Yes! From September 2020, the Bluechain integration with Xero supports multiple cards in Bluechain mapped to multiple reconcilliation accounts in Xero.
To map your Bluechain cards to Xero accounts, first ensure that all of the cards you wish to use when paying bills from Xero have been added into the Bluechain app. This includes credit cards, debit cards, and bank accounts. Add any missing cards to the app by swiping the card carousel to the left until the "Add payment method" message appears.
Secondly you need to have a Xero account setup for each of the cards that you will use. Add any additional accounts to Xero by following the instructions at https://central.xero.com/s/article/Add-a-bank-account-or-credit-card-account-AU
Configure the mapping between Bluechain cards and Xero accounts through the integration setup pages at https://integration.bluechain.com/
Once you save your settings your payments will be reconciled into your chosen Xero accounts for future transactions.
