What it does
When enabled, auto-post will skip settlements that contain products still sitting in your Default (catch-all) product group. This gives you time to assign those products to the correct group before they post to Xero or QuickBooks.
How to use
Go to Inventory → Product Groups
Find your Default product group (marked with 'Default' in brackets)
Click the dropdown menu (three dots) on that group
Select 'Enable Hold on Catch-All'
Confirm in the popup dialog
What happens next
Any settlement with unrecognised products in the Default group will be skipped during auto-post
Once you move those products into the correct group, the settlement will post on the next auto-post run
To turn it off, open the same dropdown and select 'Disable Hold on Catch-All'
Important Notes
This option only appears on the Default (catch-all) product group
If you change which group is the Default, the hold setting is automatically cleared from the old group
Settlements where all products are already assigned to named groups will continue to post normally
