CRM software
Leads, sales pipeline, follow-up reminders, quotations and team performance reports, with WhatsApp and email logging.
Overview
Custom Business Software built around your business.
Off-the-shelf software is built for everyone, which often means it fits nobody well. KenStack is a custom software development company that builds business software around how your company actually sells, buys, produces, bills and reports.
We build CRM software for leads and follow-ups, accounts and GST billing software for quotations, invoices and receipts, inventory and ERP software for stock across locations, HRMS for attendance and leave, POS software for counter billing, and estimation software for contractors and builders. Each module can run on its own or share one database with the others.
Because the software is yours, there are no per-user licence fees and no features you pay for but never use. You own the source code, your data stays on your server or cloud account, and we can extend the system with new modules, reports, mobile access and AI features as your business grows.

FAQ
Custom Business Software: common questions
Is custom software better than ready-made software?
Ready-made software is quick to start but forces your team to adapt to it. Custom software costs more up front but fits your process, has no per-user fees and can be extended freely, which often makes it cheaper over three to five years.
Can you build GST-compliant billing software?
Yes. We build quotations, tax invoices, receipts and credit notes with GSTIN, HSN or SAC codes, CGST, SGST and IGST splits, amount in words and printable PDFs, along with GST reports.
Can you migrate data from Excel or Tally?
Yes. We import customers, products, stock and opening balances from Excel, CSV or exports from your current software, and can sync with Tally where required.
Do you provide training and support?
Yes. Every project includes user training, documentation and a warranty period, followed by optional monthly support for updates and new features.
