How to Pass Through Permit Fees and Fuel Surcharges on Invoices

Pass-through costs are real expenses you incur on behalf of the client. They are not your overhead. They are not your profit. And they are not yours to absorb. When contractors swallow these costs — permit fees, dump fees, fuel surcharges, equipment delivery charges — they quietly erode their margin on every job.

On a $40,000 project, pass-through costs often total $1,200–$2,500. Across a full season of 20 similar jobs, that is $24,000–$50,000 in costs you funded out of your own margin. That gap is worth closing.

What Qualifies as a Pass-Through Cost

A pass-through is any third-party cost you pay on behalf of a specific job that you would not incur if the job did not exist. These include:

• Permit fees: Grading, drainage, irrigation, structure permits — any municipal fee pulled for the project. Common range: $200–$1,200 depending on jurisdiction and project scope.
• Dump fees: Tipping fees for excavated material, debris, and green waste. A $0.75/SF estimate across 400 SF is $300 — real money that belongs on the invoice.
• Fuel surcharges from suppliers: Material suppliers add fuel surcharges on deliveries — typically 3–8% of the material invoice. If your supplier charges it, pass it through.
• Equipment delivery charges: Crane or specialty equipment delivery fees not included in your standard estimate. If a hydraulic plate compactor had to be delivered on a flatbed, that delivery cost goes on the invoice.
• Third-party inspections: Engineering sign-offs, soil tests, or structural inspections required by permit. Bill these at cost.

How to Line-Item Pass-Throughs on the Invoice

List pass-throughs as separate line items below your main scope lines. Label them clearly: "City of Austin grading permit (pass-through at cost) — $485." The parenthetical "pass-through at cost" tells the client you are billing exactly what you paid — you are not marking it up. This framing prevents the question "why are you charging me for a permit you pulled?"

Group them under a section header — "Reimbursable Costs" or "Pass-Through Charges" — so they read as a distinct category from your installed work. This organization signals professionalism and makes the invoice easier to review.

Disclosing Pass-Throughs Before the Job Starts

Clients who see a pass-through cost for the first time on the final invoice are surprised. Clients who were told upfront — "permit fees will be billed at cost, estimated $400–$700 for this project" — are not. The proposal is the right place to set this expectation. Include a line in the proposal's scope section: "Municipal permit fees and site disposal costs billed at actual cost."

This one sentence prevents most invoice disputes over pass-through costs. The client knew it was coming. The invoice is confirmation, not a surprise.

"If a cost exists because of this job, it belongs on this job's invoice."

Should You Mark Up Pass-Throughs?

Some contractors add a 10–15% handling fee on pass-throughs to cover the administrative time of pulling permits, scheduling inspections, and tracking reimbursable costs. This is legitimate. Label it: "Permit fee ($485) + 10% permit management fee ($48.50) = $533.50." Most commercial clients expect this. Most residential clients accept it if it was disclosed in the proposal.

At minimum, bill pass-throughs at cost. Absorbing third-party costs into your overhead is a losing strategy — those costs fluctuate with every job, every city, every season. They cannot be reliably built into your base price. Bill them separately and transparently.

Fuel Surcharges: Your Own and Your Suppliers'

A fuel surcharge is a variable cost that fluctuates with diesel prices. When your supplier adds one to a delivery invoice — typically 4–7% of the material cost — you have two options: absorb it or pass it through. Pass it through. A $6,000 material delivery at a 5% fuel surcharge is $300. Across five deliveries on a large project, that is $1,500 in fuel costs you paid for your client.

Some contractors add their own fuel surcharge for job sites that require significant drive time or multiple mobilizations. If you drive 45 minutes to a site twice a week for three weeks, that fuel cost is real. A flat $75–$150 per mobilization is reasonable on jobs over $10,000. Disclose it in the proposal and it will never be questioned on the invoice.

Frequently Asked Questions

Can I bill clients for permit fees I pulled on their behalf?

Yes. Permit fees are a project cost incurred on behalf of the client. Bill them at actual cost, clearly labeled, as a separate line item. If you add a handling fee for the administrative time to pull and manage the permit, disclose that in the proposal. Most clients have no issue with permit pass-throughs when they are transparent.

What is a reasonable fuel surcharge for landscape contractors?

For your own vehicle and equipment costs, $75–$150 per mobilization is standard for jobs requiring significant drive time. For supplier fuel surcharges passed through directly, bill whatever the supplier charged you — typically 3–8% of the material cost. The key is disclosure: state your fuel surcharge policy in the proposal before the client signs.

What if the permit cost more than my estimate in the proposal?

Bill the actual cost and note the variance: "Municipal grading permit — estimated $400, actual $520 per City of Austin fee schedule." Include a copy of the permit receipt if the client asks. Actual pass-through costs always supersede estimates when you bill at cost — that is the nature of pass-throughs. The proposal should state "permit fees billed at actual cost."

Should I mark up dump fees?

At minimum, bill them at cost. You can add a handling or disposal management fee of 10–15% to cover the time of hauling, weighing, and documenting. Some contractors include dump fees in their per-SF price — which works if you estimate them accurately. But if the actual disposal cost exceeds your estimate, billing at cost with a separate line is always defensible.
