Honest Take — Module 2: GST — Registration, Returns, Exports, LUT #

This is the module where the rhythm of being a real business hits you. Until now, your OPC was a quiet entity with a CIN. After this module, it has a monthly heartbeat — GSTR-1 by the 11th, GSTR-3B by the 20th, GSTR-2B reconciliation against your purchase register, an LUT filed annually before the first export invoice of the financial year. The cadence is unforgiving in a way that the rest of this path is not. Income tax is quarterly, ROC is annual; GST is monthly. There is no "I'll catch up next month" without compounding penalty. Most engineers I have known about miss their first GSTR-3B deadline because they did not believe the deadline was real until the late fee appeared. You will believe it after the first one. The honest move is to believe it before.

Here is the contrarian recommendation, and you will probably ignore it for the first three months and then come back to it. Run one full GSTR-1 / GSTR-3B / GSTR-2B cycle yourself, with your CA watching, before you delegate it. Not so that you become the person filing returns forever — you should not be. So that you can read what your CA is filing on your behalf. The forms are not friendly, but they are knowable. A founder who has never read their own GSTR-3B is a founder who cannot catch a CA's mistake; a founder who has read three of them in a row can catch the mistake on the fourth. The cost of doing this exercise once is one painful Saturday. The benefit is years of being a competent client.

A truth the formal curriculum cannot say plainly: the LUT (Letter of Undertaking) flow for export of services is fiddly in a way that wastes founder time disproportionately. You file once a year, on the GST portal, before your first export invoice of the financial year. If you file it on time, your USD invoices to US/EU clients are zero-rated and clean. If you forget, your first export invoice is technically supposed to be charged IGST, which the foreign client will refuse to pay (rightly), which will make the invoice limp, which will eventually require a reversal entry that your CA will sigh about. The whole problem is preventable with one form filed once a year. The catch is that nobody reminds you, and the GST portal does not surface it as a deadline. You have to know it exists. That is the actual lesson of this module — Indian compliance is full of these "you have to know it exists" gotchas, and the LUT is the most expensive one for a software exporter.

About the GSTR-2B reconciliation: this is the part that maps cleanly to the engineer brain. Every month, the GST portal generates a GSTR-2B for you — a system-of-record list of input tax credits you can claim, derived from what your suppliers reported in their GSTR-1. Your job is to reconcile that against your purchase register. Mismatches mean either your supplier didn't file correctly or your records are wrong. This is event-sourcing reconciliation. It is also the discipline that, if you let it slip for three months, becomes nearly impossible to recover without a CA charging you 5x. Treat it like Sentry alerts — review monthly, resolve same-day, do not let the queue grow.

About your studio specifically — you will likely have a multi-rail income mix in 12 months: domestic consulting in INR, products in INR, consulting in USD (US clients, zero-rated under LUT), SaaS in USD (subscription clients, also zero-rated under LUT). Each rail is GST-treated differently and needs to be tagged correctly in your books, on your invoices, and on your returns. Setting this up cleanly in month one is straightforward. Setting it up after twelve months of mixed transactions is a forensic exercise. Do it now. Specifically: your invoice template needs separate templates for IGST domestic (B2B, 18%), CGST+SGST domestic (intra-state B2B, 9%+9%), and zero-rated export (LUT-backed, 0%, with the LUT number on the invoice). Three templates. Build them once. Use them forever.

I want to be honest about the emotional shape of this module. You will resent the monthly cadence for the first three months. The resentment will be specific — it will arrive on the 18th of the second month when you realize the 20th is two days away and your CA is asking for invoice copies and you have a client deliverable due Friday. The resentment is fine. By the fourth month it will fade because the cadence will have become a habit, and the habit will have become invisible. By the sixth month you will be slightly surprised at how much of the GST burden has dissolved into routine. The discipline of months 1-3 is what makes month 6 onward easy. There is no shortcut to that internalization other than living through the monthly cadence three times.

There is a secondary effect of the monthly cadence that is worth naming because it is genuinely positive. Once your GST returns are filed cleanly every month, you have real-time financial visibility into your business that most founders don't get until year-end. You know your monthly turnover. You know your tax-deductible expenses. You know your effective margin. This data was always there in your books, but the GST cadence forces you to look at it on a monthly schedule. For an engineer who likes data, this is a quiet bonus the curriculum doesn't fully sell. The compliance was the forcing function; the visibility is the prize. After six months, you will check your monthly P&L the way you check a dashboard, not the way you do a chore.

About the QRMP (Quarterly Returns Monthly Payment) scheme specifically, since it will tempt you. QRMP applies to taxpayers with turnover under ₹5 crore and lets you file GSTR-1 quarterly while paying tax monthly via PMT-06. The marketing pitch is "less paperwork." The actual operational change is small — you still pay tax monthly, you still need to maintain monthly records, the only thing that changes is the GSTR-1 cadence (quarterly) and even then most CAs file IFF (Invoice Furnishing Facility) monthly to keep B2B clients' ITC flow uninterrupted. For most software OPCs with B2B clients, the simplification of QRMP is illusory because IFF monthly filing brings you back to monthly cadence anyway. Read the rules carefully before opting in. The default monthly filing is not as bad as the QRMP marketing implies.

Conclusion #

GST is the most operationally demanding module in this path because the cadence is monthly and the stakes are the bank account. The discipline you build here — invoice templates correct, LUT filed on time, monthly returns clean, GSTR-2B reconciled — is what makes every other module easier. Bookkeeping (Module 6) is where your invoices land; FEMA (Module 4) depends on the LUT being correct; Income Tax (Module 3) depends on revenue being reported the same way to GST and IT. Get GST right and the rest stops fighting you. Get GST wrong and every downstream module becomes a debugging session.

Predictions #

  • You will resent the monthly cadence for the first three months. By month four it will be muscle memory. Don't optimize the resentment away early; just keep filing.
  • You will forget the LUT exists until you are about to send your first export invoice of the financial year. Either set up a calendar reminder for early April now, or file it this week.
  • The GSTR-2B reconciliation will surface at least one supplier mismatch in the first six months. The mismatch will not be your fault. Chasing the supplier to fix it will feel disproportionate. Chase them anyway — it is cheaper than carrying a wrong ITC claim.
  • You will be tempted to opt into QRMP (quarterly returns) to reduce the cadence. Read what QRMP actually changes before opting in — it changes the return cadence to quarterly but keeps the tax payment monthly. The simplification is smaller than the marketing suggests.
  • The first time you file a GSTR-3B yourself (with your CA watching), you will discover at least one number you didn't understand the source of. That moment of "wait, where did this come from?" is exactly the moment the module starts paying off.
  • ClearTax's GST guides will become your default reference. Razorpay's blog will become your default for "how does this map to a SaaS workflow." TaxGuru will become your default for "did the rule change this year?" That triangulation is the operational shape of GST literacy.
  • Within twelve months you will have an opinion about which specific GST rule is genuinely badly designed (probably reverse charge mechanism on imported services, or the ITC blocked-credits list). Having an opinion means you have internalized the system. Welcome.
