Fence contractor margin audit: finding leaks job by job across a season
An audit of finished fence jobs that shows where margin went, break-even in crew days, and four common leaks: return visits, travel, gates, and unbilled variations.
What to take away
- This is an audit, not a benchmark. Take last season's finished jobs and find out where the margin actually went, job by job.
- Break-even for a fencing business is best expressed in crew days rather than in revenue, because crew days are what the season limits.
- Margin usually leaks in four placesthe return visit after cure, travel, gates, and work done outside the written scope without a signed variation.
- Any published margin figure describes a different business. The numbers in this exercise are all yours.
Why an audit beats a benchmark
A benchmark tells you what somebody else reported. An audit tells you what your own jobs did, and it points at a specific thing to change on Monday.
You need three things from the past season: the price actually received per job, the direct costs recorded against that job, and the crew days each job consumed. If any of those are missing, that gap is itself the first finding.
Break-even in crew days
Revenue based break-even is hard to act on. Crew day break-even is not.
Crew day break-even in five steps
- Total fixed costs from your accounts
- Average contribution per crew day
- Divide fixed costs by contribution
- Compare to sellable crew days
- If not larger, problem is structural
- Total your fixed costs for the year from your own accounts, including the owner's non-installing time.
- Compute the average contribution per crew day across last season: price received minus direct costs, divided by crew days consumed, averaged over completed jobs.
- Divide fixed costs by contribution per crew day. That is how many crew days must be sold before the business covers itself.
- Compare that to the crew days you can actually sell, after weather, travel, the slow season and the days lost to weather that stops digging.
- If the second number is not comfortably larger than the first, the problem is structural rather than a matter of selling harder.
Step four is the one that turns this from arithmetic into information. A fencing year is not twelve even months, and a break-even that assumes it is will always look reachable.
The audit: where the margin went
Work through the finished jobs and sort them by contribution per crew day. Then look at the bottom group and test each of the following.
Margin leak audit checklist
- Return visit counted as crew day?
- Travel hours added both directions?
- Gate hours estimated separately?
- Unsigned variations invoiced?
- Ground surprises clustered geographically?
- Rework and callbacks counted and caused?
The return visit. Was the trip back after cure counted as a crew day? Operations that treat it as a half hour of finishing routinely understate the cost of every installation.
Travel. Add up the hours between leaving the yard and starting work, both directions, for every visit. Compare that against the job price. Jobs at the edge of your radius often show a healthy margin per hour on site and a poor one per day.
Gates. Check whether gate hours were estimated separately or absorbed into panel work. A gate priced as if it were fence is the most common single leak in this trade, and it also generates the callbacks.
Unsigned variations. Find every job where the crew did something not in the scope: a post moved, an extra section, a stump removed, spoil taken away. Then check whether it was invoiced. Work done and not billed is a decision somebody made on site without knowing the cost.
Ground surprises. Separate the jobs where the ground was harder than assumed. If those jobs cluster geographically, that is a quoting rule waiting to be written, not bad luck.
Rework and callbacks. Count the return trips that were not planned. Then look at what caused them: gate alignment, post movement, fabric tension, or a gap at grade the customer did not accept.
Turning findings into changes
An audit is only useful if each finding names something that changes.
Findings and the changes they imply
Finding
- Return visits uncosted
- Add return day to estimates
- Edge of radius losing
- Travel rule or surcharge
- Gates absorbed
- Separate line with hours
- Variations not billed
- Written on-site variation form
- Ground harder in one area
- Soil note on checklist
- Callbacks on one detail
- Quality check before leaving
Change
- Return visits uncosted
- Edge of radius losing
- Gates absorbed
- Variations not billed
- Ground harder in one area
- Callbacks on one detail
| Finding | The change it implies |
|---|---|
| Return visits uncosted | Add the return day to every installation estimate |
| Edge of radius jobs losing money | Set a travel rule or a distance surcharge at quote stage |
| Gates absorbed into panel pricing | Make gates a separate line with their own hours |
| Variations done and not billed | A written on-site variation form the crew can actually use |
| Ground harder than assumed in one area | A soil note on the quoting checklist for that area |
| Callbacks concentrated on one detail | A quality check for that detail before leaving site |
Notice that none of these are price increases. Most margin recovered in a fencing business comes from estimating and scope discipline rather than from charging more, which is why the audit is worth running before the price review.
The records this depends on
You cannot audit what you did not record. At minimum, track job level material costs, crew hours split by operation, and a note of every variation.
The Internal Revenue Service: What kind of records should I keep? guidance describes a system that clearly shows income and expenses, backed by the documents behind purchases, sales and payroll.
For the labor cost assumption inside contribution, the U.S. Bureau of Labor Statistics: Occupational Employment and Wage Statistics Tables publish employment and wage estimates by occupation, industry, state and metropolitan area, useful as a check on the pay side of your burdened rate.
If the audit leads you to advertise differently, the Federal Trade Commission: Advertising FAQs: A Guide for Small Business guidance is the standard any new claim has to meet.
What to do with the result
Feed the findings into the estimating rule rather than into the price list first. The mechanics of that rule are in the fence contractor pricing and profit guide, and the margin arithmetic itself is in how to price fence contractor services for a fair margin.
Where the audit points at capacity, not pricing, the answer is usually equipment or crew.
The fence contractor equipment and setup guide covers what changes a day's output. The equipment checklist for new owners covers the small items that quietly cost hours. Update the assumptions in the fence contractor business plan once the season's numbers are in, because that document is where next year's decisions get made.
Common questions
How many jobs do I need for this to be meaningful?
Enough that each service family has several, and enough that at least one difficult site is included. An audit of only your good jobs will tell you everything is fine.
Should I use average or median contribution?
Median, for the family comparison. One unusually good job can carry a family that normally loses money, and the median will show you that where an average will not.
What if the audit says a whole service line loses money?
Look at why before dropping it. Repair work, for instance, often loses money because it is interleaved with installation rather than because it is unprofitable. The fix may be scheduling rather than abandonment.
How often should this be done?
Once a season is enough for the full audit. The gate and variation checks are worth running monthly, because those two leak continuously and are cheap to catch.
