Schedule of Values Guide for Electrical Subs

Every month on billing day, your Schedule of Values determines exactly how much money you can ask for. Not your effort. Not your progress. Your SOV. If a line item is structured wrong, you cannot bill for work you have already completed. If the whole thing is sloppy, the GC kicks back your pay app and you wait another 30 days. For electrical subs running on 10-15% net margins, a poorly built SOV is the fastest way to finance someone else's project with your own cash flow.

The SOV is not just a document the GC requires. It is your billing blueprint for the entire job. Every line item you create before mobilization becomes a row you update, justify, and defend every single month until closeout. Get it right upfront and billing becomes almost mechanical. Get it wrong and you spend the rest of the project fighting over percentages.

What a Schedule of Values Actually Is

A Schedule of Values is a line-by-line breakdown of your total contract price into individual work items. Each line gets a specific dollar value. When you add all the lines together, they equal your contract amount exactly. Not approximately. To the penny.

Think of it as a financial map of your scope. It tells the GC, owner, and architect what you are doing, how much each piece costs, and how to measure your progress. When you submit a monthly AIA pay application, the G703 Continuation Sheet is essentially your SOV in operational form. Each row on the G703 corresponds to a line item from your approved SOV, with columns tracking work completed, materials stored, and percentage complete.

Here is the part many new electrical subs miss: the SOV is not just a GC document. While the general contractor creates the master project SOV for the owner, every subcontractor creates their own SOV for their portion of the work. Your SOV feeds into the GC's master SOV, which feeds into the owner's construction loan draws. If your SOV is inaccurate, it creates a chain reaction. The GC cannot bill the owner, the owner cannot draw from the lender, and nobody gets paid.

Your SOV also supports your mechanics lien rights by creating a clear record of work completed and amounts owed. If you ever need to file a claim, this documentation matters.

What Line Items to Include

The biggest question new subs face is what to put on the SOV. The answer starts with understanding that electrical work spans three CSI MasterFormat divisions: Division 26 (Electrical), Division 27 (Communications), and Division 28 (Electronic Safety and Security). Your SOV should reflect whichever of these divisions fall within your contract scope.

But spec sections alone are not enough. The most effective approach is a phase-based breakdown that mirrors how the work actually progresses in the field. When your SOV lines match your cost codes and your construction sequence, percent-complete claims become easy to defend. You can show the GC your job cost report alongside the pay app and the numbers align.

Here is what a representative SOV looks like for a mid-size commercial electrical project:

The percentages shift based on project type. A data center will weight switchgear and power distribution much higher. A retail buildout will have proportionally more lighting and devices. The key is that each line item represents a distinct phase that can progress independently and be verified in the field.

How many line items is right? More than three and fewer than fifty. A two-line SOV listing just "Labor" and "Materials" gives you zero billing flexibility. You cannot claim rough-in work until the entire labor scope is done. But a 50-line SOV creates administrative overhead every billing cycle and invites the GC to dispute percentages on minor items. For most electrical subcontracts, 7-20 phase-based line items is the sweet spot. Scale up for larger contracts: a $100K job might need 8 lines, while a $2M+ project could warrant 25-35 lines broken out by floor, system, and phase.

Why Your SOV Lines Should Match Your Cost Codes

This is the detail that separates contractors who bill smoothly from those who fight over every pay application. When the GC's superintendent walks the job, you should be able to show your job cost report by phase alongside the G703 by line item. Same numbers. Same structure. No translation required.

If your estimate breaks work into rough-in, trim, and fixtures but your SOV breaks it into first floor, second floor, and third floor, you are going to spend hours every billing cycle trying to map one set of numbers onto the other. And the GC will notice when the percentages do not add up.

Start from your estimate breakdown. If you estimated labor and materials by phase, use those same phases as your SOV lines. The work of breaking down costs has already been done during bidding. Use it.

Front-Loading: Where the Line Is

Front-loading means assigning a disproportionate amount of your contract value to early-phase work items. Instead of distributing overhead and profit evenly across all line items, you inflate early items like mobilization and underground rough-in while reducing the value of later items like trim-out and closeout.

Some degree of front-loading is common and widely accepted. Electrical contractors face real cash flow gaps. You pay for materials, labor, and equipment weeks or months before receiving payment, and retention withholds an additional 5-10% on top of that. Structuring your SOV to recover startup costs early is a legitimate business strategy.

The acceptable range is shifting roughly 3-7% of total contract value from later phases to early ones. On a $1.1M contract, that means moving about $55,000 from back-end items to front-end items. Enough to create a meaningful cash flow cushion without distorting the SOV beyond recognition.

Front-loading crosses the line when mobilization shows up at 15-20% of the contract value (actual cost is typically 3-5%), when billed amounts dramatically exceed visible site progress, or when the back-end items are so undervalued that there is no financial incentive to finish the project. GCs detect aggressive front-loading by comparing your SOV values against their own cost estimates and walking the job site to verify claimed progress.

The smarter approach is transparency. If you have legitimate startup costs, permits, bonds, engineering, shop drawings, long-lead equipment orders, create separate line items for them. A clearly labeled "Mobilization" line at 4% is far more defensible than inflating your underground rough-in by 40%.

