A wellness studio's four systems, one Salesforce org.
StripeSquarespaceAcuityGmail→Salesforce
Customers paid in Stripe, bought in Squarespace, booked in Acuity and asked for quotes by email. Many payments had no customer name, and the same people appeared in every system under different spellings.
Matched 45 customers recorded only as "unknown" to real people through store order records.
Merged people across all four systems and added 60 booking-only customers.
Added a visit summary to 648 contacts and named the buyer on every sale.
Follow-up dry runs found every record unchanged, so nothing was duplicated.
