Start here

In plain words: An auditor asks what you had in stock on 30 September, and why the count of a product moved. Odoo shows today's stock; to answer, you dig through moves. Stock Card & Inventory Valuation at a Date gives you two reports: the stock card (kardex) of a product, with its opening balance, every receipt, delivery, transfer and adjustment and a running balance; and the inventory valuation on any past date: quantity, average cost and value of each product.

The stock card of a product, the inventory valued on a past date, and the printed card.

Tip: Both reports open on screen, print in PDF and export to Excel.

The stock card

In plain words: Open Inventory → Reporting → Stock Card. Choose what, where and when, and press Show the stock card.

Choose the products or a category, the warehouse or locations, and the period.

Field	Meaning
Products	One or more storable products.
Product category	Instead of products: all the storable products of the category and its sub-categories.
Warehouse	All the internal locations of this warehouse.
Locations	Or choose locations (their sub-locations are included). With neither, the whole company.
Period	From and to, in your time zone. The opening balance is the stock at the start of the first day.

The card of a keyboard: opening balance, receipts, deliveries and an adjustment, with the balance after each.

In plain words: Each row shows the date, the reference of the transfer, the partner, the operation, where it came from and went to, what came in, what went out and the balance. The opening and closing balances are in bold.

What is on the card

Case	On the card?
Receipts, deliveries, adjustments, manufacturing	Yes: done moves in or out of the selected locations.
A transfer between two warehouses	For one warehouse: out of one, into the other, named Transfer. For the whole company: not shown, the stock did not change.
A move between two locations of the selected warehouse	No: the stock did not change.
Reserved or waiting moves	No: only moves that are done.
Products with no stock and no move in the period	Not listed.

Inventory valuation on a date

In plain words: Open Inventory → Reporting → Valuation at a Date, choose the date (and a category, if you wish) and press Show the valuation.

The stock of three products on 3 October, with the quantity, average cost and value of each.

Costing method	How the value is found
Standard price	The standard price at that date times the quantity at that date.
Average cost (AVCO)	Odoo's average cost computed up to that date.
FIFO	The layers still in stock: each receipt is a layer at its cost and each delivery uses the oldest layers first.

Tip: Tick Include products without stock to list the products that had none on that date.

Print and export

In plain words: Both screens have Print (PDF) and Export to Excel.

Who can use it

In plain words: Inventory users and managers. The reports are created and thrown away by Odoo; nothing is kept in your database after a while.

Arabic and right to left

Limits

Limit	Detail
No value on the stock card	The card is in quantities. The value is in the valuation report.
Valuation is company-wide	The valuation covers all the stock of the company, not one warehouse.
Moves are placed by their date	A move is counted on the date written on it (the validation date unless you changed it).
Lot-valued products	Valued by lot with Odoo's own figure for the date.
Size	Up to 1000 products at a time. Choose a smaller category for more.

For developers

In plain words: Skip this chapter if you only use the module.

Item	Details
Models	`taqnix.stock.card` (with `taqnix.stock.card.line`) and `taqnix.stock.value` (with `taqnix.stock.value.line`), all transient.
Methods	`action_compute`, `action_print`, `action_export`.

card = env['taqnix.stock.card'].create({
    'product_ids': [(6, 0, product.ids)], 'warehouse_id': warehouse.id,
    'date_from': '2026-01-01', 'date_to': '2026-09-30',
})
card.action_compute()
for line in card.line_ids:
    print(line.date, line.label, line.qty_in, line.qty_out, line.balance)

Troubleshooting

Problem	What to do
“There is no stock and no movement for these products”	Widen the period, or check the products are storable and the warehouse is the right one.
A move is missing	Only done moves count, and only those that go in or out of the selected locations.
The value of a product is zero	Check its category's costing method and that its receipts have a cost (purchase price, or the standard price).
The date looks one day off	Dates follow your user time zone (Preferences).
Too many products	Choose a category, or fewer products.
