System-to-System Integration
Connect ERP, CRM, and e-commerce with robust code.
Custom integration between two or more systems (ERP, CRM, e-commerce, accounting, marketing, HR) with bidirectional sync, validations, idempotency, and observability. Unlike visual flows, this is hardened code for complex logic and high reliability.
Who it's for
- Companies running multiple systems that don't talk to each other
- Migrations to a new ERP or CRM with historical data
- Marketing platform to sales CRM sync
- E-commerce to accounting with LATAM e-invoicing
- Teams with integrations that periodically break
What's included
- Discovery, entity mapping, and business rules
- Architecture design (sync vs async, push vs pull)
- Connectors via API, webhooks, direct DB, or file
- Field mapping and transformations
- Validation and business rules
- Idempotency, retries, and dead-letter queue
- Full initial sync (backfill)
- Incremental delta sync
- Conflict resolution
- Observability, alerting, and health dashboard
- Operational runbooks

Your CRM says one thing, your ERP another, and someone copies data between them. Errors, latency, lying reports. We build the bridge: bidirectional, validated, observable, and idempotent. Data flows on its own and reporting stops lying.
