It is never recommended to delete an Ad hoc Supplier, as this can have a negative effect on your invoices, and deliveries.
Instead, we recommend using the Lightbulb feature to mark a Supplier as inactive. This allows you to keep past orders but will stop new ones being placed.
At the top, click the Admin Cogs
icon.Click Suppliers, Manage Suppliers.
Find and select the Adhoc Supplier.
Click the Magnifying Glass icon.
On the Suppliers tab, check the colour of the Lightbulb icon:
Yellow: The supplier is active.
No colour: The supplier is inactive.
To make a Supplier Active or Inactive, click the Lightbulb
icon. The colour will change.
You can keep your suppliers up to date in this way, and avoid orders being placed for suppliers you no longer use, but still keep your historic orders correct, and available to amend if required.
