Contra's freelancer rate guide puts a simple automation at $500 to $1,500 and a complex multi-step build, which is what calls, quotes, follow-ups and reviews together amount to, at $2,000 to $10,000 or more, with retainers of $1,000 to $5,000 a month, all before your own software fees. A fair package also includes testing, handover and accounts in your name.
Those bands are wide because the word "package" hides very different scopes. One small agency's plumbing page lists an entry tier at $197 a month plus a $297 setup fee, with no AI call answering, and a full build from $2,500. Clutch's AI pricing guide, updated in September 2026, covers software development firms rather than trades, and shows reviewed projects from $10,000 to $49,999. A plumber should line up what each quote includes before comparing the totals.
The way to judge a quote is bottom-up: price each job the package performs, add your own software fees, and compare with what doing it yourself would cost. Vendor prices below were read from their own pages in October 2026. The setup hours are my planning estimates, and every business in the examples is imaginary.
What the published price bands say, and what they leave out
Contra's page for hiring Zapier automation freelancers says specialists typically charge $30 to $150 an hour, with entry-level people at $30 to $50 and experienced ones at $100 to $150. It puts simple automations connecting two or three apps at $500 to $1,500, complex multi-step workflows at $2,000 to $10,000 or more, and retainers at $1,000 to $5,000 a month. That is a freelancer marketplace, but the work it describes is close to what a plumbing package contains: connecting a phone line, a field-service tool and a messaging step.
The small agency page mentioned above gives a useful picture of the low end. Its $197 a month tier, with the $297 setup paid before the build starts, lists missed-call text-back within 60 seconds, a seven-day automated follow-up sequence, a chatbot added to your existing website, review-request automation and a monthly check-in call, plus a 30-day satisfaction guarantee whose terms the page does not give. A $397 tier, with $497 setup, adds an AI receptionist that handles inbound calls, email and text campaigns and online booking, and a three-week pilot costs $297 flat. Neither tier states a contract length, and the page says nothing about who owns the accounts and phone numbers. Treat these as one small provider's asking prices, not market averages.
For the calls part alone, one vendor sells a done-for-you tier of its own. Smith.ai's AI Receptionist has a free plan with 25 calls a month and $3 for each call after that. Its Pro plan starts at $150 a month for 75 calls, and its Enterprise plan starts at $500 a month for 300 calls and adds full-service setup, ongoing optimisation and custom prompting. The page says it is month-to-month with no long-term contract. That is a useful yardstick: if an agency quotes $500 a month for call answering alone, you can ask what it adds beyond that.
The four jobs a plumbing package covers, and the DIY price of each
A plumbing package usually promises four things. Here is what each is, what it costs if you do it yourself on vendor list prices, and what a provider should add.
Calls
Jobber sells its AI Receptionist as a $29-a-month add-on on selected plans and includes it on its Plus plan, describing 24/7 service over call or text that answers questions and books jobs into your calendar, with controls over what it can and cannot do. The pricing page shows no limit, but Jobber's help article (updated 28 October 2026) says the $29 covers 30 conversations a month, with $0.79 for each one after that, and that Plus includes unlimited use. A call counts once the assistant actually engages the caller, so spam and silent calls are free, and a text conversation stays open for up to 24 hours. At 80 conversations a month the add-on costs $29 plus 50 at $0.79, or $68.50. An admin can pause it at the limit instead, which means later callers get no answer from it. Smith.ai's tiers above are another route. A provider adds the call flow, the number set-up, a routing rule for emergencies and the testing. Ask how many calls or conversations are included and what happens beyond that.
Quotes
The quote itself should come from your own price book. Jobber's quote tools start on its Core plan, at $29 a month on annual billing after the first year or $49 a month paid monthly. AI helps with the wording of line descriptions and with checking a quote for missing items. A provider adds the price book load, quote templates for the common jobs such as water heaters and repipes, and an approval rule, for example that anything over a set value goes to the owner first. A flat-rate price list built with AI shows what the price book should hold.
Follow-ups
On Jobber, automated quote and invoice follow-ups arrive with the Connect plan ($99 a month for one user on annual billing after year one, $139 monthly) and custom workflow automations with Grow. A general automation tool such as Zapier has a free tier of 100 tasks a month, and its Professional plan is $19.99 a month on annual billing for 750 tasks. A provider adds the sequences, the stop rules (the messages must stop when the customer replies or books) and the quiet hours and opt-out wording for texts. A realistic slip is a sequence with no stop rule: a customer books on day two and still receives the day-five and day-nine messages asking whether they are ready to book. It shows up as a puzzled phone call or an unkind review, and the fix is a stop condition tied to the booking status.
