Your supplier list comes from your integrated accounting software and from items that you have submitted (as each item must have a supplier).
If a supplier has come through from your accounting system you can delete it there and this change will flow through to Receipt Bank.
If there are two supplier entries that are the same (e.g. Apple and Apple Ltd) you can merge them:
1. Click on the 'Suppliers' tab.
2. Select suppliers you wish to merge using the check box.
3. Click the Merge icon at the top.
4. Select the Supplier name you wish to take precedence, then click Merge.
