Part-Time vs Full-Time Virtual Assistant: How to Choose the Right Hours

"Should I hire part-time or full-time?" is one of the first questions founders ask me, and it is usually asked the wrong way round. People start with a budget or a gut feeling about hours, pick a number, and then try to fit the work into it. The better order is to start with the work, see what shape it has, and let the hours follow.

I run Virtual Assistant Capital, and we place both part-time and full-time virtual assistants, so I have no reason to push you one way. Both are good answers to different problems. This guide explains how to tell which problem you have, what each option really costs per hour and per month, where each one tends to go wrong, and how to move from one to the other without losing the momentum you have built.

The short answer first

If you have a focused set of recurring tasks that adds up to roughly two to four hours a day, and you are still learning to delegate, start part-time. If you already have a full day of work waiting, need someone available through most of your working hours, or want the VA to own a whole function rather than a task list, go full-time.

Everything below is the detail behind that answer.

What "part-time" and "full-time" actually mean for a VA

The labels get used loosely, so it is worth being precise.

A part-time VA typically works a fixed block of hours each week. On our Essentials plan, that is 20 hours a week. In practice this usually means about four hours a day, five days a week, though some founders prefer longer blocks on fewer days. The VA is dedicated to you during those hours, but they are not on call outside them.

A full-time VA works a standard full working week for you. On our Executive and AI Manager plans the VA is full-time and works only on your business. They are around for most of your day, they can take on projects that need sustained attention, and they can become the person who simply knows how things work.

The important word in both cases is dedicated. A part-time VA who is dedicated to you for 20 hours a week is a very different thing from a "shared" assistant who handles a little of your work in between several other clients. Shared models can work for very small, infrequent task lists, but you lose continuity, and continuity is where most of the value comes from.

Start with the work, not the hours

Before you decide on hours, spend twenty minutes listing the work you would hand over. Our delegation playbook walks through this properly, but the short version is: write down every recurring task you did in the last two weeks that someone else could learn, then put a rough weekly time against each one.

Now look at three things.

1. The total

Add up the hours. Be honest, and then add some margin, because founders almost always underestimate how long their own admin takes. A task that "takes five minutes" often takes fifteen once you count finding the file, switching context and checking the result.

If the total sits comfortably under 20 hours a week, part-time is the natural fit. If it is already pushing past 20, or you can see it getting there within a couple of months, full-time is worth a serious look.

2. The timing

Some work can be done at any point in the day. Research, data entry, CRM clean-up, report preparation and content drafts are all like this. A part-time VA can batch them into a focused block and get through a lot.

Other work has to happen when it happens. Inbox triage for a business where clients expect quick replies, live calendar management, answering a support queue, coordinating a team across the day, or being available when you come out of a call and need something done now. Work like this does not batch well. If a large share of your list is time-sensitive and spread across your day, a part-time block will feel too narrow, even if the total hours look small. If the time-sensitive part is mostly phone volume, compare a virtual assistant with a call center before you settle on hours.

3. The depth

Part-time VAs are excellent at well-defined tasks. Full-time VAs can go further: owning a function end to end, running a project over several weeks, building and maintaining a system such as your CRM, or becoming the operational centre that other people on your team rely on.

Ask yourself whether you want help with tasks or someone to own an area. If the answer is "own an area," the hours almost always need to be full-time, because ownership needs context, and context needs time in the business.

When part-time is the right call

Part-time is not the "cheap option." It is the right option in some very common situations.

You are delegating for the first time. Learning to delegate is a skill, and it takes a few weeks to build. Hiring a full-time VA before you have built it often means paying for capacity you cannot yet feed. A part-time VA gives you time to learn what to hand over, how to brief it, and how to review it, without the pressure of filling forty hours.

Your recurring work is focused. If the job is inbox and calendar, a weekly report, CRM updates and some research, that is a well-defined bundle that fits neatly into 20 hours. Our Essentials plan is built around exactly that kind of list.

