Selling goods or services online is no longer limited to one website or one marketplace. Many Indian businesses now sell through Amazon, Flipkart, Meesho, Myntra, Shopify, WooCommerce, social commerce, payment links, international marketplaces, and overseas customers.
But as online sales grow, accounting becomes more complex. A normal sales invoice and bank entry system is not enough for an e-commerce business. Online sellers must track marketplace settlements, payment gateway deductions, GST, TCS, returns, inventory movement, shipping charges, advertising spends, foreign currency receipts, and monthly profitability.
This is where specialised e-commerce accounting becomes important.
A single ₹1,000 sale on a marketplace is never just ₹1,000. By the time it reaches your bank, the platform has carved out a commission, a closing fee, shipping and fulfilment charges, GST on those fees, Tax Collected at Source (TCS) under GST, income-tax TDS under Section 194-O, and sometimes a promotional discount the platform funded. A return reverses some of these but not all. Multiply that across hundreds of orders, two or three marketplaces, a website, and a payment gateway, and “just check the bank statement” stops working very quickly.
Why E-Commerce Accounting Is Different
In traditional accounting, a sale is usually simple: invoice raised, payment received, expense recorded, and tax filed. In e-commerce, one customer order can create multiple accounting entries.
For example, a marketplace sale may include:
- Product selling price
- GST collected
- Marketplace commission
- Shipping fee
- Collection fee
- Fixed closing fee
- Advertising cost
- GST on marketplace charges
- TCS deducted by the marketplace
- Return or cancellation adjustment
- Final payout received in the bank
If these items are not reconciled properly, the seller may show wrong sales, wrong GST liability, wrong profit, or incorrect inventory value.
1. Marketplace Sales Reconciliation
Marketplace sales reconciliation means matching order-wise sales data from platforms such as Amazon, Flipkart, Meesho, Myntra, Ajio, Etsy, eBay or other portals with accounting records.
A seller should reconcile:
- Orders placed
- Orders shipped
- Orders delivered
- Cancelled orders
- Customer returns
- RTO cases
- Marketplace claims
- Refunds issued
- Marketplace commission
- Shipping charges
- GST collected
- TCS deducted
- Final settlement received
The most common mistake online sellers make is recording only the bank payout as sales. This is incorrect because the payout is usually net of marketplace deductions. The gross sale, GST, platform expenses and deductions must be recorded separately.
Correct marketplace reconciliation helps the seller know the real revenue, real expenses and real profit from each platform.
2. Payment Gateway Reconciliation
For sellers using their own website or direct payment links, payment gateway reconciliation is equally important. Payment gateways such as Razorpay, PayU, Cashfree, Instamojo, Stripe, PayPal and others usually deduct charges before transferring money to the seller’s bank account.
For example, if the customer pays ₹10,000, the seller may receive only ₹9,750 after gateway charges and GST on gateway fees.
Payment gateway reconciliation should match:
- Website orders
- Payment success and failure reports
- Refunds
- Chargebacks
- Gateway charges
- GST on gateway charges
- Net bank settlements
- Foreign currency conversion, if applicable
For international sales, reconciliation should also include exchange rate difference, bank charges, platform fees and foreign currency gain or loss.
3. Inventory-Linked Accounting
Inventory is one of the biggest accounting challenges for online sellers. Many sellers sell the same product across multiple platforms, and stock may move through warehouses, fulfilment centres, marketplace fulfilment services or direct dispatch.
Inventory-linked accounting connects every sale, return and purchase to stock movement.
A proper system should track:
- SKU-wise opening stock
- Purchases
- Stock transfers
- Sales
- Returns
- Damaged stock
- Lost stock
- Replacement shipments
- Closing stock
- Cost of goods sold
- Gross margin per SKU
Without inventory-linked accounting, profit reports can be misleading. A seller may show high sales but may not know which products are profitable, which products are slow-moving, and where stock losses are happening.
