Backflush accounting

Backflush accounting is a product costing approach, used in a Just-In-Time (JIT) operating environment, in which costing is delayed until goods are finished. Standard costs are then flushed backward through the system to assign costs to products. The result is that detailed tracking of costs is eliminated. Journal entries to inventory accounts may be delayed until the time of product completion or even the time of sale, and standard costs are used to assign costs to units when journal entries are made, that is, to flush costs backward to the points at which inventories remain.

It can be argued that backflush accounting simplifies costing since it ignores both labour variances and work-in-progress. Backflush accounting is employed where the overall cycle time is relatively short and inventory levels are low.
