The Four Infrastructure Problems Every CA Firm Faces
Every growing CA firm reaches the same four infrastructure problems at roughly the same growth stage — typically when the team exceeds four people and client count exceeds thirty.
Problem 1 — Concurrent access limitations: The firm's Tally server cannot handle 5 staff simultaneously without slowdowns, crashes, or file locking conflicts. Staff are told to stagger Tally usage — reducing productivity and creating coordination overhead.
Problem 2 — Partner remote access: Senior partners need to review financials and approve returns from home. VPN setups are fragile and break regularly. Carrying client data on personal laptops creates compliance and security risk.
Problem 3 — GST filing season overload: The last 2 days before GST deadlines expose every infrastructure weakness. Servers slow down. Files get corrupted. These crises repeat quarterly.
Problem 4 — Staff growth outpaces infrastructure: Each new hire needs Tally access. Adding users to a local server means buying hardware or asking IT to reconfigure a struggling setup.
A properly configured Windows cloud server from M A Global Network resolves all four simultaneously.
GST Filing Season — The Infrastructure Stress Test
GST filing deadlines are the annual stress test for every CA firm's infrastructure. The workload characteristics: everyone in Tally at once, I/O-intensive GSTR-2A/2B reconciliation running simultaneously across multiple users, zero tolerance for downtime, and evening/weekend hours requiring available support.
M A Global Network's infrastructure is specifically provisioned for this workload. Dedicated (not burstable) CPU and RAM means filing season performance is identical to a quiet Tuesday — other customers' peak usage does not affect your resources. NVMe SSD handles concurrent I/O without queuing. 99.9% uptime SLA. 24/7 phone support at 11 PM on the 19th.
Multi-Company Architecture — Technical Details
Tally's internal architecture supports unlimited company files on a single installation. A CA firm managing 70 client companies uses one Windows Server 2022 instance. Each staff member's RDP session is isolated at the OS level — if one staff member's session crashes, the other four continue working unaffected.
A CA firm with 70 client Tally companies averaging 3 years of data typically needs 80–150 GB of storage. M A Global Network's plans include ample NVMe SSD storage. Firms with extensive archived data may need additional storage, provisioned transparently. Storage requirements are assessed during the pre-migration call — no surprise charges.
Client Data Isolation — Three Independent Layers
Layer 1 — Network firewall: Only authorised IPs can initiate RDP connections. An internet-facing Windows Server without IP whitelisting receives thousands of automated connection attempts daily — whitelisting reduces this to zero.
Layer 2 — Windows user accounts: Each staff member has a dedicated Windows account. Sessions isolated at OS level. Administrator access restricted to M A Global Network's management accounts for server maintenance — not firm staff.
Layer 3 — Tally company-level access control: Tally's built-in security restricts which users can open which client companies. Staff A handles Clients 1–15 and cannot open Companies 16+. Configured within Tally itself and travels with the cloud migration.
DPDPA 2023 — Practical Compliance Considerations
India's Digital Personal Data Protection Act 2023 increases obligations around client financial data. A managed cloud server provides stronger technical protections than a typical CA firm's local setup:
- IP-whitelisted access with access logs — documented access control evidence
- Encrypted transmission (TLS) — data in transit protection
- Daily backups with tested restoration — data availability and integrity
- Regular OS patching — vulnerability management
- No client data on personal devices — reduced exposure surface
All of these are included in the ₹700/user/month managed service. Consult your legal adviser for firm-specific DPDPA guidance.
Pricing for CA Firm Configurations
| Firm Configuration | Concurrent Users | Monthly Cost |
|---|---|---|

| Small firm (2–3 partners + 2–3 staff) | 4–5 users | ₹2,800 – ₹3,500/month |
| Typical CA firm (3–4 partners + 4–6 staff) | 6–8 users | ₹4,200 – ₹5,600/month |
| Large CA firm (multi-office) | 10–15 users | ₹7,000 – ₹10,500/month |
Frequently Asked Questions — CA Firms
Yes, in almost all cases. TDL-based tools — GST filing utilities, e-invoice generation tools, audit tools, custom report packs — install on the Windows Server exactly as on a local Tally installation. M A Global Network migrates and verifies all TDL files during onboarding. Updates are applied by our team on the server side.
Most CA firm migrations with 30–60 client companies complete within 48 hours scheduled over a weekend. Firms with very large individual company files, complex multi-TDL environments, or 100+ client companies may require 72–96 hours. Timeline is assessed accurately during the pre-migration call. The firm's staff take no action during migration — our team handles everything.
Yes. You can create a Windows user account for specific clients and restrict that account to only their Tally company files. The client connects via RDP and sees only their company data. This is a common setup for CA firms whose larger clients want direct access for day-to-day entries while the firm handles filing and compliance.
