Two-way sync is one of those engineering problems that looks simple from the outside and quietly wrecks projects from the inside. The trick is in the conflicts.

## Pick a System of Record

Every entity needs a designated source of truth. Contacts live in your CRM. Invoices live in Stripe. Tasks live in Asana. Without that decision, every tool starts arguing.

## Conflict Resolution Strategy

When two systems disagree, who wins? Last-write-wins, source-of-truth-wins, or human-resolves? Pick the rule before you ship the integration.

## Observability Beats Cleverness

Log every sync, alert on every failure, and build a manual override panel from day one. The team that can see what happened is the team that can fix it fast.
