Here goes:
15 Sets. @. 30. =. 450. 25%. Commission. =. $112
Circuit. $200. 15%. Commission =. $. 30
Total monthly recurring commission. =. $142.
1 month SPIFF. $450
Plus. Install $300
This is a average. The more phones the more MRR. Less phones less MRR
Keep in mind, if you don't sell your customers , in most cases someone else will.
Also the more you sell the more MRR you will receive. And also SPIFF can be much larger based on the number of sets .
So for 15 sets there monthly cost is $650 ...... forever.
We have a Magix in our office that is 20 years old. Our owner likes the idea of hosted. When I did the numbers for him and he realizes that over the 20 years we had it he broke even the first five while paying the lease he has then saved $350 per month or about $60,000 he changed his tune!
