A practical prep checklist for Amazon, Flipkart and Meesho sellers ahead of the 2026 festive sale season — inventory financing, GST invoicing at scale, and platform deadlines.

Step 1: Pull last year's festive sales data (or a conservative proxy)

Export your Amazon, Flipkart and Meesho order history for last year's festive window (or, if you're newer, use your best month's sales as a conservative baseline). Identify your top 15-20 SKUs by festive-period revenue — these are what you'll plan inventory and cash flow around.

Step 2: Forecast festive demand per hero SKU

For each hero SKU, estimate expected festive-week units using last year's uplift multiple (or a conservative 2-3x your monthly average if no prior data exists). Build in a buffer above the forecast for your top sellers so a demand spike doesn't stock you out mid-sale.

Step 3: Calculate the total landed cost of your festive stock

Add up procurement cost, GST paid on inputs, freight, and any packaging or labelling changes needed for the sale, across all hero SKUs. This is your total inventory outlay for the season, before financing.

Step 4: Size the working capital gap and arrange financing early

Subtract what you can fund from existing cash flow and receivables from the total landed cost. Use a working capital loan calculator to model EMI or repayment terms against your expected festive-period cash inflows, and apply at least 3-4 weeks before the sale start date — lender disbursal and platform inventory deadlines both compress in September.

Step 5: Stress-test festive pricing against margins, not just revenue

For every SKU you plan to discount, run the discounted price through a marketplace profit calculator including commission, referral fees, shipping, and any platform-funded discount clawback. Drop or reprice SKUs that go margin-negative at your planned discount depth.

Step 6: Confirm each platform's seller deadlines on your dashboard

Log in to Amazon Seller Central, Flipkart Seller Hub, and Meesho Supplier Panel separately and note each platform's cutoff dates for inventory commitment, pricing lock, deal/coupon submission, and FBA or fulfilment-center stock-in windows for the festive event. These deadlines are platform- and category-specific — don't assume they match across marketplaces.

Step 7: Set up GST invoicing for high-volume days

Confirm your billing software (or marketplace-integrated invoicing) can handle your expected peak daily order volume without manual intervention. Keep an offline invoicing fallback ready, and pre-check your GSTIN, HSN codes, and tax rates are correctly mapped for every SKU going into the sale so invoices generate without errors at scale.

Step 8: Plan for GST payment and ITC timing around the sale spike

A festive sales spike means a spike in output tax liability in that month's GSTR-3B. Set aside the estimated GST outflow separately from operating cash so a strong sales month doesn't leave you cash-short when the return is due, and reconcile input tax credit on festive-related purchases (freight, packaging, ad spend) before filing.

Step 9: Prep returns and customer service capacity

Festive sale volumes bring a proportional rise in returns, cancellations and customer queries in the following 2-3 weeks. Confirm your reverse logistics capacity and customer support bandwidth can absorb the post-sale volume without delaying refunds, which affects both cash flow and account health ratings.

Step 10: Reconcile settlements and file on time

After the sale window closes, reconcile marketplace settlement reports against your invoices and inventory records promptly. Don't let the reconciliation backlog push into your GST return filing deadline — festive-month GSTR-3B and GSTR-1 due dates don't move just because settlement reports arrive late.

A table-by-table walkthrough of GSTR-9C reconciliation — turnover matching, ITC reconciliation, marketplace TCS checks, and the mismatches that trigger GST scrutiny for e-commerce sellers above ₹5 crore turnover.

Step 1: Pull your audited turnover figure

Take the turnover figure certified in your audited financial statements (P&L account) for the financial year — this is your starting reconciliation base, independent of anything already filed with the GST department.

Step 2: Compare against GSTR-9 Table 5 turnover

Match your audited turnover against the outward supply turnover declared across your 12 months of GSTR-1/GSTR-3B and summarised in GSTR-9. List every difference — don't net them against each other — since Table 5 requires each adjustment category shown separately.

Step 3: Identify and categorise each turnover difference

Sort each gap into a known category — unbilled revenue at year-end, advances received but not invoiced, credit notes issued after March 31, non-GST income included in audited turnover (interest, capital gains), or deemed supplies under Schedule I. Undocumented gaps are what draw scrutiny, not the gaps themselves.

Step 4: Reconcile tax paid — books vs. returns

Compare tax payable as computed from your books against tax actually paid across the year through cash and ITC. Flag any shortfall for payment before filing — GSTR-9C requires unpaid differences to be settled, not just disclosed.

