Tree Service Estimate Template: Itemise Jobs With AI

A tree service estimate should list each tree and the work on it as separate priced lines: removal method and crew time, crane or lift hire, chipping, stump grinding, haul-away and clean-up, followed by exclusions, conditions and a validity date. AI can turn your site notes into those lines and wording, but you supply the measurements and the prices.

The usual failure is a single price for the whole job. "Remove oak and grind stump, $2,400" leaves the customer assuming the logs, the chips and the stump hole are all included, and leaves you arguing about it on the day. Itemised lines also let a customer drop an optional line, such as the stump, without asking you to re-quote.

Treat the AI as a note-taker with a good memory for what usually gets forgotten, not as an arborist. It can't judge a tree's condition, measure its height or see the gate from a photo, and it is unreliable at adding up a long column. Your site notes, your rate card and a spreadsheet formula carry the facts. The AI organises, words and checks.

One lump sum, three different assumptions

Take a lump-sum estimate that reads "Remove three trees at rear, grind stumps, clear up: $5,900." The customer reads "clear up" as logs gone, chips gone and the lawn raked. The crew reads it as brush chipped and logs left in a pile by the fence. Neither is wrong, because the sentence allows both, and the disagreement surfaces at the end of the job when everybody is tired.

The same job itemised says something else entirely: chips left in a heap at the back, logs from two trees hauled away in two loads, stump grinding optional at $1,091, crane booked for a four-hour minimum. Every assumption is now a line the customer can read, question or remove. If they decide to keep the logs, one line comes out. If the stump grinding is the sticking point, they can drop it without a second visit from you. The full version is in the worked estimate below.

The lines a tree estimate needs, in the order the job runs

This table is the template. Rename the lines to suit your business, but keep the discipline: each line says what is included and how it was priced, in a form the customer can check.

If the customer is a homeowners' association or a property manager, the format changes: they want a tree inventory, unit prices and insurance details, which the commercial and storm cleanup proposal template covers. This tutorial stays with the private-customer estimate.

What to write down on site before any AI sees it

The AI has never seen the tree, so your notes are the job. Capture these on the visit, in any order, and say "unknown" rather than leaving a gap, because a gap becomes a guess when somebody drafts from it later:

• For each tree: species, trunk diameter at chest height, approximate height and spread, lean, visible deadwood or decay.
• What stands under and beside it: buildings, fences, greenhouses, play equipment, service lines overhead or underground.
• Access: gate or passage width, ground conditions, slopes, where a truck, chipper and crane could stand.
• The method you would use, and why (climbing, felling, crane-assisted), plus anything that could change it.
• Stumps: diameter of each, and whether the customer wants them ground.
• What the customer wants done with logs, brush and chips.
• Anything that needs a permit or consent, or that you must ask the customer about.

Dictating these into your phone as you walk round is quicker than typing and keeps your hands free. When you paste the notes into an assistant, use a job reference in place of the customer's name and address. Consumer ChatGPT and Claude accounts let you switch off the use of your chats for model training in their privacy settings, and the business plans of both don't train on business content by default, but the cleanest habit is to leave personal details out in the first place.

A rate card the AI reads and never changes

The AI should never supply a price. It needs a rate card to work from, held in one place and pasted in or stored as project material, so every estimate starts from the same numbers. ChatGPT and Claude both offer Projects, including on free plans with smaller limits, which suits a one-page rate card and your standard exclusions. The figures below are illustrative, not market prices: yours will differ.

Lay the card out one fact per line, with each minimum written as its own rule, because a card that buries "four-hour minimum" inside a sentence is easy for a draft to skip. Add one instruction to every prompt: if a rate you need is not on the card, ask for it and never guess.

Worked estimate: an oak, a dead ash and a boundary row

The job, as an illustration: a back garden with a rear gate onto a service lane wide enough for a small mobile crane, and a side passage only 90 cm wide. An oak stands six metres from a garage and greenhouse, a dead ash has open lawn beneath it, and five conifers run along the boundary. The customer wants all three removed, the oak and ash logs taken away, brush chipped with the chips left at the back, and stump grinding priced as an extra. This is the prompt, with the rate card pasted in above the notes.

You are helping a tree surgery firm turn site notes into an itemised estimate.
Use ONLY the rate card below, and apply every minimum. If you need a rate that is not on the card, ask me; never guess.
Do not add up a total. List each line with its quantity and basis; I will total it in my spreadsheet.
First list any questions you need answered before pricing. Then list the lines grouped as: access, each tree, crane, chipping, haul-away, stumps (as optional), permits.

