One platform. Replaces 6 fragmented tools.

Trello / Asana Practice Flow

Operations & Task Tracking

Say goodbye to generic boards. Get custom CA-specific Kanban boards pre-mapped to complex Indian filing schedules (GST, TDS, ITR, MCA) with built-in partner review gates and workload balance rules.

WhatsApp Business Nudge Engine

Client Communication

Stop chasing documents across personal chat threads. OperaBox automatically deploys coordinated WhatsApp, Email, and Portal nudges on your behalf, complete with scheduled escalation rules.

Google Drive / Dropbox Smart Vault

Document Management

Centralized, secure file vault equipped with real-time OCR parsing. Automatically detects duplicates, checks image legibility, inspects PDF passwords, and validates PAN/GSTIN data at intake.

Physical Registers AI Notice Chamber

Notice & Litigation Tracking

Eliminate manual diaries and Excel sheets. Instantly index incoming tax notices, auto-track deadlines, and generate highly professional, legally-sound draft responses via built-in AI models.

Excel Sheets & Razorpay Smart Billing

Billing & Collections

Stop leaving money on the table. OperaBox auto-generates professional invoices upon compliance filing, sends dynamic payment links, and initiates escalating payment reminder cycles.

Fragmented Emails Client Portal

White-Labeled Client Portal

Provide a secure, branded dashboard for your clients. They can check real-time filing statuses, upload requests, and access their historic tax returns 24/7 without calling your staff.

The practice is scaling. The operational blindspots are growing faster.

01
Operational Blindness
Filing deadlines are scattered across diaries, emails, and personal staff spreadsheets. You lack a centralized, real-time cockpit to monitor partner and branch workloads.
02
Communication Fragmentation
Staff waste hours chasing clients for files over personal WhatsApp accounts. Key documents get buried in scattered threads rather than linked directly to task logs.
03
Litigation Timeline Slip-ups
Incoming tax notices are managed in manual excel diaries. Critical response timelines slip, and historical notice trails are completely disconnected from client histories.
04
Practice Revenue Leakage
Compliance work is completed on time, but billing remains an afterthought. Invoices are dispatched weeks late, and collections rely on memory instead of automated reminders.
01 — Practice Operations & Capacity

Practice Operations, Unified. Every compliance task under total control.

Stop wondering who is working on what. OperaBox automatically generates monthly compliance tasks, balances resource routing based on active team workloads, and enforces partner-approved SOP checklists before any return is signed off.

  • Real-time Kanban workspaces tailored for GST, TDS, ITR, MCA, and Audits
  • Intelligent workload routing routes tasks dynamically to least-loaded staff
  • Automated SLA warning engine alerts partners of potential filing risks
  • SOP gatekeeper locks task closure until partner review is completed

02 — Client Communication & Portal Hub

Professional Client Experience. Stop chasing files — let automation handle it.

Say goodbye to fragmented email threads and personal WhatsApp chasing. OperaBox deploys unified, branded document requests that nudge clients across WhatsApp, email, and portal notifications on a coordinate schedule until they securely upload their files.

  • Multi-channel coordination: Synchronized reminders across WhatsApp, SMS, and Email
  • Intelligent escalation schedules trigger auto-nudges and partner warnings

03 — Intelligent Document Vault & AI Intake

Centralized Document Vault. Every file auto-verified at intake.

Protect your team's billable hours from corrupted, wrong, or duplicate documents. OperaBox runs real-time OCR parsing and cryptographic integrity checks at intake — automatically flagging unreadable images, identifying password protections, and extracting key registration numbers before they reach your staff's desk.

  • Cryptographic duplicate analysis blocks redundant uploads across financial years
  • Automated integrity check isolates corrupt or password-locked PDFs instantly
  • OCR metadata extraction auto-matches PAN, GSTIN, and statement dates
  • Self-correcting client nudges prompt instant re-uploads for failed files

04 — AI Notice Intelligence & Litigation Room

AI Notice Chamber. A tax notice lands — OperaBox processes it first.

Never scramble when a GST or Income Tax notice lands. OperaBox automatically ingests, analyzes, and archives notice workflows. Our integrated AI parses the legal allegations, isolates financial exposure, catalogs response deadlines, and drafts structured legal reply arguments for partner review.

  • AI-driven classification: Instantly parses Show Cause Notices (SCN), orders, and appeals
  • Auto-Timeline Mapping schedules response windows directly on partner calendars
  • Contextual Ground Drafts generate legally-grounded arguments pre-mapped to client ledgers
  • Unified litigation register links notices, reply histories, and outcomes to client profiles
