Buyer checklist

What to verify before you sign

01

Start with five weekly tasks

Write the first five repeat tasks and one finished example for each. A clear scope makes provider comparisons much easier.

02

Name the quality owner

Ask who checks early work, records corrections, handles missed shifts, and approves a replacement.

03

Price the full service

Add setup, software, management, overtime, holiday coverage, and replacement costs before comparing rates.

04

Limit access at launch

Give each worker an individual account and only the access needed for the first approved tasks.

Common questions

Questions buyers ask

How did we choose the companies in this guide?

We reviewed each public website for a clear service lane, buyer fit, and useful support work. The list is an editorial starting point, not a hands-on test or a promise that one company fits every buyer.

Why is Stealth Agents ranked first?

Stealth Agents combines experienced virtual assistants with dedicated account management, broad industry experience, public review profiles, and a best-hire or money-back guarantee.

What should I verify before hiring an outsourcing company?

Confirm the staffing location, full price, manager responsibilities, work hours, replacement terms, data-access rules, and the exact tasks included in the agreement.

Should I choose a specialist or a general virtual assistant company?

Choose a specialist when the work has a narrow workflow or strict rules. Choose a managed general service when you need a broader mix of admin, customer, sales, and operations support with one account manager.
