Reservations#
Goods promised to orders that have not shipped. Reservations are why the e-shop says "sold out" while the goods sit on the shelf.
Find them under Sklad → Rezervace.
How they appear and disappear#
| Moment | What happens |
|---|---|
| An order is created | the goods are reserved |
| The order is sent | the reservation becomes a write-off |
| The order is cancelled | the reservation is released |
| The reservation expires | it is released by itself |
The physical quantity does not change with a reservation — only available does.
Reservations expire#
An unpaid order must not hold goods forever. A reservation therefore carries an expiry date; after it, the goods are released.
The reservation validity must be LONGER than or equal to the payment window
If a reservation is released before the order dies, the same goods can be sold twice — and a customer paying on day two has nothing to be filled from. The opposite mismatch is merely inefficiency: goods blocked longer than necessary.
Mind the units — they are not the same
The reservation validity is entered in minutes (warehouse settings), the payment window in hours (e-shop settings). Convert before comparing: three days is 72 hours, that is 4,320 minutes.
Releasing runs every 5 minutes
A reservation therefore outlives its validity for a while. Do not set values that need to be accurate to the minute.
When the numbers do not add up#
The warehouse's most common trouble: goods are in stock but cannot be sold.
In order:
- How much is reserved? The item shows three numbers — in stock, reserved, available.
- Are there orders behind them? A reservation with no live order is a leftover.
- Have they expired? A reservation past its date should release itself.
- Did they get stuck on a cancellation? An order cancelled other than by switching to a status with "Cancel the order" may not release its reservation.
The reserved quantity is a stored number, not a calculation
The system keeps it recorded rather than recomputing it from orders each time. If something fails mid-operation, a reservation can outlive its order. You recognise it because the physical figure is right and the available one is not.
Releasing a reservation by hand#
When a reservation is left with no order behind it:
- Confirm the order really does not exist or is cancelled.
- Cancel the reservation.
- Check that the available quantity went up.
Never cancel a reservation on a live order
You release goods promised to someone. They get sold twice and one of the orders cannot be fulfilled.
Requested versus reserved#
A reservation carries two figures: how much the customer wanted and how much could be reserved.
On a customer order those two should NOT differ
The e-shop refuses an order it cannot fully cover — a customer must not pay for uncovered goods. You will therefore see a gap only where partial reservation is deliberately allowed: on orders created in the administration, with Allow partial reservation switched on.
A gap on a customer order means something is wrong
Either somebody switched partial reservation on across the board, or the order did not come the usual way. It is worth finding out which — that is the difference between "we sell what we do not have" and "somebody bypassed the checkout".
