Optionally allow chosen people to pay On account.

Go to Commerce > Payment methods, and tick On account as a payment method. 

Then you can allow 'on account' payments for specific people or organisations, see below.

Go to Contacts > People, find the person, click Edit, then tick Allow person to pay on account and click Update to save. 

When this person logs in, they will then see On account as a payment method. They will have to have a Username and Password set up in order for them to login. 

Go to Contacts > Organisation, find the organisation, click Edit, then tick Allow organisation to pay on account and click Update to save.

When this a person logs in from this organisation, and is purchasing on behalf of this organisation, they will then see On account as a payment method.

Any orders that are created On account 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.

If the someone pays On account, 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.

During checkout we automatically show a field for Purchase order number if they have chosen On account as their payment method. It's not required to be filled in though.

Yes. To enable this:

If no Purchase order number is provided, then we use the Airsquare order number as the Xero invoice reference.

Not currently, but do let us know if you need this.
