Fin handles the bread-and-butter support stuff really well, FAQ-type questions, order status, basic troubleshooting, without needing much hand-holding once the knowledge base is set up properly. The resolution rate we saw in the first month was better than expected, and the handoff to a human agent when Fin can't handle something felt smooth.

The integration setup to make that work isn't super plug-and-play, and you'll need someone reasonably technical to configure it right.
Pricing scales with usage so it can get expensive fast once volume picks up. Worth it if you're drowning in tier-1 tickets, but probably harder to justify for smaller teams where a human can genuinely keep up.
