Quick answer
LaSyncro tracks inventory using several quantities that describe what is physically present and what is still available for new order demand.
The main quantities are On-hand, Reserved, and Available.
On-hand
On-hand is the physical quantity currently recorded in warehouse inventory.
For example, if a bin contains 12 recorded units of a variant, its on-hand quantity is 12.
On-hand includes units that may already be reserved for released orders.
Reserved
Reserved inventory is part of your on-hand stock that has been held for order demand.
Reserved units are still physically in the warehouse, but they are no longer available for another reservation.
Available
Available is the inventory that remains after reservations are taken into account.
In the current inventory model:
Available = On-hand - Reserved
For example:
- On-hand: 12
- Reserved: 4
- Available: 8
Sellable
LaSyncro also stores a Sellable quantity.
In the current inventory model, Sellable is derived from Available and has the same quantity.
What about Committed?
Committed is retained internally for schema compatibility but is not a separate active inventory stage in the current model.
Order commitment is represented through inventory reservations instead.
For day-to-day warehouse decisions, focus on On-hand, Reserved, and Available.
No inventory record is different from zero inventory
LaSyncro distinguishes between:
- a product variant that has an inventory record with a quantity of zero;
- a product variant that has never been received into warehouse inventory.
A product with no warehouse inventory record is treated as not yet received, not simply as an ordinary zero-stock record.
