Let me tell you about the $47,000 payment application that got rejected three times.
A plumbing contractor I work with submitted his monthly pay app like he always did — rough numbers, minimal backup, sent via email two days before the deadline. The GC kicked it back for insufficient documentation. He resubmitted with more detail. Kicked back again — wrong format. Third time, he was late, and the GC moved his payment to the next billing cycle.
Three months of waiting for a payment he'd earned because his application process was sloppy.
This doesn't have to be you.
I've reviewed thousands of payment applications over my career, and I can tell you exactly what separates apps that get paid immediately from ones that get stuck in approval purgatory. Let's walk through the process step by step.
What Is a Payment Application?
A payment application (or pay app) is your formal request for payment for work completed during a billing period. On commercial construction projects, it's typically a standardized document — often using AIA G702/G703 forms — that shows what work you've completed and how much you're owed.
Think of it as your invoice's more sophisticated older sibling. While a simple invoice might work for small residential jobs, commercial projects require this detailed, structured approach.
The Anatomy of a Successful Pay App
Every strong payment application includes these elements:
Cover Sheet (G702)
This summary page shows your contract amount, work completed to date, retainage held, and the amount you're requesting. It's what the GC and owner look at first.
Schedule of Values (G703)
This detailed breakdown shows every line item from your contract, what percentage is complete, and the dollar value for each. It's the supporting documentation for your cover sheet.
Backup Documentation
This varies by project but typically includes daily logs, delivery tickets, inspection reports, certified payroll (for public projects), and photographs of completed work.
Lien Waivers
Most GCs require a conditional lien waiver for the current payment and an unconditional waiver for the previous payment before releasing funds.
Step-by-Step: Submitting Your Payment Application
Here's the process I recommend to every subcontractor I work with:
Step 1: Know Your Billing Cycle
Every project has a billing cycle — typically monthly, with applications due on a specific date (like the 25th of each month). Mark this date on your calendar with reminders starting a week before.
Step 2: Track Work Daily
Don't wait until the end of the month to figure out what you've completed. Track progress daily. Note what was installed, tested, or inspected. Take photos.
Step 3: Calculate Percentage Complete
For each line item in your schedule of values, estimate the percentage complete. Be honest but not conservative. If work is 70% done, bill for 70% — not 60% "to be safe."
Step 4: Gather Your Backup
Collect all supporting documentation: daily reports, test results, delivery tickets, inspection sign-offs. Missing backup is the number one reason pay apps get rejected.
Step 5: Complete the Forms
Fill out your G702 and G703 (or equivalent forms). Double-check your math. Triple-check it. Calculation errors destroy credibility.
Step 6: Submit On Time
Submit at least 2-3 days before the deadline. Late applications typically get pushed to the next billing cycle — that's 30 more days of waiting.
Step 7: Follow Up
Don't assume silence means approval. Follow up within 48 hours to confirm receipt and ask if anything's missing.
Common Payment Application Mistakes
After years of reviewing pay apps, these are the errors I see most frequently:
Overbilling
Claiming 90% complete when work is clearly 60% done. GCs catch this, and it damages your credibility for future applications.
Underbilling
Being too conservative leaves money on the table and hurts your cash flow. Bill accurately for what's complete.
Missing Documentation
No backup = delayed payment. It's that simple.
Wrong Forms
Some GCs have specific form requirements. Using the wrong template means starting over.
Math Errors
Nothing tanks credibility faster than pay apps where the numbers don't add up.
Late Submission
Miss the deadline, miss the payment cycle.
Poor Quality Photos
Blurry photos, photos without context, photos that don't clearly show the work — all problems.
Working with the Schedule of Values
Your schedule of values is arguably the most important document you'll create at project start. It sets the billing framework for the entire job.
Front-Load Strategically
You want early line items to carry slightly more weight. Mobilization, submittals, material procurement — these happen early and should be valued appropriately.
Break Down Large Items
A single line item for "$500,000 - Electrical Work" is impossible to bill against incrementally. Break it into phases, floors, or systems.
Match the GC's Format
If the GC has a preferred breakdown structure, follow it. Makes approval easier.
Get It Approved Early
Don't wait until your first pay app to submit your schedule of values. Get it approved during project kickoff.
Retainage: The Money You Can't Bill
Most commercial contracts hold back 5-10% of each payment as retainage — money you don't get until project completion (or substantial completion of your scope).
Your pay app needs to track this separately. Show the retainage being held, and when it's time to bill for retainage release, submit a specific application for that amount.
Pro tip: Some contracts allow retainage reduction after 50% completion. Read your contract and request reduction when eligible.
Digital vs. Paper Applications
More GCs are moving to digital pay app systems like Textura, Procore, or GCPay. If your GC uses one of these:
Learn the system before your first application. Watch tutorials, practice with a test submission if possible.
Understand the approval workflow. Know who reviews at each stage.
Keep backup copies of everything. Digital systems crash. Have PDF exports ready.
What Happens After Submission
Here's the typical approval flow after you submit:
GC Review (5-10 days)
The project manager reviews your application, checks percentages against field observations, verifies backup documentation.
Owner Review (5-10 days)
For projects with owner involvement in approvals, your pay app goes up the chain.
Payment Processing (7-30 days)
Once approved, the owner pays the GC, and the GC pays you. This timeline varies by contract.
Total time from submission to payment: typically 30-45 days on commercial projects.
Using Technology to Streamline Pay Apps
This is where modern tools like SubPaid make a real difference. Instead of manually tracking percentages, gathering backup, and filling out forms from scratch each month:
Track progress digitally throughout the month. Photos, notes, and measurements are captured in real-time.
Auto-generate pay apps based on tracked progress. The math is done for you.
Submit digitally with all backup attached. No chasing down paper documentation.
Track approval status in real-time. Know exactly where your pay app is in the approval process.
The subcontractors I work with who use digital tools spend about 2 hours per month on pay apps instead of 8-10 hours. That's time back in your pocket.
Frequently Asked Questions
What if my pay app gets rejected?
Ask specifically what needs to be corrected. Fix it immediately and resubmit. Document the rejection and your response.
Can I bill for materials stored off-site?
Sometimes, but it typically requires photos, proof of ownership, insurance coverage, and explicit contract language allowing it.
What if the GC changes my billing amounts?
They should notify you before making changes. If they reduce your billing without explanation, challenge it in writing immediately.
How do I handle disputed work in my pay app?
Bill for it anyway, but note the dispute. Don't leave money on the table while the dispute is resolved.
What's the best way to track percentage complete?
Daily progress photos with notes. Track labor hours per line item. Document material deliveries and installations.
