Welcome to the QuickBooks Online Community family! I'm glad to hear you're using the Reconcile feature in the program, to ensure a match between your accounts and bank statements. I know how important it is to manage your reconciliations accurately, so there's no mistake. I'll be happy to assist you with this
Once you select the Reconcile feature and Start reconciling a specific account, QuickBooks Online displays every transaction from your chart of account that was never reconciled before. You have the flexibility to select any transaction you want as long as they match your bank statement period you're working on. It's always good to go through this process with your accountant to ensure everything is done properly, as making errors could put you out of balance the next time you try to reconcile. In case you don't have an accountant, you can find one on our Find-a-ProAdvisor website
