FAQ

Frequently asked questions

01How much does an integration cost?

A typical integration (payments, shipping, telephony) starts at $2,500. Complex ERP exchanges from $4,500. The estimate after API analysis is free.

02What if the service has no public API?

We find a way: file exchange, email parsing, RPA or direct database work. Truly hopeless cases are rare.

03How reliable is the data exchange?

Built with queues and retries: if a service is down, data is not lost — it is delivered after recovery. 99.9% SLA, monitoring and Telegram alerts.

04Do you support integrations after launch?

Yes — third-party APIs change, and unattended integrations break. We keep them monitored and updated.

05How long does it take?

A simple integration takes 2-3 weeks, a complex two-way exchange 4-8 weeks. Exact timing after reviewing the API docs.
