Connect your accounts
Authorize each POS account. Every new connection starts import-only, with deletes ignored.
Connect distinct Square accounts. Connecting the same account twice does not create a second customer directory.
Customer sync pairing
Square to Square customer sync
Share customer details between distinct Square accounts. Review imported records and choose which account supplies updates before live sync.
What syncs
Keep shared customer details up to date.
Sync direction depends on your account settings. Choose which account supplies customer details and which accounts can receive changes.
- Initial customer import from each connected account.
- Customer creation and updates after you enable writes and go live.
- Shared first and last names, email addresses and phone numbers.
- Customer matching with uncertain identities left for review. Phone matching uses a country only when it is clear.
- Sync status, issues needing attention and customer change history.
- Pause controls when you need to stop sync.
Setup and controls

Review the import

Pairing limits
Know what your accounts can receive.
Deletes are your choice
Square can receive customer deletes. You choose whether deletes propagate in each account's settings. New connections ignore deletes by default.
Shared fields, with provider limits
Shared names, email addresses and phone numbers follow the receiving provider's requirements. Additional customer fields depend on each provider's read and write support. Supported provider-specific fields can be copied and overwrite destination values, including between accounts using the same provider. Review imported details and account settings before enabling writes.
