The Portable Office Company

The Portable Office Company (POC) is the channel solution for white labelled Virtual Desktop distribution. We have launched the first truly channel focused, cloud based Windows® desktop to market. 

As traditional voice revenues for telecoms operators continue to fall, the POC Virtual Desktop™ offers unparalleled returns on a per seat basis with an average revenue per user of £49 – compare that to on average Fixed Voice at £22.26, Fixed Broadband at £13.70, Mobile Voice at £13.34 and Mobile Data at £2.09* - adding our solution to your portfolio makes great business sense. 

Distributing via select partners in the telecommunications industry, we have designed a user interface that automates virtually every aspect of setting up a small business IT infrastructure, simplifying management, and vastly reducing costs for both the end user and the distributor. 

If you are a telecoms operator interested in this new innovative solution please call 0871 716 7945 or email me ross@pocster.com to find out more information or to arrange a demo.
