Dext automatically detects supplier names when you submit Costs receipts, invoices, or financial documents. But sometimes the supplier may:
Not yet exist in your Dext account
Have a slightly different name
Appear under both a trading name and a legal name
In these cases, you can easily create, merge, or manage aliases to keep your supplier list clean and consistent.
Create a new supplier
If the correct supplier isn’t listed, you can create it directly from the Item Details page.
To add a new supplier:
Open the Item Details page
Click the Supplier field and search for the supplier
If it doesn’t appear, click +Add "[supplier name]" to create it
If you're connected to accounting software:
New suppliers created in Dext will also be created in your accounting software when the document is published.
To get a warning before this happens:
Go to Business Settings > Connections
Click Manage next to your accounting software
Select Settings
Turn on the toggle for Warn me when creating a new supplier under the General section
Merge duplicate suppliers
If a supplier was incorrectly extracted or published, you can merge duplicates to clean up your list.
To merge two or more suppliers:
Go to Costs > Suppliers
Use search or click Supplier duplicates
Select the checkboxes for the suppliers you want to merge
Click Merge at the top of the page
Choose the correct supplier name to keep, and click Merge
Important: Merging suppliers cannot be undone. If you’re connected to accounting software, make sure you merge the suppliers in it as well.
Delete a supplier
You can delete suppliers that only exist in Dext.
To delete a supplier:
Go to Costs > Suppliers
Tick the checkbox next to the supplier name
Click Delete at the top of the page
If the supplier also exists in your accounting software, delete it there first - otherwise it will re-sync into Dext.
Important: Once deleted, the supplier’s name will be removed from associated items, leaving the Supplier field empty.
Use supplier aliases
Over time, you might see variations of the same supplier (like “Acme Ltd” vs “Acme Inc”). Use supplier aliases to group them under one correct supplier.
When a document matches an alias, Dext automatically assigns it to the main supplier.
Adding an alias
From the Item Details page
If we detect that the item’s supplier name is a potential alias of an existing supplier, we’ll prompt you to confirm it under the Supplier field.
If you click Yes, they are the same, you can add the supplier name as an alias, and we'll start assigning new documents from it to the main supplier.
From the Suppliers list
Go to Costs > Suppliers
Click on the supplier name
Scroll to the Aliases section
Enter the alias name and click Add
Removing an alias
To remove an alias, go to Costs > Suppliers > click on the supplier name > go to the Aliases section > click the red ❌ next to it.
When removing, you’ll have the option to turn the alias into a new supplier if needed.
Note: When you remove an alias, your processed items will remain under the original supplier name. If you create a new supplier from the alias, it won’t be assigned to past items, but Dext will assign it to new submissions.
