QUICK ANSWER
ERP and supplier feeds often include SKUs that no longer exist in the store. Without handling they cause errors, stuck queues and incomplete processing.
FROM OUR ENGINEERING WORKREAL CASE
An inventory feed regularly contained SKUs no longer in the catalogue. Handling them explicitly stopped errors and kept valid updates flowing.
KEY TAKEAWAYS
✓Feeds drift from the catalogue over time.
✓Unknown SKUs should be skipped and reported — not crash the run.
✓A regular mismatch report helps merchandising teams clean data.
What goes wrong
- Imports failing part-way through
- Queues retrying the same bad records
- Other valid updates never processed
- Logs flooded with noise
Handle them properly
Validate SKUs up front, skip unknown ones, continue processing and send a daily summary of unmatched SKUs to the team responsible.
Common mistakes to avoid
✕Choosing a platform on licence price instead of total cost of ownership
✕Launching a new site without an SEO redirect plan
✕Adding extensions and apps without checking performance or security
✕Leaving upgrades until peak season