Most of your work can be batched. If very little of it is urgent in the moment, a four-hour daily block can be more efficient than a full day, because the VA works through a queue with few interruptions.

You want to prove the model first. Some founders have been burned before and want evidence before committing further. Starting part-time and growing into full-time is a perfectly sensible way to build that evidence.

Where part-time goes wrong

The most common failure is underestimating the work. The founder hires for 20 hours, discovers there is really 30, and the VA ends up permanently behind. Everyone feels it: the founder thinks the VA is slow, the VA feels set up to fail, and the backlog grows. If you notice your VA's queue is never empty by the end of the week, that is a capacity problem, not a performance problem.

The second failure is expecting full-time availability from part-time hours. If you message at 4pm and the VA's block ended at 1pm, you will wait until tomorrow. That is not a flaw in the VA. It is the deal. Agree the hours up front, put them in your "how I work" note, and plan around them. Our guide to onboarding a virtual assistant in week one covers how to set that rhythm on day one.

When full-time is the right call

You already have a full day of work. If your task list is well past 20 hours, a part-time VA will just be the bottleneck. Hiring full-time from the start avoids months of an assistant who is always behind.

You need someone present through your day. Founders who live in their inbox, take back-to-back calls, or run client-facing operations usually need their VA working alongside them, not in a separate block. Full-time hours make real-time support possible.

You want ownership, not assistance. A full-time VA can own your client onboarding, your operations calendar, your CRM, or your project coordination. That is a different level of value, because it frees your attention as well as your time. You stop holding the whole thing in your head.

You want workflow improvement, not just workflow execution. This is where our AI Manager plan comes in. An AI-fluent full-time VA does the work, and also looks at how the work is done: which steps can be automated, where an AI tool can do the first draft with a human checking it, and how your CRM and processes can be built to run more smoothly. That kind of improvement needs time and context, which is why we only offer it full-time. More detail is on the AI Manager virtual assistant page.

Where full-time goes wrong

The mirror image of the part-time failure: hiring full-time before you have a full day of work to hand over, or before you know how to hand it over. The VA finishes the obvious tasks by lunchtime and then waits for instructions that do not come. Good VAs will look for things to do, but they cannot read your mind, and an under-briefed full-time hire is an expensive way to feel guilty about delegation.

The fix is not necessarily to downgrade. It is often to go back to your task list and look for the work you have been holding on to. Most founders are sitting on a lot more delegable work than they think, especially follow-ups, reporting, and the "small" admin that adds up to hours. If you genuinely cannot find enough work after a proper look, part-time is the better answer for now.

The cost comparison, done honestly

Here is what our plans cost, published in full on our pricing page:

Every plan has a $0 recruitment fee, a free shortlist of two to three vetted VAs within 72 hours, and you only start paying once your VA starts. Terms are month-to-month, and there is a 30-day replacement promise if the fit is not right.

Two things stand out in that table.

First, full-time is slightly cheaper per hour than part-time on our plans. The reason is simple: a provider's fixed costs of recruiting, vetting, supporting and replacing a VA are similar whether the VA works 20 hours or 40, so the per-hour price falls as the hours rise. If you are already close to full-time in workload, part-time can end up being the more expensive way to buy the same hours.

Second, the right comparison is not part-time against full-time. It is the cost of the VA against the cost of your time doing the same work. If you are spending three hours a day on admin and your own time is worth much more than $10 an hour to the business, either plan pays for itself as long as the work is real. For a wider look at the market, including US-based assistants and where the cheapest options end up costing more, see how much does a virtual assistant cost.

The hidden cost of choosing wrong

The monthly fee is the visible cost. The bigger cost is what I call the restart tax: the time you lose every time you replace a VA and start the onboarding over again. You re-explain the business, re-share the logins, re-record the walkthroughs, and absorb another few weeks of mistakes while the new person learns.

