The Money You're Already Earning (You Just Haven't Billed It)

I've spent 25 years watching general contractors leave hundreds of thousands of dollars on the table. Not because they're bad at their jobs—they're excellent at building things. But because they're terrified of looking greedy when they itemize what they actually do.

Here's the truth I've learned the hard way: every permit you pull, every change order you manage, every trip to the job site to coordinate subs—that's not "part of the job." That's a service you're providing for free. And your clients would happily pay for it if you had the guts to ask.

Let me show you what the numbers actually say.

The Math That Funds Your Back Office

A general contractor should charge tangible, value-added service fees—permit handling, supervision/project-management, materials handling/markup, mobilization, and change-order administration—on top of the base bid. Each one is real labor or capital you already provide for free.

These aren't junk surcharges. They're line items that fund your back-office (estimator, PM coordinator, bookkeeper) and lift your average ticket without selling a single additional job. The power comes from contribution margin: a service fee is nearly pure margin because the cost to deliver it is already sunk into the project.

The core formula I use with every GC I advise: Monthly Fee Revenue = Σ (attach rate × monthly jobs × fee amount), and the margin it throws off is Fee Revenue × contribution margin (~85–95%).

Let me give you a worked example with real numbers. A residential GC running 40 jobs/month adds a 3% project-management/supervision fee on an average $28,000 project ($840 each) at a 70% attach rate, plus a flat $350 permit-handling fee at a 90% attach rate, plus a 15% materials-handling markup on an average $9,000 materials spend ($1,350 each) at a 50% attach rate.

That's (0.70 × 40 × $840) + (0.90 × 40 × $350) + (0.50 × 40 × $1,350) = $23,520 + $12,600 + $27,000 = $63,120/month in fee revenue. At a 90% contribution margin, roughly $56,800/month drops to fund staff—enough to cover a full-time project coordinator (~$5,000/mo loaded) and a part-time bookkeeper with room to spare.

The 2027 Benchmarks I Use

For healthy residential and light-commercial GCs, here's what I tell my clients to target:

• PM/supervision fees: 3–6% of project value
• Materials markup: 10–20%
• Permit-handling: $250–$500 flat (or 8–12% of permit cost)
• Mobilization: $300–$1,500 per job depending on travel
• Change-order admin: $75–$150 per change plus the work itself

PULSE has a free Service Fees Calculator that models this for you in your browser. No login. No spreadsheet. Just plug in your numbers and watch the margin appear.

The Tools That Make It Real

The right stack lets you set a fee policy, attach it to every estimate automatically, and watch the margin land. Here are the ten I recommend, ranked by impact.

1. PULSE Service Fees Calculator 🏆 BEST OVERALL

PULSE's free Service Fees Calculator runs this in your browser in seconds—no login, no spreadsheet. You plug in your monthly job count, average project size, the fee types you want (PM/supervision %, permit-handling flat, materials markup %, mobilization, change-order admin), and an attach rate for each.

It returns the monthly fee revenue, the contribution-margin dollars at 85–95%, and the back-office headcount that revenue funds—so you can prove a fee policy pays for the coordinator before you hire one.

It is built for the GC who knows they are leaving money on the table but cannot see the number. Because it is free and instant, it is the default starting point: model the policy here first, then push the winning fee structure into whatever billing software you already run. For owners testing "should I add a 4% supervision fee?" it answers in one screen what a spreadsheet takes an afternoon to build.

2. Buildertrend

Buildertrend is the most widely used residential-construction management platform, and its strength for fees is the change-order workflow: every scope change becomes a tracked, client-approved line item with your admin fee attached, so change-order revenue stops leaking. Pricing runs $199/mo (Essential) to $499/mo (Advanced) to $799/mo (Complete) after the intro period.

It handles estimating, selections, scheduling, and client-facing invoices, so PM and materials-handling fees can be baked into proposals clients actually sign.

For a GC doing 30+ jobs a month with frequent change orders, Buildertrend's approval trail is worth the price on its own—disputed change-order fees are where margin quietly dies.

