person Firm

Plan on $180 to $550 a month depending on how much you buy. A middle stack for five people is a job app with five users ($199 on Jobber Connect), an AI receptionist add-on (about $84 at 100 calls), a review-request tool ($75) and two assistant seats ($50): $408 a month on list prices, before payment fees and sales tax.

The cheapest stack isn't the stripped-down one; it is the one priced the way your firm works. Jobber charges by the user and ServiceM8 by the job, so five people doing 45 jobs a month pay $199 on Jobber Connect and $79 on ServiceM8 Growing for the same core scheduling and quoting work.

The monthly bill, line by line, for a five-person remodelling firm

The illustrative firm is an owner-estimator, an office coordinator and three installers. It sends 60 quotes a month, wins 25, and books another 20 repair calls directly, so 45 jobs. About 100 calls a month reach the receptionist (after hours and when the office is busy), and roughly 30 finished jobs a month should trigger a review request. Prices below are USD list prices read on 29 October 2026 from Jobber's pricing page and the other vendors' own pages, on monthly billing.

Three things to notice. The job app is under half the bill, so the add-ons decide whether the stack feels cheap. The receptionist line is a function of volume, not a flat fee. And the whole bill is small beside the payroll it supports, so the right test is the hours and jobs each line must earn back, which a table further down puts in numbers.

Over twelve months the standard stack comes to $4,899.60 on monthly billing, or $4,179.60 with Jobber prepaid for the year and the two ChatGPT seats on annual billing, a difference of $720. Jobber bills an annual plan in full at the start and the first payment is non-refundable, so I'd run the first quarter monthly and switch once usage is steady. Jobber also runs introductory discounts on the first months (in late October 2026 the page showed lower prices for the first three or twelve months on subscriptions started by 30 October), so check the page on the day you buy and budget the price that applies once the discount ends.

Why per-job pricing can beat per-user pricing for a small office

Jobber's Connect plan includes five users at $199 a month, and Housecall Pro's Essentials plan includes five at $149 a month on annual billing or $189 on monthly billing. ServiceM8 does the opposite: every paid plan has unlimited users, and the price steps with the number of new jobs per month. Its dollar price list shows Starter at $29 for 50 jobs, Growing at $79 for 150, Premium at $149 for 500 and Premium Plus at $349 for 1,500 or more, and its help text says each new job card uses one job credit, quotes included, with an accepted quote converting to a work order without using another. Running out doesn't halt work: the FAQ says you can keep creating jobs for another 7 days, after which you are prompted to upgrade unless the plan has reset.

For the illustrative firm that means 60 quote cards plus 20 direct jobs, or 80 credits a month. Starter's 50 would run out in the third week; Growing's 150 leaves room for 70 more cards, and it also holds ServiceM8's electronic forms, which the pricing page puts on Growing and above. The same people on Jobber cost $120 more each month. Whether that difference buys anything depends on features you will actually use, not on the headline price.

The inverse also holds. A firm with eight people and 400 small jobs a month would exceed Growing's 150 jobs and pay for Premium at $149, while Jobber's price would rise only with users. Count cards before you count staff. A fuller price-band comparison for estimating tools is in how much estimating software costs a small contractor.

Scheduling and quotes: what the AI inside the job app does

Both vendors now put AI in the quoting step. Jobber's pricing page lists a "Draft for me" button and automatic draft quotes from new requests, plus automatic follow-ups by email or text when a client has not replied. ServiceM8 lists an AI Writing Helper and AI Quote and Invoice on all plans, drafting a job description and its billing items, and an Office Agent Standard included from Starter up, with Office Agent Pro at $39 a month more for chasing quotes and flagging overdue tasks with approvals.

Whatever the product, check the output. Here is an illustrative case. The coordinator pastes in the estimator's site notes: "replace two fascia boards and soffit on rear extension, 6 m run, rot at corner, ladder access only, customer wants it paint-ready". The assistant returns a clean description with a line for each board, a day of labour and "all materials included, with a 10-year guarantee". Your terms offer no guarantee of that length, and the rot at the corner may widen once the board is off. The fix is a standing instruction ("never state a guarantee period; list exclusions for hidden damage") and a human read before sending. How to word those exclusions is the subject of five customer messages to draft with ChatGPT.

Quote follow-up is the quickest-payback feature in both products. ServiceM8 lists automated quote follow-up emails and texts on all plans, switched on under Settings and Automation, where you choose how many follow-ups to send, by email, text or both, and when. A sensible first setting for a firm that sends 60 quotes a month: an email on day three, a text on day seven and a final text on day fourteen. Suppose 35 of the 60 are still unanswered at day three. Each extra acceptance is worth about $1,200 of gross profit, and the follow-ups cost nothing beyond text allowances. I can't tell you the lift, so record your acceptance rate for 60 days before and after switching it on.

