How do you handle no-shows as a solo service provider?

I keep hearing the same thing from trainers, coaches, and photographers: a client no-shows or cancels last-minute, and there's nothing they can do. That hour's just gone.

Most booking tools stop at a reminder. Some let you take a deposit, but it's clunky and optional, so people skip it.

I'm building Sessurely around the opposite idea: keep a card on file and automatically charge the no-show/late-cancel fee, so the cost lands on the person who flaked instead of the pro. Building it solo, still early.

Curious how people here actually deal with this today:

• Do you charge for no-shows, or just eat the cost?

• If you take deposits, what's stopped you (awkward to ask? tooling?)

• What would make you trust an automatic charge vs. doing it manually?

Genuinely want to learn how others approach it; not just pitch mine.
