Can you integrate a system with no API?

Usually yes. Older systems are commonly reached through scheduled file exchange, database access, or a message queue. It is less elegant but entirely workable, and we will be clear about the trade-offs before committing.

How do you handle data that disagrees between systems?

By deciding, explicitly and with you, which system is authoritative for each field before writing any code. Most integration pain comes from that decision being made implicitly.

Do you support the integration after it ships?

We can. Integrations break when systems on either end change, so ongoing support is often worth more than the initial build. Alternatively we hand over with documentation and runbooks.

System Integration

System integration is the work of making separate systems behave as one — moving data between an ERP, a CRM, a payment provider, and whatever else the business runs on, reliably enough that nobody re-keys it by hand. The hard part is almost never the happy path. It is what happens when one system is down, slow, or returns something unexpected.

What integration work usually looks like

Most integration projects start because someone is copying data between systems manually, and the cost of that has finally become visible.

ERP and accounting systems that need order and inventory data from elsewhere.
Payment providers, where correctness and reconciliation matter more than speed.
CRM and marketing tools that need a trustworthy customer record.
Legacy systems with no modern API, reached through files, queues, or a database.

Designing for the unhappy path

An integration that only works when every system is healthy is not finished. We design for partial failure from the start, because in production it is the normal condition rather than the exception.

Idempotent operations, so a retry cannot double-charge or duplicate an order.
Explicit retry and backoff rules rather than hoping the next attempt succeeds.
Dead-letter handling so failed messages are visible instead of silently lost.
Reconciliation checks that catch drift between systems before a customer does.

Making it observable

When an integration misbehaves, the first question is always where a record stopped. If answering that means reading logs on four systems, incidents take hours instead of minutes. We instrument the flow end to end so that question has a single answer.
