Tax season is when an accounting firm can least afford slow or unreliable internet. Cloud tax software, client portals, scanned documents and video meetings all peak at once, and client data must stay secure.

Remote and Hybrid Work
Many firms let staff work from home during tax season. Secure VPN access, multi-factor authentication and enough upload bandwidth at the office let remote staff reach files and software as if they were in the building, without exposing systems to the internet.
Phones and Client Communication
Clients call more during tax season. Hosted VoIP business phones with call routing, voicemail to email and mobile apps keep calls flowing, and they work on the same reliable connection with call quality prioritized.
Deadline-Proof Your Connection
Use dedicated fiber or fixed wireless internet in Detroit as the primary connection and backup internet so a cut cable never costs a filing deadline.
