Can I memorize a transaction that recurs every month?

Hi there,

Welcome to the QuickBooks Community. I'll be glad to share more info and help make sure you're on the right track with your goals. 

Based on what you've shared above, I recommend taking advantage of the Recurring Transactions function. Here's a helpful article that provides more info about how to:  

Create recurring transactions in QuickBooks Online.  The article does a great job at showing you how to use and enter a recurring entry in QuickBooks at a monthly schedule as you've described. I encourage you to check it out and let me know if you need anything else as you go through the article. 

Feel free to ask other questions, I've got your back.
