AIA Pay Applications and the Schedule of Values Explained

Progress billing on commercial work runs on three pieces of paper that have to reconcile to the penny: the schedule of values, the G703 continuation sheet, and the G702 summary certificate. If any one of them drifts, the check does not move. I have spent 14 years watching small commercial shops learn this the hard way, and the pattern is almost always the same. The mechanics get treated as an accounting formality when they are actually the operating discipline that decides whether payroll clears on the 15th.

An invoice tells a customer what you did and what they owe. A pay application is a certified document package that tells an owner, an architect, and often a construction lender that a specific dollar amount of contracted work has been physically completed as of a specific date, that stored materials are on site or in a bonded warehouse, and that retainage has been calculated at the contract rate. The check does not cut on your word. It cuts on the architect's stamp on the G702's Certificate for Payment block.

That is the reason accounting software alone does not produce a valid pay application. QuickBooks can bill. It cannot certify. On AIA contracts the certification chain is baked into A201-2017 §9.2, and the G702/G703 pair exists to make the certification mechanical rather than argumentative.

The three documents feed each other in one direction. The schedule of values (SOV) is signed once at the beginning of the job and becomes the source of truth for the entire contract sum. The G703 continuation sheet is the working document you update every period, one line per SOV item, showing what was completed previously, what was completed this period, what materials are presently stored, the running percent complete, and the balance to finish. The G702 is the summary certificate that rolls up the G703 totals, applies retainage, subtracts prior payments, and produces the amount due this application.

If the G703 line totals do not exactly match what the G702 summary says they match, the packet comes back. That reconciliation is the whole game.

The SOV is drafted in pencil with the owner and architect before the first pay app is filed. Standard columns are item number (usually CSI MasterFormat), description of work, scheduled value, work completed with prior and current subcolumns, materials presently stored, total completed and stored to date, percent complete, balance to finish, and retainage. Once the schedule is approved, the values are locked. Every subsequent pay application draws against those line values.

The single biggest failure mode is frontloading, which is loading extra dollars into the early line items (mobilization, demolition, submittals) so the contractor collects more cash before the middle of the job. Owners' reps read for this on the first submission. When they catch it, they redline the schedule and hand it back, which delays the first draw and poisons the relationship for the rest of the project.

Owners on r/Construction consistently describe another version of the same problem: two GCs will look at the same contract and produce completely different SOV breakdowns because there is no shared convention on granularity, so each contractor invents one and then has to defend it against an owner who wants it split differently. If you tie each SOV line item back to the underlying estimate, the frontloading question answers itself and the owner's rep has less to argue with.

The G703 has nine functional columns, labeled A through I.

• Column A: Item number. Matches the SOV.
• Column B: Description of work. Matches the SOV.
• Column C: Scheduled value. Locked from the SOV.
• Column D: Work completed from previous applications. Equals last period's Column G total.
• Column E: Work completed this period. The only column that requires field judgment each cycle.
• Column F: Materials presently stored (not already reflected in D or E). Photo proof and, on some contracts, off-site insurance certificates are required.
• Column G: Total completed and stored to date (D + E + F), with a subcolumn showing percent complete (G ÷ C).
• Column H: Balance to finish (C minus G).
• Column I: Retainage. Held at the rate stamped on the application. On variable-retainage contracts (10% early, 5% after 50% complete), Column I is the audit trail that shows the reviewer you calculated correctly.

G703 column totals become G702 summary lines. There is no forgiveness in the arithmetic.

The G702 has nine numbered lines:

1. Original contract sum. Locked from the contract.
2. Net change by change orders. Fed by the Change Order Summary in the lower left, which lists every approved CO with its number and value.
3. Contract sum to date (1 + 2).
4. Total completed and stored to date. Equals G703 Column G grand total.
5. Retainage. Sum of 5a (retainage on completed work) and 5b (retainage on stored materials), reconciled against G703 Column I.
6. Total earned less retainage (4 minus 5).
7. Less previous certificates for payment. Prior draws collected.
8. Current payment due (6 minus 7).
9. Balance to finish, including retainage (3 minus 6).

