# Inventory, sales and COD

Part of the doc set: [ERP Tân Doanh](https://phatdev.net/en/docs/erp-tan-doanh.md)

> The lifecycle from goods receipt to delivery, COD reconciliation and returns.

## Inventory
- Receipt, issue and transfer slips; stocktakes that lock the warehouse while counting; opening-balance slips for the first cut-over.
- Barcode scanning with a handheld scanner, a camera (including on iPhone) or manual entry, with duplicate-read protection.
- Rolling weighted-average cost per item and per warehouse.

## Sales
1. **Quotes** are created quickly, change status, and convert into orders.
2. **Orders**: reserve stock, issue goods, hand over to the carrier.
3. **Successful delivery**: the point where revenue is recognised.
4. **COD reconciliation**: amount the carrier still owes = collected on behalf - remitted - approval fee.
5. **Returns**: refunded at the post-discount price, with cost taken from the exact issue it came from.

## Purchasing
Supplier purchase orders, reorder suggestions based on stock, and receiving against an order: when a receipt is approved or reversed, the order updates itself.

## Reports
The report centre lists every report together with the question it answers and hides reports automatically according to the user's permissions; the period picker has 8 time ranges.
