Split profiles hide your VIPs: a worked example

A VIP rule asks whether a customer has spent enough. It asks that of a profile, and a customer can hold more than one. This page shows how the split hides people, with the arithmetic, and what to do about it before you merge anyone.

How spend splits

Shopify’s Admin API describes a customer’s amountSpent as “The total amount that the customer has spent on orders in their lifetime.” That total belongs to one profile. A shopper who buys under a work email one month and a home email the next has two profiles, and each holds only the spend made under it.

The causes are ordinary: a second email, a phone number one time and an email the next, or a typo. Guest checkout and duplicate customers lists them.

The arithmetic

Here is an invented example.

Each profile falls short of the threshold. Together they clear it. A report of VIPs by profile misses her, and she gets none of the perks you meant for her.

MergeGuard’s demo store shows the same effect at store scale: 18 VIPs on single profiles → 27 VIPs as people Demo store (Northsail Supply). The extra VIPs were there all along, split across profiles.

Profiles Shopify won’t merge

Some of these customers can’t be merged, whatever you decide. Shopify’s Help Center lists cases where “Profiles can’t be merged”, for example when either profile “has, or has ever had, a subscription contract” or “has a store credit account” (Limitations for merging customer profiles). The full list of nine cases is on why Shopify blocks some merges.

Those customers can include your best ones, such as long-standing subscribers. A VIP count that relies on merging would miss them. Counting their spend together, without a merge, includes them. Read more on protected profiles.

Count first, merge second

Counting people for a VIP list is a reporting step. It reads your orders and adds spend across profiles that clearly belong to one person. It changes nothing in Shopify.

Merging is a different step, with its own rules. Shopify’s Help Center says: “After the profiles are merged, you can’t reverse the process.” If any profile in a merged pair is subscribed to marketing, the merged profile is subscribed. Count first, and merge only the groups you have checked.

Group profiles on the strongest signals first, such as a shared phone number, or emails that differ by a typo. A shared address alone is a reason to look, since people who live together share addresses. Keep those apart unless you have checked.

Check the new list

After you add up spend per person, compare the new VIP list with the old one. Look at the customers who joined. Each one should have a clear story: two or three profiles with a shared phone or a near-identical email. A customer who joined on a weak link, such as a shared address, deserves a second look before they get VIP treatment.

Then re-run the count after any big import or sale, because new duplicates form as new orders arrive. How to set a VIP threshold covers the review routine.
