Hello acharya,
It's great to hear that you're using the bank feed feature with your QuickBooks Desktop company file. It can definitely help with cutting down on your workload by allowing you to easily add transactions or match them to existing ones in the program.
There have been reports of the issue you're reporting where the cheque numbers aren't showing up in the bank feed and making it impossible to match them. For that reason, I'd like you to call to our support team to have an agent look at this with you and see about attaching your account to our list of affected users.
