I have a number of duplicated suppliers e.g. Adler v Adler Ltd- is it possible to merge the invoices and payments into one supplier account?

Thanks for joining us here on the Community, mrrostron

You can edit the duplicate supplier 'Display name as' fields to be the exact same as the target supplier account and a message will appear when saving this 'That name is already being used. Would you like to merge the two?' with the option to confirm or deny. 

To edit the supplier details, simply go to Expenses > Suppliers > Click onto duplicate supplier listed > Edit > 'Display name as'. 🙂
