Every order carries two statuses, because being paid and having sent the item are different facts and either can be true without the other.
Payment status
- Pending — recorded, not yet paid.
- Paid — the buyer has paid you.
- Failed — payment did not happen.
- Refunded — you have given the money back in full.
- Partially refunded — you have given part of it back.
- Cancelled — the order will not go ahead.
Fulfilment status
- Unfulfilled — nothing sent yet.
- Partially fulfilled — some of the order has gone.
- Fulfilled — packed and done.
- Shipped — handed to a courier.
- Delivered — it arrived.
- Returned — it came back.
Marking an order fulfilled, shipped or delivered takes the items off your stock count. Moving it back out of those states puts them back. Keep the statuses honest and your stock stays honest for free.
