Hello there, @shfd307zwh.
In QuickBooks Online (QBO), the Account Receivable (A/R) and bank statement will normally not match. There are times that the A/R gets credits or adjustments that do not appear in your bank.
I've added this link about the A/R balance does not match on the reports: AR balance on the Chart of Accounts does not match AR balance on reports.
Also, I encourage checking our Help articles page to learn some tips and tricks in managing your QBO account. From there, you can read great articles that can guide you through the steps by steps process.
Stay in touch with us if you have other questions. I'm always happy to help. Take care!
