ASO (Administrative Services Only) Benefits Plans – A Simple Explanation

An ASO plan is a "self-funded" benefits plan. Instead of buying insurance for your employees, your company acts as its own insurance provider, and you simply hire an insurance company to do the paperwork.

How it Works (The 3 Pieces)

1. You pay for the actual claims: When an employee goes to the dentist or gets a massage, the money to pay that claim comes directly out of your company's pocket, not the insurance company's.

2. You pay an Admin Fee: You pay an insurance company a small fee to process the receipts, provide the benefit cards, and handle customer service.

3. You buy Stop-Loss (just in case): To protect your company from bankruptcy if an employee needs a $100,000 (or more) medication, you buy "stop-loss" insurance. This covers catastrophic, worst-case scenario claims.

Traditional Insurance vs. ASO

Feature	Traditional Insurance (Fully Insured)	ASO (Self-Funded)
Who takes the financial risk?	The insurance company	The employer
What are you paying for?	A fixed premium based on risk	Actual claims + an admin fee
If claims are low...	The insurance company keeps the profit	The employer keeps the savings
If claims are high...	The insurance company takes the loss (but raises your rates next year)	The employer pays the extra cost out of pocket

Who is this actually for?

ASO plans are not a one-size-fits-all solution. Because the employer takes on the financial risk, they are specifically designed for a certain type of business.

Here is a breakdown of who ASO plans are—and aren't—built for:

The Ideal Candidate: Mid-to-Large Companies

ASO plans are typically recommended for companies with 50 to 100+ employees.

• The Law of Large Numbers: When you have a lot of employees, health and dental claims become highly predictable. You know that out of 100 people, roughly the same amount of money will be spent on dental fillings and prescription glasses every year.

• Financial Buffer: Larger companies usually have the cash flow to handle a "bad month" where claims suddenly spike, without it hurting their core business operations.

Specifically, ASO plans are for employers who:

1. Want to keep the profits: Companies that want to keep the savings when their workforce is healthy, rather than handing that profit over to an insurance company.

2. Want total transparency: Employers who want detailed data on exactly how their benefit dollars are being spent (e.g., how much goes to massages vs. prescriptions).

3. Want to customize their plan: ASO plans allow you to build unique health plans from scratch, rather than picking an off-the-shelf package from an insurer.

Who avoids it? 

Small businesses. If you only have 5 employees, just one person having a bad year of health issues will completely blow up your budget rate. Small businesses usually stick to traditional insurance where the insurance company takes 100% of the risk.

The Bottom Line: With ASO, you are paying a company purely for their administrative services, while you fund the actual health and dental costs yourself.  They’re super efficient and customizable but come with the financial responsibility to fund the health and dental claims.
