Ship with the guides, not guesswork.
Every licence includes two setup guides. They are written for operators who have already been through a processor freeze and need the details to be right the first time.

- 2Install both plugins and run a test checkout using the setup guide.
- 3Go live on Site A once totals reconcile and emails send from both stores.

Payment store playbook
Build the payment store from an empty WordPress install: catalogue, policy pages, theme, and the state it needs to be in before you apply to a processor.
