Hi there,
I'm happy you're using QuickBooks to manage your books with ease. Don't worry, I'll be happy to share more info so you're on the right path.
Entering transactions is an essential step for making sure your books are accurate. If you're manually entering transactions you'd have to do that one at time. The good thing is QuickBooks offers a versatile Banking feature which allows you to connect your bank and automatically sync your transactions. I encourage you to check out this helpful article here: Connect bank and credit card accounts to QuickBooks Online.
Once you've connected your bank, you can set up Banking Rules. When you download transactions from your bank, you need to categorize them so they go in the right accounts. Bank rules speed up this review process. You can create rules that automatically categorize transactions for you. The more QuickBooks uses your bank rules, the better it gets at categorizing. After a while, it can even scan transactions and add details like payees. Check out this helpful article for more info: How to set and use banking rules for downloaded transactions.
I hope this info helps. In case you have other questions, feel free to contact our support team using this link here. Otherwise, feel free to leave a comment below. I'll be one message away.