Bill for Stored Materials

Stored materials are items you have purchased and had delivered but have not yet installed. The AIA G703 has a dedicated column for them, and most commercial contracts allow you to bill for materials stored on-site before they are incorporated into the work.

This matters enormously for electrical contractors because switchgear, transformers, panelboards, and lighting packages are high-value items that must be ordered 12-16 weeks before installation. A single switchgear order can run $50,000-$100,000+. Without stored material billing, you are financing that inventory entirely out of pocket. Sometimes for months.

To bill stored materials successfully, you need documentation: supplier invoices showing the project name, proof of payment, date-stamped photos of materials clearly labeled and segregated for the project, and insurance certificates. As materials are installed, their value migrates from the "stored" column to the "work completed" column on the G703, so there is no double-billing. Just earlier cost recovery.

Here is the catch: not every GC allows stored materials billing, and some require a specific clause in your subcontract. Check the contract before your first pay application. If you can bill for stored materials and you are not, you are financing the project for free.

What GCs Look for When They Review Your SOV

Understanding the reviewer's perspective helps you build an SOV that sails through approval. GCs evaluate your SOV against specific criteria, and knowing these upfront saves rounds of revisions.

Proportionality is the first thing they check. They compare each line item's dollar value to the expected actual cost of that work. If your numbers look out of proportion, like panel installation valued at 25% of contract when the actual cost is closer to 8%, it triggers immediate pushback. GCs maintain their own cost estimates and use them as a benchmark.

Alignment with contract scope is the second checkpoint. Your SOV line items should map to your contracted work and, where required, to CSI MasterFormat section numbers. A line item labeled simply "Electrical Work" will be rejected because it does not specify what tasks are included, making progress measurement impossible.

Consistency with field observations matters every billing cycle after approval. When a pay app shows 50% of the contract billed while only 20% of work is visibly complete on-site, the GC will dispute the application. This is why phase-based line items that match the construction sequence are so valuable. They make it easy for the GC's superintendent to walk the job and confirm your claimed percentages.

Eight Mistakes That Cost You Money

1. The two-line SOV. Listing "Labor" and "Materials" as your only line items is the most common beginner error. You cannot bill for rough-in completion when your only labor line covers the entire project. Break work into phases that can progress independently.

2. Not matching spec sections. If your contract includes Division 26, 27, and 28 work, your SOV should reflect that structure. Failure to align creates confusion during billing review and change order tracking.

3. Ignoring the construction schedule. If two phases can progress at different speeds, they should be separate line items. An electrical sub billing underground rough-in and above-grade rough-in on the same line cannot show progress on one when the other stalls.

4. Reusing last project's template. No two projects share the same scope, sequencing, or trade breakdown. An SOV template from a warehouse job will not work for a hospital. Start from the contract scope every time.

5. Forgetting change orders. Approved change orders should be added as new line items with their own scheduled value. Failing to update the SOV means you are either not billing for approved extra work or cramming it into existing lines where it distorts percentages.

6. Aggressive front-loading. Loading 15% into mobilization when the actual cost is 4% gets your SOV rejected, damages trust with the GC, and creates a cash crunch at closeout when remaining work has almost no billing value left.

7. Not billing stored materials. The G703 has a dedicated column for it. Materials on your job site represent real cash you have already spent. If your contract permits stored material billing and you are not using it, you are leaving money on the table every month.

8. Manual errors compounding over time. The G703 continuation sheets build on one another. Previous application amounts carry forward. A transposed number in month two compounds through every subsequent billing cycle. On a $1M contract, even a small data entry error rate means tens of thousands of dollars in potential discrepancies.

Getting Your SOV Approved on the First Try

The contractors who get their SOVs approved fastest follow a consistent process:

1. Start from the contract scope. Not a generic template. Identify what divisions and phases define your deliverables.
2. Build line items that mirror both spec sections and construction sequence. Each line should represent a distinct phase that can be independently verified in the field.
3. Match SOV lines to your internal cost codes. When the GC walks the job, your job cost report and your G703 should tell the same story.
4. Align your billing curve with your cost curve. If you spend 40% of your costs in the first half of the job, the first half of your SOV should represent roughly 40% of the contract value.
5. Submit with supporting documentation. Providing backup cost data, even a simple summary of your estimate by phase, demonstrates transparency and accelerates approval.
6. Use the GC's format if they provide one. Do not submit your own template when the GC gives you theirs. Match their format exactly.

One hour negotiating the SOV before mobilization is worth more than ten hours of billing disputes after the fact.

Stop Managing SOVs in Spreadsheets

Excel works until it does not. The limitation is that nothing flows automatically. Labor hours, purchase orders, change orders, and material receipts all require manual entry, and errors compound over time. When you are managing multiple active projects with different billing cycles, it gets messy fast.

Faraday builds your G702 and G703 directly from your job data, tracks percent complete across every line item, handles retention calculations automatically, and keeps change orders organized so billing day takes minutes instead of hours. If your SOV management is eating into your evenings, give it a look. It is built for electrical subs.
