The Problem

Client management is
draining your firm's energy.

Every Indian CA firm hits the same four walls. Here's what you're dealing with — before TaxDost.

📄

"Sir, where is my document?"

You receive the same document request dozens of times a week. Finding files, sending PDFs manually — hours lost every filing season.

⏰

Deadline chaos every quarter.

GST, TDS, advance tax — you cannot manually remind 200+ clients. Missed dates mean penalties and furious calls at midnight.

📞

Appointments that never happen.

Clients call at odd hours to schedule meetings. You forget, they forget. Double bookings, no-shows, wasted calendar slots.

🌙

No off-hours? There shouldn't be.

A client messages at 11 PM asking a basic tax question. You either ignore it (bad) or reply every single night (exhausting).

🔴 HIGH SCRUTINY RISK — ACTION REQUIRED

4 Compliance Anomalies Detected in Working Papers

₹1,24,600 Tax At Risk ₹58,000 Blocked Sec 17(5) 1 Supplier Missing in 2B

HIGH SEVERITY SECTION 17(5) INELIGIBLE ITC Blocked Credit on Food Catering & Luxury Vehicle Lease

Impact: ₹58,000.00

Detected ₹36,000 ITC on Corporate Catering (Oberoi Events #OB-7712) and ₹22,000 on Passenger Vehicle Lease (Elite Rentals #CR-1044). Claiming this violates Section 17(5)(a) & (b)(i). Must be reversed in Table 4(B)(1).

💡 AI Recommendation: Auto-route ₹58,000 to GSTR-3B Table 4(B)(1) Ineligible Reversals to prevent notice under Sec 73/74.

HIGH SEVERITY TAX TYPE / POS ERROR Place of Supply Error: IGST Charged on Intra-State Supply

Impact: ₹45,000.00

Supplier Apex Tech Solutions (GSTIN: 27AAACA1234A1Z1) is in Maharashtra (State 27 — same as client), but charged ₹45,000 IGST instead of CGST (₹22,500) + SGST (₹22,500). Ineligible for intra-state ITC claim without amendment.

💡 AI Recommendation: Request supplier credit note & adjust tax head in client books before GSTR-3B offset.

HIGH SEVERITY SECTION 16(2)(aa) RISK Supplier Unfiled GSTR-1: ₹64,000 ITC Missing in GSTR-2B

Impact: ₹64,000.00

Skyline Logistics (GSTIN: 06BBBCB9876B1Z2) Invoice #SK-4491 (₹64,000 ITC) was booked in Purchase Register but does not appear in auto-drafted GSTR-2B. Claiming this will trigger automated GSTN mismatch notice.

💡 AI Recommendation: Defer ₹64,000 ITC claim to next month and auto-dispatch WhatsApp filing reminder to Skyline Logistics.

HIGH SEVERITY DUPLICATE ENTRY Duplicate Purchase Invoice #APX-204 in Client Books

Impact: ₹18,500.00

Invoice APX-204 from Apex Tech Solutions was booked twice in Tally/Zoho ledger, falsely inflating ITC claims by ₹18,500.

💡 AI Recommendation: Purge duplicate entry from ledger to ensure accurate GSTR-3B computation.
