TeamViewer "commercial use detected": what to do

TeamViewer shows "commercial use detected" because it is free for personal use only, and its system flagged your activity as professional. Free sessions then get cut short. Your three options: declare personal use if that is genuinely the case, buy a TeamViewer license, or switch to a paid tool built for technicians.

Why it happens

TeamViewer's free tier is for private, non-commercial use. Patterns that look professional — connecting to many different machines, helping other people, use during business hours — can trigger a "commercial use detected" (or "commercial use suspected") flag on your device or account.

What it changes

Once flagged, free connections are limited: sessions can disconnect after a short time, and repeated attempts may hit cooldowns or a temporary block. It is a nudge toward a paid license, not a bug to work around.

Your options

1. Declare personal use. If your use really is non-commercial, TeamViewer has a form to declare it and request a reset of the flag.

2. Buy a TeamViewer license. The correct path for genuine business use. Plans start around $24.90 USD/month (Remote Access), billed annually.

3. Switch to a tool built for technicians. If a full TeamViewer subscription is overkill for a few fixes a month, a pay-per-use tool costs less. Inuksuk charges $2.99 CAD for a 7-day license (3 PCs), with monthly ($5.99 CAD) and unlimited ($10.99 CAD) plans if you grow — and your end client pays nothing.

Frequently asked questions

Why does TeamViewer say "commercial use detected"?

TeamViewer is free for personal use only. Its system flags activity that looks professional — supporting other people's machines, many different devices, business hours — as suspected commercial use.

What happens when commercial use is detected?

Free sessions get limited: connections may time out after a short period and you can face cooldowns or be blocked from connecting until the flag is cleared or a license is purchased.

How do I remove the flag if my use really is personal?

TeamViewer provides a form to declare non-commercial use and request a reset. If your use is genuinely commercial, that is not a fix — you need a license.

Is there a cheaper option for a technician?

Yes. If you support clients professionally, you need a paid tool. Inuksuk is a pay-per-use alternative: $2.99 CAD for a 7-day license (3 PCs), with no yearly commitment.
