Part-Time or Full-Time Remote Assistant? How to Choose Between 20 and 40 Hours

One of the first questions leaders ask when they consider a remote assistant is also one of the most practical: how many hours do I actually need? Most remote assistants work one of two patterns. Part-time usually means around 20 hours a week. Full-time usually means around 40 hours a week. Both can be dedicated to you, both can be managed well, and both can grow with you. The right choice depends on your work, not on a rule of thumb.

This guide walks through a simple way to decide, the schedule patterns that make each option work, and the signs that it's time to change. It's written for founders, executives and managers who want a sensible answer rather than a sales pitch.

Start with the work, not the hours

The most reliable way to size a role is to measure the work you'd hand off. For one ordinary week, keep a simple task log. Every time you do something that someone else could do with instructions, write down:

• What the task was
• How long it took
• How often it happens
• Whether it needed a live response or could have waited a few hours
• Which tools it involved

Don't try to be perfect. A rough log of a typical week is far better than a guess. At the end of the week, add up the hours and group the tasks into categories: inbox, calendar, travel, CRM and data, documents, research, finance admin, customer follow-up and so on.

Then add two things the log won't show. First, the work you'd delegate if you had help but currently skip: proactive follow-ups, cleaning up the CRM, documenting processes, preparing meeting briefs. Second, a buffer for questions, learning and ad hoc requests, especially in the first couple of months.

A simple sizing rule

Once you have a total, a rough rule works well for most leaders:

• Under about 12 hours of delegable work, with little that needs a live response: start part-time, around 20 hours a week. The extra hours give room for the work you've been skipping and for the assistant to learn your systems.
• Between about 12 and 20 hours, much of it time-sensitive: either can work. Part-time works if the urgent items cluster at predictable times; full-time works if they arrive all day.
• More than about 20 hours, or several people sharing one assistant: start full-time, around 40 hours a week, so the assistant isn't constantly deciding what to drop.

These aren't hard thresholds. They're a starting point for a conversation, and the first 60 to 90 days will tell you whether you chose well.

When part-time is the better choice

A part-time assistant is not a lesser version of a full-time one. For many leaders it's the best fit. Part-time tends to work well when:

• You're a solo founder or a small team whose admin load is real but not yet heavy.
• Your needs are concentrated. For example, inbox triage and scheduling every morning, or a weekly batch of CRM updates and reports.
• You want to test the working relationship before committing to more hours.
• The work doesn't need someone available all day. Many tasks can be done in a focused block and reviewed later.
• You're adding a specialist alongside an existing assistant, such as a part-time bookkeeper or CRM administrator.

The main limitation of part-time is availability. A request that arrives after the assistant's block ends will usually wait until the next day. That's fine if everyone expects it, and a problem if they don't. Clear norms about what waits and what doesn't solve most of this.

When full-time is the better choice

A part-time or full-time assistant gives you breadth and availability. Full-time tends to work well when:

• Your work needs live responses through the day, such as answering calls, handling same-day schedule changes or keeping a sales calendar full.
• Several leaders share one assistant, each with their own requests.
• The role combines two areas, such as executive support plus operations, or appointment setting plus CRM upkeep.
• You're growing quickly and want the assistant to absorb new work as it appears.
• There's a backlog to clear, such as a neglected CRM, months of uncategorized receipts or an overdue recall list.

The main risk with full-time is under-use. A part-time or full-time assistant without enough clear work will either wait for instructions or invent tasks. Before the first day, prepare a list of at least a couple of weeks of real, ready-to-go work, and plan which areas you'll hand over next.

Making the hours work: schedule patterns

How you place the hours matters as much as how many there are. A few patterns that work well with remote assistants in Southeast Asia and Latin America:

The morning launch (part-time). The assistant works the few hours before your day starts. You log on to a triaged inbox, a confirmed calendar and a short brief. With an assistant in the Philippines, that block falls in their evening, which many people prefer to a full night shift.

The overlap block (part-time). The assistant works the first half of your day, when most scheduling and quick questions happen. Assistants in Mexico and Colombia share much of the US working day, which makes this pattern easy.

