Orders not syncing, payments failing, ERP flow breaking? Find the failure point
An order is placed but never reaches the ERP. A payment is confirmed by the gateway but the store still shows "pending." Courier labels fail to generate for every third shipment. These are not random glitches — they are symptoms of integration flows that were never properly validated end-to-end. An order flow audit traces each transaction from storefront to fulfillment, identifies where data is lost or delayed, and provides a concrete plan to fix the breakpoints.
The problem
Order processing in a modern eCommerce store is rarely a single system — it is a chain of handoffs between the storefront, payment provider, ERP, warehouse management, courier API, email service, and sometimes a marketplace or CRM on top. Each connection was built at a different time, by a different team, with different error handling assumptions. When one link in that chain silently fails — a webhook times out, a status mapping is wrong, a cron job skips a batch — the symptoms appear far downstream: missing invoices, double shipments, stuck orders, or refund discrepancies. Debugging these issues reactively, order by order, costs more in labor and customer trust than finding the root causes systematically. Without a map of the actual data flow and its failure modes, every fix is a guess and every peak sales period is a risk.
Scope of work
- Payment gateway flow analysis — tracing the full lifecycle from checkout initiation through provider callback to order status update, identifying timeout handling, retry logic, and status mapping gaps
- Courier and shipping integration review — label generation, tracking number sync, status callbacks, and error handling for failed or partial shipments
- ERP/WMS synchronization audit — order export, stock level sync, invoice generation, and return flow analysis including timing, batching, and conflict resolution
- Cron jobs and scheduled task validation — inventory of all recurring tasks related to order processing, assessment of execution reliability, overlap risks, and failure notification gaps
- Message queue and webhook inspection — delivery guarantees, retry policies, dead letter handling, payload validation, and idempotency of event consumers
- API retry logic and error handling review — assessment of how each integration handles timeouts, rate limits, malformed responses, and partial failures
- Status mapping and state transition audit — verification that order, payment, and fulfillment statuses are correctly translated between all connected systems without silent data loss
- Logging and alerting gap analysis — evaluation of what is currently observable in logs versus what should be, with focus on failure detection speed and traceability of individual transactions
What you get
- Integration failure map — visual diagram of the full order flow with failure points, risk severity, and data loss vectors annotated at each connection
- Prioritized fix list — actionable remediation items ranked by business impact, grouped into quick wins and structural improvements
- Monitoring gap analysis — specific recommendations for logging, alerting, and observability improvements that make future failures visible before customers notice
- Implementation brief — technical specifications for the highest-priority fixes, detailed enough for your development team to estimate and execute
- Recommended tooling and patterns — suggestions for message queue strategies, retry patterns, and integration testing approaches suited to your stack
When this is not the right fit
If your concern is purely about page load speed or general website performance without order processing symptoms, our Performance Optimization consulting is a better starting point. For analytics-only questions — conversion tracking, funnel visualization, or A/B testing — the Analytics and Conversions service covers that scope.
