Gutter Installation Invoice Example: Every Line Explained

Short answer: A gutter installation invoice example has to bill two units, because feet along the eave and drops down the wall do not move together. The job below runs 202 linear feet and 115 vertical feet across five downspouts. The five drops are $1,275 of a $7,054.50 invoice — 18 percent on five items — and 34 feet of copper porch gutter is 17 percent of the length and 28 percent of the money.

One house: a two-and-a-half story foursquare with a rebuilt front porch, replaced in a single day by a crew of three. The customer had one competing bid written as a single per-foot number, which is why this invoice separates the run, the drops, the material, and the guard. What follows is every line, the ones that generate a phone call, and how the proposal ties to the final bill. The unit logic behind the rates is in gutter pricing guide.

Why do 202 feet of gutter carry 115 vertical feet of downspout?

Because the run collects water and the drops move it, and only one of those is measured along the eave.

Five drops on this house: two at 31 feet from the third-story eave to grade, two at 21 feet, and the porch at 11 feet. Add them and the crew installed 115 feet of downspout, more than half the length of the gutter itself, plus elbows, straps, and an outlet cut and sealed in each run. None of that is visible in a per-foot price and all of it is material and time.

Lines 7, 8 and 9 total $1,275 — 18 percent of the invoice on five items. Put the drop count and the vertical feet in the header where the customer can compare them against another bid, because the cheaper bid is very often the one with three drops instead of five.

What does the height of a drop actually change?

Everything about how the day runs, which is why line 7 and line 8 are the same downspout at different prices.

A 31 ft run is 48 percent more material than a 21 ft run and needs an extra strap, but the money is in the access. Working above the second-story roof line means longer ladders set properly, and OSHA’s portable ladder rules require the side rails to extend at least 3 feet above the landing, or the ladder tied off at the top, with the base set out one foot for every four feet of working length. On a foursquare that means the ladder foot lands in a planting bed, staging takes two people, and every trip up carries one section instead of three.

That is $268 against $172 for identical stock in identical color. Write the height on the line — “31 ft run, straps at 8 ft” — and the difference stops looking arbitrary.

Why is the porch 17 percent of the length and 28 percent of the money?

Material, and the labor that material forces on you.

Thirty-four feet of half-round copper and one copper drop come to $1,959 of a $7,054.50 invoice. Copper coil runs several times aluminum per foot on the supplier ticket, so price that line off your own invoice rather than a multiplier. Then add what copper does to the crew: joints and end caps are soldered instead of riveted and sealed, half-round hangs on its own hanger system, and a torch on a rebuilt porch means a fire watch and a very careful hand around new trim.

The aluminum on this house billed $11.40 per foot. The copper billed $46.00. Averaged across the invoice the job is $34.92 per foot, a number that describes neither material and should never appear on a bid.

Which lines get pushed back on, and how should they read?

The line they call about	What they are thinking	Write it like this
Mobilization, $385	”You are charging me to show up."	"A machine trailer on two permitted street spaces, coil racked to run seamless on site, and 40 ft ladders staged on three elevations before the first foot is formed.”
Third-story drops, $536 for two	”It is the same downspout as the front."	"31 ft against 21 ft, an extra strap each, and ladder work above the second-story roof line with the base set four to one into a planting bed.”
Copper, $46 a foot	”It is the same gutter shape."	"16 oz copper stock against .032 aluminum on the supplier ticket, soldered joints and caps instead of rivets and sealant, copper hangers, and a fire watch on a new porch.”
Guard, $787.20	”That is a tenth of the bill for screens."	"96 feet of micro-mesh screwed to the hanger under the maple, which is the elevation that clogged. The other 106 feet were left open because nothing overhangs them.”
Fascia, $363	”Your crew damaged it."	"Photo 6, taken with the old gutter down and before the new one went up. Rot at the rear eave under the failed half-round. Priced at the $16.50 per foot conditional rate in the proposal, billed on 22 feet.”
Tear-off, $313.10	”Old metal is worth money."	"Galvanized half-round with spikes driven into the fascia, pulled by hand, and 0.6 ton over the scale. The scrap value does not cover the trip.”
Miters and caps, $356	”Corners should be part of the footage."	"Eight corners formed or soldered by hand and six caps fitted. Seamless means no seams in the run, not no seams at the corners — corners are where gutters leak.”

The pattern is the same every time: replace the adjective with a count and a photo number. “Extra work at the back” is arguable. “22 lf of rot, photo 6, approved 10:40 a.m.” is not.

How do I explain the estimate against this invoice?

The proposal priced a house measured from the ground. The invoice records what came off the trailer, and both documents read in the same order with the same wording so they can be laid side by side.

Two things moved here. The run measured 202 feet on completion against 208 on the proposal, so lines 2 and 3 came down and the invoice prints both figures — ground measurements taken from a driveway are close, not exact, and a customer who sees the smaller number without an explanation still calls. And fascia rot was invisible until the old gutter was down, which is why the proposal already carried it as a conditional line at $16.50 per foot with no dollar figure in the quoted total. CO-1 filled in the quantity at a rate the customer had already accepted.

