AOR vs EOR: Choosing the Right Model for 1099 Contractors

If you engage contractors at any volume, sooner or later a customer, an auditor, or a board member asks who is responsible for making sure those contractors are engaged correctly. The two standard answers are an agent of record and an employer of record. The names are close enough that people use them interchangeably in meetings. They describe opposite arrangements, and picking the wrong one is expensive in both directions.

First, which "agent of record" we mean

The phrase is overloaded. In advertising, an agency of record is the agency a brand designates to buy its media. In insurance brokerage, an agent of record letter moves an existing policy from one broker to another. If you searched either of those and landed here, this is not your article.

In workforce compliance, an agent of record is a service that sits between a company and its independent contractors. It checks classification before work starts, handles the engagement paperwork and insurance requirements, and keeps the records. That is the meaning used below.

What an EOR does

An employer of record becomes the legal W-2 employer of your worker. It runs payroll, withholds taxes, provides benefits, and carries the employment liability. You still direct the work; the EOR holds the employment relationship. Deel and Remote are the names most people know, and we have written a side-by-side on Deel before.

An EOR is the right tool when the role is actually a job. You want someone forty hours a week, on your schedule, in your systems, maybe in a country where you have no entity. Fine. Employ them, and an EOR does that cleanly.

The cost structure is the catch for contingent work. You pay a monthly fee per worker on top of wages and employer burdens, and the fee is the same whether that person worked five hours or two hundred. The worker also stops being independent, which some of them do not want; freelancers with four clients are rarely eager to become your part-time employee. One talent firm we work with ran this math and wrote up what they found. There is a longer discussion in our EOR alternative page.

What an AOR does

An agent of record leaves the 1099 relationship in place and does the work of making it defensible.

That work is mostly unglamorous. Someone evaluates the engagement against classification criteria before the contractor starts, instead of reconstructing the reasoning two years later during an audit. Someone makes sure there is a signed agreement with a real scope of work. Someone checks that the insurance a client requires is actually in force. And all of it gets filed, because the entire value of the exercise is being able to produce the record when a state agency or an opposing attorney asks for it.

The contractor keeps what made contracting worthwhile: other clients, their own tools, control over how the work gets done. The company keeps documentation showing those things are true.

When W-2 is the right answer

Some roles should not be run through an AOR, and a decent one will tell you so. If your managers set the person's hours, supply the equipment, and direct the work day to day, that is an employment relationship regardless of what the contract says. Paperwork and insurance do not reclassify anyone. The facts of the working relationship decide classification; documentation can only prove the facts, not improve them.

So the two services are not competitors. They are answers to different questions about the same role.

Four questions worth asking per role

Who controls how the work gets done? Is the engagement tied to a project or open-ended? Does the worker have other clients? Do they bring their own skills and tools?

If the answers point at the worker (their methods, project-based, multiple clients, own tools), the role belongs on the contractor track and an AOR keeps it compliant without converting it. If the answers point at you, it is a job, and an EOR will run it properly. The mixed cases are the ones worth a formal determination instead of a gut call, and in our experience the mixed cases are most of them.

How 1099Policy handles it

Our classification determination is a structured questionnaire scored against 38 indicia on an audit-grade rubric, ML-assisted and reviewed by a specialist. Most determinations come back inside 24 hours. The output routes a worker to an IC track, a W-2 track, or a hybrid, and produces a defense file that is versioned, audit-ready, and available over API.

Determinations carry indemnity: $1M by default, with a $5M umbrella available. Eligible contractors then get coverage in their own name for the assignment, spanning workers' comp, general liability, media liability, and E&O, underwritten through a licensed carrier rated A+ (Superior) by AM Best. Workers' comp placement is available in the 46 states with a private market; the four monopolistic states are handled through their state funds.

Determinations are a flat fee per engagement. Insurance is priced per assignment: a premium that is a small percentage of contractor pay, plus a platform fee that is a fraction of a percent of spend. There is no monthly per-worker subscription.

Where that leaves you

If a role is clearly employment, use an EOR and do it properly. If it is genuinely independent work, an AOR makes it provable. If you are not sure which one you are looking at, that is the case a determination exists for.
