FAQ

For a QRMP taxpayer, what does a monthly service still do for me, and do I need IFF each month

Under QRMP, you file GSTR 3B quarterly, yet monthly services remain vital, they cover TDS payments, reconciliations, e invoice checks, vendor nudges, and optional IFF for the first two months if you want customers to claim ITC earlier. A provider like AI Accountant will keep the monthly discipline so the quarter end filing is accurate and cash neutral.

What SLAs should I sign to ensure filings are never late, especially around the seventh, the eleventh, and the twentieth windows

Lock SLAs for, data intake by day five, TDS challan prepared and paid by the seventh, GSTR 1 prepared by day ten and filed by the eleventh, GSTR 2B reconciliation by day sixteen, and GSTR 3B computation, challan, and filing by your due date. Include a defined escalation path and a maker checker review.

What is an acceptable monthly ITC mismatch, and how do you measure reconciliation quality

Mature teams target a ninety five percent plus monthly ITC match to GSTR 2B. Quality is measured by, unresolved vendor mismatches, age of mismatches, and the cash impact from blocked ITC. AI Accountant tracks these as dashboard KPIs and issues vendor wise nudges with evidence trails.

We operate multiple GSTINs across states, can a virtual provider centralize control and still file locally

Yes, a CA led virtual provider can run entity wise reconciliations and filings while giving you a consolidated dashboard. Expect a unified task board, entity switches, and a shared document repository with GSTIN level segregation for audits.

How are GST and Income Tax portal credentials secured, and how do you handle OTPs without compromising control

Best practice is role based access, vault storage for credentials, and controlled OTP workflows. OTPs are either routed to a shared number under your control or relayed through an approved authenticator. AI Accountant uses maker checker for filings and logs OTP handoffs for audit trails.

Vendors do not upload on time, how do you protect working capital when 2B does not reflect credits

Use a strict vendor scorecard, monthly nudges with invoice evidence, and a cut off rule for provisional booking versus claim deferral. AI Accountant flags high value misses early, assists with vendor outreach, and simulates cash impact so you can time payments prudently.

How does an AI enabled service integrate with Tally, Zoho Books, QuickBooks, and bank feeds without breaking our current setup

Integration is non intrusive, typically via connectors or scheduled exports. Expect nightly syncs of masters and vouchers, daily bank statement pulls, and reconciliation reports posted back to your books. AI Accountant supports API or file based flows, whichever your tool stack allows.

Which TDS sections cause the most leakage, and what controls stop short deduction interest

Common trouble areas are 194C versus 194J classification, 194H for commissions, and 194Q on purchase of goods. Controls include vendor onboarding with section mapping, threshold trackers, and a pre payment TDS check. A monthly exception report reduces surprises at quarter end.

We have a backlog of missed months, what is a realistic timeline to regularize and handle notices

With full data access, one to two weeks per quarter is common for backfill, depending on volume and gaps in vendor data. AI Accountant sequences filings to minimize interest and late fees, submits clarifications, and compiles annexures for any open notices.

How are retainers structured, what are typical inclusions, and where do hidden costs creep in

Retainers scale with invoice counts, number of GSTINs, and modules like payroll TDS or ROC support. Inclusions usually cover monthly GST, TDS challans, reconciliations, and a standard notice response. Extra costs can arise from extensive past period cleanups, special audits, or high volume notice management, agree these up front.

How do you demonstrate audit readiness for lenders or investors during diligence

Provide a monthly compliance pack, challans, acknowledgments, ITC match reports, TDS registers, and bank reconciliations with sign offs. AI Accountant keeps these indexed by month so you can share a single link or folder for diligence with minimal prep time.

Can you manage payroll TDS, professional tax, PF, and ESI alongside GST and vendor TDS

Yes, monthly services commonly include payroll TDS, PT, PF, and ESI reminders and challans. The advantage is one calendar and one dashboard, so finance tracks all statutory outflows in a single view and avoids cut off slips.

What governance cadence should a CFO expect, weekly standups or only month end reviews

Run a light weekly check for data intake and exceptions, then a structured month end review of filings, reconciliations, and cash impact. AI Accountant offers both, a weekly pulse and a month close review with actions and owners.

How does March year end change the monthly routine, especially for TDS and GST

March compresses timelines, TDS deposits run to the thirty first, volume spikes, and annual adjustments often hit. Plan earlier data cut offs, extra reviews of ITC eligibility, and a locked calendar for filings and challans. A provider should add interim checkpoints in the last fortnight of March.

If we self file nil returns some months, is a managed service still useful

Yes, even in nil months you benefit from reconciliations, vendor follow ups, and alerts, so there is no surprise when activity resumes. AI Accountant keeps the ledger tidy, validates portal statuses, and ensures that the next active month starts clean.
