Flagship product: Lander Books — accounting software for CA firms and auditors
Our flagship product, Lander Books, is cloud-based accounting software and practice management platform for chartered accountant firms, auditors, cooperative societies, and small businesses across India. Built from the ground up for how Indian CA practices actually work, Lander Books combines a full voucher and ledger system with work-item tracking, automatic invoice generation, a client portal (with WhatsApp/Telegram/Line uploads), configurable workflows, and multi-country tax compliance.
Lander Books ships in four purpose-built editions — For Auditors, For Cooperative Societies, Learning Management, and Multi-Entity SME — with data migration tools for Tally, Zoho Books, Xero, QuickBooks, and Vyapar. Firms are typically fully migrated within a few days.

Odoo and ERPNext ERP implementation
We implement, customise, and support Odoo and ERPNext for businesses across India. Typical engagements cover:
- Implementation from zero — configuration, custom modules, industry-specific tweaks
- Migration from legacy ERPs (Tally, SAP, or older Odoo/ERPNext versions)
- Custom modules built in Python/JavaScript (Odoo) or Frappe/Python (ERPNext)
- Integrations with payment gateways, e-invoicing, GST filing, WhatsApp Business, and more
- Long-term AMC and support once you’re live
Whether you need a standard Odoo deployment or a deeply customised ERPNext fork, we’ve shipped both — and we stay on as the long-term partner so your ERP evolves with your business.
Custom software development — web apps, mobile apps, SaaS
Beyond our products and ERP work, we build custom web applications, mobile apps, and SaaS platforms for startups, SMEs, and enterprises. Our stack:
- Backend: Python/Django, Node.js, PostgreSQL, Redis
- Frontend: React, Angular, Vue, Hugo (for static sites)
- Mobile: Flutter (cross-platform), native iOS and Android where needed
- Cloud: AWS, GCP, Dreamhost, self-hosted options
- DevOps: Docker, GitHub Actions, CI/CD pipelines
We take on end-to-end engagements — discovery, design, build, launch, and long-term support — not just delivery. Past industries include accounting and audit (Lander Books), glass container manufacturing (HECE — HotEnd ColdEnd Communicator), and film production (FilmiCall).
Based in Chennai, serving India and beyond
Landessware operates from Chrompet, Chennai, and works with clients across Tamil Nadu, Bangalore, Mumbai, Delhi, Hyderabad, Pune, and internationally (UAE, Thailand, Malaysia, USA — particularly for our NRI accounting practice clients). We’re open-source-first, documentation-heavy, and long-term-partner-oriented. Most client relationships run for years, not months.
