If you've ever typed 'do I need a VA or an OBM' into a search engine, you're not alone. For founders of growing service businesses, this is one of the most common and most confusing hiring decisions they face.

The job titles sound similar. The descriptions overlap. And the internet is full of people telling you that what you need is whichever one they happen to offer.

So let me try to cut through it all. In this post, I'm going to explain what each role actually does, where the differences lie, and most importantly how to figure out which one your business actually needs right now.

I should say upfront: I'm a Fractional COO and Operations Director. But I also don't promote any specific platforms and I'm people-first in how I work, which means I'll tell you honestly if what you need is something different to what I offer.

First, why does this matter?

Hiring the wrong kind of support is one of the most common reasons founders end up still feeling like the bottleneck in their own business.

I spoke recently to a founder who had hired VAs more than once. Capable people, willing to help but she still felt like she was carrying everything. Every task needed briefing from scratch. Nothing moved without her. She was starting to wonder whether she needed someone more senior, someone who could take more ownership.

But here's the thing: the problem wasn't the level of the hire. It was that there was nothing for anyone to work from. No documented processes. No clear task ownership. No system that meant work could be handed over without a full briefing every time.

In that situation, no hire however experienced will fix the underlying issue. Because the issue isn't the person. It's the structure.

Understanding the difference between a VA, an OBM, and a Fractional COO helps you identify not just who to hire, but what needs to be in place first.

What is a Virtual Assistant (VA)?

A VA executes tasks. They're skilled, often highly capable, and typically work across a range of tools and platforms. They do what you ask them to do and do it well.

Common VA tasks include:

Admin and inbox management. Keeping on top of emails, scheduling, travel bookings, and day-to-day correspondence.

Social media scheduling. Creating graphics from templates, scheduling posts, and responding to comments.

Research. Pulling together information, comparing options, compiling reports.

Data entry and CRM management. Keeping records up to date, logging contacts, processing information.

Tech support. Setting up tools, managing platforms, handling basic technical tasks.

When a VA is the right choice

A VA works well when you have specific, repeatable tasks that are clearly defined and easy to hand over. If you know exactly what you need done and you just need someone to do it, a VA is often the most cost-effective and practical solution.

The key word is defined. A VA needs to be directed. They work best when the process is clear and the task is bounded.

When a VA won't solve the problem

If your issue is that you don't know how to hand things over (because the process only exists in your head, or because you haven't yet built the system that would make delegation possible) a VA will not fix that. You'll spend more time briefing than you save.

What is an Online Business Manager (OBM)?

An OBM manages. Where a VA executes, an OBM takes ownership of delivery including coordinating people, projects, and processes on your behalf so you don't have to be the one holding everything together.

Common OBM responsibilities include:

Team management. Overseeing VAs or contractors, delegating work, and making sure things get done.

Launch management. Planning and coordinating the moving parts of a launch — emails, content, tech, team — so the founder can focus on showing up.

Project management. Keeping projects on track, chasing actions, and making sure deadlines are met.

Systems implementation. Setting up tools and workflows from a brief or plan, often with a good understanding of common platforms.

When an OBM is the right choice

An OBM is a strong fit when you have a team to manage, recurring launches to run, or a complex delivery process that needs someone to coordinate it. They're particularly valuable when the strategy is clear and the founder needs someone to own the execution.

When an OBM won't solve the problem

An OBM manages what's already there. If the systems don't exist yet (if there's no clear operational structure for them to manage) they'll struggle to create it from scratch. OBMs are implementation-focused, not architecture-focused. And if you're looking for someone to tell you what needs building, as well as build it, an OBM may not be the right fit.

What is a Fractional COO?

A Fractional COO, or Fractional Operations Director, which is the more widely used term in the UK, works at a strategic level. They don't just execute tasks or manage delivery. They look at the whole operational picture, identify what's not working, and build the systems and structure that will allow the business to grow without everything depending on the founder.

The word fractional means part-time or project-based. You get COO-level expertise without the cost of a full-time hire, which in the UK typically starts at £80,000–£100,000+ per year.

Common Fractional COO responsibilities include:

Operational audits. Assessing what's working, what isn't, and where the gaps are across systems, processes, and tools.

Systems architecture. Designing the operational structure the business needs, what goes where, how tools connect, and what processes need to be built.

Hands-on implementation. Not just recommending, but building, setting up the systems, connecting the tools, and making sure everything actually works.

Strategic operational leadership. Owning the operational roadmap, identifying problems before they become crises, and thinking about the business between engagements as well as during them.

Team and process design. Defining how work should flow through the business, who owns what, and what needs to be documented.

When a Fractional COO is the right choice

A Fractional COO makes sense when the problem isn't a task or a project, but the operational foundation of the business. When you're the bottleneck not because you're bad at delegating, but because there's no structure for delegation to work within. When you've tried hiring help and it hasn't solved the problem. When you're growing and need someone to build the systems that will allow that growth to be sustainable.

It's also the right choice when you need someone who will actually implement, not just advise. A report that sits in a drawer isn't operations. A Fractional COO who builds it with you is.

When a Fractional COO isn't what you need yet

If you're at the very early stages of your business and your operational needs are simple and bounded, a Fractional COO may be more than you need right now. A good VA or a well-structured Simplify project might be the right starting point, building the foundation before bringing in strategic leadership.

How to figure out what you actually need

Rather than starting with job titles, start with the problem. Ask yourself:

Do I have specific, clearly defined tasks I need someone to take off my plate? If yes, a VA is likely the right first step.

Do I have a team or a launch that needs coordinating, and is the strategy already clear? If yes, an OBM might be what you need.

Am I the bottleneck in my business and is the problem the lack of structure, not the lack of people? If yes, a Fractional COO is probably the right conversation to have.

Have I hired help before and still felt like I was carrying everything? This is almost always a systems problem, not a people problem. Building the structure comes before any hire will stick.

One more question worth asking: do I need someone to tell me what to build, or do I need someone to build it? If the answer is both, make sure whoever you hire does both.

A note on platform-agnostic support

One thing I'd encourage you to look for, regardless of which type of support you hire, is someone who is genuinely platform-agnostic, meaning they'll recommend what's right for your business, not what they happen to know best or prefer to work in.

The best system is the one your team will actually use. And the best hire is the one who cares more about finding you the right answer than selling you a particular solution.

Every business is different, every team is different, and what works brilliantly for one founder might be completely wrong for another.

Not sure which one you need? Let's talk.

If you're trying to work out what kind of support would actually move the needle in your business, I'm happy to have that conversation, even if what you need isn't a Fractional COO.

I work with solo founders and small service businesses across the UK through a range of services, from focused project work to ongoing operational partnerships. The right starting point depends entirely on where you are and what you're trying to build.