Reviews
Most field-service tools can send a review link after a job is marked complete, and your own phone can do it for free. A provider adds the flow, and the flow must follow Google's rules: no incentives, no asking only the customers you expect to be happy, and, since April 2026, no asking for reviews that mention specific content such as a technician's name. A package that promises "more five-star reviews" is promising something it cannot control, and may be tempted to bend the rules to deliver it.
The inclusion list to hold every quote against
Price comes second to scope. Use this list as a filter: ask each provider to mark every row "included", "extra, at this price" or "not offered", and ask for the evidence in the last column before you pay.
| Area | What should be included | Evidence to ask for |
|---|---|---|
| Discovery | A written brief listing your services, areas, hours, price book and emergency rules | The brief they produced |
| Call handling | Script, number set-up, spam handling, emergency rule, transfer to a person | A recorded demo call to your own number |
| Quotes | Price book loaded, templates for your top five jobs, approval rule | A sample quote built from your prices |
| Follow-ups | Sequences with stop rules, quiet hours and opt-out wording | The message text and the stop rule |
| Reviews | A request flow that reaches every customer, with no gating or incentive | The flow, drawn or described |
| Integration | Connection to your field-service tool, one record per lead | A test lead followed from call to job card |
| Reporting | Monthly page: calls, bookings, quotes sent, follow-ups, reviews asked | A sample report using your data |
| Testing | A 15-call test with an agreed pass mark | The test sheet |
| Training | One session for the office and a one-page guide for the owner | The guide |
| Documentation | A runbook with scripts, workflows, logins and who to call | The runbook |
| Support | Response time and the number of changes included each month | The terms in writing |
| Exit | Handover steps, data export and a notice period | The clause |
A provider that cannot show a sample quote from your own prices or a recorded demo call is selling a brochure. Anything marked "extra" belongs in the price comparison; anything marked "not offered" belongs on your own to-do list.
A bottom-up check: hours times the hourly rate
To test any one-off quote, price the work yourself. The planning hours below are my estimates for a small plumbing firm with its software already chosen, so adjust them. The hourly figures come from the Contra bands above: $30 for entry level, $100 and $150 for experienced specialists.
| Component | Planning hours | At $30 | At $100 | At $150 |
|---|---|---|---|---|
| Calls: script, number, routing, emergency rule | 6 | $180 | $600 | $900 |
| Quotes: price book, templates, approval rule | 8 | $240 | $800 | $1,200 |
| Follow-ups: sequences and stop rules | 4 | $120 | $400 | $600 |
| Reviews: request flow with no gating | 3 | $90 | $300 | $450 |
| Reporting: a monthly one-page summary | 3 | $90 | $300 | $450 |
| Testing and training: 15-call test, office session | 4 | $120 | $400 | $600 |
| Total | 28 | $840 | $2,800 | $4,200 |
Read the result like this. A fair one-off price for the whole set lands between about $840 and $4,200. A quote of $9,000 for the same scope needs a stated reason, such as heavy custom integration or a platform you will own. A quote under $500 has probably left out the testing or the handover. Monthly care works the same way: three to six hours of monitoring and small changes is $90 to $900 a month across those hourly bands, so a $1,000 retainer should also buy new builds, not only maintenance.
Four-van firm, twelve months: do it yourself or pay someone
Take a plumbing company with four vans, one of them driven by the owner, and one office coordinator, which makes five software users. It runs on Jobber's Grow plan, at $229 a month on annual billing after the first year (the page shows $161 in year one, and $299 on monthly billing). It adds the receptionist for after-hours and overflow calls, about 60 conversations a month, which comes to $29 plus 30 extra at $0.79, or $52.70 a month. Jobber's Plus plan would include the receptionist with no limit, but for five users it costs $399 a month on annual billing after the first year against $229 for Grow, so on receptionist cost alone it pays only above about 210 conversations a month. Add two AI assistant seats at $20 each on annual business billing and Zapier Professional at $19.99 a month, and value the owner's time at $50 an hour. The two columns below differ only in who does the build and the monthly care.
| Line | Do it yourself | Done for you |
|---|---|---|
| Field-service software, 5 users ($229 x 12) | $2,748 | $2,748 |
| AI receptionist add-on, 60 conversations a month ($52.70 x 12) | $632 | $632 |
| Two AI assistant seats ($20 x 2 x 12) | $480 | $480 |
| Automation tool ($19.99 x 12) | $240 | $240 |
| One-off build | $1,400 (28 hours of your time) | $2,800 (28 hours at $100) |
| Monthly care | $1,200 (2 hours a month of your time) | $4,800 ($400 a month) |
| Your time briefing and testing | Included above | $300 (6 hours) |
| Year-one total, Jobber at full price | $6,700 | $12,000 |
Jobber's first-year price of $161 a month would take $816 off both columns. The gap is $5,300, which is 106 hours of the owner's time at $50, or about 15 extra jobs a year if each leaves $350 of gross profit. Use your own numbers, but the shape holds: the package has to either free more owner time than it costs or win jobs you would otherwise have lost, and a calls-only start tests the second without paying for the first. If you have never built an automation, double the do-it-yourself hours before deciding. What a small plumbing firm pays each month by van count gives the software side in more detail.
