Supplier Merge in DPO
The Supplier Merge feature lets you combine duplicate or obsolete suppliers into a single Target Supplier, helping keep your supplier data clean and consistent. To avoid accidental changes, the merge requires user confirmation before it’s completed.
What happens during a Supplier Merge
- All related documents are automatically updated to use the Target Supplier
- No manual amendments are required
- Duplicate suppliers are removed
- All changes are tracked in the Activity Log
Before you Start
The Supplier Merge feature is available by default to users with the Default Admin role.
If a user is assigned only the User role, you must create and assign an additional Supplier Merge role. Once assigned, the Supplier Merge tab will appear in the menu (see below for setup instructions).
In the Supplier Merge view:
- The Source Supplier appears on the left
- The Target Supplier appears on the right
How to Merge Suppliers
- Choose the Source Supplier and Traget Supplier
- Once both suppliers selected, click 'Preview Merge'.

- Confirm the merge by clicking "Yes, merge Suppliers"

Effects of the Merge
After confirmation, the system automatically replaces the source supplier with the target supplier in all relevant documents:
- P.O.s
- Invoices
- Expenses
In addition, a note is automatically added to each affected document indicating that a supplier merge has been performed.

Activity Log
- The Activity Log shows how many records were affected by the supplier merge.
- A note is also added to each affected document to indicate that a supplier merge was performed.

Create a Supplier Merge Role
- Go to Settings → User Roles
