To save a sale in SellTreez, simply click the Save Sale button on an order.
You can also click the Current Sale timer in the right-hand corner. This will open a drop-down of options, where you can choose Save Current Sale.
To view your saved sales, from the SellTreez window click the Current Sale tile > View Saved Sales.
NOTE: Saved Sales reserve the items in the order indefinitely and make them unavailable for other customers. For this reason, it's important to regularly clear Saved Sales to avoid inventory from being improperly held.
