For example, even if it shows a boost of $100,000 per month in revenue. It could likely have been achieved with a shared virtual assistant / receptionist for about $200-1000 per month (depending on exactly call volumes).
So really, the revenue was already lost and going forward you’re just deciding to capture it. You've created a more complicated mouse trap than what was already available to you. The difference is saving a couple hundred dollars of labor less whatever your AI/tech costs are. I’d still go the human route because it’s more future proof and if this is a luxury service, human service is always going to feel more luxurious.
