Frequently asked questions
Why build a custom CRM instead of purchasing Salesforce or HubSpot?
Off-the-shelf CRMs charge per seat. As your sales department scales to dozens of agents, these monthly costs rapidly balloon. Furthermore, these platforms restrict your customization capabilities unless you upgrade to complex enterprise plans. A custom CRM offers a flat-rate infrastructure cost, 100% database sovereignty, and features crafted specifically for your team's workflow.
How secure is our customer data in a custom CRM?
Extremely secure. We implement advanced PostgreSQL Row-Level Security (RLS), encrypt sensitive personal information at rest, require secure token-based logins, and deploy server APIs behind rigid Web Application Firewalls (WAFs).
Can we migrate our historical data from spreadsheets?
Yes. We clean, normalize, and format your old CSV files, matching historical transaction logs, contact information, and email histories into your new structured relational database cleanly.
What backend frameworks do you use to build CRMs?
We utilize robust enterprise technologies: Next.js (React) for fast visual interfaces, Node.js or Python API middleware, PostgreSQL or AWS RDS for relational databases, and Vercel/AWS for deployment.
How long does a custom CRM development project take?
A modular custom CRM with pipeline grids and contact sheets takes 6-8 weeks. Complex, multi-branch CRMs with invoicing, dialers, and advanced client portals take 10-14 weeks.
