Hi,
I built QuoteWise on my own and I still run the support inbox myself. So if something breaks because of the plugin, or you just can't figure out a setting, I'm the person who's going to write back. Not a chatbot. Not a support rep working off a script.
You'll usually hear from me within 12 hours, with the actual code or steps you need to paste in. If I can't sort out what's wrong inside 48 hours of you writing in, your money comes back. A full refund, within 14 days of the purchase. No forms.
The honest reason I can offer this is that the team is one person right now. I read every email myself, so the bar is whatever I'd want from a plugin I'd paid for.
