If the same email address has been used by more than one customer to set up an account in your point-of-sale, you'll need to change this to ensure each customer has their own email.
Collect uses the email address of a customer as a unique identifier, therefore there will never be more than one account in Collect with the same email. All purchase information from any accounts with the same email in your point-of-sale system will track into one Collect account.
HOW DOES THIS HAPPEN?
There are a couple of reasons duplicate accounts will appear in your point-of-sale and not in Collect.
1. Two customers use the same email address.
This can happen if customers share an email address (e.g. husband and wife) and they both set up accounts in your point-of-sale.
2. One customer sets up multiple accounts.
This can happen if a new account is created for a customer instead of adding an existing customer account to a sale.
HOW DO I SEPARATE THE ACCOUNTS?
To separate the duplicate accounts going forward, simply change the email address of one of the customers in your point-of-sale. This will sync with Collect creating a customer account for the new email address.
Please Note: We cannot retroactively adjust points balances in Collect Loyalty. Points will automatically be applied to the customer account with the email address used at the time of sale. For instructions on how to manually adjust customers' points please see this article.
