miBilling: Fixing a Duplicate Contact in Xero

Why this happens:

When miStable uploads an invoice to Xero, it first attempts to create a Contact in Xero. Here's how it works:

1. The system checks if a Xero contact already exists with the same email as the one in miStable.

2. If a matching email is found → it uses the existing Xero contact to map with miStable.

3. If no match is found → it creates a new Xero contact using the name and email from miStable.

Common Scenario:

Let's say there's a person named Ben.

• In Xero: Ben was already created with [e-mail]

• In miStable: Ben is listed with a different email: [e-mail]

→ When uploading an invoice, miStable doesn’t find a matching email in Xero, so it tries to create a new contact.

However, Xero doesn't allow duplicate contact names, so it creates the new one as Ben 1 instead of Ben. This results in a duplicate contact issue - now you have two Ben's with different emails.

How to fix the duplicate contact issue:

1. Update Email Address

• Check which contact has the incorrect or outdated email.

• Update the email address either in Xero or in miStable, depending on which one needs to be corrected.

2. Merge Duplicate Contacts in Xero

If a new contact like Ben 1 has already been created, you’ll need to merge following the instructions here.
