Managing Accounts

You can add Company Accounts in the CRM to Xero as Customers and update Xero Customers that are already linked from the Company Account page.

The first time you go into a Company Account after connecting to Xero the system will check to see if the Account exists as a contact in Xero. If it does, it will update Really Simple Systems with a unique Account or Ledger Code. You will also be able to view the last invoice date and the total sales for the Company Account as well as any payments that are overdue. If you want to view the Company Account information on Xero press the blue “View on Xero” button on the Account page. If you make any changes to the Company Account you can update the information on Xero by pressing the blue “Update to Xero” button on the Account page.

If the Ledger Code on the Company Account is blank or does not exist in Xero, then an “Export to Xero” button will appear on the Account page. Press the button to sync the Company Account over to Xero and select the main contact for the Company Account from the dropdown option.

Export Account to CRM

If the Ledger Code is blank then Xero will create a default Customer Code and the Company Account will be updated with that Code. If the Ledger Code has a value then that value will be used for the Xero Customer Code.

When you add or update a Customer the Customer History in Xero will show the time, date and detail of the change.
