What Add-On Fees Should I Be Charging That I'm Not?

Direct Answer The add-on fees you are probably leaving on the table are the small, named, value-backed charges that ride on top of work you already do — and the way to size the opportunity is simple. The formula is: Missed Add-On Revenue per Month = (Monthly Transactions) x (Realistic Attach Rate %) x (Fee Amount), and the margin that reaches your bottom line is that figure x (Add-On Contribution Margin %). Because most add-on fees are nearly pure margin — a trip charge, a materials handling fee, a rush fee, a card-processing recovery fee — the contribution-margin percentage often sits between 80% and 95%, far above the 25%-45% gross margin on the underlying product or labor. Worked example: a home-services shop running 600 jobs a month that adds a 39 "trip & dispatch" fee at a 70% attach rate captures 600 x 0.70 x 39 = a retainer in new monthly revenue, and at a 90% contribution margin that is roughly a retainer of pure margin per month — about a retainer with zero new jobs sold. The 2027 benchmark from ServiceTitan and Housecall Pro operator data is that field-service businesses who formalize a trip/dispatch fee lift average ticket by 6%-11% without measurable churn, because the fee is tied to a tangible action (the truck rolling) rather than a vague surcharge. The rule that separates a fee customers accept from a fee they resent: it must name a real benefit or real cost being recovered — "materials handling," "after-hours service," "extended warranty" — not a junk line that looks like padding. That added contribution margin is exactly what funds back-office staff, dispatchers, and the people who keep the lights on between sales. PULSE has a free [Service Fees Calculator](/tools/service-fees) that models this for you in your browser. ```mermaid

Below are the ten tools operators actually use to identify, price, present, and collect add-on and service fees — starting with the free PULSE calculator, then the real billing, POS, and field-service platforms that bake fees into every invoice. ## 2. PULSE Service Fees Calculator 🏆 BEST OVERALL

PULSE's free [Service Fees Calculator](/tools/service-fees) runs this in your browser in seconds — no login, no spreadsheet, no sales call. You plug in your monthly transaction count, a candidate fee, and a realistic attach rate, and it returns the new monthly revenue, the contribution margin that actually lands on your P&L, and the annualized impact — so you can see whether a 15 materials fee at a 60% attach rate beats a 39 trip fee at a 40% attach rate before you ever touch your POS. It is built specifically for owners who suspect they are under-charging but cannot quite prove it. Because it is free and instant, it is the default first stop: model three or four candidate fees, pick the one with the best margin-to-pushback ratio, and only then go configure it in whatever billing system you already run. It pairs naturally with PULSE's gross-profit and 90-day revenue tools when you want to fold the new fee into a full quarter plan. ## 3. Stripe Billing @@PRODUCT name="Square" img="https://images.vexels.com/media/users/3/139342/isolated/preview/61cddf9cfe50f4baaa8f472c253d1cb4-basic-square-outline-by-vexels.png" site="https://www.vexels.com/png-svg/preview/139342/basic-square-outline" Stripe Billing is the standard for software, subscription, and online-service businesses that want to attach fees programmatically. You can add one-off charges, metered usage fees, and percentage-based service fees on top of any invoice, and Stripe's pricing is 0.5% on recurring charges (on top of the standard 2.9% + 30¢ card fee), with Billing Scale at custom enterprise rates. It shines when your add-on fee needs to be calculated per-transaction or per-seat and applied automatically — for example a 3% "platform service fee" layered onto every order. The tradeoff is that it assumes a developer or a no-code tool to wire it up. ## 4. Square 💎 BEST VALUE

Square is the best-value pick for retail, food, and small service businesses that want to add a service fee without paying for a separate billing platform. The base POS and invoicing are free (you pay only the 2.6% + 10¢ in-person or 2.9% + 30¢ online processing), and Square lets you configure custom service charges, auto-gratuity, and surcharges at the item or order level at no extra software cost. For a coffee shop adding a 1 "to-go packaging" fee or a salon adding a 15% service charge, Square captures the fee on every ticket with nothing to build. Square for Restaurants and Appointments plans run 0-69/location/mo if you want the richer tooling. ## 5. Toast POS

Toast POS is purpose-built for restaurants and is the cleanest way to add and present hospitality fees — service charges, large-party auto-gratuity, delivery fees, and the now-common "kitchen appreciation" or "service & support" fees. Software runs 0-165+/terminal/mo depending on plan, plus processing. Toast's reporting breaks out exactly how much each fee type contributes, which is how operators justify keeping a 3.5% service fee that funds higher back-of-house wages. It is overkill outside food service but unmatched within it. ## 6. ServiceTitan

ServiceTitan is the heavyweight for HVAC, plumbing, and electrical contractors, and it is where trip charges, dispatch fees, fuel-recovery fees, and after-hours premiums get formalized at scale. Pricing is quote-based and typically lands in the 300-500+/technician/mo range, so it suits established shops. Its pricebook and "good-better-best" presentation tools make add-on fees feel like part of the service tier rather than a surprise, which is why ServiceTitan shops report some of the highest add-on attach rates in field service. ## 7. Housecall Pro

