GST 5% and PST 7%, kept apart
British Columbia runs two parallel taxes: GST administered by the Canada Revenue Agency (CRA), and PST administered by the BC Ministry of Finance. They are registered and filed separately, so they need to stay separate in your books.
HelloBooks applies both taxes per invoice line and posts each to its own liability account. The GST/HST return figures and the PST figures come from those separate balances. HelloBooks prepares the figures; you file each return with its authority.
