Why Amazon MTR Reports Are Challenging
Amazon MTR reports contain thousands of transactional event lines, including item prices, shipping charges, promotional discounts, customer refunds, and multi-state warehouse dispatches. Manually segregating B2B wholesale invoices with customer GSTINs from consumer retail B2CS supplies takes hours of manual Excel work.
The GSTWali Solution: GSTWali parses your raw MTR file, calculates tax-exclusive net bases, correctly handles intra-state vs. inter-state Place of Supply (POS) rules, routes B2B transactions to Table 4, and builds schema-compliant JSON in seconds.
Amazon Tables in GSTR-1
