Physical stock, saleable stock and available-to-promise stock are related but different. Understanding the distinction helps avoid an online promise that the shop cannot fulfil.
Identify the authoritative record
Choose where stock counts are maintained and which systems read from it. If staff update several systems independently, discrepancies become difficult to explain. A clear source of truth does not have to mean a complex system, but it does require discipline.
Separate reservations from availability
An order being prepared may still be physically on the shelf. Reserve the relevant quantity so another customer cannot buy it unintentionally. Define when a reservation expires and what happens after a cancellation or failed payment.
Understand update frequency
An integration described as automated may still run periodically. Measure the actual delay and decide what the customer-facing stock figure should do during that interval. A buffer can help, but it is not a substitute for accurate receiving and counting.
Handle returns and adjustments deliberately
A returned product may be damaged, incomplete or awaiting inspection. Keep it out of saleable stock until the required check is complete. Record adjustments with a reason and an authorised staff member so recurring issues can be investigated.
Reconcile a sample regularly
Choose products with frequent sales or repeated exceptions and compare records with physical stock. Look for unit conversions, duplicate identifiers or missed receiving tasks. Fixing the source of a discrepancy is more useful than repeatedly correcting the number.
Take this into your next review.
Choose one real product and one realistic order. Walk through the steps with the people who do the work, record the gaps and agree who will resolve them.
