What our customers say

“Comsource really understands our business needs. We had an urgent fault and they even managed to send a technician on a Saturday.”
Kelly Brimbore, Newcastle
“The Cloud PBX system that Comsource supplied when we moved to NBN has worked seamlessly and saved us some 30% a month on costs”
Alex, IT Manager, Brunswick
“We’ve dealt with the same guy for 4 years, they understand our day to day needs and are always very prompt in helping us out.”
Nikki, Practice Manager, Glen Iris
“I just like speaking to the same person every time I call - and consolidating our different phone, mobile and Internet into one account just made sense.”
Marti, Business Manager, Melbourne
“Moving to Comsource just made our lives easier, we deal with our account manager directly and our requests are dealt with the same day. Because of our location we can easily be impacted by weather events, they are always quick to help and provide practical workarounds when needed.”
Dr Wayne, Family Doctor, Hervey Bay
“We joined Comsource 5 years ago for service and price, then in 2018 we upgraded to a Cloud based PBX system, it was seamless and cheaper to run, wish that we had done this sooner, our clients spend less time waiting for help and our front desk now runs more smoothly.”
Dr Julie, Vet, Port Melbourne
