A brokerage firm effects securities trades and may introduce, execute, clear, carry, advise, or deal. Learn how to verify its role, costs, and protections.
A brokerage firm is a business that effects securities transactions for customers and may provide related account, execution, clearing, custody, financing, research, or recommendation services. In the United States, a securities brokerage firm generally operates through a registered broker-dealer, but its exact role can differ by transaction and service.
The customer-facing brand is not always the entity that carries the account, holds customer assets, clears trades, executes orders, or provides investment advice. Those roles may be performed by one firm, several affiliated firms, or independent service providers.

One legal entity can occupy several boxes. The point of the map is to identify functions and evidence, not to assume every account uses a chain of separate firms.
Under U.S. federal securities law, a broker generally effects securities transactions for other people’s accounts, while a dealer generally buys and sells securities for its own account as a business. A Broker-Dealer can perform either role.
| Capacity or label | What it means | Common evidence |
|---|---|---|
| Broker capacity | Firm acts as agent to effect or arrange a customer’s trade | Order, routing record, execution report, commission, and confirmation |
| Dealer capacity | Firm acts as principal and is the customer’s counterparty | Quote, inventory record, transaction price, markup or markdown, and confirmation |
| Brokerage firm | Business providing brokerage access or services | Form BD, BrokerCheck, Form CRS, customer agreement, and service disclosures |
| Registered representative | Individual registered through a securities firm for specified activities | Form U4-derived BrokerCheck record and firm association |
| Investment adviser | Firm or person providing securities advice for compensation within the applicable definition | Form ADV, IAPD record, advisory agreement, and Form CRS |
The firm’s capacity should be identified for the specific activity. A broker-dealer registration does not mean every trade is principal, and describing a firm as a brokerage does not establish that every communication is a recommendation.
An introducing firm develops or maintains the customer relationship and can accept customer instructions while using a carrying firm for defined account and transaction functions. Its agreement with the carrying firm allocates responsibilities, but the allocation does not make customer-facing obligations disappear.
The executing entity fills the order or arranges execution at a market center. The customer-facing brokerage can execute internally, route to an exchange, alternative trading system, market maker, or another broker-dealer, or use different routes by product and order type.
A clearing firm performs defined post-trade processing. A carrying firm maintains customer accounts and records and performs responsibilities assigned under the carrying arrangement. Clearing, carrying, custody, and settlement are related but should not be treated as interchangeable labels without reviewing the actual agreement.
FINRA Rule 4311 requires covered carrying agreements to allocate specified responsibilities between introducing and carrying firms. Customer documents and statements should help identify where accounts and assets are carried.
A brokerage firm may trade as principal, make markets, hold inventory, distribute new issues, or participate in underwriting. These activities create pricing, inventory, allocation, and affiliate conflicts that differ from pure agency execution.
Some organizations offer both brokerage and investment-advisory services. The same financial professional may be associated with both businesses, but the capacity, fee, decision authority, and standard of conduct should be clear for each service.
Labels such as full-service, discount, online, mobile, or institutional can describe a service model, but they do not reliably identify the legal entity or operational functions.
| Marketing label | What it often suggests | What it does not prove |
|---|---|---|
| Full-service | Access to representatives, research, recommendations, or broader products | Advisory status, discretionary authority, or superior execution |
| Discount | Lower headline transaction charges or fewer bundled services | Lowest total cost or absence of recommendations |
| Online or mobile | Electronic account opening and order entry | Which firm carries assets, executes orders, or receives routing revenue |
| Institutional | Services designed for professional or large accounts | A single execution, custody, clearing, or regulatory model |
| Self-clearing | Firm performs its own defined clearing or carrying functions | That no affiliate, custodian, depository, or market infrastructure is involved |
Use legal names, registration records, and contracts for classification. Marketing labels are useful only after the underlying roles are known.
Assume a customer opens an account through the North Harbor investing app, an invented example.
The customer should not assume that the technology company holds the securities, that the introducing firm executed the trade, or that SIPC and FDIC protection apply to every balance in the same way. Relevant evidence includes the legal names in Form CRS, BrokerCheck, the account and carrying disclosures, the confirmation, the statement header, and the cash-sweep terms.
The names are fictional. The example illustrates role identification and is not an assessment of any real firm.
Depending on registration, business model, and customer eligibility, a firm may provide:
No firm should be assumed to provide every service. Each product and function can have separate eligibility, disclosure, approval, fee, and risk requirements.
Possible revenue sources include:
| Revenue source | Economic mechanism | Customer review point |
|---|---|---|
| Commission | Explicit transaction charge in an agency trade | Rate, minimum, product, channel, and frequency |
| Markup, markdown, or spread | Dealer buys or sells as principal at a customer price | Capacity, prevailing market, price, and disclosure |
| Brokerage Fee | Account, platform, transfer, wire, or service charge | Current schedule and actual account use |
| Margin interest | Customer borrows against account collateral | Interest rate, benchmark, balance, and liquidation risk |
| Product or distribution payment | Product provider or affiliate compensates the firm | Product cost, alternatives, and recommendation conflict |
| Order-routing economics | Market center or venue provides payment, rebate, or other economics | Routing disclosure, execution quality, and conflict controls |
| Cash-sweep economics | Firm or affiliate earns a spread, fee, or other benefit from cash placement | Customer yield, alternatives, program banks, and protection |
| Advisory fee | Separate advisory business charges for advice or management | Capacity, agreement, assets billed, and included services |
A revenue source is not automatically improper. It identifies an incentive and cost that should be evaluated with service, execution, recommendation, and disclosure evidence.
| Question | Brokerage service | Advisory service |
|---|---|---|
| Core activity | Effecting transactions and providing related brokerage services | Providing ongoing securities advice or portfolio management |
| Customer control | Customer generally approves each transaction unless valid discretion exists | Adviser may advise or exercise agreed discretion |
| Common pricing | Transaction, spread, account, financing, or product-related compensation | Asset-based, fixed, hourly, or another advisory fee |
| Common disclosure | Form CRS, brokerage agreement, fee schedule, confirmations | Form CRS, Form ADV, advisory agreement, fee schedule |
| Governing conduct framework | Regulation Best Interest for covered U.S. retail recommendations plus other broker-dealer duties | Investment-adviser fiduciary framework for the advisory relationship |
Many organizations are dual registrants or have affiliated broker-dealer and adviser entities. Ask which entity and capacity apply before interpreting a recommendation, fee, or conflict.
Broker-dealers that carry customer accounts operate under financial-responsibility and customer-protection requirements. SIPC can become involved when a SIPC-member brokerage firm fails and qualifying customer cash or securities are missing, subject to the statute and current limits.
SIPC does not protect against ordinary market losses, guarantee recommendations, or insure a security’s value. Bank-deposit sweep balances can follow FDIC rules instead, while money-market mutual funds remain securities. Protection depends on the legal entity, account capacity, asset, and program structure.
