A company headquartered at a place, if found to have a customer base in another country, might find it difficult in setting up the office in a speck of time.
Also, the trending fluctuations are easily captured by the corporates than anyone else at the fastest. The same fluctuations and trends will also reflect in the real estate market, which makes it difficult for corporates to take over space for an office.
Coworking spaces do not put the corporates in this difficulty and they can take up the spaces that they already have a connection with, or with the place, they find suitable for their works.
Also, with the land on lease, the budget and accounting must include the land lease for 1 year, (as it comes under the long term) under the liabilities of the company.
Coworking spaces provide you with the pay as you go facility, due to the short term lease, making it easier on their balance sheet too.