RATE CARD
(paste the table above, one rate per line)

SITE NOTES (dictated)
Job ref T-0417. Back garden, rear gate onto service lane (small crane can stand there), side passage 90 cm wide.
Tree 1: oak, about 22 m, trunk 85 cm, 6 m from garage and greenhouse, crane needed for the heavy upper sections.
Tree 2: dead ash, about 14 m, trunk 40 cm, open lawn beneath.
Tree 3: row of five conifers on the boundary, about 6 m, trunks around 25 cm.
Customer wants all removed, stumps ground if the price is right, logs from oak and ash taken away, brush chipped and chips left in a heap at the back.

A first draft might come back like the one below. It is an illustration of the shape of a typical answer, including the slips that need catching.

QUESTIONS BEFORE PRICING
1. How long will the crane be on site?
2. Does the oak need a permit or consent check?
3. One or two loads of logs?

DRAFT LINES
Access: ground mats and crane pads, 1 flat, $150
Tree 1 oak: sectional dismantle, crane-assisted, 1 crew day, $1,200
Crane: 3 hours at $240 = $720, plus $300 set-up
Tree 2 ash: climb and dismantle, half a crew day
Tree 3 conifers: fell and cut up, half a crew day
Chipping: brush from all trees, about 6 hours at $90
Haul-away: logs from oak and ash, 2 loads at $190
Stump removal (optional): oak 85 cm = $276; ash 40 cm = $130; five conifers at 25 cm = $81 each; mobilisation $85
Permit check: $95

Five things to fix in the AI's draft

1. The crane minimum. The draft billed three hours ($720 plus $300 set-up). The card says a four-hour minimum, so the real line is $240 an hour times four, plus $300, which is $1,260. The draft was $240 short. A rate card with the minimum on its own line, and "apply every minimum" in the prompt, makes this slip less likely, but your check should still look for it.
2. The stump minimum. Five conifer stumps at 25 cm come to $81.25 each by diameter alone, so the draft showed $81. The card's $120 minimum applies, so the five stumps cost $600, not about $406. That is a gap of roughly $194 on one line.
3. The wording. Customers say "stump removal", but grinding leaves roots and chips behind. Write "grinding to [depth] below ground level; roots beyond the stump not removed; chips left in the hole", with your own depth in place of the bracket.
4. The split crew day. "Half a crew day" for each of two trees invites the customer to ask why one tree costs $600 on its own. Combine them into a single line for the second day, which is how the work will actually run.
5. The assumption nobody questioned. The notes say the ash is dead, and the draft simply priced a climb. Only the climber can decide on the day whether a dead tree is safe to climb. If the answer is no, the method and the price change, so say so in the conditions.

Then do the arithmetic outside the AI. Put quantity, rate and amount in three columns of a spreadsheet, with the amount as =quantity*rate and the total as =SUM() over the amount column. If you want the assistant's help, ask it to write those formulas, not to do the sum. Even then, check the first row by hand.

The finished estimate the customer sees

After the fixes, the lines below go into the customer's copy. Stump grinding sits at the bottom as an optional extra, so the customer sees both totals.

Lines 1 to 7 add up to $4,825, and with the $1,091 of stump grinding the total is $5,916. The customer who keeps the logs and skips the stumps can see their own number straight away: $4,825 minus the $380 haul-away is $4,445.

Exclusions and conditions in plain words

Ask the AI to draft these from your standard list, then cut what doesn't apply to the job and add what does. Wording like this is a starting point: contract terms differ by place and by what your insurer expects, so have the final version read by a qualified adviser. Typical exclusions:

• Underground services that were not marked or disclosed, such as irrigation lines, cables, drains and septic tanks.
• Roots beyond the stump: grinding removes the stump to the stated depth and no further.
• Refilling, topsoil, turf or reseeding after stump grinding.
• Replacement planting.
• Trees and hedges not listed in the estimate, even when they stand next to listed ones.
• Work inside the safe-clearance zone of overhead power lines. If a listed tree is within that zone, the utility or a qualified line-clearance contractor has to make the line safe first, and the work date depends on them.
• Repair of damage that was already there to fences, paving, drains or lawns (we photograph the site before starting).
• Waiting time when access is blocked by parked cars or a locked gate.

