Data Synchronization Policy

A data synchronization policy is the documented set of rules governing what data syncs, in which direction, and how often between two systems.

It sits above the transfer mechanics: the policy is the agreement, while the sync engine executes it.

A practical example

Example: a policy states leads flow from the marketing platform to the CRM only, contacts sync bidirectionally nightly, and no field is ever overwritten by the CRM side.

What to evaluate before investing

  • Confirm the platform can enforce your direction and frequency rules, including one-way restrictions.
  • Check whether field-level conflict rules, such as system-of-record designations, are configurable.
  • Ask how the policy is documented and who approves changes before they take effect.

Limitations and tradeoffs

Teams often discover unidirectional limits or overwrite behavior only after go-live, because the policy was assumed rather than written down and tested against the platform's actual capabilities.
