How to manage construction backlog

Track backlog as remaining contract revenue and remaining gross profit on signed work, convert it into months of work and crew capacity, and review it every month so it drives what you bid, who you hire, and how you plan cash.

To manage construction backlog, keep one list of every signed contract with the revenue and gross profit still left to earn, turn that into months of work for each crew type, and review it on a fixed monthly date. Then use it to make three calls: how hard to chase new work, when to add or hold people, and how much cash the company will need to carry the jobs it already has. Backlog is not a bragging number. It is a forecast, and it is only as good as the margin inside it.

Plenty of contractors know their backlog in round numbers ("about $9 million on the books") and still get surprised by a slow summer or a crew stretched across four jobs at once. The fix is to measure it the same way every month and to look at it from more than one angle.

What counts as construction backlog

Backlog is the unearned part of signed contracts. Take each contract's current value, including approved change orders, and subtract the revenue already earned to date. What is left is backlog. Your WIP report already has most of these numbers, because earned revenue there comes from cost to date against estimated total cost.

  • Include: signed contracts, executed subcontracts, approved change orders, and signed letters of intent if you are confident they convert.
  • Keep separate: verbal awards, low-bid notices without a contract, and pending change orders. Track them as "probable" with your own odds, but never mix them into the main number.
  • Leave out: bids still out, budget pricing, and anything the client has not committed to in writing.

How to manage backlog step by step

1. Build one backlog schedule

One row per job: contract value, approved changes, earned to date, remaining revenue, estimated gross profit percent, remaining gross profit, start date, and forecast finish. Pull the earned figure from the WIP so the two reports never disagree. If backlog lives in the estimator's head and the WIP lives in the accounting file, they will drift within a quarter.

2. Spread remaining revenue by month

A $2.4 million job with eight months left does not burn evenly. Use the schedule to spread remaining revenue across months, front-loading or back-loading as the work actually flows. This monthly spread is what shows the gap that a single total hides, such as plenty of work through June and almost nothing booked for September.

3. Convert dollars into crew capacity

Owners run out of people before they run out of money. Split remaining self-performed labor hours by trade or crew type and compare them with the hours your crews can deliver each month. A company can have a healthy dollar backlog that is mostly subcontracted mechanical work while its own carpentry crews sit light. Your job cost report and estimates give you the remaining hours.

4. Calculate backlog in months

Divide remaining revenue by your average monthly revenue. Then do the same with remaining gross profit against your monthly overhead. The second figure answers the question owners actually care about: how many months of overhead the signed work will cover. If backlog gross profit covers four months of overhead and you need twelve, the new work you win in the next two quarters decides the year.

5. Review it on a fixed monthly date

Hold the review a few days after the WIP closes. The owner, the lead estimator, and operations should be in the room. Walk through the monthly spread, the crew capacity chart, and the probable list. Each review should end with decisions: bid more or less aggressively, pull a start date forward, move a superintendent, or hold off on a hire.

6. Tie backlog to bidding and hiring

When backlog is thin, the temptation is to cut margin to win anything. Fill the gap with work that fits your crews instead, and set a floor margin you will not go below. When backlog is heavy, raise prices, get choosier, and push start dates you cannot staff. The guide on how to decide which construction jobs to bid covers the screening side.

Worked example: a $12 million commercial contractor

Here is an illustration. Say a general contractor with about $12 million in annual revenue and $1.1 million in annual overhead closes September with this signed work:

Example backlog schedule at September 30
JobRemaining revenueGross profit %Remaining gross profitForecast finish
Medical office build-out$2,100,0009%$189,000February
Retail shell, phase 2$1,450,00011%$159,500January
Church addition$1,900,00014%$266,000May
Two small TI jobs$550,00018%$99,000December
Total$6,000,00011.9%$713,500

At $1 million of revenue a month, $6 million looks like six months of work. The gross profit view is less comfortable. Monthly overhead is about $92,000, so $713,500 covers roughly 7.8 months of overhead in total, but the monthly spread shows that most of it is earned by February. From March on, only the church addition is producing revenue, and the carpentry crews are free in April.

The decisions write themselves. The estimator focuses the next 60 days on jobs that can start in March or April and use self-perform carpentry. The owner keeps the margin floor at 10 percent instead of chasing a low-margin warehouse. A superintendent who would have rolled off in February is assigned to manage preconstruction on two likely jobs instead of being laid off.

Healthy backlog: how much is enough?

There is no single right number. It depends on job length, how quickly you can start new work, and how steady your market is. A service-heavy remodeler might be fine with two or three months booked, while a contractor doing 18-month public jobs needs a much longer runway. The better test is whether backlog gross profit covers overhead for the period it takes you to win and start new work, plus a cushion. Track the trend: backlog that shrinks three months in a row is a warning even if the total still looks large.

Too much backlog is a problem too. If signed work needs more superintendents, working capital, or bonding capacity than you have, the company is overcommitted. Late starts, burned-out PMs, and margin fade follow. See how to manage growth without losing profit.

Mistakes to avoid

  • Counting verbal awards. A job is not backlog until the contract is signed. Keep a separate probable list.
  • Using the bid margin forever. Update gross profit on each job as costs come in. Backlog built on stale estimates overstates profit.
  • Ignoring pending change orders. They belong on the probable list, not in contract value, until they are approved.
  • Looking at the total, not the timing. Six months of backlog that all finishes in three months is a cliff, not a cushion.
  • Not splitting self-perform from subcontracted work. Your crews care about hours, not dollars.
  • Reviewing it only when sales are slow. By then the gap is already on the calendar.

Templates and tools that help

Start with a WIP report template so earned revenue is calculated the same way every month, and a construction cash flow template to spread backlog into expected billings and costs. If you are building the habit, construction KPIs every owner should track and how to forecast cash flow for a construction business fit next to this guide.

Smart Business Automator keeps contract values, change orders, job costs, and WIP views in one place, so the backlog schedule updates from the same numbers as billing. See job costing and WIP automation.

Frequently asked questions

What is a good backlog for a construction company?

It depends on job length and how fast you can start new work. A useful test is whether the gross profit left in signed work covers overhead for the time it usually takes to win and start the next jobs, with some cushion.

Should pending change orders count as backlog?

Not in the main number. Track them on a separate probable list until they are approved and added to the contract value.

How often should backlog be reviewed?

Monthly, a few days after the WIP report closes, so earned revenue and backlog come from the same cost data. Busy or volatile periods can justify a quick check every two weeks.

What is the difference between backlog and pipeline?

Backlog is signed work not yet earned. Pipeline is work you are pursuing or have bid but not won. Keep them in separate reports so one never inflates the other.

Why does backlog matter to bonding companies?

Sureties look at how much uncompleted work a contractor already carries when they set bonding limits. Accurate backlog and WIP schedules make that conversation easier.
