Part-Time Virtual Assistant vs Full-Time: Why Many Agencies Say No

Quick answer: A part-time virtual assistant usually works 10 to 20 hours a week, and the easiest places to find one are freelance marketplaces and services that sell assistant hours in monthly blocks. Many dedicated VA agencies, including Stellar Staff, place full-time assistants only, because a full-time role keeps one person focused on your business and gives them a reason to stay. If your work truly fits in 15 hours a week, part-time help is the better fit. If it is closer to 30, full-time usually is.

Why do some virtual assistant agencies only offer full-time staff?

Agencies that place one dedicated assistant with one client usually stick to full-time roles because the work of finding, vetting, and supporting a hire costs about the same whether that person works 20 hours a week or 40. Recruiting, interviews, background checks, payroll, and HR all happen per person, not per hour. A full-time role also changes who applies. Experienced assistants want a steady full-time income, and they may leave a part-time role when a full-time offer comes along. Finally, one client means one schedule and one set of priorities, so the assistant isn't splitting the day between your deadlines and someone else's. The trade-off is simple: the monthly bill is higher, and you need enough work to fill the hours. For many owners with 10 to 15 hours of tasks, that trade-off doesn't make sense yet, and they should look elsewhere.

That is the model at Stellar Staff. Every placement is full-time, 160 hours a month, on either the Pro plan at $1,999/month or the Executive plan at $2,999/month. There is no part-time plan.

We hear the other side of this on sales calls. As one owner put it: "The make or break is finding someone at 20 hours a week or less with specialized skills; other groups are only full time." That is a fair need, and the sections below explain where that help comes from.

How many hours a week counts as part time for a virtual assistant?

There is no single legal definition, and the number changes depending on who is counting. The U.S. Bureau of Labor Statistics counts people who usually work fewer than 35 hours a week as part-time in its labor surveys. The IRS uses a different line for the Affordable Care Act employer rules: a full-time employee averages at least 30 hours of service a week, or 130 hours a month. The Fair Labor Standards Act doesn't define full-time or part-time work at all, so employers generally decide. In the VA market, "part-time" usually means 10 to 20 hours a week or a monthly block of hours, and "full-time" usually means a standard 40-hour workweek with one client. When you compare offers, ignore the label and ask for the actual number of hours you are buying each month and which hours of the day they cover.

If you hire a freelancer directly, the employment questions get more complicated, especially whether that person is a contractor or an employee. Our virtual assistant contract template covers that question and the clauses to put in writing.

Where can you hire a part-time virtual assistant for 10 to 20 hours a week?

Part-time help mostly comes from three places. Freelance marketplaces such as Upwork and Fiverr let you post a job or buy a service and pay by the hour or by the project, but you do the vetting and the management. Job boards for remote workers, such as OnlineJobs.ph, let you hire a person directly and set the hours yourself, which also makes you responsible for screening, pay, and replacement if they quit. Hour-block assistant services sell a set number of hours each month, and the work may be done by one assistant or by a small shared team. Each option can work. The difference is how much of the hiring and management falls on you, and how likely you are to keep the same person month after month. A dedicated full-time agency sits at the other end: more hours, one assistant, and less hiring work on your side.

Is a part-time VA more expensive per hour than a full-time one?

Usually, yes. A part-time VA almost always costs less per month, but the hourly rate tends to be higher. There are a few reasons. A provider's fixed costs, such as recruiting, setting up your account, and running payroll, get spread over fewer hours. Freelancers who work 10 hours a week for you need several clients to fill their own week, so they price each hour to cover the time they spend switching between clients and looking for work. Marketplaces may add service fees on top of the freelancer's rate. Some hour-block plans also let unused hours expire at the end of the month, so a slow month raises your real cost per hour. A full-time role works the other way: a higher monthly bill and a lower cost per hour. At Stellar Staff, the Pro plan works out to about $12.50 an hour. The right question isn't which rate is lower. It's whether you'll actually use the hours you pay for.

For published hourly and monthly rates across marketplaces, hour-block services, and agencies, see our guide to how much a virtual assistant costs. For the difference between hourly, retainer, and monthly pricing models, see virtual assistant pricing and packages.

One cost doesn't shrink with the hours: your own time. Explaining your tools, customers, and standards takes about the same effort for a 15-hour assistant as for a full-time one, and you repeat that work if the person leaves.

What do you give up when your VA also works for other clients?

When an assistant splits the week between several clients, you share their attention, their calendar, and their memory of how things are done. That is often fine for tasks that can wait a day, such as data entry, research, or scheduling social posts. It causes problems for work that needs a fast response or a lot of context, like answering customer emails, managing your calendar, or following up with leads. On sales calls, owners who have used shared or part-time assistants describe the same problems: the assistant isn't available during the hours you need them, response times stretch when another client is busy, details get lost between sessions, and a different person sometimes picks up the work. None of this means part-time help is bad. It means you should decide in advance which tasks can tolerate a delay and which can't.

Before you sign with any part-time provider, ask these questions and get the answers in writing:

• Which hours of the day will the assistant be available, and in which time zone?
• Will the same person handle my work every week?
• Who covers the work if that person is sick or on vacation?
• Do unused hours roll over to next month, or do they expire?
• How many other clients does the assistant support, and who else can see my accounts?
• How much notice do I need to give to cancel?

Why do part-time virtual assistants leave for full-time jobs?

