SOV stands for Schedule of Values, and it’s the financial backbone of nearly every commercial construction project. It’s a detailed spreadsheet that breaks an entire contract into individual line items, each with an assigned dollar amount, so everyone involved can track how much work has been completed and how much money is owed at any given point. Think of it as a master list that translates a lump-sum contract into measurable, billable pieces.
How an SOV Works
A Schedule of Values takes the total contract price and divides it into specific tasks, phases, or trade categories. Concrete foundations might be one line item, structural steel another, and electrical rough-in another. Each line item gets a dollar value that reflects its share of the total contract. When it’s time to request a payment, the contractor reports what percentage of each line item is complete, and the math flows from there.
This structure makes progress billing possible. Instead of waiting until a building is finished to get paid, contractors submit payment applications each month (or on whatever schedule the contract specifies) showing exactly which portions of work they’ve finished. The SOV is the reference document that makes those requests verifiable. Owners and lenders depend on it to confirm that money is being released only for completed, verified work.
What’s Inside a Typical SOV
Most SOVs follow a standard column layout, whether they’re built in a spreadsheet, construction software, or on the industry-standard AIA G703 Continuation Sheet. The core columns include:
- Item number: A sequential identifier for each line of work.
- Description of work: A clear label for the task or phase, such as “site grading,” “HVAC installation,” or “interior painting.”
- Scheduled value: The dollar amount assigned to that line item. All scheduled values add up to the full contract amount.
- Work completed (previous): The dollar value of work billed in prior payment periods.
- Work completed (current): The dollar value of work finished during the current billing period.
- Materials stored: The value of materials delivered to the site (or stored off-site) but not yet installed.
- Total completed and stored: The sum of all completed work and stored materials for each line item. This number feeds directly into the total payment request.
- Retainage: A percentage (commonly 5% or 10%) withheld from each payment as a financial safeguard until the project is substantially complete.
The header of the document typically includes the project name, project number, address, and contractor name, so there’s no ambiguity about which contract the SOV belongs to.
The SOV and AIA Billing
In the United States, the most widely recognized format for progress billing uses two standardized forms published by the American Institute of Architects: the G702 (Application and Certification for Payment) and the G703 (Continuation Sheet). The SOV is essentially what populates the G703.
The G703 takes each line item from the SOV and tracks its billing history across every payment period. The G702 then summarizes those numbers into a single-page snapshot: total work completed, total retainage held, and the net amount due. When a contractor submits a pay application, they’re updating the G703 line items and generating a new G702. The two forms work together, but the SOV is the foundation underneath both.
Why Front-Loading Is a Red Flag
One of the most common disputes around an SOV involves “front-loading,” where a contractor inflates the dollar values assigned to tasks that happen early in the project. By doing this, they can bill for a larger share of the contract in the first few months, improving their cash flow before the bulk of the work is done.
Owners and lenders watch carefully for this because it creates risk. If a contractor has already been paid 60% of the contract value but only 40% of the actual work is complete, the owner has limited leverage if something goes wrong. The contractor’s surety (the bonding company backing the project) also has a strong interest in preventing overpayment, since they’d be on the hook if the contractor defaults. Common safeguards include capping line items for mobilization, bonds, and insurance at reasonable levels, and requiring that the SOV be reviewed and approved before the first payment is issued.
The flip side is also a problem. If an SOV undervalues early work, the contractor and their subcontractors end up financing the project out of pocket for longer than necessary. This increases what’s known as days revenue outstanding and can create genuine financial hardship down the supply chain.
How Lenders Use the SOV
On projects financed by a construction loan, the SOV plays an even bigger role. Lenders use it to control “draws,” the periodic releases of loan funds that keep the project moving. Before approving each draw, the bank (or a third-party inspector working on their behalf) reviews the SOV alongside the pay application to confirm that the reported progress matches what’s actually built.
This is why accuracy matters from day one. If line items are vague, lumped together, or poorly aligned with the actual scope of work, it creates friction every time a draw is requested. Projects with strict lender oversight benefit from a granular, well-organized SOV because it speeds up the approval process and keeps cash flowing on schedule.
How Change Orders Affect the SOV
Construction projects rarely finish with the same scope they started with. When a change order is approved, it needs to be reflected in the SOV so that billing stays accurate. Typically, approved change orders are added as new line items at the bottom of the existing schedule, each with its own description and dollar value. The total contract amount on the SOV is then adjusted to match the revised contract sum.
Some project management platforms automate this by adding change orders to the SOV as soon as they’re approved. On projects still using spreadsheets, it’s a manual process that requires careful tracking to prevent discrepancies between the SOV, the change order log, and the current contract value.
Building a Strong SOV
The SOV is typically prepared by the general contractor shortly after the contract is signed, then submitted to the owner (and often the architect) for review and approval before the first pay application. Getting it right at this stage saves months of billing headaches later. A few principles make the difference between an SOV that works smoothly and one that causes constant disputes.
Break work into specific, measurable tasks rather than broad categories. “Electrical” as a single line item for a $2 million scope is too vague to track meaningfully. Breaking it into rough-in, panel installation, fixture installation, and final terminations gives everyone a clearer picture of progress. Align line items with how work will actually unfold on site, not just how the estimate was organized. And assign dollar values that genuinely reflect the cost of each task, not strategic guesses designed to accelerate cash flow.
A well-built SOV doesn’t just support billing. It becomes a real-time financial model of the project, showing at a glance how much is done, how much is left, and whether spending is tracking with progress.
