Clean up Quickbooks

HI, I'm a small business start up. We have been using Quickbooks On-Line since start (Jan 2021) and I think we did a pretty good job at keeping track of expenses, linking accounts and setting up a chart of accounts. I currently have 1 bank account, two credit cards linked to the account. We have averaged 10-20 transactions per month and have no revenue as of now. I need someone who can take a look at our quickbooks set up and let me know if there are areas for improvement. I would require an NDA before I let someone into my quickbooks.
