How to set up a schedule of values and submit progress billings without errors

Most billing disputes on commercial jobs trace back to a schedule of values that was never built correctly. Here is what to set up before the first draw is submitted.

A general contractor we work with submitted his second draw request on a $2.1 million office renovation and waited three weeks for approval. The owner’s project manager had rejected the application. Line items were too broad to verify from a site walk. Percentages on the mechanical, electrical, and plumbing (MEP) rough-in scope did not match what the owner’s inspector had observed.

Nothing was wrong with the job. The problem was the schedule of values. It had been drafted in one afternoon before mobilization, using the same rough categories as the bid estimate. At that level of detail, every draw after the first was going to require a negotiation.

What a schedule of values is and why it matters

A schedule of values is the line-item breakdown of the entire contract amount, agreed to by both parties before the first billing period. Every progress billing for the life of the job pulls from that schedule. When the schedule is too broad or its values are front-loaded, the owner’s representative will push back on line items, and the contractor floats the draw balance while revisions go back and forth.

Building a defensible schedule takes two to three hours at the start of a job. Resolving a disputed draw mid-project can take two to three weeks.

Four ways schedules break down

Line items set too broadly. A line labeled “rough framing” for $380,000 gives the owner’s inspector nothing to verify on a site walk. The inspector has to estimate what percentage of framing is complete, and if that estimate differs from what was billed, the draw gets cut. Breaking framing into foundation work, structural walls, and roof structure gives each line a scope that can be observed and confirmed independently.

Mobilization allocated too high. Contractors sometimes assign a larger portion of the contract value to early line items to improve early cash flow. Owners and their project managers are trained to recognize this. A combined mobilization and general conditions line above 8 to 10 percent of the contract value will often trigger a rebalancing request before the first billing cycle.

Billed percentages that do not match the field. The owner’s representative walks the job before approving each draw. If the application shows 75 percent complete on MEP rough-in and the site inspection puts it at 55 percent, the application comes back cut. On a $240,000 MEP scope, a 20-point dispute means $48,000 sitting in review while the contractor waits.

Retainage not tracked separately. Commercial contracts typically withhold 5 to 10 percent of each approved draw until substantial completion. When retainage is not tracked as a separate running total on the schedule, the balance becomes unclear and the final payment conversation starts from uncertain ground.

What the billing looks like in practice

Here is a five-scope schedule for an $825,000 commercial renovation, with Month 3 billing shown.

Line item	Contract value	Billed prior	This period	Total billed	% complete
General conditions	$45,000	$27,000	$9,000	$36,000	80%
Site work and demolition	$60,000	$60,000	$0	$60,000	100%
Concrete and masonry	$180,000	$90,000	$36,000	$126,000	70%
MEP rough-in	$240,000	$72,000	$48,000	$120,000	50%
Finishes and millwork	$300,000	$0	$30,000	$30,000	10%
Total	$825,000	$249,000	$123,000	$372,000	45%

The Month 3 draw is $123,000 before retainage. With 10 percent withheld, the contractor receives $110,700 and $12,300 is added to the retainage receivable on the balance sheet.

Why draw disputes are expensive

A $123,000 draw that takes three additional weeks to approve means the contractor has been carrying that amount on a credit line. At a typical short-term borrowing rate, three extra weeks on a draw of that size costs $400 to $600 in interest. On a 12-month job with monthly draws, delayed approvals add a cost that was never in the original estimate.

When a contractor bills a percentage that exceeds actual completion, the excess appears on the balance sheet as a liability. It represents work paid for but not yet performed. If the project stops before those line items are finished, the overbilled amount has to be returned.

How we handle this for clients

For construction clients we work with, the schedule of values is built before the contract is signed and reviewed against the estimate to confirm no scope is missing. Each line corresponds to a category of work that can be verified from the field. Mobilization is set at a percentage the owner is unlikely to challenge.

As costs come in, they post in QuickBooks against the matching schedule line. At billing time, percent complete is calculated from actual costs versus the estimated total for each line, and a cost-to-date report is attached to every AIA application for payment. Most owner representatives approve faster when the numbers are supported by actual records.

Best practices for clean progress billing

Draft the schedule from the project estimate. Every distinct scope in the estimate should have its own line.
Cap the combined mobilization and general conditions lines at 8 to 10 percent of the contract value. Higher allocations will be questioned by experienced owners and their lenders.
Attach a cost-to-date summary to every draw application. It is not required on most contracts, but it answers the most common questions before they become rejections.
Record retainage withheld as a separate receivable in QuickBooks, not as a reduction in billed revenue. Keep the balance visible on the balance sheet until the project reaches substantial completion.
Add approved change orders to the schedule on the same day they are executed. Billing against an unapproved or unrecorded scope is a common trigger for owner disputes.

Three questions worth asking

Can an owner’s inspector independently verify the percent complete on each line item based on a single site walk, or does every billing require a follow-up conversation to agree on the number?
What is the current retainage balance on each active job, and does that amount appear as a receivable on your balance sheet?
On your last draw application, were any line items cut or sent back for documentation, and what specifically was questioned?

If the answers are uncertain, the schedule of values may not be structured to support billing without friction. The fix is a one-time setup at the start of the next job, not a mid-project overhaul.
