FAQ

How long does a project take?

Simple site 7-30 days, corporate site 30-60 days, ERP/CRM 2-6 months, mobile app 2-4 months. We give exact timeline after reviewing your spec.

Why custom instead of off-the-shelf?

SaaS solutions (Bitrix, Shopify, WordPress) cover 80% of standard cases. But the 20% that doesn't fit is what makes you different from competitors. Custom invests in that 20%.

What about post-launch support?

3-6 months free support is included. After that, monthly SLA (critical bugs = 4 hours, minor fixes = 24 hours).