Below the numbers sits the Contractor's signature, the notary block, and the Architect's Certificate for Payment. The architect's stamp is what actually releases the funds. Notice that Line 1 and Line 2 stay separate for the life of the job, so the original contract sum and change order value never blur into a single number. That separation matters when you close out and the owner asks how much the contract actually drifted.

An approved change order becomes its own contract line with its own number. It does not get folded back into an existing SOV item. The Change Order Summary on the G702 lists CO-001, CO-002, and so on, each with its dollar value, and the sum feeds Line 2. The G703 also gets new rows for each CO with its own scheduled value and its own percent complete. This is why the G702 subtotals original contract separately from change orders: the owner wants to see at a glance what has drifted from the signed number.

Stored materials go in G703 Column F only with photo dates and, on many contracts, off-site insurance riders. Skip either and Column F gets zeroed on review.

Lien waivers move alongside the pay app: conditional waivers for the current period (they take effect once the check clears) and unconditional waivers for the prior period (proof the last draw was received and released). Owners on r/Construction repeatedly describe change orders arriving weeks or months after the work, or clients refusing to pay for unforeseen conditions, and that scope-changing-faster-than-paperwork gap is the single most avoidable reason a G702 fails certification.

From 14 years of customer conversations, roughly 14% of manually prepared G702/G703 pay applications in a typical small commercial shop come back for arithmetic or formatting errors: total mismatches between the G703 grand total and G702 Line 4, retainage miscalculations, unapproved change orders in Line 2, missing lien waivers, or a signature block that a notary flagged. Every rejection tacks another 30 or more days onto an already long payment cycle.

Retainage is the other high-friction category. Owners on r/Construction and Quora consistently describe firms holding it wrong, clients retaining past practical completion, and subs chasing amounts months overdue. The recurring detail in those threads is that nobody has one place showing what is being held and when it is scheduled to release.

A reviewer on Capterra put it directly: the G702/G703 progress billing feature is a lifesaver for their electrical division on bigger commercial jobs, because they can pull AIA-formatted pay apps without rebuilding them from scratch every month. The word rebuilding is the tell. That is what manual preparation actually is.

Progress billing is monthly on almost every commercial contract, tied to a draw schedule the GC set with the owner or lender before the job started. The rhythm is: cutoff on the 25th, submit by the 30th, architect certifies inside two weeks, owner pays inside another two to four weeks, GC pays the sub on pay-when-paid terms.

The industry number worth staring at: CFMA data and specialty-contractor 10-K filings peg commercial subcontractor DSO at roughly 83 days on average, well above the 60-day all-industry benchmark. From 14 years of customer conversations with small commercial shops, owners tell us that 83 days is the structural reality of retainage plus multi-tier pay-app approvals. The lever that actually moves cash is at the front of the cycle: clean G702s, faster lien waivers, and instant resubmits when a reviewer redlines.

Retainage itself is held once at the rate stamped on each application and released once, usually at final completion after the punch list closes. A reviewer on Capterra told us that managing multi-phase commercial builds used to mean juggling spreadsheets and paper logs, and that consolidating everything to one screen cut hours off the weekly admin grind. Any system that can handle scheduling, dispatch, and invoicing from one screen collapses the cycle time between work completed and pay app filed.

AIA G702 and G703 are not free. A single-use license runs $49.99, and the annual AIA Documents Online subscription is $2,199.99. ConsensusDocs 292, 293, and 710 are the main contract-family alternatives and are accepted by many owners. Some GCs will accept a styled equivalent produced by billing software, provided the columns, retainage math, and certification block match the AIA layout exactly.

Where software actually earns its keep is upstream of the form: tying every work order under a project back to its phase, so the percent complete on each G703 line has an audit trail in field data rather than a project manager's memory. When Column E is defensible, the reviewer has nothing to redline.
