When deleting or recreating entries when discrepancies occur in customizing forms in QBO helps ensure financial data accuracy and compliance, preventing potential errors from impacting financial reporting.

Moreover, to address the issue of missing columns when printing or downloading, please ensure to select the specific template you customized under the Custom Form Style tab. You can then proceed to create or edit the transaction to display the customized template you selected. Here’s how to do it:

1. Navigate to the Sales tab, and select either Invoice or Estimate.
2. Pick the specific entry you wish to modify.
3. Click on View/Edit.
4. Under the Design tab, use the dropdown button to select your desired template.
5. Click Save once you've made your changes.
