The number of sub-accounts you can create depends on your plan:
Essentials plan: Up to 5 sub-accounts (including your main currency account)
Plus plan: Up to 10 sub-accounts (including your main currency account)
Pro plan: Unlimited sub-accounts
Each sub-account can be created in one of the four supported currencies: CAD, USD, GBP, or EUR.
Example:
On the Essentials plan, you can create up to 4 sub-accounts across the 4 currencies (CAD, USD, GBP, EUR), resulting in up to 16 total sub-accounts, plus your 4 main currency accounts.
On the Plus plan, you can create up to 9 sub-accounts across the 4 currencies, resulting in up to 36 total sub-accounts, plus your 4 main currency accounts.
On the Pro plan, you can create unlimited sub-accounts in addition to your 4 main currency accounts.
