The 8% Revenue Bump Hiding in Your Service Agreements

If you run service agreements—maintenance contracts, membership programs, whatever you call them—you're probably billing monthly.

First of the month. Every month. 12 billing cycles per year.

Here's a simple change that adds 8.3% to that revenue: bill every 4 weeks instead of every month.

The Math

There are 52 weeks in a year.

52 weeks ÷ 4 weeks = 13 billing cycles

Monthly billing = 12 cycles. Four-week billing = 13 cycles.

That's one extra billing cycle per year. Same customer. Same service. 8.3% more revenue.

Real Numbers on a Real Book

Same customers. Same service calls. Same cost to deliver. Pure profit increase.

Scale that up. If you have 800 members, it's $23,200. At 1,200 members, it's nearly $35,000.

Why Customers Don't Notice

"Every 4 weeks" feels the same as "monthly" to most people. They're not doing the math.

When someone signs up for a $29 membership and you tell them it bills every 4 weeks, they hear "$29 a month." That's how they process it.

The difference only becomes visible if they pull up their credit card statement and count—which almost nobody does.

Gym chains have been doing this for 20+ years. It's proven. It works.

"Is This Shady?"

It's only shady if you hide it. Don't.

Your contract should clearly say "bills every 28 days" or "bills every 4 weeks." That's the deal. They sign it. It's transparent.

If a customer asks, tell them: "We bill every 4 weeks so your tune-up schedule stays consistent. It's 13 billing cycles per year instead of 12."

Most people will shrug. The ones who do the math and don't like it probably aren't your ideal customers anyway.

The Profit Leverage Effect

Here's what makes this so powerful: the extra 8.3% drops almost entirely to the bottom line.

You're not adding labor. You're not adding materials. You're not adding overhead. The marginal cost of that 13th billing cycle is basically zero.

If your service agreement program runs at 40% margin normally, that extra 8.3% in revenue converts at close to 100% margin.

How to Implement This

For new customers: Just change your membership agreement to say "bills every 4 weeks" instead of "bills monthly." Start tomorrow.

For existing customers: This is trickier. You probably can't change their terms mid-contract without consent. Wait until renewal, or offer a small incentive to switch.

In your billing system: Most payment processors support this. Stripe, Square, ServiceTitan—they all have "every X days" as a billing option. It's a settings change.

For your CSRs: Train them to say "bills every four weeks" naturally. Not "bills monthly." Not "bills thirteen times a year." Just "every four weeks."

What About Churn?

The data from gym chains shows no measurable difference in churn rates between monthly and 4-week billing.

People cancel memberships because they don't see value—not because of billing cycle timing. If your maintenance program is delivering, they stay. If it's not, they leave. The billing frequency is noise.

Why This Matters for Cash Flow

Beyond the annual revenue bump, 4-week billing also smooths out your cash flow.

With monthly billing, you get one big deposit on the 1st. Then nothing for 30 days. Your cash position swings.

With 4-week billing, customers are distributed across different billing dates. The deposits are smaller but more frequent. More predictable. Easier to manage.

Start With New Sign-Ups

You don't have to change everything overnight. Just update your agreement for new customers. In 12 months, a meaningful chunk of your book will be on the new billing cycle.

It's one change. One setting. 8% more money.
