Billing

What is a pay application in construction?

A pay application (pay app) is the formal document a contractor submits, usually monthly, to request payment for work completed, listing the contract value, work done to date, retainage, previous payments, and the amount due now.

A pay application is the invoice of commercial construction, with a lot more structure. Instead of a single line saying "amount due," it shows the whole contract: original sum, approved change orders, each line of the schedule of values with its percent complete, retainage, and what has already been paid. Owners, architects, and lenders use that structure to check the request against what they see in the field.

The most widely used format is the AIA pair: G702, the summary page with the certification, and G703, the continuation sheet with each line item. Many owners and lenders use their own forms that follow the same logic.

What goes into a pay app

  • Contract summary: original contract sum, net change orders, and revised contract sum.
  • Line-item progress: for each schedule of values line, work completed in prior periods, this period, and materials stored.
  • Retainage: amount held on completed work and stored materials.
  • Previous payments: total of prior certified amounts.
  • Current payment due: completed and stored to date, less retainage, less previous payments.
  • Certification: signed, and often notarized, statement by the contractor.
  • Attachments: lien waivers, certified payroll on public jobs, stored material invoices, and any other backup the contract requires.

On federal fixed-price construction, FAR 52.232-5 requires each payment request to include an itemization of amounts for each element of the work, the amount for work by each subcontractor, the total value of each subcontract, amounts previously paid to each sub, and a signed certification. Payment will not be made without the certification.

A worked example

Say a GC has a $1,500,000 contract with $45,000 of approved change orders and 5 percent retainage. Through month four, work completed is $612,000 and $18,000 of stored materials are on site.

Example: month four pay application summary
LineAmount
Revised contract sum$1,545,000
Completed and stored to date$630,000
Retainage (5%)$31,500
Earned less retainage$598,500
Less previous certificates$441,750
Current payment due$156,750

Why pay apps get rejected or cut

  1. Percent complete the architect or lender does not agree with after a site walk.
  2. Unapproved change orders billed as if they were signed.
  3. Missing lien waivers from the GC or its subs for the prior payment.
  4. Math errors between the G702 and G703, or a schedule of values that does not match the last approved version.
  5. Stored materials with no invoice, insurance, or proof the material is on site or in a bonded warehouse.
  6. Missing the owner's submission cutoff date.

Track each pay app after it goes out, too. Log the date submitted, the date approved, any amount cut, and the date paid. Over a few months that log shows which owners pay on time, which reviewers always trim a line, and how many days of cash each job is really tying up.

Frequently asked questions

How often are pay applications submitted?

Usually monthly, on a date set in the contract. Some residential and smaller commercial jobs bill at milestones instead.

Is a pay application the same as an invoice?

It is a type of invoice, but more detailed. It shows the whole contract status and progress by line item, not just the amount due.

Do subcontractors submit pay applications?

Yes. Subs submit pay apps to the GC, which rolls them into its own pay app to the owner. The GC usually sets an earlier due date for subs.

Who approves a pay application?

Depending on the contract, the architect, the owner or owner's rep, and on financed jobs the lender or its inspector.
