Continuous supply of services

Hello, 

Understand that as per gst law as a service provider we are required to raise an invoice within 30 days from the date of service, however, if we sign an Agreement with the company and the agreement clearly specifies that the invoice will be raised only after 2 months from the date of service will it come under the Continuous supply of services section 2(33)? Can we raise the invoice after 2 months from the date of service under Continuous supply of services?

Thanks!
