<aside> 🔗 This help guide assumes you already have your Xero account connected to Sellar via our integration.

So Sellar can successfully identify your customers in Xero when creating invoices via our integration, we need to know the Xero ‘Contact ID’.

You can find this by going to a specific contact in Xero and looking at your browser’s address bar. The long string of characters and numbers after /Contacts/View/ is your customer’s Contact ID. Copy and paste this into Sellar.

<https://go.xero.com/Contacts/View/ed08db9b-c943-4c87-a830-105cf4d8ab69>

In Sellar, go the customer’s page and select ‘Map Customer’. If you already have the Xero integration connected, you’ll be prompted with a single field to enter the Xero ‘Contact ID’. Add this here. From here onwards, we’ll link your customer as they are defined in Xero to the invoice when we create it upon confirming orders in Sellar.

<aside> ☝ Note: If you have previously entered the ID of your customer into the ‘Customer code’ field on Sellar, we will still check for a value here and use this should the dedicated Xero ‘Contact ID’ field be empty. The way Sellar attempts to identify your customer upon order confirmation is:

• Check the Xero ‘Contact ID’ field for a usable ID value
• If empty, check the ‘Customer code’ field for a usable ID value
• If also empty, pass along the raw customer details to Xero (name, delivery address, etc.)

Should no ID value exist on Sellar, Xero will use the raw customer details to create a ‘Contact’.
