# E2 Inventory Pricing Updates
Below is an information-flow diagram of purchased-inventory price.
Notably:
* RFQs alone do not update an item's vendor price-breaks. (Can't do easy forecasts in quotes to customers.)
* Price breaks can only be updated by processing a PO.
* While recording an invoice users can optionally update the unit-cost on a PO. This update does not trigger re-processing of a PO. Invoices do not affect:
* price-breaks,
* stocking costs, or
* bin costs.
* POs spawned *without* RFQs will effectively pull the "last PO price break".
* While E2 supports recording that a part can be sourced from multiple vendors, E2 does not support vendor-specific price breaks or vendor specific SKUs.
* When two suppliers exist, extra care must be taken during the purchase process. RFQs —while time-consuming for all parties— are the safest process.

Out of scope of this diagram: There is a company-setting for how parts in bins get posted to a job. It defaults to using the average cost of the parts. Other options include using stocking, FIFO, or LIFO costs.
