ERP and CRM systems often end up out of sync, with sales, finance, and operations each trusting a different version of the truth. Reliable integration comes down to a few consistent principles.
One system of record per type of data
Deciding explicitly which system owns customer data, which owns financial data, and how updates flow between them prevents the conflicting-record problem that causes most integration headaches.
Handling failure, not just the happy path
Integrations fail in production. Building in retries, clear error logging, and a way for someone to notice and fix a stuck record quickly is what separates an integration that stays reliable from one that quietly drifts out of sync.
Getting these fundamentals right matters more than which specific middleware or connector is used to move the data.
