A 16-point GST compliance check that catches errors before the portal or the marketplace rejects them. Fix them in minutes, not next month's amendment. Seven tools, free to run. The two boxes just below tell you which one is yours — and what you need to have ready. Which side of the invoice are you on? InvoiceCheck reads an invoice and tells you what is wrong with it before somebody else does — the GST portal, a marketplace, or a customer who has stopped paying. Two situations, two sets of tools. Catch it before the portal does Wrong tax head, a short HSN code, arithmetic that does not reconcile — the portal rejects the whole return and you find out at filing time. This finds them first, and every flag cites the section it comes from. One invoice in front of you, or a CSV export from Tally, Zoho, Busy or the GSTR-1 offline tool. Check one invoice — Sixteen statutory checks, each citing its section Check a whole batch — A CSV from Tally, Zoho or Busy — worst first Late return calculator — What a missed GSTR-1 or 3B costs GSTR-1 error codes — Every rejection code, and what triggers it Invoice number check — Sixteen characters and the Rule 46(b) limits Check what arrives, chase what does not A supplier's mistake costs you the input tax credit, and a customer who pays late owes you statutory interest whether they know it or not. Both are things you can check in under a minute. The invoice you were given, or the date and amount of one that has not been paid. Verify an invoice — Whether one you were given is genuine Check vendor invoices — Before you claim input tax credit Interest on a late payment — What a buyer owes under the MSMED Act Everything above runs free and without an account. ₹99 unlocks the fixes on a single invoice check — the corrected values and how to put each one right. A wrong tax head is never just a typo One incorrect field holds up a settlement, costs your buyer their input tax credit, and compounds into a late-filing fee. Here is the exposure a single bad invoice carries. Typical Payout at Risk A single held marketplace settlement Typical Hold Duration How long a rejected invoice delays payment Interest on Short Payment Section 50, running from the due date Late Filing Fee Section 47, until GSTR-1 is filed Your proactive defense against compliance risks Identify and resolve invoice discrepancies instantly, long before they reach your buyers or the government.

Transforming statutory risks into guaranteed compliance Indian GST laws impose heavy penalties for minor discrepancies. We insulate your business from these critical vulnerabilities. Input Tax Credit Denial If your supplier's GSTIN is invalid or returns are not filed, the buyer loses Input Tax Credit. This means you pay tax twice — once to your supplier, and again to the government. Late Filing Penalty GSTR-1 filed late attracts ₹50/day (₹20/day for NIL returns). A single month's delay on an incorrect invoice can cost thousands in compounding penalties. Marketplace Payment Holds Amazon, Flipkart, and Meesho automatically reject invoices with wrong tax types (IGST vs CGST/SGST), invalid HSN codes, or calculation mismatches — holding your payments for weeks.
