When paying for any VoIP solution, you will have to cover one-time costs. These costs generally revolve around the setting up of new hardware on your commercial property. While you will only pay for these costs once, you must pay attention to them, especially if you are a smaller business without many financial resources. That said, there are a few one-time costs to look for: hardware costs, porting costs, and setup costs.
Hardware costs refer to the devices you need to facilitate VoIP calls. These can include headsets, phones, and the like. However, if you already have these tools or if the VoIP provider has an app, you may end up paying little to nothing.
Porting costs relate to transferring phone numbers into your new system. Some companies will do this for free, while others will require a fee. Ask your provider to clarify their pricing policy for such.
Finally, setup costs are costs that you incur from first switching to VoIP. Some vendors may charge you for this, while others may roll the cost into other expenses.