Nothing on this invoice carries a rate invented after the ladders went up. That is the entire trick, and it is also the answer to the most common estimate dispute in this trade: quantities may move, prices may not.

Why is a cleaning quoted on a completely different unit?

Because cleaning has almost nothing to do with the length of the gutter.

A per-foot cleaning price overcharges an open ranch and loses money on a tight two-and-a-half story with beds under every ladder set. Price cleaning by stories and access with a stated minimum, and name what moves it: guard removal and reinstallation, roof pitch, whether downspouts are flushed, and how much debris comes out. On this house a cleaning is three ladder positions on the third story and a crew of two, which is a different product from the same service on a bungalow. Repairs work the same way — per seam, per drop unclogged, or per section re-hung, each against a trip minimum.

How do I set these rates from my own costs?

Work up from the coil, then check the total against the market rather than the other way around.

Material per foot is the roll price divided by the feet it yields, plus a hanger every 24 inches, screws, rivets, sealant, and the outlet. Miters and end caps come off the same coil, so count them as feet consumed. Do that once per material, because .032 aluminum and 16 oz copper produce completely different sheets. Labor is crew-hours at a loaded rate — wage plus burden, the truck, the machine payment, and the hours nobody bills. Overhead is last year’s fixed cost divided by the feet you actually hung.

Then apply profit as a margin, not a markup. A job costing $4,900 with 30 percent markup invoices at $6,370, which is a 23.1 percent margin. At a true 30 percent margin the arithmetic is $4,900 ÷ 0.70 = $7,000. That is $630 on one house, and the mistake repeats on every house until the formula changes. Price equals cost divided by one minus the margin.

What goes in the file when the ladders come down?

Photographs first: the old system before tear-off, the fascia with the gutter down, the rot with a tape on it, each drop from the ground showing its run, and the finished elevations. Then the signed proposal, CO-1 with its timestamp, the coil and copper supplier tickets, the dump ticket, and the street parking permit. Supplier tickets are receipts rather than invoices, and the distinction is worth knowing at tax time — what to include on an invoice draws the line.

Keel keeps that on the phone in your pouch, entirely on the device — no account, no bank connection, no cloud, no login, and an App Store privacy label reading Data Not Collected. Photograph the copper ticket at the counter and the dump ticket at the gate; Apple Intelligence reads them there, which is how the most expensive material on this job stays attached to the job that consumed it, and the rest of that ledger is in gutter business expenses. Supply runs and the trip back for two more elbows log as mileage. The invoice goes out from the trailer in about a minute with your own numbering, your logo, your brand color and a payment link the customer scans as a QR code, which is most of how to get paid for gutter work. The $2,100 deposit was copper and coil rather than profit, and Freeboard says exactly that: cash minus tax reserve, minus committed invoices, minus a buffer. Free covers unlimited invoices, receipts and mileage; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription.

Frequently asked questions

What should a gutter installation invoice include?

Linear feet by material and profile, the hanger type and spacing, downspout count with the run height of each drop, miters and end caps by count, guard footage and where it was installed, tear-off and disposal on their own line, any fascia repair with a photo reference and an approval time, plus the deposit received and the balance due.

Why are downspouts billed separately from linear feet?

Because they are a second unit going the other direction. This house had 202 feet of gutter and 115 vertical feet of downspout across five drops, each with an outlet, elbows and straps. A per-foot price that includes drops silently overcharges a low ranch with two drops and loses money on a tall house with five, which is where most gutter bids go wrong.

Why do third-story downspouts cost more than second-story ones?

Material and access. A 31 ft run is 48 percent more stock than a 21 ft run and takes an extra strap, but the real cost is working above the second-story roof line: longer ladders with the rails extended past the landing or tied off, the base set one foot out for every four up, and two people staging every position. On this invoice that is $268 against $172.

How much more does copper gutter cost than aluminum?

Price it from your own supplier ticket rather than a rule of thumb, because copper moves with the commodity market. On this job 16 oz half-round copper billed $46.00 per foot against $11.40 for .032 aluminum, and the gap is not only material — copper is soldered rather than riveted, hangs on its own hangers, and needs a fire watch when there is a torch near new trim.

How do I bill fascia rot found after the old gutter comes off?

As a conditional line written into the proposal with a per-foot rate and no quantity, filled in on the invoice once the wood is visible. Photograph it before the new gutter goes up, note the time the customer approved it, and bill only the feet you replaced. A rate agreed in advance is a bill; a number attached while you are standing on a ladder is a negotiation.

What is the difference between a gutter estimate and the final invoice?

The estimate prices a house measured from the ground; the invoice records what was installed and measured on completion. Print the quoted and measured footage together whenever they differ, keep the same line order and wording in both documents, and make sure every rate on the invoice already appeared on something the customer signed, including the conditional lines.
