Accounting Software Development
Custom accounting platforms with GST, TDS, and audit trails built in.
Overview
We develop accounting software on a proper double-entry ledger engine: GST returns and e-invoicing through the IRP, TDS handling, bank reconciliation with statement feeds, receivables and payables ageing, and financial statements from trial balance to balance sheet. Where businesses keep Tally for statutory comfort, we build two-way integrations rather than forcing a switch.
Chartered-accountant firms in Kolkata, trading houses across West Bengal, and finance teams around India use accounting systems we have written, tuned to Indian tax law with a depth generic global products rarely offer.

Technologies we use
Why choose BetaZen
Books that balance themselves
Every transaction posts as balanced double entries with an immutable audit trail, so the trial balance is always a report away — never a reconciliation project.
GST filings from live data
GSTR-1 and GSTR-3B data assembles from actual invoices with mismatch flags raised early, shrinking month-end filing from days to minutes.
Built around your CA
Auditor-friendly exports, Tally sync, and period locks mean your chartered accountant works with the system, not around it.
How we work
Discovery & Strategy
We start by understanding your goals, users, and constraints, then map the fastest path to measurable outcomes.
Design & Architecture
We design the experience and the system architecture up front so what we build scales cleanly and predictably.
Agile Delivery
We ship in short, reviewable increments with continuous testing so you see working software early and often.
Launch & Support
We handle deployment, monitoring, and handover — and stay on to iterate, optimize, and support post-launch.
Frequently asked questions
Do you understand Indian requirements like GST, TDS, and Tally workflows?
Deeply — it is the core of this service. Being a Kolkata firm, we build for Indian statutory reality first: GST return structures, e-invoice schemas, TDS sections, and the Tally-centred habits of Indian accountants.
Why build accounting software instead of buying it?
Businesses choose custom when their billing logic, industry pricing, or multi-entity structure will not fit packaged tools, or when accounting must live inside a larger platform — an ERP, marketplace, or SaaS product — as a native module.
Is our financial data safe in a custom system?
Yes — encrypted storage and transport, role-based access with maker-checker options, daily automated backups, and full audit logs. You also control where data lives: your servers, Indian cloud regions, or both.
Can it start mid-financial-year?
Yes. We import opening balances and year-to-date transactions from your current books, run both systems in parallel for a verification period, and cut over cleanly at a month boundary.
