Frequently Asked
Questions

Questions worth answering before you sign up.

What does a virtual administrative assistant do?

A virtual administrative assistant handles the operational and organisational tasks that keep a business running — inbox management, calendar scheduling, CRM updates, travel booking, document preparation, data entry, meeting coordination, and vendor communication. The key difference from a traditional admin assistant is that they work entirely remotely, typically on a flexible monthly plan, and are matched to your specific tools and working style.

What's the difference between administrative assistant services and a virtual assistant?

The terms are often used interchangeably, but in practice: traditional administrative assistant services refer to in-office or on-site support, typically full-time employees. Virtual assistant administrative services deliver the same support remotely, with more flexible pricing and faster onboarding. With Ossisto, you get a pre-vetted specialist — not a generalist — which means better results on the specific tasks you need handled.

Can my virtual administrative assistant work in my time zone?

Yes. During the matching process, we identify your required working hours and time zone, and match you with a VA who covers those hours. Ossisto serves clients across the US, UK, Australia, Singapore, Canada, and more — so we have VAs across time zones to suit your needs.