The full-day overlap (full-time). The assistant works your business hours. Nearshore assistants do this on a normal daytime schedule; Philippine assistants do it on a night shift, a long-established pattern in that country's business-services sector.

The extended day (two assistants). A nearshore assistant covers your day and a Philippine-based part-time assistant covers early mornings or evenings. This works well for teams that need coverage beyond a single shift.

Whatever pattern you choose, write down which time zone the schedule follows. The Philippines doesn't observe daylight saving time, and most of Mexico stopped in 2022, so the overlap with US time zones can shift by an hour when US clocks change in March and November.

Setting up a part-time role for success

Part-time assistants need slightly different habits from both sides:

• Front-load context. A good "how I work" document and a few short screen recordings help someone with fewer hours learn faster.
• Leave a note at the end of your day. Two or three lines with priorities for the next block saves the assistant time and avoids guesswork.
• Batch requests in a shared task list, with due dates, rather than scattered chat messages.
• Define the urgent few. Agree on the small set of things that can't wait, and what happens when one arrives outside the assistant's hours.
• Protect a short live check-in once or twice a week in the first month.

Setting up a part-time or full-time role for success

Part-time or full-time assistants need direction and room to own work:

• Give them clear ownership areas, not just a queue of tasks.
• Protect focus time. If you're available all day, it's tempting to send every thought as it occurs. Batch non-urgent requests.
• Agree on decision rights so they can act on routine matters without waiting for you.
• Plan the next areas to hand over, so growth is deliberate.
• Use an end-of-day note to keep progress visible without micromanaging.

Signs it's time to change

Hours aren't permanent. Review them at 30, 60 and 90 days, and then quarterly. Signs a part-time role should move toward full-time:

• A growing list of tasks you've stopped delegating "because there isn't time."
• Recurring work regularly spilling into the next day.
• You keep needing help during hours the assistant doesn't work.
• The assistant does great work but never gets to the improvements they've suggested.

Signs a part-time or full-time role might be oversized:

• Regular stretches of waiting for instructions.
• Work spread thinly across the day that could be done in a focused block.
• A scope that hasn't grown in months despite strong performance.

If you change hours, update the scope of work, the scorecard and your communication norms at the same time. A change in hours is really a change in role.

Thinking about cost honestly

It's natural to compare options on cost, and you should. But the real comparison isn't part-time versus full-time; it's the cost of each option against the value of the time it gives back to you and your team. A part-time assistant who handles your inbox and calendar can free up hours of a leader's week. A part-time or full-time assistant who keeps a sales calendar full or clears a finance backlog can change what the whole team gets done.

Use your own figures. Estimate the hours you'll get back and what you'd do with them, and compare that with written quotes for the hours you need. Our guide to measuring assistant ROI and the article on the cost of not delegating explain simple ways to do this. Whatever you choose, look for terms that let you change hours as your needs change.

A worked example

A founder of a small consulting firm logs a week and finds about nine hours of delegable work: inbox triage, scheduling client calls, preparing proposal templates and chasing signed engagement letters. Almost none of it needs a live answer. She starts with a part-time assistant in the Philippines working a four-hour block before her day begins. After two months, she has added CRM updates and invoice preparation, and the block is full. At the 90-day review they agree to move to a full-time schedule, with the extra hours overlapping her afternoon for same-day client requests.

Frequently asked questions

Is a part-time remote assistant still dedicated to me?

It can be. A dedicated part-time assistant works only on your tasks during their hours, learns your preferences and builds context over time. Ask any provider whether part-time assistants work for other clients and how that's handled.

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

Usually, yes, and it's a common path. Agree in advance how hours can change, how much notice is needed and whether the same assistant can take on the extra hours.

How many hours does an executive assistant usually need?

It depends on the leader. A single executive with a moderate calendar often fits a part-time schedule of around 20 hours a week. Executives with heavy calendars, frequent travel or several stakeholders often need full-time support of around 40 hours a week.

What if my workload is seasonal?

Discuss it up front. Some teams keep a part-time or full-time assistant year-round and use quieter months for projects; others agree on planned changes in hours for busy seasons.

Do part-time assistants work fixed hours?

They should. A consistent block each day makes planning easier for both sides and helps the assistant build a sustainable routine.
