Office Cloud PBX and Managed IT

For 50 to 200-user offices outgrowing ad-hoc IT, SIPPER delivers Cloud PBX, IP phones, managed firewall, full WiFi coverage, PoE switches, file server or AD, and ongoing IT helpdesk. One vendor, one contract.

OFFICE IT 50 TO 200 USERS

Single-vendor IT with Managed Service

Growing businesses often accumulate IT from many vendors with no single accountable team. SIPPER consolidates everything: voice, network, security, and server into a centralized managed service with predictable monthly cost.

Call one number for all IT issues, whether VoIP, network, server, laptop, or printer.

Office IT Overview

Single-vendor advantage for growing SMB

SIPPER consolidates voice, network, security, and server into one managed service.

Why 01 / Scale

50 to 200 Users

SIPPER Office IT is designed for organizations beyond startup but not yet enterprise. At this size, you need proper infrastructure but cannot yet justify a large in-house IT team.

Why 02 / Predictable Cost

Predictable monthly cost

Hardware and installation are one-time investment. Managed Service, Cloud PBX, and call packages billed monthly at a fixed rate. No surprise repair costs. Proactive monitoring catches issues before they become outages.

Why 03 / Bundle

Pre-configured Bundle Packages

SIPPER pre-configured bundles combine voice, network, and security in 3 tiers: SME Starter, Business Growth, and Enterprise. Fully customizable.
