Oh my goodness what poor answers from Intuit. If there is no "feature" to accomplish the task then there must be a "procedure" to do it as this is something that must accounted for. Here's what I suggest, using the example of receiving $400 in cash but only wanting to deposit $300 in the bank. Record two cash payments on the same date, one for $300 and the other for $100. Log the $300 to the bank and the $100 to the Undeposited Funds account. This will allow you to reconcile your bank statements with QBO and show you kept $100 in undeposited cash.
