Semantic HTML, JSON-LD schema, sitemap, geo-targeted meta — built to rank in Pune & across India.
Modern React, Node, cloud-native. Ready to scale from MVP to millions of users.
Every pixel hand-crafted. No cookie-cutter templates, no generic AI aesthetics.
AMC plans, WhatsApp support, monthly reports. We stay after the site goes live.

Trial balance, stock value and GST returns are matched line by line against your old system.
Final migration on a weekend or month-end, with rollback backups kept for 30 days.
Two weeks of hand-holding: report tweaks, user permissions, and printing/format fixes.
