I’m not sure what you mean by “created another linking to my bank account”?
If you have multiple bank accounts, they won’t affect your accounts in terms of Profit & Loss - these go by invoice value. What it would affect however is your balance sheet, for example if they show more money in the business than what is actually there.
To delete an account, you can delete any transactions in it, and then it should allow you to delete it. However, if you have tagged transactions, to invoices for example, then the invoices will become unpaid.
Thanks for your response, I meant that I’d created a duplicate bank account and tagged some invoices in one and some invoices in the other. i’ve now managed to delete the duplicate account, thanks for your help. However, now my balance is incorrect in the existing account. I’m unsure if this is the reason why? All of the invoices are tagged correctly.