Now the sum that decides whether the quoting AI pays. If drafting saves 10 minutes on each of 60 quotes, that is 10 hours a month. At an assumed $25 an hour of office time, it is $250, more than the $199 Connect plan on its own. The 10 minutes is an assumption to test over a fortnight with a stopwatch, not a promise from any vendor.

Calls: the add-on, the overage and the one-job-a-year test

The receptionist is the only line that bills by use. Jobber's help page, updated 28 October 2026, says the add-on is $29 a month with 30 conversations, then $0.79 for each extra, and that it is included on the Plus plan with unlimited use. A call counts when the receptionist actively engages the caller, and a text thread counts once for up to 24 hours. At 100 conversations that is $29 plus 70 at $0.79, or $84.30; at 200 it is $163.30; at 40 it is only $36.90.

There is also a volume at which the plan upgrade wins. Connect plus the add-on costs about $204.30 plus $0.79 for every conversation, while Jobber Plus with five users is $499 on monthly billing with the receptionist included. The lines cross at roughly 370 conversations a month. Below that, buying Connect and the add-on is cheaper unless you want the other things Plus bundles; above it, check Plus before the overage runs away. If you would buy the Marketing Suite ($99) and Pipeline ($49) anyway, the crossing point drops to about 186 conversations, because Plus includes both.

Whether $84 is worth it comes down to one question: how many jobs does a missed call cost you? At an illustrative $1,200 gross profit per job, the receptionist covers its bill if it rescues one job every 14 months. The real number is higher, because the rescue rate depends on how many calls would otherwise go unanswered, which a week of your own call log will show. The choice between this add-on and a standalone service, with the sync and transfer details, is worked through in built in or standalone for a trades firm, and five vendors priced at a fixed 100 calls are compared in the 100-call answering-service tutorial.

Reviews: the free route and the $75 route

There are two ways to ask for reviews, and the free one works. ServiceM8 lists customer-feedback requests by email and text after a job on all plans, while Jobber's reviews tool sits in its Marketing Suite, a $99-a-month add-on that the Plus plan includes. Housecall Pro's pricing page lists review management among the features of every plan it shows, so a firm on that platform may not need a separate tool. A short text with your Google review link does the same job:

"Hi [first name], thanks for choosing [company]. If you were happy with the work, a short Google review helps other homeowners find us: [link]. If anything wasn't right, reply to this text and I'll sort it."

Google's rules bar incentives and selective asking, so send it to every customer, not only the happy ones, and never offer a discount for a review. A paid tool earns its place when the habit slips. NiceJob's pricing page lists Starter at $75 a month for review requests by text and email, with no contracts, and Pro at $125 adding AI replies to reviews. Whether $75 is justified depends on how many more reviews it brings than the free text does. Run the free text for a quarter, count the reviews it produces from your thirty or so finished jobs a month, and buy the tool only if requests stop going out or the count stalls. The marketing side of reviews is covered in AI marketing for contractors: reviews, case studies and local posts.

The assistant seats: who gets one and what for

Give the two seats to the two people who write the most. The estimator uses one for scope wording, supplier price summaries and bid clarifications. The coordinator uses the other for customer emails, schedule-change notices and invoice chasers. Installers don't need a seat; they need a phone and the job app. Put the shared instructions (your terms, exclusions, tone, what never to promise) into a Project so both seats start from the same rules, since OpenAI says project sharing works on every plan and Business adds group sharing.

A supplier price summary makes a good first test, because the usual mistake is easy to spot. The estimator pastes three quotes for a decking job and asks:

Compare these three supplier quotes for the same materials list.
Make a table: supplier, materials total, delivery, lead time, exclusions.
Flag anything that is not like-for-like. Do not round any number.
[paste quote A] [paste quote B] [paste quote C]

In an illustrative run, the answer ranked supplier B cheapest at $4,310, against $4,465 for A and $4,520 for C, with lead times of three, five and four working days. Read against the quotes, B's total left out a $185 delivery charge printed in its terms, while A and C included delivery, and B's boards were a thinner section than the specification. With delivery added, B is $4,495 and no longer cheapest, and the board difference makes it a different job. The fix is one line in the shared Project instructions ("include delivery and any charge in the small print; list every difference in specification") plus a habit: the estimator checks each summary against the source quotes before ordering.

Keep customer phone numbers and addresses out of prompts unless the task needs them. Business plans don't train on your content by default, which is one reason to prefer them over personal Plus accounts once staff handle customer details, but a prompt that never contained the address can never leak it.

