Custom Software Development Company in India

ERP, HRMS, billing and operations software built in Dehradun around Indian tax, payroll and compliance rules, with full source code ownership.

Custom Software Development for India

Custom Software Development, built around how India works

Indian businesses face rules that generic global software often handles poorly: GST with its intra-state and inter-state splits, e-invoicing and e-way bills, TDS, PF and ESI deductions, state-specific professional tax and the DPDP Act. When software does not fit, teams fall back on Excel and WhatsApp, and errors surface at audit time. Custom software built for these rules removes that friction.

Nexzem builds custom systems from our Dehradun office for manufacturers, distributors, schools, hospitals and service firms. Being in Uttarakhand, we are close to the industrial estates around Haridwar, Selaqui and Pantnagar, and can visit sites in the region to see workflows first-hand. For other cities we run discovery remotely, in the same time zone.

Finance, GST and Tally

Billing modules generate GST invoices with GSTIN, HSN or SAC codes and the right CGST, SGST or IGST split by place of supply, report invoices to the Invoice Registration Portal where e-invoicing applies, and create e-way bills for goods movement. TDS and TCS handling, credit notes and multi-branch numbering series are built in. Accounting can stay in Tally or Zoho Books, with the custom system syncing vouchers automatically. This is general information, not legal advice.

HR and payroll for Indian rules

Payroll and HRMS software for India handle details global tools often miss. Because labor rules change, including the move to consolidated labor codes, salary structures and deductions are configurable rather than hardcoded.

  • PF and ESI calculations with EPFO and ESIC upload files
  • State-wise professional tax and labor welfare fund slabs
  • TDS on salary with old and new regime choices and Form 16 data
  • Shift, overtime and attendance rules for factories and field staff
  • Hindi interfaces for shop floor and field employees

Built for multi-location operations

Distributors, manufacturers and chains need software that works across branches with uneven connectivity. We design for offline data entry at sites, WhatsApp alerts for approvals and exceptions, role-based access per branch and dashboards for owners who check numbers on their phones. Where an older desktop system is in place, we plan a staged legacy modernization.

Custom Software Development in India, answered

Something else on your mind? Ask a consultant and get a reply within one business day.

Should we buy an ERP or build custom software?

If a standard ERP such as Tally, Zoho or Odoo covers most of your process, start there and build only the missing pieces. Custom software makes sense when your workflow is unusual, when you pay for several tools that still need manual work, or when the process is a competitive advantage. Our SaaS vs custom software comparison goes deeper.

Can you visit our factory or office during discovery?

For businesses in Uttarakhand and nearby, site visits during discovery are practical and often useful for understanding shop floor workflows. For clients in other cities, we usually run discovery over video with recorded walkthroughs, and in-person sessions can happen at our Dehradun office.

Will we own the source code?

Yes. We sign a mutual NDA before detailed discussions, and all source code, designs and documentation are assigned to your company. Code lives in a repository under your account, and hosting is set up in your cloud account, so you can bring development in-house at any time.