Three quotes side by side, filled in
Suppose three providers send these quotes. Quote A is shaped like the small agency's entry tier. B and C are invented to show a mid-range and a high-end scope.
| Quote A | Quote B | Quote C | |
|---|---|---|---|
| Price | $297 setup, $197 a month | $2,800 setup, $400 a month | $9,500 setup, $1,500 a month |
| Year one | $2,661 | $7,600 | $27,500 |
| Calls | Missed-call text-back only | AI answering with an emergency rule | AI answering with multi-van routing |
| Quotes | Not included | Price book, templates, approval rule | Price book, approvals, margin reports |
| Follow-ups | Seven-day sequence | 21-day sequence with stop rules | Same, plus maintenance-plan renewals |
| Reviews | Automated requests | Requests to everyone, no gating | Same, with monthly reporting |
| Acceptance test | None stated | 15-call test before final payment | 15-call test and 30-day tuning |
| Accounts in your name | Not stated | Yes, provider added as admin | Yes, with a runbook and training |
Compare by component, not by total. A is cheapest because it leaves out the two most expensive jobs, AI call answering and quoting, and it says nothing about testing or ownership. B costs roughly what the bottom-up check predicts at a $100 hourly rate. C suits a firm with many vans and a dispatcher; for a four-van firm its extra cost buys reporting you may not read.
One van, four vans or twelve: where each price tier fits
One van. Buy the calls piece only. Jobber's receptionist add-on is $29 a month for 30 conversations and $0.79 for each one after that, and the owner can write the follow-up and review messages in an afternoon. If you pay someone, pay for the call flow and the emergency rule: six hours at the bottom-up rates is $180 to $900, so a $2,000 quote for a one-van firm needs a very good explanation.
Four vans. This is where a done-for-you build can earn its fee, because five people share one booking flow and the office coordinator is the bottleneck. Expect a one-off quote in the $840 to $4,200 range from the check above, monthly care of $90 to $900, and software of about $4,100 a year on top.
Twelve vans. Jobber's own page sends teams of 16 or more users to its sales team, which is a sign that quotes at this size become bespoke. The scope grows to dispatcher routing, several phone lines, margin reporting and training for a bigger office, which pushes the one-off price into Contra's complex band of $2,000 to $10,000 or more and the retainer towards $1,000 or above. Ask for a four-week pilot on one line and one service area before committing to all of it.
Ownership checks before you sign anything
The package that fails most owners is not the expensive one but the one built in the provider's accounts. The test question is: if we part ways tomorrow, what do I hold by Friday?
| Item | Safe arrangement | Red flag |
|---|---|---|
| Business phone number | Yours, or held at a carrier in your name | Lives only on the provider's account |
| Google Business Profile | You are the owner; the provider is a manager | The provider is the owner |
| Field-service or CRM account | Your subscription, provider invited as admin | Provider's account holds your customers |
| Automation account (Zapier, Make, n8n) | Built in your account | Built in the provider's account |
| Call script and AI instructions | Delivered as a document | Called "proprietary" and withheld |
| Recordings and transcripts | Stored where you can export them | Retention and access unstated |
| Customer list and job history | Exportable as a CSV on request | Viewable only inside their dashboard |
The reason this matters is practical. Zapier says a copied Zap arrives switched off, its connections must be reconnected, its run history stays behind and its webhook URLs change, so moving a build between accounts is a rebuild, not a copy. n8n exports include the names and IDs of credentials but not the secrets themselves. Ask for the build in your own account from day one, with the provider added as a collaborator.
Contract clauses worth reading twice
- Minimum term and renewal. Month-to-month after the build is a fair default; Smith.ai's page describes its plans that way. Watch for twelve-month terms that renew automatically.
- Notice. Thirty days is a reasonable ask. Check that notice can be given by email.
- What the setup fee buys. It should be tied to the acceptance test, with the last part payable only after the test passes.
- Usage charges. On Smith.ai's Pro plan calls beyond the 75 allowed cost $2.50 each, and Jobber's add-on charges $0.79 a conversation after 30, so a busy week matters. Ask for the allowance and the rate beyond it.
- Change requests. How many small changes a month are included, and the rate after that.
- Data. Where recordings are stored, how long, who can listen and what is deleted on exit.
