Why seashellOS

Four things Bonsai charges extra for — or lacks.

No 1% payment markup

Bonsai adds 1% on top of card processing on every transaction. seashellOS adds nothing — your processor’s standard rate is all you pay.

$0 vs +1% per transaction

Flat pricing, not per-user

Bonsai bills per user, so a three-person studio pays three subscriptions. seashellOS Pro+ is one flat $19/month.

Client messaging built in

Bonsai has no client messaging. seashellOS gives every client a branded portal with a real message thread, file sharing, and payment history.

Shello AI, included

Bonsai has no AI assistant. Shello drafts messages, plans projects, and understands your business — included on Pro+.
