The 9-Line Payment Application

Detailed explanation of each line in the AIA G702 payment application

9 linescalculationg702paymentformulamath

The "9 lines" on the AIA G702 form calculate your payment request step by step. Understanding each line helps you verify your pay applications and communicate effectively with GCs about billing.

The 9-Line Structure

Each line builds on previous lines to arrive at your current payment due. Here's exactly what each line represents and how it's calculated.

Line 1: Original Contract Sum

This is the total value of your signed contract before any change orders. This number never changes throughout the project - it's locked at the original contracted amount.

FieldValue
Example$500,000.00
SourceYour signed contract
Changes?Never - this is fixed

Original vs. Current

Line 1 always shows the original amount. The current contract sum (with change orders) appears in Line 3.

Line 2: Net Change by Change Orders

The sum of all approved change orders, whether additions or deductions. This can be positive (additions exceed deductions) or negative (deductions exceed additions).

FieldValue
FormulaSum of all approved change orders
Example+$25,000.00 (two COs: +$40,000 and -$15,000)

Approved Only

Only approved change orders appear in Line 2. Pending or rejected change orders do not affect this amount. Including unapproved COs will cause your pay app to be rejected.

Line 3: Contract Sum to Date

Your current total contract value, combining the original contract with all approved change orders.

FieldValue
FormulaLine 1 + Line 2
Example$500,000 + $25,000 = $525,000.00

Line 4: Total Completed and Stored to Date

The cumulative value of all work completed and materials stored from project start through this billing period. This comes directly from your G703 grand total (Column G total).

FieldValue
SourceG703 Column G Grand Total
IncludesPrevious work + This period + Materials stored
Example$200,000.00

Line 5: Retainage

The total retainage being held on your completed work and stored materials. Typically calculated as a percentage of Line 4.

FieldValue
Formula (typical)Line 4 x Retainage Percentage
Example (10%)$200,000 x 10% = $20,000.00

Complex Retainage

Some contracts have different retainage rates for work vs. materials, or reduce retainage after reaching 50% completion. RIVET handles these scenarios automatically (requires Pro or Scale plan).

Line 6: Total Earned Less Retainage

The amount you've earned that's actually payable (not being held as retainage).

FieldValue
FormulaLine 4 - Line 5
Example$200,000 - $20,000 = $180,000.00

Line 7: Less Previous Certificates for Payment

The cumulative amount previously certified for payment (what's been approved on all prior pay applications). This is Line 6 from your previous pay app.

FieldValue
SourcePrevious Pay App Line 6
Example$120,000.00

First Pay App

On your first pay application (Application #1), Line 7 is always $0.00 since there are no previous certificates.

Line 8: Current Payment Due

This is the amount you're requesting for this billing period - the bottom line of your pay application.

FieldValue
FormulaLine 6 - Line 7
Example$180,000 - $120,000 = $60,000.00
MeaningAmount you are requesting this period

Line 9: Balance to Finish, Including Retainage

How much of your contract remains to be billed, including the retainage being held. This tells you how much revenue is still to come.

FieldValue
FormulaLine 3 - Line 4
Example$525,000 - $200,000 = $325,000.00
IncludesRemaining work + Held retainage

Complete Example

Here's a full example showing all 9 lines for Application #3 on a project:

LineDescriptionAmount
1Original Contract Sum$500,000.00
2Net Change by Change Orders$25,000.00
3Contract Sum to Date$525,000.00
4Total Completed and Stored to Date$200,000.00
5Retainage (10%)$20,000.00
6Total Earned Less Retainage$180,000.00
7Less Previous Certificates$120,000.00
8Current Payment Due$60,000.00
9Balance to Finish, Incl. Retainage$325,000.00

Verification

You can verify: Line 8 + Line 7 + Line 5 + Line 9 should equal Line 3 (the current contract sum). In this example: $60,000 + $120,000 + $20,000 + $325,000 = $525,000.

Common Calculation Errors

Line 7 Mismatch

The most common error is Line 7 not matching the previous application's Line 6. This happens when updating previous applications without recalculating subsequent ones. RIVET prevents this by maintaining the chain automatically.

Retainage Calculation

Manually calculating retainage often leads to rounding errors. When different rates apply to work vs. materials, mistakes are even more common. RIVET calculates these precisely.

Change Order Timing

Including pending (not yet approved) change orders in Line 2 is incorrect and will cause rejection. Only approved COs belong in your payment calculations.

Automatic Verification

RIVET validates all calculations before generating your pay application, catching errors before they reach the GC.
