Use an individual invoice when the debtor matters
If a customer is expected to pay later, Xero needs an identifiable contact, invoice date, due date and outstanding balance. A daily retail summary cannot provide useful aged-debtor information for that customer.
Invoice status should be deliberate
A business may want imported orders created as draft for review, submitted for approval or approved according to its controls. The ecommerce order status alone should not silently choose the Xero authorisation state.
Payment handling is a separate decision
A paid card order can be accompanied by a Xero payment when the rule allows it. A BACS or account-term order can remain unpaid until the bank receipt is confirmed.
Contact matching prevents duplicate customers
Billing company, name and email provide candidate identifiers for matching or creating the Xero contact. A consistent strategy is more important than copying whatever text happens to appear in one order.
