FAQ
How will you stop duplicate SKUs from updating the wrong Shopify variants?
I check SKU uniqueness, variant IDs and supplier references before mapping products. Duplicate or missing SKUs are flagged for review so Shopify inventory sync does not rely on ambiguous matches.
What happens when two suppliers provide stock for the same Shopify product?
We define supplier priority, fallback rules or combined stock calculations. The stock sync follows that agreed logic so competing feeds do not repeatedly overwrite the same inventory.
How do you prevent overselling when supplier stock updates are delayed?
I can configure stock buffers, low-stock cutoffs and update schedules based on feed availability. These reduce overselling risk, though supplier delays and simultaneous purchases can still affect availability.
Will Shopify API rate limits cause missing inventory or product updates?
I design Shopify API integration around request limits, batching and retry handling. Failed updates can be logged and retried without restarting the entire product sync.
What happens if my supplier API goes offline or returns an incomplete feed?
I can add validation to reject empty or incomplete feeds, preserve the last accepted stock values and flag failures. We agree when outdated inventory should trigger a stock cutoff or manual review.
Can inventory sync overwrite my Shopify titles, images or manually edited prices?
We define which fields the supplier controls before setup. Product sync can update only approved fields, such as inventory and cost, while preserving your store’s titles, images and other manual edits.
How will inventory automation handle bundles that share the same components?
For supported bundle setups, availability is calculated from component quantities and units required per bundle. Shared components need coordinated deductions to avoid showing the same stock as available twice.
How do you handle duplicate or out-of-order Shopify webhook events?
Where supported, I use event IDs, timestamps and duplicate checks so repeated events do not apply twice. For stock updates, fetching the current source value can prevent older events from restoring stale quantities.
How are cancellations, refunds and returns handled during Shopify stock sync?
We define when inventory should be restored and which system controls it. A refund does not always mean an item is restocked, so automation must follow the actual return and fulfillment status.
Who owns the integration, and are there ongoing app or hosting costs?
I confirm where the integration runs, required subscriptions and access ownership before ordering. Custom code and handover deliverables are agreed in scope; third-party app, hosting and usage fees are separate.
