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
  • Integration tests

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.
