FAQ
Do you build custom CRM and ERP systems?
Yes. We build fully custom CRM and ERP systems tailored to your business workflows — not off-the-shelf software. This includes user roles, dashboards, reporting, automation, API integrations and billing.
Can you build a multi-tenant SaaS platform?
Yes. Multi-tenant SaaS development is one of our specialties. We build subscription-based platforms with role-based access, admin panels, billing via Stripe, and scalable architecture ready for growth.
How long does a CRM or ERP system take to build?
A basic CRM with core modules takes 4-8 weeks. A full ERP or multi-module SaaS platform typically takes 3-6 months depending on complexity. We confirm timeline after a proper discovery session.