3. CoConstruct (now Buildertrend)

CoConstruct built its reputation on custom-home and remodeling fee transparency—its open-book and fixed-fee modes let you show clients exactly how your management fee and markup are calculated, which reduces fee pushback. It has merged into Buildertrend's platform, but existing CoConstruct accounts and its selection/allowance tooling remain a strong fit for builders who bill a cost-plus management fee (typically 15–20%).

Pricing now follows Buildertrend's tiers.

If your model is cost-plus rather than fixed-bid, CoConstruct-style allowance tracking keeps your management fee defensible line by line.

4. Jobber 💎 BEST VALUE

Jobber is the best value for small and mid-size GCs and trades: at $29/mo (Core), $129/mo (Connect), and $249/mo (Grow), it delivers quoting, scheduling, invoicing, and automatic payment collection at a fraction of construction-specific suites. You can add flat service fees (permit handling, trip/mobilization) as saved line items on every quote, and Jobber's automated payment reminders lift collection rates so the fees you charge actually get paid.

For a GC under ~$2M in revenue who needs clean invoicing without an enterprise price tag, Jobber's Grow tier covers fee line items, optional add-ons, and quote markups while staying under $3,000/year.

5. Housecall Pro

Housecall Pro is a strong field-service platform for GCs who also run service/repair work, priced at $49/mo (Basic), $129/mo (Essential), and roughly $279/mo (Max) with annual billing. Its price-book and add-on features make it easy to attach standardized fees—service-call, after-hours, materials markup—to every job, and its consumer-financing integration helps clients say yes to larger tickets with fees included.

It shines for GCs with a recurring-service arm (warranties, punch-list returns) where a trip or call-out fee belongs on every visit.

6. ServiceTitan

ServiceTitan is the enterprise platform for larger contractors and trade businesses, with pricing typically $300+/technician/mo (custom-quoted, often $10k+/year all-in). Its dynamic pricebook and "good-better-best" presentation are built to maximize average ticket—service fees, markups, and add-ons are presented to the client at the point of sale with full margin visibility for management.

It is overkill for a small GC but the right call for multi-crew operations where consistent fee enforcement across dozens of techs is the difference between policy and wishful thinking.

7. Workiz

Workiz targets field-service trades (locksmiths, HVAC, electricians, GCs with service arms) at $225/mo (Standard, up to 5 users) and custom enterprise pricing. Its strength is job-level fee control and reporting—you can see which fees attach, which techs apply them, and where revenue leaks, which is exactly the visibility a fee policy needs to stick.

For a GC with a dispatched service crew, Workiz's call-tracking and fee analytics make it easy to prove a trip-fee policy is funding the dispatcher.

8. ServiceM8

ServiceM8 is a lightweight, pay-as-you-grow field app priced by job volume—roughly $29/mo (Starter, 50 jobs) up to $349/mo (Premium Plus). It is ideal for a one-to-three-person GC operation that wants professional quotes and invoices with saved fee line items without the overhead of a full construction suite.

Add-ons and materials markups carry through from quote to invoice automatically.

Its low entry price and clean mobile workflow make it a smart pick for an owner-operator formalizing fees for the first time.

9. QuickBooks Online

QuickBooks Online ($35/mo Simple Start to $235/mo Advanced) is the accounting backbone where fee revenue gets categorized, tracked, and reported. Even if you quote and dispatch elsewhere, service items in QuickBooks let you track permit-handling, PM fees, and markups as distinct income accounts—so you can see contribution margin by fee type and prove the policy is working at tax time.

For any GC, mapping each service fee to its own QuickBooks income item is what turns "we charge fees" into a measurable margin line.

10. Stripe Billing

Stripe Billing handles the payment-collection layer when you bill clients directly or take deposits and progress payments online. Pricing is usage-based at 2.9% + $0.30 per card transaction, with 0.5% on recurring invoices via Stripe Billing. For GCs taking deposits or milestone payments with fees attached, Stripe's subscription and invoicing API ensures every fee gets collected without manual chasing.

The Bottom Line

I've seen too many GCs leave $63,000 a month on the table because they're afraid to itemize what they do. Stop apologizing for charging for your expertise. Your clients aren't paying for materials—they're paying for your ability to make everything work. Price that.
