Good day

We have a prospect that want to do daily periodic stock valuations:

• Opening stock + receipts for day 1 = average value for day 1, and all sales for the day cost of sales will be adjusted by this cost
• Opening stock for day 2 + receipts for day 2 = average value for day 2, and all sales for day 1 and 2 cost of sales will be adjusted by this cost
• Etc etc

When stock is IBT to other sites, these must also be affected accross sites.

Is this something that was ever done by someone before?
