Trap 01The taxable value column is not called Taxable ValueIt is called "Taxable Value (Final Invoice Amount -Taxes)", parenthesis and all. A reader that looks for the obvious name finds nothing, and builds a return with the right tax on no sales at all.
What fynxIQ doesReads the column under the name the real export gives it, taken from a real November 2025 file rather than from the published column list.
Trap 02One order item can carry two invoicesOrder Item ID repeats across documents in the real file. Treat it as the identity of a sale and two genuinely different sales collapse into one.
What fynxIQ doesKeys every line on its document number. The order item is kept only as where the line came from.
Trap 03A "Cancellation" can still be a credit noteRows reading Event Type Return and Event Sub Type Cancellation are ones Flipkart raised a credit note for, and nets off in its own GSTR-1 sheet. Excluding them like a true cancellation overstates the month.
What fynxIQ doesLets the Event Type alone decide, so those rows are filed as sales returns with their credit notes. True cancellations are left out and counted.
Trap 04The cash-back sheet is part of your sales after allWhen a bank funds part of a promotion, the buyer’s invoice shows the price after the offer and Flipkart raises a credit note to you for the bank’s share, at the product’s own rate, against the order item. That share is consideration for the sale paid by someone other than the buyer, so it is taxable value (CGST Act s.2(31), s.15(2)(e)), and Flipkart declares the sale at the full price in its own GSTR-1 sheet and in its GSTR-8.
What fynxIQ doesAdds the note to the sale it names and says so. On a real December that was 5.83, and it was the only thing between the two documents. A note that names no single sale in the file is left out and listed rather than put against a sale it may not belong to.
Trap 05The GST report on its own gives totals, not invoicesThe report is Flipkart’s summary: totals by state, totals by HSN code, and an invoice series, and nowhere which state bought which code. Five real months, February to June 2026, came with this report and no Sales Report, beside Amazon’s, Meesho’s and Myntra’s order files.599.02 in the report, 599.02 in the return
What fynxIQ doesTakes its totals as Flipkart’s part of the return: B2CS state by state and Table 12 code by code as Flipkart states them, its invoices in Table 13 and Flipkart in Table 14, and says that none of it is checked against an invoice. On a real February that was 599.02 against the portal’s 602.00, a rupee a state of rounding.
Trap 06A code sold and returned in one month prints as a row of nothingSection 12 then shows the gross value, a quantity of 0, nothing taxable and no tax. The sheet has no rate column, and there is no rate to work back from nothing.
What fynxIQ doesPasses over the row, as it does a state that nets to nothing, instead of stopping the return for a rate Table 12 does not need.
