How to connect a company's systems and avoid duplicate data entry
If the same data is entered twice, there is an integration problem. How systems are connected and where to start.

The symptom is always the same: the same data entered in two systems, reports assembled by combining exports, and numbers that never match across teams. The cause: systems that do not talk to each other.
What integration means
That systems exchange information automatically. The most common mechanism is the API: a door each system offers so others can query it or send it data. When there is no API, alternatives exist: files, intermediate databases, interface automation.
A method that works
- Map the workflow: where each data point is born and where it needs to go.
- Choose the source of truth for each data point: a single place where it is entered.
- Connect the systems so the rest updates on its own.
- Monitor: if a connection fails, the system alerts before operations notice.
Where to start
With the most frequent duplicate entry: it is usually the integration with the highest return and the one that organizes the rest of the workflow. You do not need to integrate everything at once; integrations are built in stages, each useful on its own.
