Move a personal plan in

Did you pay personally before the organization existed? Then do not cancel the personal plan by hand. The sandboxes that bill your personal account would stop with it. Move the plan instead. When you move:

Every sandbox billed to your personal account bills the organization from that moment.
Your personal plan ends the same day.
Boat refunds the unused share of the month to your card.
Credit packs that you bought stay on your personal account.

boat --org acme billing plan 20 --move-personal   # first org plan, move included once it is paid
boat --org acme org migrate                       # org already on a plan

curl -sS -X POST "$BOAT_API_BASE/billing/move-to-org" \
  -H "Authorization: Bearer $BOAT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"teamId": "team_..."}'

The dashboard offers the same move in two places:

The Billing tab of the organization.
The cancel-plan dialog of your personal plan.
