Setup fee
Also known as: setup fee, onboarding fee, implementation fee, one-time fee
A setup fee is a one-time charge a vendor levies to onboard a new customer — configuration, number provisioning, training, or building a custom AI agent — separate from the recurring subscription. It changes the true first-year cost and can make a low monthly price more expensive than a rival with no setup fee.
The monthly price is the number buyers compare; the setup fee is the one they forget. It is a one-time charge for getting started — provisioning numbers, configuring the workflow, training the AI on a business's knowledge, or a guided implementation. On AI receptionist and texting platforms it can range from nothing to a few hundred dollars or more, and it lands before the service produces any value.
Why it matters: the setup fee distorts the real comparison, especially over a first year and especially for a short commitment. A vendor at a slightly higher monthly rate but no setup fee can be cheaper in year one than a lower-monthly rival that charges a large onboarding fee. The fee is also a switching cost — it raises the bar to trying a competitor later.
For a buyer, the setup questions are: is there a one-time fee at all, what does it cover, is it waived on annual plans, and what is the all-in first-year cost (setup plus twelve months) rather than just the headline monthly figure.
