Merge duplicate customers

Join two records for the same customer into one.

What this is for

Duplicates split a customer's trading history and quietly defeat credit control — a hold on one record does nothing about the other. Merging moves everything onto the record you keep, and old links still work.

Step by step

  1. 1

    On the Customers list, open the Possible duplicates banner.

  2. 2

    Check each pair and choose which record to keep.

  3. 3

    Read the counts of what will move, choose which details survive where they differ, then type the surviving customer's name to confirm.

Tips & gotchas

  • →Check the counts before confirming. "47 quotes" against a record you thought was empty means you've got the wrong pair.
  • →If either record is on hold, the merged record stays on hold.
  • →Merging can't be undone. Old links to the merged record redirect to the one you kept.
