A startup in Mumbai faces GST decisions that are disproportionately consequential relative to its size: when to register, whether the pre-revenue GST is recoverable, how to structure exports, and how to classify a multi-stream revenue model. The standard advice—register when you cross ₹20 lakh—misses the timing problem that determines whether the GST on setup costs becomes a credit or a sunk cost.
The Pre-Revenue ITC Asymmetry
Section 18(1) permits a registered person to claim credit on goods held in stock on the day before registration, through Form ITC-01 within the prescribed period. Services consumed before registration do not have an equivalent route. A startup that registers early enough to receive advisory, software and workspace invoices in its registered name preserves the credit; a startup that registers after the fundraising round may find the GST on those services has become a cost. The registration-timing decision should be modelled against the expected pre-revenue service spend.
The Export Architecture
A startup serving foreign clients should obtain a LUT in Form GST RFD-11, issue zero-rated invoices, maintain FIRC/bank realisation evidence, and claim refund of accumulated ITC. The five Section 2(6) conditions are cumulative; the establishment condition (supplier and recipient not establishments of the same person) is the one most often failed by startups billing a foreign subsidiary.
The Multi-Revenue Classification
A startup with subscription, commission, advertising and implementation revenue must analyse whether a bundled offering is a composite supply with a principal supply or a mixed supply attracting the highest rate. The contract, invoice and delivery should align with the chosen characterisation. A generic “software services” label across a diverse revenue base creates avoidable risk.
What the Consultant Does
The consultant assists with the registration-timing model, the LUT and export documentation, the composite-supply analysis, the ITC apportionment and the notice response. The value is in aligning the GST architecture with the funding and revenue model before the returns are filed.
