The waiver is filled in. The amount is not the net due on the cover. You stare back and forth between the printed waiver in your left hand and the screen open to your construction pay app line items, pen hovering above the signature line. A single typo or unapproved deduction can hold up your entire draw for three weeks or longer, so you don’t want to sign off on a number that doesn’t align without documenting the discrepancy first. You pull your printed pay app backup from the manila folder at your elbow to cross-reference every line item.
Cross-reference line items with your pay application backup
You don’t need to do a full audit of every cost right now, but you do need to confirm that every line item you submitted on your pay app is accounted for on the waiver, and that the values match what you submitted. First, pull every submitted change order, material receipt, and timecard associated with the current pay period covered by the waiver. Match each billed line item on your pay app to the amount listed on the waiver, marking any line where the numbers differ, even if the variance is only a few dollars. Common mismatches come from unsubmitted change order adjustments, holdback amounts applied incorrectly, or minor arithmetic errors on either the pay app or the waiver draft. Illustrative example: If you billed $14,200 for framing labor and $7,800 for lumber in your pay app, but the waiver lists a combined $20,500 for those two line items, you are looking at a $1,500 discrepancy that needs clarification before you sign. Even small variances can add up over the course of a project, so don’t dismiss a $100 or $200 difference as not worth addressing, especially if you know the work billed was completed per the project schedule and specifications.

Flag unapproved deductions separately for the general contractor
Once you have all mismatched line items marked, list each one with a short explanation of the difference, and attach copies of supporting documentation like approved change orders or delivery receipts to your submission. You do not need to argue the value right away, but you do need to make it clear that the amount listed on the waiver does not reflect the total amount you believe is owed for the pay period. If the discrepancy comes from a previously unmentioned back charge, request written documentation of the work or cost the back charge applies to before you move forward with signing. This gives the general contractor’s team the chance to correct an administrative error before you sign, which often resolves the discrepancy in a matter of hours rather than delaying the entire draw for everyone on the project. Many accounting teams process dozens of pay apps a week across multiple projects, so simple oversights are common and rarely intentional.
Document mismatched values for your internal records
Keep a running log of every discrepancy you find for the current pay period, so you have a clear paper trail to reference if the issue is not resolved before your next draw submission. The table below captures the core details you need to track for each mismatched line item:
| Line item description | Pay app listed amount | Waiver listed amount | Discrepancy value | Supporting doc reference |
|---|---|---|---|---|
| Framing labor | $14,200 | $13,100 | -$1,100 | Change Order #47, approved 10/12/2024 |
| Pressure-treated lumber delivery | $7,800 | $7,400 | -$400 | Delivery receipt #8291, dated 10/03/2024 |
| Window flashing installation | $3,200 | $3,200 | $0 | N/A |
Save a copy of this log in your project folder alongside the unsigned waiver, a copy of the submitted pay app, and all supporting documents, so you can pull it up immediately if the general contractor follows up with questions about the mismatched numbers. You can also reference this log when you submit your next pay app to make sure any outstanding discrepancy is added as a line item on that submission if it is not resolved in the current draw. Keeping clear, organized records of these mismatches also makes it easier to reconcile your project budget at the end of each month, so you can track exactly how much you are owed across all active projects at any given time.
Add a conditional note before you sign the waiver
If you choose to sign the waiver to move forward with processing the amount that is agreed on, add a short, clear handwritten note directly on the waiver document next to the listed amount that explicitly states the sign-off only applies to the agreed portion of the payment, and that you reserve the right to collect the remaining disputed amount at a later date. Make a copy of the signed, annotated waiver for your own records before you send it back to the general contractor, so you have proof of the conditional note if there is a question about the remaining amount later. You can also include a copy of the discrepancy log you created when you send the waiver back, so the general contractor’s accounting team has all the information they need to review the disputed amount without requesting additional paperwork from you. You can upload a scan of the annotated waiver and discrepancy log to Draw Jacket for secure, cloud-based storage that is accessible from any job site device if you need to reference it mid-conversation with a project manager. This step eliminates the need to carry physical copies of every pay document with you when you are moving between job sites, which cuts down on lost paperwork and delays in responding to questions.
When you reopen this page to confirm payment posts
Next time you pull up this page, you will have confirmation of the amount that posted to your account for the current draw, so you can compare the deposited amount to both the waiver value and the original pay app value to see if the discrepancy was resolved as part of this payment. If the deposited amount matches the value listed on the waiver, you can pull your discrepancy log to follow up with the general contractor’s accounting team about the remaining disputed amount, attaching the same supporting documents you gathered earlier to make the review process as fast as possible. If the deposited amount matches the original pay app value, you can update your log to mark the discrepancy as resolved, and file all documents in your closed pay period folder for future reference. You can also note any adjustments you need to make to your next pay app submission to avoid similar mismatches, like including copies of approved change orders directly on the face of your pay app so the accounting team does not miss those adjustments when they draft the waiver for the next pay period. Taking this small step when you submit each pay app cuts down on the number of discrepancies you have to resolve over the course of a project, which saves you hours of administrative work every month and keeps your cash flow consistent. You can also use this check-in to note any recurring issues with waiver values from a specific general contractor’s accounting team, so you can adjust your submission process to include extra supporting documents for all future pay apps to that team, reducing the risk of repeated mismatches.
