Data Integration & Sync Implementation
Data Integration & Sync Implementation is a Data Hub engagement that connects your business systems to HubSpot: ERP, accounting, e-commerce, product databases. We choose per system between native sync, middleware like Make or n8n, and custom Node or Python integration, then build the connection with error handling that survives production.
The problem this solves
Customer data lives in four systems that disagree with each other. Someone retypes invoices from the ERP into the CRM, order status questions require logging into another tool, and when finance and sales compare numbers the meeting is about reconciliation instead of decisions. Every manual copy is a delay and a future data quality incident.
How we work
We map the integration per system, not per slogan: what object syncs, which direction, which system wins conflicts, how often, and at what volume. Then we pick the cheapest tool that does the job reliably: HubSpot native sync where a solid connector exists, Make or n8n where logic is needed without code, custom Node or Python services where volume, transformation, or an unusual API demands it.
We know the Polish stack from real projects: Symfonia, Comarch, Baselinker, Magento, KSeF, Fakturownia, GUS, alongside the international layer of Stripe, ERPs, and product databases. And we build for production, not demo day: idempotent writes, exponential backoff on transient failures, throttling that respects HubSpot API rate limits before they bite, alerting plus a runbook.
The result is data flowing where it belongs, automatically, with somebody notified when it does not.
Deliverables
- Integration map: objects, directions, conflict rules, volumes
- Tool decision per connection with documented rationale
- Configured native syncs and field mappings
- Custom middleware or code where scoped, with idempotency and retries
- Error handling, alerting, and a runbook for failures
- Handover documentation for your team or IT partner
What buyers ask before scoping.
Native connector, Make or n8n, or custom code - how do you decide?
Native sync wins when a good connector exists for your system and field-level mapping suffices. Make or n8n wins when you need transformation logic, lookups, or multi-step flows without maintaining code. Custom Node or Python wins on high volume, complex transformations, or awkward APIs. We document the reasoning per connection so the choice survives us.
How do you handle HubSpot API rate limits on high-volume syncs?
By throttling before the limit, not reacting after. We have hit HubSpot's rate limits on real migrations and learned the failure modes, including counter behavior that is genuinely unintuitive under load. Our integrations pace themselves against available capacity and back off exponentially on transient errors, so a busy day degrades gracefully instead of dropping records.
Is two-way sync safe, or should some connections stay one-way?
Two-way sync is powerful and dangerous in equal measure: without a clear source of truth per field, systems overwrite each other in loops. We default to one-way wherever the business allows and reserve two-way for objects with explicit conflict rules. That decision is part of the integration map, in writing.