And the conditions that belong beside them:

• Method: the price assumes the trees can be climbed or reached safely. If the climber judges otherwise on the day, we agree a revised method and price before work continues.
• Crane booking: a deposit books the crane; if you cancel after the booking, the hire company's cancellation charge passes on at cost.
• Weather: high wind, lightning or ice can delay work, and we rebook at no extra charge.
• Extra work: anything beyond the lines above is agreed in writing, by message or email, before it starts.
• Permits: you confirm that you own the trees and tell us if anything protects them, unless line 7 applies.
• Validity: prices hold until [date].

Small jobs and storm call-outs need a lighter version

Not every job deserves a nine-line estimate. One conifer leaning over a fence, climbable, with the logs taken away, fits on four lines using the hourly rate: crew three hours at $190 is $570, chipper one hour at $90, haul-away one load at $190, which totals $850. If the customer wants the 35 cm stump ground, it is $113.75 by diameter, so the $120 minimum applies, plus $85 mobilisation: $205 more, or $1,055 in all. The structure is identical to the big job, only shorter.

A storm call-out is different, because you can't itemise by tree before you have seen the damage. Quote the hourly rates, the minimum call-out, and a cap: "We will work up to $1,500 and phone you before going over." The script for taking those calls is in AI receptionists for tree services and a storm-call script. The lesson from the full estimate still holds: state the basis, the minimum and the cap in writing before anybody climbs.

A follow-up text that gets a reply without nagging

Most estimates are lost to silence, not to price. A short follow-up, sent to people who asked for the estimate and stopped after the last message, keeps yours near the top of their phone. Ask the AI for three messages with placeholders, then edit them into your own voice. Check the rules on messaging customers where you operate before you automate any of this.

Write three short text messages to a customer who has received a tree estimate. Plain, friendly, no pressure, under 40 words each. Use [first name], [your name], [company], [date], [number] placeholders. Message 1: same day, confirms it was sent. Message 2: day three, offers to adjust the options. Message 3: day ten, says the estimate expires on [date] and invites a reply either way.

• Same day: "Hi [first name], it's [your name] from [company]. I've emailed your tree estimate: three trees, with stump grinding as an optional extra. Reply here or ring [number] with any questions. It's valid until [date]."
• Day three: "Hi [first name], just checking the estimate reached you. If the stumps are the sticking point, I can price the tree work on its own."
• Day ten: "Hi [first name], last note from me: the estimate runs out on [date]. If the timing has changed, tell me and I'll re-date it. Either way, thanks for asking us."

The middle message earns its keep because it offers a concrete way to bring the total down, and the itemised estimate makes that offer easy: drop an optional line and the new number is already on the page. For the wider question of answering enquiries fast, see paid leads against answering every enquiry quickly.

The five-minute check before an estimate goes out

• Every tree has its own line or group, with a location a stranger could find ("rear lawn, left of the shed").
• Each rate and minimum matches the card: crane hours, stump minimum, mobilisation charged once.
• The total on the customer's copy matches the spreadsheet, and the optional lines are totalled separately.
• Logs, brush, chips and the stump hole each have a stated destination.
• Exclusions and conditions are attached, and the validity date is on the page.
• Someone has read the customer's copy aloud once, as the customer, and nothing sounded like a loophole.
• No names or addresses went into the prompt; the job reference did.

Once the template exists, the same structure carries over to other trades. The landscaping estimate template shows the labour, plants and waste version, and for the stump line on its own, pricing stump jobs from photos explains what a photo can and can't tell you. When a customer signs, the access, damage and debris clauses in the tree service contract tutorial pick up where your exclusions stop.

Tree estimate questions owners ask

Should a tree estimate be a lump sum or itemised lines?

Itemised lines suit anything beyond one small, obvious tree. The customer can see what each price covers, drop an optional line such as the stump, and you can still show one headline total. A lump sum is fine for a tiny job if the wording says what happens to logs, chips and the stump.

Can AI price a tree job from a photo?

It can describe what is visible, but it cannot reliably measure height, judge decay or see access, and it knows nothing about your rates. Use photos as a memory aid and for the job file. Price from your own site measurements and your rate card.

What if the customer wants to drop the crane to save money?

Re-price the job as a different method instead of deleting the crane line. Without a crane the crew usually needs more rigging time, and the climber must decide whether a sectional dismantle is still safe. Ask for the new method first, then price crew time again from your rate card.

How long should an estimate stay valid?

Pick a period you can honour; 30 days is one workable choice, and shorter suits jobs where crane costs or the tree's condition could change quickly. Put the date on the estimate itself, not only in the terms, and say what you will do after it passes.
