Integrations that join separate systems into one process

We design the API exchange and backend logic so that data moves predictably: with statuses, logs, error handling and documentation you can actually read.

Why this task comes up

A business often grows faster than its systems. The website lives on its own, so does the CRM, so do payments, so do the reports. People end up moving data by hand, errors surface late, and nobody can tell where exactly the process broke. Integration is not needed “to connect the services” — it is needed to make the movement of data manageable.

When to get in touch

  • Data has to be carried between systems by hand.
  • Requests, payments, statuses or documents drift apart across services.
  • There are no logs, so errors are hard to find and harder to recover from.
  • An integration exists, but it works as a black box.
  • You need a backend for a website, a portal, the CRM or analytics.
  • The system depends on ad-hoc exports, spreadsheets and manual reconciliation.

What Aivex does

Aivex designs the integration as part of the business process: which events occur, which data is passed, where a status is needed, what to do on failure and who should see the result. That turns the exchange from a purely technical thing into a manageable one.

  • design of the API exchange and its events
  • backend logic and data processing
  • integrations with CRM, ERP, payments, databases and external APIs
  • statuses, queues, retries and error handling
  • logs, monitoring and documentation
  • admin interfaces for oversight
  • preparing data for analytics and dashboards

How we work

  1. We describe the business events and the points of exchange.

  2. We define the sources, data formats, statuses and failure modes.

  3. We design the backend logic and the integration scheme.

  4. We build the API, the handlers, the logs and the control scenarios.

  5. We test the real cases: success, failure, duplicate, retry, recovery.

What the client gets

  • systems exchange data without anyone moving it by hand
  • errors can be seen, understood and recovered from
  • the business process becomes more predictable
  • the team depends less on spreadsheets and exports
  • a base for automation and analytics appears

What it looks like in practice

The website, the CRM and an internal system kept disagreeing about statuses. Aivex described the events, designed the API exchange and added backend logic, error handling and logs. Data started moving predictably, and failures stopped being invisible.

Frequently asked questions

Can systems be integrated without rebuilding everything?

Yes. It is often enough to design the right exchange layer and connect the sources one by one.

Which matters more — the API or the process logic?

The process logic. The API is a tool. Without an understanding of events, statuses and failures, an integration turns into chaos fast.

Is documentation necessary?

Yes. An undocumented integration is hard to support and dangerous to build on.
