I have a client with 4 employees, but 12 DIDs through VI. His phone bill (including the slightly less than $36 for all of the DIDs) is about $37 a month. He’s a sub tenant off my account, so I pay all of the fees and taxes (his support fee pays for the rest of that). Even though I have to set up different PEER and USER accounts for them, I only needed to do it once.
Another example - a customer needed to set up a series of local numbers that auto-forwarded to other national phone numbers (to avoid Collect Call fees). These lines use inbound and outbound simultaneously. The bill for each of them is under $5 each.
I can repeat this story over and over again. Most of my clients are small businesses, and with the exception of the one that does outbound telemarketing, their phone bills are all in the “under $10” a month range.
There are people on here every few weeks complaining about Twilio. If you like them, terrific - use them. They were hard to work with when I needed their help, and none of the rest of my suppliers are. Their prices don’t make the headaches we see here worth the “savings”.
