Four systems, one source of truth: HubSpot visibility for one of Brazil's largest vet networks
Built a custom integration layer for Reevia that connects four source systems into HubSpot for one of Brazil's largest veterinary companies. Over 2 million records processed with full normalization. Any lead from any system is inside HubSpot in under 50 seconds, standardized and ready to use.
For the first time, our teams all work from the same data. The integration runs silently in the background and just works.
The client ran four different software platforms, each managing a separate part of the business. HubSpot was in place but the data never reached it in usable shape. Records arrived raw, inconsistently formatted, and with no shared identifiers across systems. Marketing, sales, relationship, and pre-sales teams worked from separate, incomplete views. There were no shared pipelines, no cross-system visibility, and no way to follow a contact's full journey across the organization.
Built a custom integration layer that connects all four source systems to HubSpot. The system pulls data in batches via HTTP, normalizes and maps each record to the correct HubSpot object type, and upserts them with full association handling. Every ingestion cycle is logged and auditable: teams can trace any HubSpot record back to its source batch and original payload. A sync control panel lets the team pause ingestion per source, monitor pipeline health, and inspect individual records end to end. Any lead captured in any of the four systems reaches HubSpot in under 50 seconds.
Next.js with TypeScript for the admin panel, deployed on Vercel. Node.js backend handling batch ingestion, data normalization, and HubSpot upsert logic via the official HubSpot API. Custom mapping layer per source system and object type. Full audit trail with batch tracking, source record linking, and end-to-end record status. Delivered as a dedicated integration service for Reevia.
