Question 1

What is the process for e-invoice setup?

Accepted Answer

The process runs in clear stages: Applicability check; IRP registration; Software configuration; Testing and training. A senior consultant reviews your file at each stage rather than passing it to a data-entry desk, and you receive a confirmation with the filed documents once it is complete. You always know which stage your work is at — we update you on WhatsApp instead of leaving you to follow up.

Question 2

Are there any hidden charges for e-invoice setup?

Accepted Answer

No. The fee quoted before we start is the fee you pay. Government fees, portal charges or statutory late fees, where they apply, are separate and disclosed to you in advance with the exact amount. We issue a proper GST invoice for our professional fee. If the scope of work changes — for example, an unexpected notice or additional periods — we tell you the revised fee before doing anything further.

Question 3

Do I need to generate e-invoices for my retail B2C sales too?

Accepted Answer

No. The e-invoice mandate covers B2B supplies, supplies to SEZs, exports and credit or debit notes for such transactions. B2C invoices are not reported to the IRP at present. However, taxpayers with aggregate turnover above Rs.500 crore must print a dynamic QR code on B2C invoices to enable digital payment, which is a separate requirement from e-invoicing. So a retailer in Madipakkam with Rs.8 crore turnover generates IRNs only for its B2B and export invoices while billing walk-in customers normally. Configuring your billing software to segregate the two flows avoids accidental non-compliance.

Question 4

How do I register on the Invoice Registration Portal and set up e-invoicing?

Accepted Answer

Registration is done on the e-invoice portal einvoice1.gst.gov.in using your GSTIN; the system verifies you through an OTP sent to your GST-registered mobile and email, after which you create IRP login credentials. Businesses already registered on the e-way bill portal can use the same credentials. You then choose how invoices will be reported: direct portal entry, the free offline utility, or API integration through your accounting software such as Tally or a GSP. ChennaiGST handles the complete setup including software configuration and staff training for businesses in Madipakkam for Rs.1,999; call +91 - 9600 606 444 to schedule it.

Question 5

Can I run different invoice series for different branches or types of sales?

Accepted Answer

Yes. The rules expressly permit one or multiple series of invoice numbers, so you can run separate series for each branch, counter or category, for example RET/001 for retail billing and EXP/001 for exports, under the same GSTIN. Each series must independently be consecutive and unique within the financial year, and all series must be reported in the documents table of GSTR-1. For businesses under the e-invoicing mandate, the IRP validates that a document number is not repeated within the year for the GSTIN, so overlapping series will cause IRN rejections. We help Madipakkam businesses design clean series structures; call +91 - 9600 606 444.

Question 6

Is e-invoicing compulsory for my business, and at what turnover?

Accepted Answer

E-invoicing is mandatory for registered businesses whose aggregate turnover has exceeded Rs.5 crore in any financial year from 2017-18 onwards, for their B2B supplies and exports. The Rs.5 crore limit applies from 1 August 2023. Once you cross the threshold in any year, the mandate applies from the start of the next financial year and continues permanently, even if turnover later falls. Note that turnover is computed PAN-wide across all GSTINs, not branch-wise. If your books show you crossing Rs.5 crore this year, plan the IRP setup in advance rather than scrambling in April.

Question 7

What is the penalty if I am covered by e-invoicing but do not generate IRNs?

Accepted Answer

The consequences are serious. An invoice issued without an IRN by a mandated taxpayer is not a valid tax invoice, which exposes you to penalty under Section 122 of Rs.10,000 or the tax due, whichever is higher, per invoice for non-issuance, and Rs.25,000 per invoice for an incorrect invoice. Goods moving on such invoices can be detained, and, most damaging commercially, your B2B customers may lose their input tax credit and will quickly stop buying from you. Large buyers now routinely verify IRNs before releasing payments. If you have crossed Rs.5 crore and have not started, regularise immediately rather than waiting for a notice.

Question 8

What exactly are the IRN and QR code on an e-invoice?

Accepted Answer

When you report an invoice to the Invoice Registration Portal, it validates the data and returns a unique 64-character Invoice Reference Number, which is a hash generated from your GSTIN, the document number and the financial year, along with a digitally signed QR code. The QR code embeds key details such as both GSTINs, invoice number and date, taxable value and the IRN, allowing anyone to verify the invoice offline. A B2B invoice issued by a mandated taxpayer without an IRN is not a valid tax invoice, and the printed copy must carry the QR code.