Step 5: Reconcile ITC — books vs. GSTR-3B claims (Table 12/14)

Compare ITC as recorded in your audited books against ITC actually claimed across your GSTR-3B filings for the year. Differences usually trace back to timing — credit booked in one month but claimed in another once the invoice appeared in GSTR-2B — or to genuinely unclaimed eligible credit.

Step 6: Reconcile marketplace TCS credit

Cross-check TCS deducted by each marketplace (Amazon, Flipkart, Meesho) under Section 52 against the credit reflected in your electronic cash ledger, the marketplace's annual TCS statement, and Form 26AS/AIS. Resolve any gap from disputed or unprocessed returns before filing.

Step 7: Document and explain every unreconciled difference

For each remaining gap in turnover, tax paid, or ITC, write a specific reason in the relevant GSTR-9C table — "timing difference: March invoice raised in April" is acceptable; leaving a gap unexplained is what invites a scrutiny notice.

Step 8: Get CA/Cost Accountant sign-off and file

Confirm the current year's certification requirement, get the reconciliation statement certified accordingly, and file GSTR-9C alongside GSTR-9 before the due date — filing a reasonably reconciled return on time is safer than a perfect one filed late.

Every marketplace claims the largest reach and the lowest fees. Here's what Amazon, Flipkart, and Meesho actually charge, what GST and TCS obligations each one triggers, and how to pick without guessing.

Amazon, Flipkart, or Meesho: Which E-commerce Platform Actually Fits Your Business

Once your turnover crosses ₹5 crore even one year, e-invoicing stays mandatory forever — and if you're above ₹10 crore, you now have only 30 days to report an invoice to the IRP. Here's what e-commerce sellers need to know.

Step 1: Check whether you've ever crossed ₹5 crore AATO

Look back at every financial year since FY 2017-18. If your aggregate annual turnover crossed ₹5 crore in even one of those years, e-invoicing is mandatory for you now, regardless of your current-year turnover.

Step 2: Confirm which of your supplies need e-invoicing

E-invoicing applies to B2B supplies (and certain notified categories like exports). Pure B2C retail sales are generally outside scope. If you sell both B2B and B2C, separate your invoice workflows so B2B documents route through IRN generation.

Step 3: Set up IRN generation in your invoicing workflow

Connect your billing or GST software to the Invoice Registration Portal (IRP), either directly or via a GST Suvidha Provider (GSP). Every eligible invoice needs to be reported to get a valid IRN and QR code before it's treated as a valid tax invoice.

Step 4: Check if the 30-day rule applies to you

If your AATO is ₹10 crore or more, every invoice, credit note, and debit note must be reported to the IRP within 30 days of its document date. Below ₹10 crore, this specific time limit doesn't apply, though best practice is still to report promptly.

Step 5: Build reporting into your daily or weekly routine

Don't let e-invoice reporting pile up. For sellers above ₹10 crore especially, a backlog that crosses 30 days means those documents can never be reported — treat reporting cadence as a hard operational rule, not a monthly clean-up task.

Step 6: Reconcile IRN-reported invoices with your GST returns

E-invoice data auto-populates into GSTR-1. Reconcile this against your own sales register monthly so mismatches get caught before they become return-filing problems.

E-Invoicing Rules for E-commerce Sellers: ₹5 Crore Limit & 30-Day Rule

CBIC's risk-based provisional refund lets low-risk exporters and sellers get 90% of their GST refund in days instead of months. Here's the eligibility criteria and how to qualify.

Step 1: Build a clean 12-month filing record

File GSTR-1 and GSTR-3B on time every month. The system's risk evaluation weighs consistent, on-time compliance heavily — gaps or repeated late filings work against a low-risk flag.

Step 2: File your refund application (FORM GST RFD-01)

Submit your refund claim through the GST portal with accurate supporting documents — shipping bills, invoices, and bank realisation certificates for export claims.

Step 3: Confirm acknowledgment (FORM GST RFD-02)

Once your application passes basic completeness checks, the system issues an acknowledgment. This is the trigger point for the risk-based provisional sanction process.

Step 4: Let the system risk-assess your claim

GSTN evaluates the claim against risk parameters built from your compliance history. Low-risk claims are eligible for the 90% provisional sanction without waiting for full scrutiny.

Step 5: Receive the 90% provisional amount

If sanctioned provisionally, 90% of your claimed refund is credited, typically much faster than the traditional 60–90 day full-scrutiny cycle.

Step 6: Track the final 10% after verification

The remaining 10% is released once the officer completes final verification of the claim. Keep your documentation ready in case of queries during this stage.

