How Percentage of Completion Entries Fix
Revenue Fluctuations for ‘In-Process’ Contracts

The Problem with ‘In-Process Contracts’

Custom builders, remodelers, manufacturers, and other project-based service companies enter into contracts with clients where the jobs extend over relatively long periods of time – from several months to a year or more. For these types of jobs, companies typically invoice in accordance with contract provisions or stages of completion rather than at the end of each month.  As a result, income is nearly always booked either:

  • Before costs are entered to your accounting system, and/or
  • After costs are entered

Then job costs are incurred and entered into the accounting system on an ongoing, but fluctuating, basis. As a result, you’ll see a mismatch between what has been invoiced and what has been earned.  So why is this a problem?  One month you may have lots of income on a job but not much in the way of cost, the next month, you may have little or no income but lots of costs.  The result? A monthly ‘see-saw’ effect on your gross profit results!  (See below for 2 examples):

If you look at the results above, you’ll notice that no single month reflects the true Total job profitability (30% for Job A and 25.5% for Job B).  Each month, standing alone, shows wildly varying and unrealistic profit or loss.  If you’re someone who really has a need to know how a job – or the company – is doing, this could create quite the emotional roller coaster!

With all of the bills and checks and payroll and invoices and cash coming and going, it becomes extremely difficult to know how much you are truly EARNING on a day-to-day, week-to-week, and month-to-month basis on any specific long-term job.  Of course, if you have a good job costing accounting system you will eventually know your final results on any given job, but that’s far too late to take corrective action.

AND if you keep a multitude of projects running at the same time, it can become nearly impossible to nail down your company-wide financial scores for any given time frame!

Percentage of Completion adjustments to the rescue!

The ‘Percentage of Completion adjustments’ technique provides you with a stable, reliable way of matching each job’s life-to-date revenue against its life-to-date expenses so that you can know how this month’s or quarter’s profit “lines up” against last month’s, last quarter’s or last year’s.  And if your job profitability reflects reality, your company-wide numbers will more clearly reflect reality.

How is it done?  Your income is adjusted up or down each month so that the income earned has a corresponding relationship to costs incurred.  For example, if you anticipate a 30% gross profit on a job, and life-to-date you have incurred 60% of the costs on a job, your income is adjusted to reflect 60% of your anticipated income. The result:  you’ll see your anticipated gross profit reflected each month that the job is open.  Simply stated, the entries provide a way to “level” your financial results across accounting periods.  Please see the example below that illustrates how the income looks for Jobs A and Job B AFTER Percentage of Completion adjustments.  Quite a difference in what you see each month, isn’t there?  (Be sure to compare the ‘before and after’ pictures…)

As you’ll see from the results above, Percentage of Completion entries act much like the bubble in a common level (i.e., They temporarily adjust revenue for individual jobs to proportionally match costs incurred.  The adjusting entries are made at the end of a month, and are then reversed.)

This provides a much clearer picture of production activity and related earnings and is why percentage of completion calculations & adjustments are required by:

  • Various national consulting groups (so participants can compare true productivity and profitability with other participants).
  • Many bonding companies
  • Banks who track company profitability on their borrowers
  • The IRS for businesses above a certain gross revenue level (see your tax advisor or this IRS article for specifics).  NOTE:  Regardless of tax reporting requirements, the percentage of completion method of accounting provides the best management information on longer-term jobs as it matches costs incurred with income earned.  The POC method can be utilized for internal reporting purposes even if your tax advisor uses a different tax reporting method.

Extra Percentage of Completion Benefits – Especially for Owners & Managers

In addition to seeing ‘smoothed out’ gross profits on jobs and more realistic bottom line management reports, you should also reap the following bonuses:

  • As you undertake the discipline of helping to assemble your numbers for the Percentage of Completion calculations, you will become much closer to your critical numbers:  estimated income and costs, change orders, allowances, and over/under-runs.
  • You will gain a much deeper understanding of exactly how individual jobs are shaping up from a financial standpoint as they progress.  And from there, you will be able to quickly take corrective action to complete each job that much closer to “on time” and “under budget.”
  • When owners and managers have access to accurate measurements, they automatically begin to take steps to improve their results!
  • When you know what your numbers REALLY are, you can save the ‘roller-coaster’ thrills for the amusement park.  When you’re running a company, a nice, smooth train ride is preferable…

In Summary

Yes, it will require a small investment to get your Percentage of Completion adjustments ‘up and rolling’, but the payoffs are significant.  If you’ve experienced those fluctuating numbers, having to continually guess what’s still coming in the door for ongoing jobs, the ongoing disquiet of not knowing where you stand on a job until AFTER it’s completed, or the sense that finances are out of control because you don’t know where your company REALLY stands, it’s time to move these adjustment techniques and reporting improvements to the top of your list!
