Billing

What is progress billing in construction?

Progress billing is the practice of invoicing a construction customer in periodic installments, usually monthly, based on the share of work completed since the last bill, instead of billing the whole contract at the end.

Progress billing is how most commercial construction gets paid. Instead of one invoice at the end of a six-month job, the contractor bills each month for what was completed that month. The document used is usually a pay application, built on a schedule of values that breaks the contract into line items. Each line is billed by percent complete, minus retainage.

The reason is cash. Contractors pay crews weekly and suppliers monthly. Waiting until the end to bill would mean financing the whole job. Progress billing keeps the money roughly in step with the work.

How progress billing works

  1. Agree on the schedule of values and billing date at the start of the job.
  2. Near the end of each period, the PM and superintendent estimate percent complete for each line.
  3. The office prepares the bill, usually on AIA G702 and G703 forms or the owner's format, with lien waivers and backup.
  4. The owner, architect, or lender reviews it, adjusts if needed, and approves.
  5. Payment arrives on the terms set by the contract and any prompt payment law.

A worked example

Say a mechanical sub has a $400,000 contract split into four lines on the schedule of values, with 10 percent retainage. At the end of month three, the PM reports progress as shown.

Example: month three progress billing
LineScheduled value% complete to dateEarned to date
Underground and sleeves$40,000100%$40,000
Ductwork$160,00050%$80,000
Equipment$120,00025%$30,000
Controls and startup$80,0000%$0
Total$400,00037.5%$150,000

Earned to date is $150,000. Less 10 percent retainage, $135,000 is billable to date. If $81,000 was billed in months one and two (net of retainage), this month's bill is $54,000.

Federal progress payments

On federal fixed-price construction, FAR 52.232-5 provides for monthly progress payments (or more often if the contracting officer decides) based on estimates of work accomplished. Each request needs an itemization and a signed certification about subcontractor payments. If progress is not satisfactory, the contracting officer may retain up to 10 percent of the payment. Under FAR 52.232-27, a progress payment is due 14 days after the designated billing office receives a proper payment request.

Common mistakes

  • Overstating progress. It may speed up cash for a month, but it creates overbilling and erodes trust with the reviewer.
  • Underbilling out of caution. Leaving earned work unbilled finances the owner's project. See underbilling.
  • Missing the cutoff. Many owners only process bills received by a set date each month.
  • Billing change orders before they are signed. Most owners will reject the whole application.
  • Forgetting stored materials rules. Some contracts allow billing for stored materials only with proof of insurance and title.

Subcontractors feel progress billing one step removed. The GC usually sets a sub billing date several days before its own pay app is due, so it can roll every sub's numbers into one request. A sub that misses that internal cutoff often waits a full extra month, even if its work was done on time.

Frequently asked questions

Is progress billing the same as a progress payment?

They are two sides of the same process. Progress billing is the contractor's invoice. The progress payment is the owner's payment against it.

How often is progress billing done?

Most contracts call for monthly billing. Federal fixed-price construction contracts provide for monthly progress payments, or more often if the contracting officer decides.

How is percent complete decided for progress billing?

Usually by the PM's estimate for each schedule of values line, reviewed by the owner or architect. Some contracts use measured quantities instead.

Can residential contractors use progress billing?

Yes. Residential jobs often use milestone draws, such as foundation, framing, and drywall, which are a form of progress billing tied to stages instead of monthly percentages.
