I’m experiencing critical issues with QuickBooks Premier 2025. The software freezes frequently during payroll processing, and multi-user mode isn’t working properly—often throwing error codes like H202, H505, or PS077.

I'm trying to find a reliable, certified support channel that can help troubleshoot these specific issues. I've already attempted basic fixes like reinstalling QuickBooks, reconfiguring firewall settings, and checking hosting services—but no luck.

What I Need Help With:

Is there a legit support phone number I can call for QuickBooks Premier desktop issues in 2025?

I came across Biziblaze at https://biziblaze.com/ and their support line +1-888-375-8021 — has anyone here used them for QB Premier payroll or multi-user errors?

Are there any trusted support resources that handle Windows 11 compatibility for QB Premier?

Current Setup:

QuickBooks Premier Desktop 2025

Windows 11 Pro

Multi-user (3 users via shared network)

Payroll Subscription Active

Any guidance, suggestions, or experiences would be greatly appreciated. Just want to get back up and running smoothly.
