InvoiceOS — CA Firm Billing Suite
Billing that runs your CA firm. GST-compliant professional invoices, automated payment reminders, client-wise fee tracking, full audit log.
Everything Your Firm Needs to Bill, Track & Collect
Seven integrated modules that cover the full billing lifecycle for chartered accountant firms.
GST Invoice Engine
Auto-calculates CGST, SGST, and IGST based on client location. Bulk invoice generation for recurring engagements. Professional templates with your firm branding.
Automated Reminder Engine
Configurable escalation sequence: courtesy reminder, 7-day follow-up, 21-day formal notice, 45-day escalation. Never chase a payment manually again.
Time & Billing Tracker
Track billable hours per engagement. Staff timesheets auto-convert to invoice line items. Work-in-progress tracking keeps revenue recognition clean.
Aging & Receivables Dashboard
Real-time visibility into receivables by aging buckets: 0-30, 31-60, 61-90, and 90+ days. Drill down by client, partner, or service line.
Engagement & Retainer Management
Define annual engagement scope, set monthly or quarterly billing cycles, and log scope changes with full version history. Retainer drawdown tracking included.
Audit Log & Activity Trail
Immutable, timestamped log of every action — invoice creation, edits, approvals, payments. Fully DPDP-compliant for regulatory peace of mind.
Firm Revenue Analytics
Revenue breakdowns by service type, partner, client vertical, and period. Forecasting models help plan capacity and hiring decisions proactively.
The Reminder Engine That Actually Works
A structured 6-point follow-up sequence that recovers fees without damaging client relationships.
