The short answer
Start before a prospect asks, because the timeline is the problem, not the cost. A SOC 2 Type 1 is a point in time snapshot you can get in weeks to unblock one urgent deal, but Type 2 needs an observation window of at least three months, so if you wait for the first enterprise buyer to demand it you have already lost a quarter. Underneath the certificate the controls are unglamorous and cheap: single sign on with enforced 2FA, protected branches and reviewed deploys, centralised logging, device management, and a list of your vendors. Selling in India adds the DPDP Act, so have a DPA that names you as processor, your subprocessor list, and your breach notification commitment ready. And do not expect the certificate to end questionnaires. It changes them, from basic control checks to specific questions about your data residency and subprocessors, so build a reusable answer library.
