Connect commerce data without losing ownership or failure visibility.
For commerce teams integrating ERP, PIM, OMS, CRM, payments and logistics where duplicate data, silent failures or manual recovery disrupt operations.

Start with the business transaction and its owner.
- Typical first step
- Map one high-cost workflow end to end.
- Inputs we need
- Systems, owners, representative payloads, volumes, failure examples and access constraints.
- Outputs
- Source-of-truth map, contracts, delivery backlog and operating model.
- Working format
- Workshops with process owners plus focused engineering delivery.
Turn point-to-point connections into owned data flows.
- Different systems disagree on inventory or order state.
- Retries create duplicates or hide partial completion.
- Batch jobs fail without a clear recovery owner.
- Schema changes break downstream consumers.
- Each data domain has a named source of truth.
- Commands are idempotent and state changes are explicit.
- Retries, dead letters and reconciliation have procedures.
- Contracts and compatibility rules protect consumers.
The contract matters more than the connector.
Sync, async and batch patterns can coexist. We choose by consistency need, failure cost, volume and recovery behaviour.
Synchronous
Use when the caller needs an immediate authoritative answer.
Define timeout, fallback and partial-failure behaviour.Asynchronous
Use for durable workflows and independent processing.
Define ordering, idempotency, retry and dead-letter ownership.Batch / scheduled
Use for bulk exchange or systems without event APIs.
Define watermarking, validation, reconciliation and reruns.Integration scope from ownership to cutover.
System-of-record mapping
Ownership for product, price, stock, customer and order data.
Boundary: Business ownership must be named by the client.Contracts and schemas
Versioned payload and compatibility rules.
Boundary: Third-party API limits remain external constraints.Workflow orchestration
State transitions across commerce and operations.
Boundary: Business policy approval stays with process owners.Resilience controls
Idempotency, retries, dead letters and replay.
Boundary: No SLA is implied without a separate agreement.Cutover and reconciliation
Migration, parallel run and discrepancy handling.
Boundary: Source-data repair is scoped separately.Monitoring and ownership
Dashboards, alerts and failure routing.
Boundary: 24/7 response is excluded unless contracted.Map → Contract → Prove → Operate
Map
Workflows, owners, payloads and failure examples.
Trace data and decisions across systems.
Source-of-truth and failure map.
Contract
Rules, volumes and consumer constraints.
Define schemas, states and recovery semantics.
Versioned contracts and test cases.
Prove
Access, test data and cutover constraints.
Build thin flows and exercise failure modes.
Verified integration slice and cutover plan.
Operate
Production signals and ownership model.
Add monitoring, replay and reconciliation procedures.
Runbook and improvement backlog.
Example failure-ownership register.
Illustrative structure only — not a client case or a performance claim.

Team shape
An integration architect, backend engineers, quality specialist and source-system owners; the mix follows the flows and failure modes.
Code and IP
The client owns the project-specific code and agreed deliverables after payment; third-party licenses and pre-existing tools keep their original terms.
Handoff and support
Handoff includes agreed repositories, documentation and knowledge transfer. Ongoing support is a separate scope unless included in the engagement.
Not included by default
Replacement of ERP/PIM/OMS/CRM products, correction of all source data and continuous on-call support unless separately scoped.
Price factors
Systems and workflow count, API quality, data volume, consistency needs, historical migration, test environments and cutover constraints.
Start with one business transaction and its owner.
Which systems can you integrate?
ERP, PIM, OMS, CRM, payment, tax, logistics and marketplace systems where supported interfaces or controlled data exchange are available.
How do you prevent duplicate orders?
By combining idempotency keys, explicit state transitions, durable processing and reconciliation.
Do we need to replace existing systems?
Not by default. We first clarify ownership and improve the boundaries around systems that should remain.
Who handles failures after launch?
The operating model names the first responder and escalation path; ongoing response coverage requires an explicit support agreement.
Start with one business transaction and its owner.
After contact we trace its systems, data and failure paths, then define the next useful step.