GST's New 90% Provisional Refund: How It Works for E-commerce Sellers

Can an Amazon or Flipkart seller use Section 44AD presumptive taxation and skip detailed books of accounts? Here's the eligibility, the 6%/8% rates, and how it interacts with mandatory GST registration.

Step 1: Confirm your business is 'eligible business' under 44AD

Section 44AD covers most trading and manufacturing businesses, including online selling of physical goods. It excludes specified professions (covered under 44ADA), businesses earning commission or brokerage, and a few other categories — check the exclusion list before assuming eligibility.

Step 2: Check your turnover against the limit

Confirm your financial year turnover is within ₹2 crore, or ₹3 crore if cash receipts stay under 5% of total turnover. Most marketplace sellers accepting online payouts easily meet the 5% cash-receipt condition.

Step 3: Decide between the 6% and 8% rates

If your marketplace payouts and customer payments come through digital channels (bank transfer, UPI, cards) — which is standard for Amazon, Flipkart, Meesho sellers — you declare 6% of that turnover as profit rather than 8%.

Step 4: Compute presumptive income and compare with actual profit

Calculate 6%/8% of turnover as your presumptive taxable profit. If your real profit margin is comfortably above this, 44AD saves you both tax computation effort and the cost of an audit. If your real margin is thin or negative, weigh whether opting out and maintaining full books makes more financial sense.

Step 5: File ITR-4 (Sugam) if you opt for 44AD

Taxpayers using presumptive taxation under 44AD typically file ITR-4, which is simpler than ITR-3 (used when maintaining regular books).

Step 6: Remember the 5-year lock-out if you opt out later

If you stop using 44AD in a future year despite remaining eligible, you cannot go back to it for the next 5 assessment years. Treat the decision to opt in or out as a multi-year one, not a year-by-year convenience choice.

Section 44AD for Online Sellers: Presumptive Taxation Explained

A new CBIC rule lets low-risk e-commerce sellers get GST registration approved in 3 working days through Aadhaar authentication. Here's who qualifies and how to apply.

Step 1: Check your monthly B2B tax liability

Estimate your monthly output tax liability on B2B supplies. Rule 14A's fast-track applies only if it stays within ₹2.5 lakh a month — most small and early-stage e-commerce sellers fall well under this.

Step 2: Gather your Aadhaar and business documents

Keep your Aadhaar number linked to a working mobile number, PAN, business address proof, and bank account details ready before starting the application on the GST portal.

Step 3: Apply on the GST portal and opt for Aadhaar authentication

Start a fresh GST REG-01 application at gst.gov.in. When prompted, choose Aadhaar-based OTP authentication rather than skipping it — this is what makes you eligible for the 3-day track.

Step 4: Complete OTP verification

Verify the OTP sent to your Aadhaar-linked mobile number. This step is what triggers the system's automated risk assessment.

Step 5: Wait for the system risk check

The GSTN system evaluates your application against risk parameters. Low-risk applications move to automatic approval; flagged applications are diverted to standard processing with possible document review.

Step 6: Receive your GSTIN

If approved under the fast-track, your GSTIN is typically issued within 3 working days. Download your registration certificate from the portal and update it across your marketplace seller accounts.

GSTR-1 and GSTR-3B are both mandatory, both monthly, and cover completely different things. Here's the direct comparison — what each return contains, why mismatches happen, and which one to fix first when they don't match.

GSTR-3B vs GSTR-1: What Every E-commerce Seller Must Know

Your AIS shows the Income Tax Department everything third parties reported about you — TDS, TCS, GST turnover, bank interest, mutual fund trades. Here's how to download it, what to check, and how to fix a mismatch before the July 31 deadline.

Log in to the income tax e-filing portal

Go to incometax.gov.in and log in with your PAN. Under Services, select Annual Information Statement (AIS).

Open the AIS and TIS side by side

Click "AIS" for the detailed transaction-level report, and "TIS" (Taxpayer Information Summary) for the processed, category-wise summary that most pre-fills your ITR.

Check the TDS/TCS section against your marketplace payouts

Match Section 194O TDS entries (Amazon, Flipkart, Meesho) and Section 206C(1H) TCS entries against your own payout records for the financial year.

Check the GST turnover section

Under "Other Information," compare the GST turnover reported by GSTN against your actual GSTR-3B/GSTR-1 filings. Mismatches here are common for sellers who file GST quarterly under QRMP.

