Customers | Managing Duplicates
Spot and tidy duplicate customer records so spend history and marketing consent stay attached to one real person.
Duplicates happen: a customer checks out as a guest twice, an import runs twice, someone mistypes their own email. Two records for one person splits their history and muddies your marketing consent records.
Finding them
Search the Customers list by name and by email fragment — duplicates cluster around the same person with small variations (gmail vs googlemail, a typo'd address, a work email they later abandoned).
Tidying them
Decide which record survives — normally the one with the storefront account or the richest order history.
Re-point anything that belongs to the duplicate (open quotes, CRM deals, company contacts) to the survivor.
Delete the duplicate from the Customers list. Order history in your financial records is unaffected.
Preventing the next one
On imports, dedupe your CSV by email first — the import maps by row, so the same email twice creates two records.
Encourage account checkout for repeat customers; guests typing their email differently each time is the main duplicate factory.
Tips
Before deleting, check for an active subscription or gift-card balance on the duplicate — move or resolve those first.
