Registering a Pvt Ltd in India typically takes 7–14 working days end-to-end. The longest steps are name reservation (RUN) and SPICe+ filing. Pick a name that is unique, available as a domain, and not a trademark conflict. Decide on authorised capital sensibly — ₹10 lakh is plenty for most starting startups. And do not skip the shareholders’ agreement, even between co-founders.
