Hi there, @Tam22.
Currently, the only way to know if the estimate is accepted by your customer is to contact them. Once confirmed, you'll have to manually take note by adding it as a memo as my colleague stated above. You can refer to the screenshot provided by my colleague @Kristine Mae .
I understand this feature could play a big part in our customers business. I'll submit a feature request on your behalf to our product engineers so they'll consider adding it in the future.
Also, to learn some tips on managing your QuickBooks Desktop account. You can always visit our Help articles page for reference.
