They did, just abrupt and no training or explanation, probably because they expected you to get ALL the info off that statement. God, reminds me of ,y current professor or me...
This sounds like a voided transaction, which means a) it was a no sale, b)restock, or c) exchange. What they didn't say is this: check date to see if 2020 or prior first and then inventory.
If the invoice was before 30 Sept 2020, maybe 2021, you can usually be ok to replace, but an invoice is a record, so check retention. If it happened after, you need both. You can be audited for the last 1000 or so transactions, and let's say 20 are voids or returns so you delete 5 invoices. Now, you have 980 transactions and no records for 5 and 15 zeroed but traceable events. so they have to be replicated or more likely, an inventory will be done.
After the end of the next fiscal year, it won't matter as much because all items and money for the fiscal year 2 years ago is accounted for. 2020 is probably ok, 2021 or 2022 is not.
Maybe, I don't know. This is just how I handle ,y business funds and inventories.
