How do I enable 'purchase order' as a payment method?
Go to Commerce > Payment methods, and tick Purchase order as a payment method.
What happens if someone pays by 'purchase order'?
During checkout they are required to fill in a Purchase order number.
Any orders that are paid by Purchase order are marked as Awaiting payment. Once you have received payment for an order (outside of Airsquare), you need to add a payment to that order, to mark it as Paid.
What happens if Xero is connected?
If the person pays Purchase order, and Xero is connected, an invoice is created but left unpaid. It's then up to you to chase payment.
If payment terms are set up in Xero, we use them to set the Due date of the invoices created.
Can the 'purchase order number' be used as the Xero invoice reference?
Yes. To enable this:
In Airsquare, go to Account > Connected apps.
Find Xero in the list and click Settings.
Under Invoice options, tick Use purchase order number for invoice reference.
