Lot Reservation from Sales Orders

Reserve specific lot and serial numbers right on the quotation.
Lock them so no other order can take them, then ship exactly what you promised.

Auto-picked by your removal strategy, hard-locked across quotations, and pushed straight to the delivery on confirmation.

The lot problem every stock seller knows

Promising a lot at quotation time is guesswork in standard Odoo

The same lot sold twice

Two salespeople promise the same batch to two customers because nothing reserves a lot until the delivery is validated. Someone ends up disappointed.

The wrong batch goes out

Standard reservation happens at the warehouse, not on the order, so the customer who needs a specific expiry or batch has no way to lock it from the quotation.

No view of quote-held stock

Stock that open quotations are counting on is invisible. Planners cannot tell what is really free to sell until orders are confirmed.

What this module does

Lot Reservation from Sales Orders moves lot and serial selection onto the quotation. The moment you add a lot-tracked product, the module auto-selects available lots in the product category removal strategy, FIFO, FEFO or LIFO, splitting across several lots when one is not enough, and hard-locks them so no other open quotation can take the same lot.

A Manage popup shows each lot free-to-reserve quantity and blocks over-committing. On confirmation the exact lots flow to the delivery as Odoo standard reservation, and a Quote Reserved column on your product and inventory reports shows how much stock open quotations are holding.

🏷️
Auto-pick by strategy

Add a lot-tracked product and the right lots are selected for you in FIFO, FEFO or LIFO order, split across lots when one does not cover the line.

🔒
Hard-locked lots

Once a lot is reserved on a quotation no other draft or sent order can take it, so the same batch is never promised to two customers.

🚚
Straight to delivery

Confirm the order and the exact lots you reserved become the delivery reservation, so the warehouse picks precisely what was promised.

📏 Available column with guard

The Manage popup shows each lot free-to-reserve quantity and blocks any attempt to reserve more than is actually available.

✂ Automatic split across lots

When a single lot cannot cover the ordered quantity the module spreads the line across as many lots as needed, in strategy order.

♻ One-click release

Release a line reserved lots in one click to free them instantly for any other quotation that needs them.

📦 Quote Reserved column

Product and inventory reports gain a Quote Reserved figure for stock held by open quotations, separate from standard Reserved.

📊 Shortfall shown, never blocked

If stock is short the module reserves what is available and shows the shortfall, leaving the rest to Odoo native reservation.

📋 Reserved lots on the line

A compact summary column on each order line shows the reserved lots at a glance, with a Manage button to view or adjust them.

🔁 Auto-updates on edits

Change the product or the quantity on a line and the reserved lots are recalculated automatically against live availability.

🧩 Built on native stock

Reservation rides on Odoo own quant and move-line engine, so reports, traceability and delivery flows all stay consistent.

It follows your removal strategy

FIFO

First in, first out. The oldest received lots are reserved first. Used by default when no strategy is set.

FEFO

First expiry, first out. Lots closest to their expiry date are reserved first, ideal for perishable stock.

LIFO

Last in, first out. The most recently received lots are reserved first when that suits your operation.

How it works

1
Add a lot-tracked product

On any quotation, add a product tracked by lot or serial. The module immediately reserves available lots in your removal strategy order.

2
Review or adjust in the popup

Open Manage on the line to see each lot, its free-to-reserve Available quantity and the amount you are holding. Over-committing is blocked.

3
Lots stay locked to the order

No other open quotation can grab the same lots. Release them in one click if priorities change and they are freed instantly.

4
Confirm to push to delivery

On confirmation the reserved lots become the delivery reservation using Odoo standard stock engine, ready for the warehouse to pick.

5
Track quote-held stock

Watch the Quote Reserved column on products and inventory to see what open quotations are holding, freed automatically on cancel.

Frequently asked questions

How do I reserve a specific lot number on a sales order in Odoo?

Add a lot-tracked product to the quotation and the module auto-picks available lots in the product category removal strategy. Open the Manage popup on the line to see, adjust or release the reserved lots, which are held for that quotation until you release them or confirm the order.

Can I stop two quotations from reserving the same lot in Odoo?

Yes. Reserved lots are hard-locked. Once a lot is committed on one open quotation, no other draft or sent quotation can reserve the same lot until the first one releases it or is cancelled, so two customers never get promised the same lot.

How does the module decide which lots to pick?

It follows the removal strategy set on the product category, FIFO, FEFO or LIFO, and defaults to FIFO when none is set. It reads real on-hand availability and splits the quantity across several lots automatically when one lot does not cover the line.

What happens to the reserved lots when I confirm the order?

On confirmation the exact lots you reserved are pushed to the delivery order as Odoo standard reservation, so the warehouse picks the same lots that were promised on the quotation. There is nothing extra to do at the delivery step.

How can I see how much stock is reserved by quotations that are not yet confirmed?

A Quote Reserved column on the product and inventory reports shows the quantity held by open quotations. When a quotation is confirmed that amount moves into the standard Reserved figure, and when a quotation is cancelled the amount is freed automatically.
