What is the fastest way for a foreign company to incorporate in India?

The single biggest delay in a foreign-promoter incorporation isn't Indian bureaucracy — it's the notarisation-and-apostille cycle each signed document has to clear in the promoter's home country before it can be filed in India. A Power of Attorney granted upfront to a locally authorised representative lets that representative sign and file the majority of incorporation documents — SPICe+ forms, declarations, and related registrations — directly in India, without routing each one back abroad. That structural change is what typically compresses a multi-month process into 5-6 weeks.
