Question 1

How does Shopify store customer data?

Accepted Answer

Shopify creates a customer profile for each unique email or phone. Guest checkouts, multi-device usage, and typos cause fragmentation.

Question 2

Does MergeGuard use Shopify-approved APIs?

Accepted Answer

Yes. We exclusively use Shopify's official Admin API and follow all Shopify app development best practices.

Question 3

Will this affect my existing apps or integrations?

Accepted Answer

No. Customer merges update the canonical Shopify customer record. Other apps that reference customer IDs will see the merged profile.

Question 4

Does it work with Klaviyo / CRM tools?

Accepted Answer

Yes. Once customers are merged in Shopify, synced tools like Klaviyo will reflect the consolidated profiles on their next sync.

Question 5

Can it handle large Shopify stores?

Accepted Answer

Yes. MergeGuard is optimized for stores with 100,000+ customers. We process in batches to avoid rate limits.

Question 6

Does it work with Shopify Plus?

Accepted Answer

Yes. MergeGuard works with all Shopify plans including Shopify Plus.

Question 7

Are there API limits or performance impacts?

Accepted Answer

MergeGuard respects Shopify's API rate limits. Scans and merges run in the background with no impact on your store's performance.
