We can perform some steps  to fix your QuickBooks from crashing when recording a sales receipt within your company file.

First, download the latest product updates to ensure you have the  recent update of QuickBooks.

2. If a newer version is available, click Install Update.
3. When prompted, click Install and Relaunch.
4. When the update is complete, QuickBooks for Mac automatically opens.

Once done, we can run the Verify and Rebuild Data within your company file to fix issues.

1. Select File, then select Utilities.
2. Select Verify Data, then select OK to close all windows.

Then, proceed with the steps outlined in the How to rebuild your company file data section. Check this article: Find the most common data issues in a company file and fixes them.

If the same thing happens, we can upgrade your QuickBooks to latest version to make you have the latest features and fixes.
