“The assessment caught our payment webhook retries creating ghost fulfillments. We still wish the remediation list had been shorter, but the severity ranking helped us fix the warehouse clashes first.”
Client stories
Evidence from engagements where connectors, stock, and feeds had to hold under campaign pressure.
“Inventory sync architecture sessions gave us a reservation window that finally held during our Lunar New Year flash sale. Pickers stopped finding empty bins for orders already paid.”
“Feed mapping work stopped our Shopee rejects from stacking up every campaign week. Merchandisers now edit a table instead of waiting on a hotfix.”
“Checkout connector design clarified which callbacks we must acknowledge before stock is released. It took longer than I hoped to schedule the workshops, yet the payment edge cases stopped waking us at midnight.”
Extended note: apparel brand webhook cleanup
A Taichung apparel team came to us after warehouse pickers kept finding duplicate pick tickets for the same paid order. The integration assessment traced the issue to payment provider retries that created a second fulfillment job whenever the first acknowledgment timed out.
We ranked the webhook listener first, documented an idempotency key tied to the provider event ID, and postponed a larger ERP rewrite. Within one release cycle the ghost tickets stopped. The team still maintains a weekly reconciliation report for edge cases — a mild ongoing cost they accepted rather than claiming the problem vanished entirely.