Question 9

We hire security guards from an agency. Should they charge GST or should we pay it ourselves?

Accepted Answer

Check the agency's constitution. Since 1 January 2019, security services by way of supply of security personnel provided by any person other than a body corporate to a registered person fall under reverse charge, so your business pays the 18 percent directly and claims credit. If the agency is a body corporate, such as a private limited company, it charges GST under forward charge on its invoice. Recipients registered under the composition scheme are excluded from this reverse charge entry. Businesses in Madipakkam commonly pay agencies' forward-charge invoices while also missing their own RCM cases, so an annual review of security and manpower bills is worthwhile.

Question 10

How is interest calculated if I pay GST late?

Accepted Answer

Interest is charged at 18 percent per annum under Section 50 of the CGST Act, calculated day-wise from the due date until the date of payment. Following the amendment to Section 50, interest on delayed GSTR-3B filing applies only on the portion of tax paid through the electronic cash ledger, not on the amount settled using input tax credit. For example, a cash liability of Rs.1,00,000 paid 30 days late attracts roughly Rs.1,479 as interest. We compute this precisely before filing so clients in Madipakkam never overpay or underpay.

Question 11

What GST rate do medicines attract in my pharmacy after the 2025 rate changes?

Accepted Answer

From 22 September 2025, virtually all drugs and medicines that earlier attracted 12% moved to 5%, and a notified list of thirty-six lifesaving drugs, covering cancer and rare-disease therapies, became nil rated. Most medical devices and diagnostic kits also settled at 5%. For a retail pharmacy, this means the shelf is now dominated by 5% and nil items, so your rate master, purchase entries and reorder pricing all needed revision from that date. Old stock purchased at 12% is sold at the new rate applicable on the date of supply, with your input credit remaining intact. Call +91 - 9600 606 444 for a rate-master review.

Question 12

Our security agency does not charge GST on its bills. Is that correct?

Accepted Answer

Quite possibly, yes. Since 1 January 2019, security services meaning supply of security personnel, when provided by any person other than a body corporate to a registered person, fall under reverse charge, so the agency correctly bills without tax and you pay 18 percent through GSTR-3B in cash, claiming ITC. If your security agency is a private limited company, however, RCM does not apply and it must charge GST on its invoice under forward charge. Composition taxpayers as recipients are excluded from this entry. Confirm the agency's constitution from its PAN, because paying under the wrong mechanism creates trouble for both sides.

Question 13

How do I file Form PMT-09 to move money between heads in my cash ledger?

Accepted Answer

Log in and open Services, then Ledgers, then Electronic Cash Ledger, and select File GST PMT-09 for transfer of amount. The screen shows your balance under each major and minor head. Choose the transfer-from head and amount, choose the transfer-to head, add the details to the table, preview and file with DSC or EVC. The transfer reflects in the ledger immediately and an ARN is generated for your records. There is no limit on how often PMT-09 can be filed, and no government fee applies, so it is always the first fix for a wrong-head deposit.

Question 14

Is GST still charged on health insurance premiums?

Accepted Answer

Not on individual policies. With effect from 22 September 2025, premiums on all individual life insurance policies and individual health insurance policies, including family floater and senior citizen plans, are exempt from GST, along with their reinsurance. Earlier these attracted 18 percent, so the change directly reduces the premium outgo for households. Group policies taken by businesses for employees continue to be taxable, and the input tax credit position on such group covers still depends on whether the cover is statutorily obligatory. When renewing policies, check that the insurer has passed on the exemption rather than merely repricing the premium.

Question 15

How does GST work on lorry freight paid to a goods transport agency?

Accepted Answer

A goods transport agency, identified by its issue of a consignment note, is taxed in one of two ways. By default, specified recipients such as companies and registered persons pay 5 percent under reverse charge on the freight and can claim it as ITC. Alternatively, the GTA may opt to pay tax itself under forward charge, at 5 percent without ITC or 18 percent with ITC after the September 2025 rate rationalisation replaced the earlier 12 percent option, by filing the prescribed declaration for the financial year; the invoice should state this option. Transport by an individual lorry owner without a consignment note is not a GTA service and is exempt. Check each transporter's invoice wording before deciding who pays the tax.

