We've built a GST-compliant billing and accounting app for Indian SMEs and a cloud accounting platform for mid-size businesses both with AI-powered automation that reduces manual accounting work.
A full-featured billing and accounting application built for Indian small and medium businesses GST compliance, inventory tracking, vendor management, and AI-powered financial insights in a single product.
This is a Vyapar-class product built from scratch. The mobile app (Flutter, Android + iOS) is the primary surface for SME owners: create GST-compliant invoices across all formats (B2B, B2C, export, debit note, credit note), record expenses, manage inventory, track receivables and payables, add UPI QR codes to invoices, and share invoices directly via WhatsApp the distribution channel Indian SMEs actually use. The web dashboard (React) provides the accounting view: P&L report, GST summary for filing, TDS tracking, multi-user access with role-based permissions, and exportable reports for CA submission.
The backend runs on Java Spring Boot with PostgreSQL on AWS. GST calculation logic is implemented as a rules engine that handles CGST, SGST, IGST, and cess correctly based on the transaction type, the buyer's state, and the applicable HSN/SAC code. This is one of the genuinely hard parts of Indian accounting software the rules are numerous, state-specific, and subject to GST Council amendments.
AI capabilities built in: An expense categorisation model classifies bank statement transactions and manually entered expenses into the correct accounting head with 91% accuracy, eliminating the manual tagging that takes SME owners hours each month. A 30-day cash flow prediction model analyses outstanding receivables, upcoming payables, and historical payment patterns to show the owner where their cash position will be in 30 days. An automated GST filing assistant monitors return due dates, pre-fills GSTR-1 and GSTR-3B data from recorded transactions, and sends WhatsApp alerts when a return is approaching its deadline.
A QuickBooks-class accounting platform for mid-size Indian businesses multi-user, bank reconciliation, full financial reporting, purchase approval workflows, multi-currency, and AI-powered anomaly detection.
This platform serves businesses with 10-200 employees that have outgrown basic billing tools and need proper accounting controls. Core capabilities: multi-user access with role-based permissions (separate roles for data entry, accountant, manager, and auditor), bank reconciliation that auto-imports bank statements and matches transactions against recorded entries using fuzzy matching, P&L and balance sheet generation in real time, purchase order and approval workflow (PO raised → manager approval → vendor invoice match → payment authorisation), multi-currency support with daily exchange rate sync, and a full audit trail showing every modification with user, timestamp, and before/after values.
The frontend is React with a structured component library for consistent financial UI patterns. The backend is Node.js with PostgreSQL on Azure. Multi-tenancy is implemented at the schema level each company's data is completely isolated, which matters for chartered accountants managing multiple client accounts on the same platform.
AI capabilities built in: A transaction anomaly detection model flags unusual entries amounts that deviate significantly from historical patterns for that vendor, duplicate entries within a configurable window, round-number entries that are common in manual data entry fraud, and supplier invoices without corresponding POs. A predictive invoicing model tracks project completion signals (milestone approvals, delivery confirmations) and suggests when to raise client invoices to optimise cash collection. The same expense categorisation ML model from the SME app is used here, trained additionally on mid-market transaction patterns.
These are production features that users interact with daily not demos.
A classification model trained on Indian accounting chart-of-accounts patterns reads transaction descriptions and amounts, then assigns the correct accounting head automatically. Works for both bank statement imports and manually entered expenses. The model was fine-tuned on domain-specific Indian business terminology (e.g. "GST challan", "TDS payment", "advance to vendor") that generic NLP models handle poorly.
Production accuracy: 91% correct on first classification
The model analyses all outstanding receivables (with their due dates and customer payment history), upcoming payable obligations (vendor invoices, loan EMIs, salary dates), and bank balance to project the business's cash position for each of the next 30 days. Owners can see at a glance if they'll have a cash gap on a specific date and take action collect earlier, delay a discretionary payment, or draw on a line of credit.
Outcome: proactive cash gap identification before it becomes a crisis
In the cloud accounting platform, a monitoring model runs on every new transaction entry. It flags: amounts that are more than 3 standard deviations from the norm for that vendor, entries that appear to be duplicates within a 7-day window (same vendor, same amount), round-number entries above a configurable threshold (a common pattern in manual fraud), and supplier invoices with no corresponding PO in the system. Flagged items appear in an "exceptions" queue for accountant review.
Outcome: systematic catch of data entry errors and suspicious patterns
The assistant monitors GST return due dates against the company's GST registration type, sends WhatsApp + in-app reminders 10 days and 3 days before each deadline, and pre-populates GSTR-1 and GSTR-3B data from transactions recorded in the billing app. The user reviews and submits rather than building from scratch. Built to handle HSN-wise summary, B2B vs B2C breakdowns, and amendment returns for previous-period corrections.
Outcome: zero missed GST deadlines for users who enable alerts
GST invoice generation across all formats, e-invoice (IRN) integration, e-way bill generation, GST return data preparation, and TDS tracking. Built to handle the full complexity of Indian GST compliance.
Multi-user accounting systems with bank reconciliation, purchase order workflows, P&L and balance sheet reporting, audit trail, and multi-currency support. Suitable for mid-size businesses that have outgrown Tally.
UPI QR on invoices, payment link generation, automatic payment reconciliation against outstanding invoices, and collection reminder automation via WhatsApp and SMS.
Loan origination workflows, credit scoring integrations, repayment schedule tracking, NPA flagging, and collections management for NBFCs, fintech lenders, and businesses offering credit to their dealers or customers.
TDS, TCS, and advance tax tracking. MSME-compliant payment terms tracking. ROC-ready financial statement formats. Compliance calendar with automated alerts for all filings no missed deadlines.
Expense categorisation ML, cash flow forecasting, anomaly detection, and predictive invoicing all built and productionised as part of your accounting platform, not bolted on as a separate product.
We understand Indian GST compliance, UPI payments, and the accounting patterns of Indian SMEs and enterprises. We've shipped two complete financial products we can build yours too.