- Referral income. Ask which tools the provider earns commission on. Published affiliate programmes show it exists: Make pays affiliates 35% for 12 months, n8n 30% for 12 months and HighLevel 40% recurring, as listed in September 2026. A commission is not wrong, but it should be disclosed.
- Liability. What the provider accepts if an emergency call is missed. Contracts often cap this liability; read the cap and tell your insurer.
Have a solicitor read the contract if it hands over your phone number or your customer data, and compare the clauses with the wider breakdown of what automation agencies charge and what is extra. If you are weighing a package against handing the build to a person you direct, done-for-you against done-with-you covers the difference.
What the package must refuse to automate
A plumbing package should have a short written list of things the assistant hands to a person, and the first item is danger to people. For a gas smell, a carbon monoxide alarm, water near electrics or sewage coming up into a home, the first instruction is to leave if needed and call the emergency services, and only then does the assistant alert your on-call plumber. Here is a short rule you can adapt:
EMERGENCY RULE
If the caller mentions a gas smell, a carbon monoxide alarm, flooding near
electrics, or sewage backing up: tell them to leave the property if it is unsafe and
to call the emergency services first. Then alert the on-call plumber immediately by
call and text, and book nothing further until a person has spoken to the caller.
Never give repair instructions. Never quote a price for an emergency.The same list should include fixed-price quotes for large jobs without a site visit, any diagnosis of a fault from a description, warranty decisions, refunds, and promises of arrival times that are not tied to live dispatch. If the provider's demo does not show the hand-off to a human, ask to see it before any money moves. AI receptionists for plumbers: cost, burst-pipe rules and booking limits goes into the rules in more depth.
Hidden costs, and how to keep the bill down
The costs that surprise owners are rarely the setup fee. Your own software, which in the four-van example is about $4,100 a year, sits outside any package. Call or conversation allowances run out in a busy week. Texting can carry separate message fees and registration steps, so ask what is included. Moving a phone number can cost time and a porting fee. And someone on your side must read transcripts, which at 20 minutes a working day is about seven hours a month, or $350 at $50 an hour.
To keep the bill down, start with calls only for 90 days, using software you already pay for. Insist that the build lives in your accounts. Pay in two parts, half at the start and half after the acceptance test passes. Stay month-to-month once the build is done. Cap the monthly changes in writing. And once the call flow is stable, bring the easier jobs, such as follow-ups and review requests, in-house; half of the planning hours in the table above are in calls and quotes.
A 15-call acceptance test before the final payment
Write the test into the contract so "it works" means something. Fifteen calls make a manageable set; a 15-call test before an AI voice agent takes real jobs has the full script. The groups below show the spread.
| Calls | Scenario | Pass looks like |
|---|---|---|
| 3 | Emergencies: gas smell, burst pipe, sewage backing up | Emergency instruction first, on-call alerted within your agreed time |
| 4 | Quote requests: water heater, repipe, blocked drain, bathroom refit | Right details collected; no price promised beyond your rule; visit or call booked |
| 2 | Existing customers asking for a callback or an invoice copy | Recognised and passed to the office, not treated as new leads |
| 2 | Price shoppers pressing for a number | Polite refusal to guess; offers a visit or a call |
| 2 | Spam and a wrong number | Ended quickly with no job card created |
| 1 | A job outside your service area | Declined politely, no booking |
| 1 | A booking change | Handled, or passed to a person, without double-booking |
Agree the pass mark in advance, say 14 of 15 handled correctly, and pay the second half only when the provider reaches it. Run the same test again after any change to the call script, because a small edit to one rule can break another.
Questions plumbers ask before buying a package
Is a done-for-you package worth it for a one-van plumber?
Rarely. A one-van firm on Jobber can switch on call answering for $29 a month, covering 30 conversations before $0.79 each, and write its own follow-ups in an afternoon. Pay someone only for the parts you cannot build, such as connecting two systems, and keep it to a fixed fee.
Should the package run on my software or the provider's?
On yours wherever possible. If the provider builds inside its own platform, your customers, number and workflows live in its account, so exit means a rebuild. If it must use its platform, get a written export route and a ported number before paying.
How long should setup take?
A calls-only receptionist can be switched on in an afternoon. A connected build with quotes, follow-ups and reviews is closer to two to four weeks, because the testing and the price book take longer than the configuration. Be wary of a promise to launch everything in a day.
Can I get my money back if it does not work?
Only if you write the test into the contract. Agree measurable acceptance criteria, such as 14 of 15 test calls handled correctly, and pay the final instalment after they pass. Some providers advertise guarantees, so read the exact wording and what it covers.
Does automated review asking break Google's rules?
Not if you ask every customer, offer nothing in return and do not ask for reviews that mention specific things such as a technician's name. Selecting only happy customers is the common breach. Check the provider's flow against those rules before it goes live.
