Thank you for reaching out, Denny! I understand the need to efficiently tidy up your accounts by declining multiple estimates at once.
Currently, QuickBooks Online doesn't have a built-in feature to batch decline estimates. You would need to decline each one individually, as you've noted.
However, to help manage this task more smoothly, you may consider using a third-party app from the QuickBooks App Store that offers batch management features or can assist with bulk updates.
Alternatively, if the volume is significant, exporting the list to Excel for record-keeping might be helpful, then manually marking them as declined in QBO.
If there's anything else I can assist you with or if you'd like to explore app options together, please let me know!