Question 16

Is there really a penalty for not displaying my GST number at my shop?

Accepted Answer

Yes. Rule 18 of the CGST Rules requires every registered person to display the registration certificate in a prominent location at the principal place of business and every additional place, and to display the GSTIN on the name board at the entry of each such premises. There is no separate penalty provision for this lapse, so officers invoke the general penalty under Section 125, which can extend to Rs.25,000 under CGST with a matching state penalty. Inspection teams visiting Madipakkam markets routinely check name boards first, so a few hundred rupees of signage is the cheapest compliance in the entire GST law.

Question 17

Are hospital and clinic charges exempt from GST?

Accepted Answer

Healthcare services provided by a clinical establishment, an authorised medical practitioner or paramedics are exempt from GST. This covers diagnosis, treatment and care for illness, injury, deformity or pregnancy in any recognised system of medicine in India, and includes transportation of patients by ambulance, which is separately exempt for any provider. Consultation fees, surgery charges, nursing and diagnostic services within this definition carry no GST, which is why hospitals do not charge tax on treatment bills. The exemption attaches to the nature of the service, not the size of the hospital, so both a large corporate hospital and a single-doctor clinic are covered.

Question 18

How do I round off tax amounts on a GST invoice?

Accepted Answer

Section 170 of the CGST Act prescribes normal rounding to the nearest rupee: where the tax contains a part of a rupee, fifty paise or more is rounded up to one rupee, and less than fifty paise is ignored. The rounding is applied to the tax amount on each invoice, separately for each tax head, so CGST and SGST are each rounded individually rather than rounding only the invoice total. Most billing software handles this automatically, but spreadsheets and manual bills often round the grand total instead, creating one-rupee mismatches that clutter reconciliations across thousands of invoices.

Question 19

How long does e-invoice setup take in Madipakkam?

Accepted Answer

1-2 working days. That assumes your documents are complete and there is no departmental query. We start the same day we receive your papers and tell you the realistic completion date upfront rather than an optimistic one. Where the GST portal or the officer causes delay — clarifications, physical verification or system issues — we track it daily and keep you informed on WhatsApp.

Question 20

Do you provide e invoice registration for small businesses and proprietorships in Madipakkam?

Accepted Answer

Yes. A large share of our clients in Madipakkam are proprietors, small traders, shop owners, freelancers and family businesses rather than large companies. The fee of Rs.1,999 and the process are the same regardless of size, and we explain the compliance position in plain language — in Tamil or English — so you understand what is being filed on your behalf and why.

Question 21

Can I get e-invoice setup done online without visiting the office?

Accepted Answer

Yes, the entire process can be handled online. You share scanned documents on WhatsApp or email, we prepare and file everything on the GST portal, and you receive the acknowledgement and filed copies digitally. Businesses in Madipakkam regularly complete e-invoice setup with us without a single office visit. If a physical verification or personal hearing is required by the department, we guide you through it.

Aspect	With ChennaiGST	DIY / Unattended
Time cost	Roughly an hour a month to send data and approve drafts; the portal work, reconciliation and follow-up are ours.	Hours every month lost to portal errors, JSON files, OTP failures and reworking figures — usually on the due date itself.
Supplier defaults	Suppliers who stop uploading invoices are identified within the period and pursued before their default becomes your blocked credit.	Missing supplier invoices surface only when credit is denied, by which time recovering the amount from the vendor is difficult.
Goods in transit	E-way bills generated correctly and matched to invoices, so consignments pass roadside inspections without detention or penalty.	A defective or missing e-way bill can mean detention at a checkpoint, with penalties that dwarf the tax on the consignment.
Input tax credit	Purchase register matched against GSTR-2B each period, with defaulting suppliers chased so eligible credit is actually captured.	Credit claimed from books alone; mismatches with GSTR-2B mean lost credit or excess claims that invite departmental queries.
Registration and amendments	Query-resistant applications prepared correctly the first time, with supporting documents matched to what proper officers actually verify.	Repeated clarification memos and resubmissions, with weeks lost because a rent agreement or premises photograph did not meet expectations.
Risk of notices	GSTR-1, GSTR-3B and GSTR-2B reconciled before filing, removing the mismatches that trigger most scrutiny notices.	Inconsistent figures across returns quietly build a mismatch history that surfaces later as ASMT-10 scrutiny or a demand notice.