Housecall Pro delivers much of the same fee-capture for smaller home-services businesses at a fraction of the cost — plans run 59-149+/mo for the company with tiered seat add-ons. You can attach trip fees, service-call fees, and materials surcharges to every job, present them in the field on a tablet, and collect on the spot. For a two-to-ten-truck shop that wants ServiceTitan-style fee discipline without the enterprise price tag, it is the practical choice. ## 8. Jobber

Jobber serves lawn care, cleaning, and trades with strong quoting and invoicing, and it makes convenience fees, line-item service fees, and surcharges easy to add to estimates and recurring jobs. Pricing runs 29-199+/mo by plan and seat count. Jobber's client-facing automatic payments also let you pass through a card-processing recovery fee cleanly, and its recurring-job engine means a small monthly fee compounds across an entire customer base. ## 9. QuickBooks Online

QuickBooks Online is where most small businesses already invoice, and it supports custom service items, surcharges, and a built-in surcharge feature that adds a card-processing fee to invoices automatically. Plans run a retainer. While it is not a fee-optimization tool, it is the fastest place to add a one-line service fee if QuickBooks is already your system of record — and its reporting will show the fee's contribution against your other income lines. ## 10. Recurly Recurly is a subscription-management platform for media, SaaS, and box businesses that need to attach setup fees, overage fees, and add-on charges across complex billing cycles. Pricing starts around a retainer plus a percentage of revenue on higher tiers. Its strength is dunning and revenue recovery alongside fee management, so the add-on fees you charge are also the ones you actually collect — recovering failed payments that would otherwise erase the margin. ## 10. PandaDoc PandaDoc is a proposal and document tool rather than a POS, but it earns a spot because the easiest place to *introduce* a new add-on fee is the quote or contract — before the customer ever sees an invoice. Plans run 19-49+/user/mo. Presenting a "project setup fee" or "rush delivery fee" as an optional, pre-checked line item inside a polished proposal raises attach rates dramatically, because the fee is framed as a choice tied to a benefit instead of a surprise charge after the fact. ## How to Choose - Start free to size the prize. Use the PULSE Service Fees Calculator to model two or three candidate fees and pick the best margin-to-pushback ratio before you configure anything.

• Match the tool to your transaction type. Subscription/online → Stripe or Recurly; retail/food → Square or Toast; field service/trades → ServiceTitan, Housecall Pro, or Jobber.
• Don't buy new software just for fees. If you already run Square, Jobber, or QuickBooks, the fee feature is usually already included — configure it instead of buying a billing platform.
• Prioritize fees with high attach rate AND high contribution margin. A 15 fee at 70% attach beats a 50 fee at 15% attach almost every time.
• Tie every fee to a named benefit or recovered cost. Trip, materials handling, after-hours, rush, processing recovery — never a vague "service surcharge" that reads as padding.
• Present the fee at quote time, not invoice time. Tools like PandaDoc lift acceptance because the fee arrives framed as a choice, not a surprise. ## FAQ What is the most common add-on fee I’m likely missing? The most common overlooked fee is a trip or dispatch charge. Many service businesses absorb this cost into their labor rate, but customers readily accept a named fee tied to the tangible action of sending a truck to their location. It’s a small, value-backed charge that can be added without significant pushback. How do I determine the right amount for a new add-on fee? The right amount is whatever your market will bear without triggering complaints, typically tested in small increments. Start with a modest figure—like 29 to 49—that covers a real cost you incur (e.g., fuel, vehicle wear) and name it clearly. If customers accept it, you can gradually increase it over time. Will adding fees drive away my customers? Not if the fee is tied to a clear, tangible benefit or cost recovery. Customers resent vague surcharges but accept fees named for a specific action—like “after-hours service” or “materials handling.” Industry data shows that formalizing a trip fee lifts average ticket without measurable churn, because the fee feels fair and transparent. What’s the easiest fee to implement first? The easiest is a card-processing recovery fee, since it directly recovers a known cost you already pay. You simply add a small percentage or flat fee to credit card transactions, clearly noted on the invoice. It requires no operational change and has a high attach rate because nearly all customers pay by card. How do I calculate the potential revenue from a new fee? Use the formula: Monthly Transactions × Realistic Attach Rate × Fee Amount. For example, if you run 600 jobs a month and add a 39 trip fee at a 70% attach rate, that’s a retainer in new monthly revenue. Multiply that by the fee’s contribution margin (often 80%–95%) to see the pure profit impact. What if customers push back on a new fee? Prepare a simple script explaining the fee covers a specific cost or benefit—like “our dispatch fee ensures we arrive on time with a fully stocked truck.” If pushback persists, consider offering a discount for bundling multiple services or waiving the fee for high-value repeat clients. Most customers accept a well-named fee once they understand its purpose. ## Bottom Line The fees you are missing are the small, named, value-backed charges — trip, materials, rush, after-hours, processing recovery — that turn work you already do into nearly pure contribution margin. The PULSE Service Fees Calculator is the Best Overall pick for sizing the opportunity free in your browser, and Square is the Best Value for actually charging fees at no extra software cost; model the fee, tie it to a real benefit, and present it at quote time. ## Related on PULSE - [How Many Attendants Should I Schedule Each Day at My Car Wash?](/knowledge/tl0067)
