Four systems, one source of truth: HubSpot visibility for one of Brazil’s largest vet networks
Reevia's customer ran its clinics on four systems that had never been connected. Four weeks later, every record flowed into HubSpot in under 50 seconds, and the business could see itself whole for the first time.


Results
- 2M+Records processed into one source of truth.
- Under 50sSource to HubSpot sync, end to end.
- 4 weeksFrom first message to production.
- 1stFull cross-system data visibility.
The problem
Every team had its own numbers. Clinical, scheduling, billing and marketing each lived in a different system. A customer could be three different people depending on who you asked. Reports were assembled by hand, disagreed with each other, and arrived too late to act on. Reevia needed all of it in HubSpot, where the sales and marketing teams already worked, without replacing any of the four systems and without a migration project that would take a year.
What we built
An integration service that pulls records from each source, deduplicates and maps them to one model, and writes them to HubSpot with every field traceable back to where it came from. Changes propagate in under 50 seconds, so what the team sees is what is happening now.
The build covered one identity per customer across four systems, every HubSpot field traceable to its source record, monitoring and alerts so a broken sync is seen before it is felt, and a runbook and hand-over for the customer’s team.
The result
More than two million records unified, a single customer view in HubSpot, and reports that nobody has to assemble by hand. In production four weeks after kickoff.
