Why point-to-point integrations become expensive
· 4 min read · LT Lab
Each direct connection seems simple on its own. Together they become fragile. A central integration layer is often cheaper over time.
The first integration is usually straightforward: connect the CRM to the accounting system. Then the e-commerce platform needs to talk to both. Then the payment provider, the HR system and a reporting database. Each connection is built separately, often by different people.
The hidden cost
Point-to-point integrations duplicate business rules, handle errors inconsistently and are difficult to monitor. When one system changes, several connections break at once, and nobody has a complete picture of what data moves where.
What an integration layer provides
- One place for data mapping and validation rules
- Consistent retries, queuing and error handling
- Logs that show what moved, when and why it failed
- Easier replacement of a system without rewriting every connection
It does not need to be heavy
An integration layer can be a small, well-structured service with a database and a queue. The architecture matters more than the size. Starting with this pattern early prevents a costly rebuild later.
