What does ASO amount mean on a benefits invoice, and why does it change each month?

[stellapotter]

We switched to a self-funded benefits plan and keep seeing "ASO amount" on our TPA invoices with no clear explanation. ASO stands for Administrative Services Only — it's the fee your administrator charges to manage claims without providing actual insurance coverage. The variable amounts are confusing our finance team. How do others explain this in internal reporting?

ASO (Administrative Services Only) amount on a benefits invoice is the employer’s cost for claims plus admin fees. It changes monthly based on actual healthcare claims, usage, and enrollment fluctuations.