Hidden costs that never reach the pricing page

• Payment processing. Jobber's pricing page lists 2.9% + 30¢ for card payments, 2.7% + 30¢ for Tap to Pay in the app and 1% for bank payments. On $40,000 of monthly card revenue, that is over $1,000 a month, more than double the software bill, and it exists in any stack that takes cards.
• Promotional prices that step up. Introductory prices for the first three or twelve months rise to the list price afterwards. Budget the steady-state number.
• Trial rules. Jobber's free trial is 14 days on the Grow plan, but its help page says add-ons cannot be bought during a trial, so the first month of the receptionist is paid, and add-on charges are non-refundable.
• Setup time. Importing customers, building a price list and writing templates takes the coordinator roughly 12 to 15 hours in month one, an estimate to adjust for your own records. At $25 an hour that is $300 to $375, once.
• Glue. A standalone receptionist feeding a job app usually needs a Zapier plan, from $19.99 a month billed annually for 750 tasks, or someone typing the details in.
• Sales tax and extras. The pages say prices exclude sales tax where it applies, and text messages, extra users and numbers can carry their own fees.

What each line has to earn back before it is worth keeping

Every line in the standard stack can be turned into a pass mark. Divide the monthly price by an office hour at an assumed $25, or by $1,200 of gross profit per job (both illustrative), and you have what must be true for the line to break even:

Sixteen hours a month across 60 quotes is about 16 minutes a quote, and 0.34 jobs is one extra job every three months. Neither bar is high, but neither is automatic. The job app clears its bar only if quotes, schedules and invoices all run through it. The receptionist clears it only if after-hours enquiries become booked work. The review tool clears it only if requests actually go out. That is why the order below matters: you can check one line at a time.

Three price levels: lean, standard and one-vendor

The standard stack costs $230.30 more than the lean one. To justify that, it needs to save about 9.2 hours of office time at $25 an hour, or win 0.19 extra jobs at $1,200 profit, roughly one every five months. If the firm already lives in Jobber and wants the receptionist inside it, the premium is easy to defend. If it is starting from nothing, the lean stack is the better first purchase, and you can step up once the numbers justify it.

The one-vendor stack is a different bet: it makes sense when you value having the receptionist, Pipeline and the Marketing Suite in one account more than the $141 a month it adds over Standard. Bought one at a time on Connect, those three add-ons cost $99 for the Marketing Suite, $49 for Pipeline and $84.30 for the receptionist at 100 conversations, so $431.30 a month with the plan; Plus at $499 costs $67.70 more and makes the receptionist unlimited. If the firm's email already runs on Google Workspace or Microsoft 365 Business, test the assistants bundled with those plans before buying ChatGPT seats; the Workspace tier includes Gemini and the Microsoft plans include Copilot Chat. The wider question of which tools to buy first and which to skip is in which AI tools a general contractor should buy and what to skip.

Buy in this order, and check each purchase after two weeks

1. Week one, the job app. Import customers, load your price list, write three quote templates. Check after two weeks that every new enquiry exists as a request or job card, with no sticky notes left.
2. Week two, the receptionist on after-hours calls only. Run ten test calls. Check that transfers reach a person and no booking lands outside your capacity.
3. Week three, review requests. Switch on the free text or the paid tool. Check that every finished job triggered a request.
4. Week four, the assistant seats. Give the estimator and the coordinator the same standing instructions. Check that each has used it on five real tasks and that nothing went out unread.

After a month, sort each line into keep, change or drop using the question each one was bought to answer: did calls stop going missing, did quotes go out faster, did reviews arrive, did the office stop typing the same thing twice? If you can't answer yes with a number, don't renew that line.

Questions about pricing a contractor's office stack

Do these prices include sales tax?

No. Jobber's pricing page says subscription prices exclude sales tax where applicable, and Housecall Pro's page lists USD prices excluding sales tax. Card-processing fees, text charges and extra users sit on top as well, so check your first invoice against the page.

Is annual billing worth it for a five-person firm?

Only after the receptionist and quoting features have proved themselves. Jobber bills annual plans in full up front and the first payment is non-refundable. Connect with five users is $149 a month prepaid, $169 on a one-year commitment billed monthly and $199 with no commitment. Start monthly, then switch once usage is steady.

What if we grow beyond five people?

Jobber's pricing page shows larger user tiers, with Connect at $299 a month for ten users and $399 for fifteen on monthly billing. ServiceM8 has no per-user fee on paid plans and prices by jobs per month instead, so check which side your growth lands on before choosing.

Do we need ChatGPT Business, or is Plus enough?

Plus costs $20 a month per person for individuals. Business seats are $25 monthly or $20 on annual billing with a two-seat minimum, and business content is not used for training by default. For two people the totals are $40 against $50 monthly, so the gap is small when staff handle customer details.