Check bank interest, dividends, and securities transactions

Review savings account interest, FD interest, dividend income, and any stock or mutual fund buy/sell transactions reported by your broker or AMC.

Raise feedback on any incorrect entry

Click on the specific entry, select "Optional" feedback, choose the reason (e.g. "Income is not taxable," "Duplicate," "Information is incorrect"), and submit. The reporting entity is notified to correct it.

File your ITR only after reconciliation

Use your reconciled AIS/TIS figures — not just the pre-filled defaults — when declaring income. A declared-vs-AIS mismatch is one of the most common triggers for a scrutiny notice.

Udyam registration gives e-commerce sellers priority lending, lower TDS thresholds, and protection against delayed payments. Full eligibility, process, and benefit breakdown for FY 2026-27.

Check your eligibility

Confirm your business falls under Micro (investment up to ₹2.5 crore, turnover up to ₹10 crore), Small, or Medium classification based on the revised April 2025 limits.

Gather your Aadhaar and PAN

Udyam registration requires the Aadhaar number of the proprietor, managing partner, or karta (for HUF), plus the business PAN and GSTIN if applicable.

Visit the Udyam Registration portal

Go to udyamregistration.gov.in — this is the only official government portal; there is no fee to register.

Fill in business and investment details

Enter business name, type, address, bank account details, and investment/turnover figures — these are auto-verified against your PAN and GST returns where available.

Submit and receive your Udyam Registration Number

On successful submission, you receive a permanent Udyam Registration Number (URN) and an e-certificate immediately — no renewal required.

Learn the exact GST invoice format required for e-commerce sellers in India. Covers mandatory fields, B2B vs B2C rules, and e-invoicing limits for 2026.

Step 1: Get your GSTIN and exact business details

Your invoice must perfectly match your GST registration. Keep your GSTIN, registered legal name, and principal place of business ready.

Step 2: Assign a unique, sequential invoice number

Invoice numbers must be sequential, alphanumeric, and a maximum of 16 characters. Example: INV/26-27/001. Never repeat an invoice number in the same financial year.

Step 3: Find the correct HSN code for your product

Identify the correct HSN code for your item. Use 4 digits if your turnover is under ₹5 crore, and 6 digits if it is above. Check the GST rate associated with that exact code.

Step 4: Separate the tax amount from the product price

Do not just write a flat price. You must show the taxable value (base price) and the tax amount separately. Split the tax into CGST and SGST for intra-state sales, or IGST for inter-state sales.

Step 5: Add the buyer's GSTIN if it is a B2B sale

Ask the buyer if they need Input Tax Credit. If yes, collect their GSTIN and add it to the invoice under 'Billed To'. Without this, they cannot claim the credit.

Step 6: Issue the invoice before or at the time of shipping

Under GST rules for goods, the invoice must be generated before or at the time the product leaves your warehouse. Include a printed copy inside the package or send it electronically.

GST Invoice Format for E-commerce Sellers: Complete Guide (2026)

Selling on Amazon or Flipkart and seeing 1% TCS deducted from every payout? Here's how to claim that money back correctly through GST and income tax without missing credits.

Step 1: Download Amazon and Flipkart settlement reports

Log in to your seller panels and download monthly settlement, transaction, and deduction reports. Keep the period aligned with the month for which you are filing GST so your reconciliation stays clean.

Step 2: Identify the TCS amount deducted

Separate TCS from commissions, shipping charges, ad spend, penalties, and return adjustments. Do not post it as a normal marketplace expense.

Step 3: Match the deduction with your GST records

Compare the marketplace deduction with your taxable turnover and GST working for the same month. If you sell through multiple GSTINs, reconcile GSTIN-wise rather than brand-wise.

Step 4: Use the credit while preparing GSTR-3B

Adjust the matched TCS amount correctly in your GST workflow so the tax already collected through the marketplace reduces your actual cash outflow.

Step 5: Track any leftover balance month by month

If the available balance is more than your immediate liability, carry it forward in a monthly reconciliation sheet. Do not let it sit unnoticed for multiple months.

Step 6: Apply for refund if excess remains eligible

When excess balance remains after proper adjustment and the documentation is clean, file for a refund under the GST process. Keep reports, reconciliations, and return copies ready in case clarification is requested.

How to Claim TCS Refund on Amazon and Flipkart Sales

GSTR-3B is due on the 20th every month. Since January 2026, the portal blocks filing if your ITC claim exceeds GSTR-2B. Here's the complete reconciliation-first workflow, IMS integration, and portal walkthrough for FY 2026-27 — including the ITC claim restriction most sellers don't know about.