Choosing the wrong hours is one of the quieter causes of the restart tax. A part-time VA who is permanently overloaded burns out or gets blamed and replaced. A full-time VA with nothing to do drifts, disengages and leaves. In both cases the founder concludes that VAs do not work, when really the hours did not match the work. We see this pattern often enough that it appears in our post-mortem on why virtual assistants don't work out.

So the decision is worth a careful twenty minutes, not because the fee is large but because restarting is expensive.

How to move from part-time to full-time without a restart

The good news is that this decision is not permanent if you set things up well. Many founders start part-time and move up as the workload grows, and the transition can be smooth.

Use the same person. The biggest advantage of upgrading rather than re-hiring is that your VA already has the context. Ask early whether they would be open to full-time hours later. With us, moving from Essentials to Executive or AI Manager is a plan change, and plans are month-to-month.

Keep the SOPs current. If your VA has been writing SOPs as they learn each task, which they should be, the extra hours slot in easily. New tasks get documented the same way.

Watch for the signals. It is usually time to move up when the queue is never empty at the end of the week, when you are holding back tasks because "they are already busy," when time-sensitive work keeps waiting until tomorrow's block, or when you find yourself wanting the VA to own something rather than just do it.

Add the new work in batches. Do not double the hours and dump everything at once. Add one new area at a time, give it the same week-one treatment you gave the original tasks, and review closely for the first few days.

Going the other way, from full-time down to part-time, is less common but sometimes right, for example after a seasonal peak or a project ends. Be open about it with your VA and give notice; good people deserve that, and they may know where the real remaining work is better than you do.

A quick decision checklist

Run through these and count your answers.

1. Does your recurring work add up to more than about 20 hours a week?
2. Does a large share of it need doing at specific times through your day?
3. Do you want the VA to own an area, not just complete tasks?
4. Have you delegated successfully before, with written processes or recordings?
5. Do you want someone improving your workflows and tools, not just running them?

Mostly "no": start part-time. Mostly "yes": go full-time. If question five is a clear yes, look at the AI-fluent full-time option. A mix of answers usually means part-time now, with a plan to review at the 60 or 90 day mark.

FAQ

Is a part-time virtual assistant worth it for a small business? Yes, if the work is real and recurring. A focused bundle of inbox, calendar, CRM updates and research can fit well into 20 hours a week, and it is often the best way to learn delegation before committing to more hours.

How many hours a week should my first virtual assistant work? List your recurring tasks with honest time estimates and add some margin. Under about 20 hours a week of mostly batchable work points to part-time; more than that, or a lot of time-sensitive work spread across your day, points to full-time.

Is a full-time virtual assistant cheaper per hour than a part-time one? Usually, yes. On our plans Essentials works out to about $10 an hour for 20 hours a week, and Executive to about $9 an hour for full-time. The provider's fixed costs are similar either way, so the per-hour price falls as hours rise.

Can I start part-time and switch to full-time later? Yes. With us, plans are month-to-month and moving from Essentials to Executive or AI Manager is a plan change. Ideally you keep the same VA, so you do not lose the context they have already built.

Will a part-time VA be available when I need them? During their agreed hours, yes. Outside them, no, and that is the trade-off. Agree the hours in writing on day one and route anything urgent outside that window to someone else or to the next block.

What does a full-time VA do that a part-time VA can't? Mostly, ownership. With full-time hours a VA can run a function end to end, support you live through the day, manage multi-week projects, and, if they are AI-fluent, improve your workflows and systems rather than only operating them.

The short version

Do not pick hours first. List the work, then look at its total, its timing and its depth. A focused, batchable list under about 20 hours a week suits a part-time VA, especially if you are new to delegating. A full day of work, lots of time-sensitive tasks, or a wish for someone to own an area suits full-time. Choosing hours that do not match the work is a quiet cause of failed placements and the restart tax that comes with them, so it is worth getting right. And if you start part-time, set it up so you can grow into full-time with the same person.