Most of the time, it comes down to income. For many assistants, a part-time role is a way to cover the bills while they look for a full-time position with one steady employer, and when that offer comes, they take it. This isn't unique to the VA market. The Bureau of Labor Statistics reported that 4.5 million people in the U.S. were working part time for economic reasons in September 2026, which means they would have preferred full-time work but had their hours cut or couldn't find a full-time job. The same pull exists for remote assistants in other countries. For you, the risk is timing. An assistant often leaves just as they have learned your systems, which means you start the search and the onboarding over again. One owner told our team that their only VA quit to take a full-time job before the owner had even finished getting her ready to answer the phones.

If you go part-time anyway, offer the same hours every week instead of "whenever there's work," pay on a regular schedule, and write down your processes as you hand them off, so the next person can pick them up faster.

How can you tell whether your workload is closer to 10 hours or 40?

Start with one normal week. Write down every task you or your team did that didn't need your specific skills, and estimate the time each one took. Most owners count the obvious work, such as the inbox or scheduling, and leave out the rest: following up on quotes and unpaid invoices, cleaning up the CRM, updating spreadsheets, researching vendors, preparing reports, and the projects that keep slipping to next month. Then add the work that would happen if someone had time for it, like calling back old leads. That backlog fills slow days for a full-time assistant. If your list still comes to 10 or 12 hours after that exercise, part-time help is a reasonable choice. If it comes to 25 hours or more, a full-time role usually pays off.

When does a full-time VA make sense with fewer than 40 hours of core work?

A full-time virtual assistant can make sense even when your main task takes only 20 or 25 hours a week. The first case is coverage. If the job is answering phones, responding to customer emails, or managing a calendar, you're paying for someone to be available during business hours, not just for the minutes spent on each task. The second case is uneven work. If your volume comes in waves, a part-time assistant can't absorb the busy weeks, while a full-time one can handle the peak and use quiet days for backlog work. The third case is growth. Owners who hire part-time to "start small" often find the assistant has settled into 16 or 20 hours and isn't available when the business needs 40. And one person who works only for you learns your customers and preferences faster.

The test is simple: if you can name the tasks your assistant would do once the core job is finished, full-time is likely worth it. If you can't, wait.

When is part-time help the better choice?

Part-time help is the better fit in several situations, and it's worth being honest about them. Choose part-time if your delegable work is under 15 hours a week and you don't have a backlog to add. It also fits when you need one specialized skill for a few hours a month, such as a monthly bookkeeping close or occasional design work, rather than a general assistant. A seasonal project with a clear end date, like a tax-season rush or a product launch, is another good case for a freelancer. Part-time also makes sense if a full-time monthly plan doesn't fit your budget yet. The last case is time. If you can't set aside time every day to give direction and answer questions, a full-time assistant will run out of work, and you'll feel like you're paying for empty hours. In each of these cases, a marketplace freelancer or an hour-block service is the practical choice, at least for now.

Part-Time VA Questions Owners Ask Before They Hire

How many hours does a part-time virtual assistant work?

Most part-time VA arrangements fall between 10 and 20 hours a week, or a set block of hours each month. There is no legal standard. The BLS counts fewer than 35 hours a week as part-time in its surveys, while the IRS treats 30 hours a week as full-time for health coverage rules. Ask any provider for the exact hours per month.

Can I hire a part-time executive assistant?

Yes. Several virtual executive assistant services sell hour packages, and some experienced EAs freelance for a few clients at once. The trade-off is availability: executive support often means fast replies and calendar changes during the day, which is harder when your EA also serves other people. Our comparison of virtual executive assistant services separates hour-block providers from full-time ones.

Does Stellar Staff offer part-time virtual assistants?

No. Stellar Staff places full-time assistants only, 160 hours a month, on the Pro plan at $1,999/month or the Executive plan at $2,999/month. Plans are month to month and can be canceled with 14 days' notice. If you need fewer hours, a marketplace freelancer or an hour-block service is likely a better fit.

How much does a full-time VA cost?

It depends on where the assistant is based and how you hire. Through Stellar Staff, a full-time assistant costs $1,999/month on the Pro plan, about $12.50 an hour, or $2,999/month on the Executive plan. Freelancers and other agencies publish a wide range of rates, which we compare in our virtual assistant cost guide.

Is it cheaper to hire a part-time VA than a full-time one?

Per month, yes. Per hour, usually not. Part-time rates tend to be higher because fixed costs and the assistant's time between clients are spread over fewer hours, and marketplace fees or expiring hour blocks can add more. Compare what you'll pay per hour you actually use, not just the monthly total.

Is a monthly or an hourly VA plan better?

An hourly plan suits light, irregular work, because you pay only for what you use. A monthly plan suits steady work, because the hourly rate is usually lower and the same person keeps learning your business. If your hours vary a lot from month to month, start hourly and track your usage for a few months before you commit.

Can I start part-time and move to full-time later?

You can with some freelancers and hour-block services, but it doesn't always go smoothly. An assistant who has built a schedule around 15 or 20 hours for you may already have other clients and may not be able to take on more. If you expect to need a full week within a few months, it's often simpler to hire for that role from the start.

Match the Model to Your Weekly Hours, Not the Monthly Bill

Choosing between a part-time virtual assistant and a full-time one comes down to hours and continuity. With 10 to 15 hours of work and nothing waiting behind it, a freelancer or an hour-block service is a practical choice. With 25 hours or more, a need for coverage during business hours, or a history of assistants who leave, a full-time assistant who works only for you is usually the better fit.

A VA of any kind is also the wrong choice in some cases. If the work must be done in person, needs a U.S. license, or requires decisions only you can make, keep it in-house. If you can't spare time each day to give direction, fix that first, or any assistant will struggle. For the full cost comparison with a local employee, see virtual assistant vs employee cost.

If full-time fits your workload, you can review the plans on our pricing page or start the search on our hiring page.
