You’ll need to add the card you used. You should add any credit cards or bank statements that you use for business to your Crunch account. There’s no limit on how many you can add.
By recording the bank account or credit card that the payment was made from you’ll be able to select this when recording expenses or client payments. It’s also important to have the correct accounts listed in order to reconcile your transactions and ensure your Crunch account is in tip-top shape.
If you’re using a personal account/credit card, you’ll only need to record/reconcile transactions related to your business in Crunch. We have got a handy article in our help centre that explains more about reconciling personal accounts/cards
