## What it does

The skill walks through how advisory billing works, from the rate schedule to collecting the money and disclosing it to clients. It covers the common models: flat fee, percentage of assets, tiered schedule, hourly and hybrid. The tiered-versus-breakpoint distinction gets its own treatment. Under a tiered schedule each dollar is billed at the rate for the tier it falls in; under a breakpoint the whole balance takes the rate of the highest tier reached. On a large account that gap is real money, so the advisory agreement has to say which one applies.

Valuation is the other half. The skill lays out the usual choices for the valuation date — quarter-end, prior quarter-end, period average — and the edge cases that break billing: held-away assets, accrued bond interest, margin debit, cash the adviser does not manage. Mid-period account openings get proration, and household aggregation combines related accounts so the family reaches a better tier before the fee is allocated back.

Billing cycles run quarterly, monthly or annually, and the skill compares advance billing with arrears. Advance billing creates a deferred revenue liability and needs a refund calculation when an account closes early. It also covers GAAP revenue recognition and fee disclosure. Performance-based fees are the sharp edge here: they require qualified client status under SEC Rule 205-3 and a high-water mark, or a drawdown can get billed twice.

## When to use it
- design a tiered rate schedule across asset levels
- pick a valuation date that matches the advisory agreement
- prorate a fee for an account opened mid-quarter
- decide between advance billing and arrears

# Fee Billing

## Core Concepts

### 1. Fee Schedule Structures

Advisory firms employ a range of fee structures, often combining several within a single practice.

**Flat Fee (Fixed Dollar).** A predetermined dollar amount charged per period regardless of account size. Common for financial planning engagements or retainer-based advice. Straightforward to bill but disconnected from asset growth.

**AUM-Based (Percentage of Assets).** The most prevalent model for registered investment advisers. A single percentage (e.g., 1.00%) is applied to the market value of managed assets. Simple to communicate but can become expensive for large portfolios and cheap for small ones.

**Tiered / Breakpoint (Declining Rate).** A graduated schedule where successive tiers of assets are billed at progressively lower rates. For example:

| Tier | AUM Range | Annual Rate |
|------|-----------|-------------|
| 1 | First $500,000 | 1.00% |
| 2 | Next $500,000 | 0.80% |
| 3 | Next $1,000,000 | 0.60% |
| 4 | Over $2,000,000 | 0.40% |

Under a true tiered schedule each dollar is billed at the rate for the tier it falls within. Under a breakpoint schedule the entire balance is billed at the rate corresponding to the highest tier reached. The distinction matters significantly for large accounts and must be clearly defined in the advisory agreement.

**Flat-Plus-AUM Hybrid.** Combines a fixed planning fee with a lower AUM percentage. Useful for firms that want to be compensated for planning work independently of portfolio size.
