# How do a car dealership and a leasing company share customer data?

> The dealership and leasing company share customer data via a shared CRM platform where the contract is a single object with clear data segregation: the dealership owns the relationship and dialogue, while the leasing company owns the contract and financing. CARRUSLiNK acts as a neutral layer between them, so neither party has to provide raw databases, and the 90-day repurchase flow runs automatically based on the shared expiry date.

In practice, this means the dealership sees the customer record with contract length, expiry date, and vehicle history, while the leasing company sees portfolio, residual value, and payments in their own financing platform. Both parties are notified when a contract approaches expiry — the dealership needs to speak with the customer, and the leasing company needs to release the vehicle. Data exchange is role-based, not a monthly CSV export.

From a GDPR perspective, the contract is typically the lawful basis for processing, and each party is the data controller for its own part. CARRUSLiNK acts as a data processor for both – we never process data outside of the agreed purpose.