Good inventory accounting helps answer important questions:
Which marketplace is most profitable?
Which SKU gives the best margin?
Which product has high returns?
How much stock is blocked in warehouses?
What is the correct closing inventory value for monthly books?
4. GST Reports for Online Sellers in India
GST reporting is a key part of e-commerce accounting in India. Online sellers must ensure that their sales, returns, credit notes, input tax credit and marketplace deductions are correctly reflected in monthly GST working.
Important GST reports for e-commerce sellers include:
- Sales register
- B2C sales summary
- B2B sales summary
- Export sales report
- Credit note and return report
- GST output liability report
- Input tax credit report
- GSTR-1 working
- GSTR-3B working
- GSTR-2B reconciliation
- TCS credit reconciliation
- HSN-wise sales summary
- State-wise sales summary
- Marketplace-wise GST summary
Marketplaces may collect TCS under GST and report it through GSTR-8. Sellers should reconcile this TCS with their GST portal records and books. If TCS is not tracked properly, the seller may miss available credits or show mismatch in GST records.
For export sales, GST treatment must be reviewed carefully. Export of goods or services can generally be treated as zero-rated supply, subject to conditions. Sellers dealing with overseas customers should maintain export invoices, shipping documents, foreign inward remittance records, LUT details where applicable, and refund workings if claiming input tax credit refunds.
5. Accounting for Foreign and International Sales
Many Indian e-commerce businesses now sell outside India through international marketplaces, Shopify stores, Etsy, Amazon Global, eBay, digital service platforms or direct websites.
Foreign sales accounting should include:
- Export invoice value
- Currency used for billing
- Exchange rate applied
- Payment gateway or marketplace charges
- Bank conversion charges
- Foreign inward remittance
- GST export classification
- Shipping and customs cost
- Refunds and chargebacks
- Foreign exchange gain or loss
For service providers selling digital services, consulting, design, marketing, software, courses or subscriptions to foreign clients, accounting should clearly separate domestic sales from export of services.
Foreign sales should not be treated like normal domestic sales without review. The seller must check GST, FEMA, bank realization, export documentation and income tax reporting requirements.
6. Monthly Books for Online Sellers
Monthly bookkeeping is essential for e-commerce sellers because marketplace reports change frequently and payouts may relate to sales from different periods.
A good monthly closing process should include:
- Importing sales data from all marketplaces
- Reconciling payment gateway settlements
- Matching bank receipts
- Booking marketplace fees and GST
- Recording advertising expenses
- Updating inventory and cost of goods sold
- Reconciling GST output and input
- Reconciling TCS credit
- Recording refunds, returns and credit notes
- Booking foreign exchange gain or loss
- Preparing monthly profit and loss
- Reviewing balance sheet items
Monthly books help sellers make better decisions. Instead of waiting until year-end, the seller can understand profit, tax liability, cash flow and stock position every month.
7. Common Accounting Mistakes by E-Commerce Sellers
Many online sellers face tax notices, GST mismatches or profit confusion because of avoidable accounting mistakes.
Common mistakes include:
- Recording net payout as sales
- Ignoring marketplace commission and charges
- Not reconciling TCS credit
- Not recording returns and credit notes properly
- Not matching GSTR-1, GSTR-3B and books
- Not reconciling payment gateway reports with bank
- Not maintaining SKU-wise inventory
- Not tracking foreign currency gain or loss
- Mixing personal and business expenses
- Not closing books monthly
- Not separating domestic and export sales
These mistakes can lead to wrong GST filings, overstated or understated revenue, incorrect profit calculation and poor business decisions.

Indian sellers who sell goods or services online need accurate marketplace sales reconciliation, payment gateway reconciliation, inventory-linked accounting, GST reports and monthly books. Sellers dealing with foreign customers or international platforms also need proper export and foreign currency accounting.
A strong accounting system helps online businesses reduce errors, stay compliant, understand profitability and grow with confidence.