Download your GSTR-2B ITC statement

Log in to the GST portal (gst.gov.in) → Returns → Input Tax Credit → GSTR-2B. Download the statement for the current month. This is your maximum allowable ITC — do not claim more than this amount.

Reconcile GSTR-2B against your purchase register

Compare every line in GSTR-2B against your own purchase records. Flag invoices present in GSTR-2B but missing from your register (accept in IMS), and invoices in your register but absent from GSTR-2B (chase supplier to file GSTR-1).

Review IMS and accept or reject supplier invoices

Go to Returns → Invoice Management System (IMS). Accept all valid invoices and reject incorrect ones before the 13th of the month. Actions taken here update your GSTR-2B before it is generated on the 14th.

Open GSTR-3B on the portal

Go to Returns → Returns Dashboard → Select the return period → GSTR-3B → Prepare Online. Do not click Submit before verifying all tables.

Fill Table 3.1 — outward tax liability

Enter your total outward supplies grouped by tax rate (5%, 12%, 18%, 28%). Include reverse charge supplies in 3.1(b). This section declares what you owe in output tax for the month.

Fill Table 4 — ITC claim

Enter eligible ITC from GSTR-2B in Table 4A(5). Do not enter an amount higher than your GSTR-2B figure — the portal will block filing since January 2026. Reverse any ITC on exempt supplies in Table 4B.

Fill Table 5.1 — exempt and nil-rated supplies (if applicable)

If you made any exempt, nil-rated, or non-GST supplies during the month, declare the value here. Most marketplace sellers will enter zero.

Preview, verify net tax liability, and pay

Click Preview to review the auto-computed net tax payable. If the electronic cash ledger balance is insufficient, pay the shortfall via challan (Create Challan → Net Banking / UPI). Tax payment must happen before filing.

File GSTR-3B before the 20th

Click File GSTR-3B → select DSC or EVC → submit. Monthly filers: due by the 20th. QRMP filers: due by the 22nd (Category I states) or 24th (Category II states). You will receive an ARN confirming successful filing.

How to File GSTR-3B: ITC Reconciliation and Step-by-Step Guide (FY 2026-27)

GSTR-1 is due on the 11th of every month. Most marketplace sellers file it wrong — wrong HSN codes, B2B invoices in the wrong table, Amazon TCS missing. Here's the complete portal walkthrough for FY 2026-27, with the 2026 HSN enforcement change and IMS updates included.

Compile all outward supply invoices for the month

Download your sales report from each marketplace (Amazon Seller Central, Flipkart Seller Hub, Meesho Supplier Panel). Separate invoices by buyer type: B2B (buyer has GSTIN) and B2C (individual buyer). This is your source data for GSTR-1.

Log in to the GST portal and open GSTR-1

Go to gst.gov.in → Returns → Returns Dashboard → Select the return period → GSTR-1 → Prepare Online. You can also use Prepare Offline to upload a JSON file if you have many invoices.

Enter B2B invoices in Table 4A

For every invoice issued to a GSTIN-registered buyer, enter the buyer's GSTIN, invoice number, invoice date, taxable value, and tax rate. This data flows directly into your buyer's GSTR-2B — accuracy here protects their ITC.

Enter B2C large invoices in Table 5

For interstate B2C sales above ₹2.5 lakh per invoice, enter each invoice individually in Table 5 with the place of supply (destination state) and tax breakdown.

Enter B2C small supplies in Table 7

All remaining B2C sales (intrastate any value, or interstate under ₹2.5 lakh) are reported as an aggregate summary in Table 7 grouped by state. You do not enter individual invoices here.

Fill HSN Summary in Table 12

Enter your sales grouped by HSN code. Mandatory: 8-digit codes if your annual turnover exceeds ₹5 crore; 4-digit codes if turnover is ₹1.5–5 crore. From 2026, the portal rejects entries with incorrect HSN codes — use the portal's HSN search tool to verify codes before entry.

Preview and verify totals

Click Preview GSTR-1 to download a draft PDF. Verify the total invoice count, taxable value, and tax amount matches your own records. Any discrepancy must be corrected before filing — you cannot edit a filed GSTR-1, only amend it in the next month.

File GSTR-1 before the 11th

Click Submit → File GSTR-1 with DSC or EVC. Monthly filers: due by the 11th of the following month. QRMP quarterly filers: due by the 13th after quarter end. You receive an ARN confirming successful filing.
