Integration first: connect the systems you have before you build new ones
Many “we need a new platform” projects are really integration problems. Connecting what already works is often faster, cheaper and less risky.

The hidden cost of re-typing
In most growing companies, orders, invoices and customer records pass through several systems: a shop, an ERP, a CRM, a warehouse tool, the bank. Wherever a person copies data from one to another, you pay in time, errors and delays, and nobody has one view of the truth.
Before deciding to build or buy a new platform, map those hand-offs. The map often shows that the systems themselves are fine; the gaps between them are the problem.
Design for failure
Every external system will eventually time out, change a field or go down for maintenance. Good integrations expect this. They queue messages, retry with back-off, alert a person when something cannot be fixed automatically, and keep a log of every message so you can answer “what happened to order 4821?” in seconds.
When to build instead
Sometimes a legacy system cannot be connected cleanly, or the process it enforces is the problem. Then a new application is the right call, and it should be built with clean APIs from the start so the next integration is easy. The decision is economic: connect when connecting is cheaper, rebuild when it is not.
